This week, Jessica sits down with David Salazar — the son of immigrant farmworkers and the winemaker, owner, and visionary behind Reclamación Wines. From his upbringing in agricultural roots to earning a degree in Viticulture and Enology from Fresno State, David's journey has taken him across wine regions from Paso Robles to Napa Valley and as far as New Zealand. In this episode, David opens up about why he launched Reclamación Wines — a bold, intentional brand that challenges the narrative that Latinos are only seen as labor in the wine industry. His mission is clear: to elevate Hispanic voices and showcase the leadership, innovation, and brilliance Latinos bring to winemaking. Jessica and David dive into cultural reclamation, the storytelling behind the wine, and, of course, Jessica shares her first sips and real-time reactions to his beautiful wine. In This Episode: The story and meaning behind Reclamación Wines David's journey from immigrant roots to global wine regions His mission to shift narratives in the wine industry The role of culture, identity, and family in his work Jessica's tasting notes and reactions to the 2021 vintage About David Salazar: David is the son of immigrant farmworkers and a proud graduate of Fresno State's Viticulture and Enology program. His experience spans top wine regions from California to New Zealand. David's passion lies in reclaiming space and respect for Latinos in the wine world — not just as laborers, but as leaders, innovators, and great winemakers. Connect with David Salazar:

DET DOFTAR DYRT. Mathias dricker honungsvatten med näsdukar och hostmedicin i, vi andra tittar snett på vår boråsman och dricker whisky. Vi träffar återigen Ekkramaren Roger Melander, master distiller på High Coast distillery. Hur påverkar klyvningen eken? Varför läcker Mizunara-ek som ett såll? Vad har whiskytunnorna för likhet med en köksfläkt? Vi lär oss också att det finns 6:th fill och 7:th fill-tunnor, men det anses ocoolt att prata om dem. Dessutom självplock av tunnor, änglarnas andel och saltstänkta lagerhus. Vad var det i glaset då?

Fred Peterson has been making wines in Sonoma County for more than 40 years.  While attending UC Santa Cruz, he took a job in a classmate's family vineyard in Mendocino County and he found his passion. He left Santa Cruz, and used the rest of his GI Education benefits to attend UC Davis. Photo: Peterson Winery. Credit: Wine for Normal People   Fred got his bachelor's degree in Viticulture and Enology in 1978. And after managing vineyards for a large winery in the Central Coast, he moved to the Dry Creek Valley of Sonoma in 1983. That same year, he planted a vineyard and built his house on Bradford Mountain.   In 1987, Fred hung a shingle on a red barn off of Lytton Springs Road and Peterson was born. The winery is no longer in the red barn, but it remains an important part of their history and is represented on every wine label with a back drop of Bradford Mountain, where the Peterson Estate Vineyard is located. Photo: Fred Peterson. Courtesy of Peterson Winery   In this (super dorky) show Fred takes us through some of the fascinating history of how philosophies about terroir and soil have changed since he started as a grower and winemaker in the early 1980s and how he has managed to be a leader in sustainable, but not dogmatic sustainable farming and winemaking.  Fred was one of the first voices in Sonoma to promote low intervention farming and winemaking.

Nick Papagni, “The Ag Meter” and Lorrie Boyer, the Ag Net News Hour hosts discussed recent updates on water issues between the U.S. and Mexico, including a water pact violation leading to crop and livestock losses in southern Texas and Mexico's refusal to allow U.S. aircraft to release sterile insects to control the screw worm. Secretary Rollins is working to resolve these issues. Additionally, the show featured an interview with Todd Burkdoll from Valent USA, who provided insights on almond farming, emphasizing disease control, fungicide application, and weed management. He highlighted the importance of timely interventions to prevent diseases like Salton and Paramount, and controlling pests like leaf-footed plant bugs. Nick and Lorrie also shared an email from listener on a recent show topic where they talked about the impact of artificial food dyes on children's behavior. The listener shared a positive experience after removing red dyes from her child's diet. The show then shifted to vertical farming innovations, highlighting Nature's Miracle Holding Incorporated's plan to purchase up to 100 electric vehicles equipped with hydroponic systems to grow microgreens and herbs. These vehicles will operate in Los Angeles, aiming to reduce water usage by 90% and deliver fresh produce directly to consumers. The initiative is expected to start in Q2 2025 and may benefit from state and federal subsidies. The University of California, Davis, has introduced a new Viticulture and Enology minor to attract students to the wine industry, offering a blend of science and business education. The program aims to increase the number of graduates in the field, which has seen a decline in student enrollment. The hosts discuss the importance of innovation and business acumen in the wine industry, highlighting the need for students to network and gain practical experience. They also touch on the growing popularity of non-alcoholic and low-sugar wines, suggesting potential for traditional wineries to adapt. The segment concludes with a light-hearted discussion on farming facts and personal preferences for different types of poultry and meat.

Dichotomy is a Washington State vineyard and winery born from winemakers Jarred Jenner and Rosie Signer after they fell in love on the coast of South Australia. Rosie grew up in Spokane Washington and studied Viticulture and Enology at WSU before heading to Australia, where she fell in love with the terroir and Barossa born and bred winemaker, Jarred Jenner.  In 2021 Jarred and Rosie banded together in 2021 and started the Dichotomy brand in Australia crafting small batch wines from beloved vineyards in McLaren Vale, Barossa, and the Adelaide Hills. In 2022, amidst the challenges of Covid-19, they took a bold leap of faith by purchasing a dormant winery and vineyard in Yakima Valley without ever seeing it in person. With just six suitcases, their young children, and their beloved dog Yeti in tow, they embarked on this new adventure. Despite their unfamiliarity with the area, the promise of Yakima Valley's renowned wines and the allure of the vineyard's mature 30-40-year-old vines compelled them to dive in.

The phenomenon of red wine headaches, documented since Roman times, has puzzled researchers for centuries. While sulphites, biogenic amines, and tannins have been blamed, new research points to quercetin, a phenolic compound abundant in red wine, as a more likely culprit.

What causes the “red wine headache”? Is it sulfites? A histamine reaction? Andrew Waterhouse, Professor Emeritus of Enology in the Department of Viticulture and Enology at UC Davis and Apramita Devi, Postdoctoral Scholar in the Department of Viticulture and Enology at UC Davis have identified a flavanol that can interfere with the metabolism of alcohol. That flavanol is quercetin, a natural product made in grape skins in response to sunlight. It is a natural sunscreen produced to protect the fruit from ultraviolet light. This conversation covers why quercetin may be more prevalent in high end wines, how skin contact during wine production impacts quercetin levels, and why sulfites may play a role in “red wine headache”.

[00:02:01] Craig Macmillan: Our guests today are Andrew Waterhouse, Professor Emeritus in Enology in the Department of Viticulture Davis, and also Aparmita Devi. She is a postdoctoral scholar, also in the Department of Viticulture & Enology Davis. Thank you both for being here. [00:02:17] Andrew Waterhouse: Oh, we're glad to be here. [00:02:19] Craig Macmillan: Today we're going to talk about a really interesting topic. It's the role of quercetin , in wine headaches. The two of you recently co authored a paper on this one particular mechanism that might cause some people to get a headache after drinking even a small amount of red wine. But before we get into that, I want to ask you, how did you get interested in this topic? [00:02:37] Andrew Waterhouse: Well I've been talking to Steve Mathiasson. He's a Napa winemaker for actually quite a while, some years back. He suffers from headaches when he drinks certain wines. And we were chatting about possible mechanisms, and we even did a study many years ago with another postdoc in my lab to investigate a question we had or a theory we had, and that didn't pan out. But more recently we were chatting again, and I got interested in the topic again, and that's what got me interested, you know, just somebody knowledgeable who was suffering from headaches and. for listening. It was, it makes it more real and it's like, well, maybe we can figure something out. So that's what got us started. [00:03:17] Craig Macmillan: Apramita , how same for you. [00:03:19] Apramita Devi: Yeah. Same. Like I've been in touch with Andy and we have been talking about this project many years. So I was always interested because I come from biological science and metabolism and stuff I got interested after talking to Andy. [00:03:33] Craig Macmillan: Well, let's start with some basics. What is quercetin? [00:03:38] Andrew Waterhouse: Well, basically, it's a natural product made by grapes, but it's a very specific one. It's in the class of polyphenolic compounds, and it's in the class of flavonoids called flavonols. And what makes it interesting, I think, is that it is made By grapes, in the skin of the grape, and only in the skin of the grape, in response to sunlight. It's sometimes referred to as sunscreen for grapes. And it specifically absorbs UV light that would cause damage to, say, DNA and other macromolecules. So it's very clear that the grapes are producing this in order to protect themselves from ultraviolet light. [00:04:22] Craig Macmillan: Right. [00:04:22] Andrew Waterhouse: So the amount that's present in wine is highly dependent on the amount of sunlight the grapes experience. Not the vine, but the grapes themselves, And a friend of mine, Steve Price, was the first to note this. In a study way back in the 90s on Pinot Noir, he noted that there was more quercetin in sun exposed Pinot Noir grapes. And that observation has been confirmed many times now in different studies. where sun exposure is correlated with quercetin levels. [00:04:58] Craig Macmillan: and this is true just for red grapes as opposed to white grapes. [00:05:02] Andrew Waterhouse: Oh, no, no, there's more in white grapes. But when you make white wine, you throw away the skins. So there's no opportunity to get those materials into the wine. Now, an exception might be orange wine. But I don't know of any data on orange wine. [00:05:21] Craig Macmillan: Apramita , maybe you can talk about the metabolism part, the biology part. So when people consume alcohol, it's metabolized down certain pathways. Quercetin is also metabolized by the body into other forms? [00:05:33] Apramita Devi: Yeah, so the pathway for alcohol and quercetin are a bit different, but the location is liver, where it goes. So when people consume alcohol, it goes to the liver and then there are two enzymes which work on the alcohol. So the first enzyme is alcohol dehydrogenase, which convert it into alcohol into acetaldehyde. The acetaldehyde is the like the toxic metabolite in the body and it can have many side effects. That's why body has to get rid of it out of the liver system. So it has a second enzyme which is called the acetaldehyde dehydrogenase. So that convert acetaldehyde dehydrogenase into a non toxic component, which is acetate or acetic system. [00:06:24] So it comes out of the body. What happens when you consume quercetin along in the body, the quercetin also goes to the liver. Because quercetin adds too much quercetin as such is not good for the body and it has low bioavailability. So liver tag it in the form of quercetin glucuronide and then the body knows that it has to be flushed out of the system. So the interesting part is that when you consume alcohol and quercetin together, You are taking the both the metabolite acetaldehyde and quercetin gluconide in the same location inside the liver. And it gives the quercetin gluconide to interact with the acetaldehyde dehydrogenase enzyme. And that acetaldehyde dehydrogenase enzyme now cannot work efficiently. to convert the acetaldehyde into the acetate. So basically you are building up acetaldehyde in the body and it's not coming out of the system and you are seeing all those negative effects of the acetaldehyde in the form of flushing or headache or not. The other systems like what's like sweating. so we think that there is a correlation between these two pathways, which might be associated in red wine system. [00:07:47] Craig Macmillan: And how did you design your study? [00:07:51] Apramita Devi: The first when I talked to Andy, like he told me that he thinks that this system is because of inflammatory pathways and inflammation system. So he was kind of like, there is something in red wine, which is Triggering this kind of pathways or there is some system so, but we were not sure what exactly are those inflammatory system. [00:08:16] So we went back and saw some literature and we kind of find that there are some studies which told that quercitans inhibit the dehydrogenase enzymes and that what triggered us that okay alcohol is metabolized by these dehydrogenase enzymes. And wine also has these phenolics. So what kind of phenolics, other kinds of phenolics, or what types of phenolics can do this inhibition? [00:08:45] The method was basically in, was based on having different phenolics, which are present in red wines more compared to white wines, select them. And then just, we find this enzyme kits in the market to do this dehydrogenase. Inhibition tests like you put the test compound and it tells whether the enzyme is the inhibited or not. [00:09:09] So we just did that in a test tube system, like we added our phenolics with the enzyme, and we saw that which kind of phenolics are inhibiting this enzyme and screening them out. out of all. So while doing that, we screened different types of quercetin, like quercetin glucoside, quercetin galactosides, and other forms. [00:09:32] Then we also tested other phenolics. I can for all my rest in and other stuff. And we also choose quercetin gluconide because that is the metabolite which is circulating in the body. And then we kind of screen them based on the in the enzyme system and we see how much inhibition is happening there. [00:09:54] Andrew Waterhouse: Yeah. So what we did was a very basic test to experiment. We didn't test anything on people. [00:10:01] We basically tested to see which of these compounds could inhibit that enzyme because we knew that if that an enzyme could be inhibited the acetaldehyde would accumulate and you'd end up with people in that condition would end up with Flushing, headaches, as Aparmita said, all kinds of other symptoms. [00:10:20] Craig Macmillan: And this would vary by person. Different people may have a proclivity to produce more of certain enzymes than others. Is that true? [00:10:29] Andrew Waterhouse: We don't really have any information about that. That's going to take a lot of more work to test you know, the, the details here. For instance. Some people get red wine headaches and some don't, but we don't know whether, for instance, perhaps their enzymes are more inhibited by quercetin glucuronide, or maybe they're just more sensitive to acetaldehyde. [00:10:52] So that's going to take, you know, human studies where we measure a bunch of things. And try to figure out, try to sort through the, the details of how this impacts people individually. [00:11:04] Craig Macmillan: What would a study , with people, investigating this, what would the design be like? How would somebody go about doing that? [00:11:12] Andrew Waterhouse: Okay. So a human study. Could have a couple different possible designs. The one we'll probably use is we'll simply find two wines, two red wines, one that's low in quercetin and one that's high. And then those will be administered to people who get red wine headaches. We'll give it to them blind, they'll have to agree of course to participate in the study. [00:11:37] And then we'll see if their experience of headaches is related to the quantity of quercetin. Now, there's some other designs we could imagine using, which might be a little more straightforward, but we're not sure how relevant they would be or whether we could get approval to do this. So, for instance, one approach would be to find a red wine that's low in quercetin and then simply add it. [00:12:00] Now adding it is tricky for a number of technical reasons. Quercetin itself is very insoluble, so we would have to add what's called a glycoside of quercetin. So we'd have to get our hands on something that would dissolve, et cetera, et cetera. We're not sure we could get approval for that because we're adding a chemical to wine. [00:12:21] Now, the chemical would probably be classified as a supplement, and so it might be approvable, as it were. And then another very simple experiment, which we thought about a while ago, you can buy quercetin as a supplement in the market. It's readily available. [00:12:38] So, one possibility is to simply give our subjects a glass of vodka and give them pills that either contain quercetin or a placebo and see if there's a relationship between administration of quercetin and headaches. [00:12:54] Now the, the quercetin itself, as I mentioned, is very insoluble. So we may have to get these more bioavailable forms of quercetin for that experiment. [00:13:04] Craig Macmillan: That leads to a wine making question. So, if it's relatively insoluble is quercetin extracted from skins more in the alcohol phase at the end of fermentation? [00:13:11] Andrew Waterhouse: Yeah. It's, it's, it's extracted fairly quickly because it's in the skin, in the grapes, it's in the form of what are called glycosides. So these, Has the quercetin molecule with the sugar attached. That makes all those forms very soluble. [00:13:27] Craig Macmillan: Oh, okay. Okay. [00:13:29] Andrew Waterhouse: There's actually an occasional problem with certain red wines, most commonly Sangiovese, where after bottling the wine has had a large quantity of quercetin glucosides. And after bottling, they break down, the glycosides break down, releasing just a simple a glycone, quercetin, and you get this disgusting looking gooey brown precipitate in the bottle. [00:13:56] Craig Macmillan: ha [00:13:57] Andrew Waterhouse: Every few years I know the folks at ETS in Napa get somebody showing up with a bottle of Sangiovese that's got this. Disgusting sludge in it, and they can tell them without analyzing that. Yes, another case, of course, it's in precipitate in the bottom. [00:14:15] Craig Macmillan: Huh, that's interesting. I believe it was mentioned in the paper that , obviously different growing conditions are going to lead to different levels of quercetin and grapes based on how much sun exposure they have, etc. And that also different winemaking techniques would have an impact. [00:14:29] If consumers are looking for products if they know they have a headache issue Is it possible they could experiment with different product types? Products that were made with different production methods if they can find that out that might Impact their sensitivity or might impact how often it happens [00:14:46] Andrew Waterhouse: Yeah, it's a pity that. Consumers wouldn't have information on the level of quercetin. We would very much like to do a study along those lines, but we haven't been able to find any funding for that, just in case somebody wants to support that kind of work, we're happy to work with them. but anyway you know, it hasn't really been an issue for winemakers, so there isn't a lot of data out there. [00:15:08] There are a few studies that published amounts of quercetin, you know, in wines from different places, but the data is very, very limited and not really useful in providing consumers guidance. The one thing we can say is because, as I mentioned earlier, sun exposure is very important, in general if you look at a particular type of wine, a varietal, say Cabernet or Pinot Noir, that the grapes that are grown on very large vines, will have less sun exposure. [00:15:39] Essentially if you have a very highly productive vineyard making targeting an inexpensive line, you probably have much more shading of the fruit as a consequence of lower quercetin levels. Compared to a very high end vineyard, usually, the amount of sunlight is very tightly controlled, and one of the reasons for that is that there's very good data showing that wines that are high in quercetin have a better mouthfeel, better texture in the mouth. And it's not clear whether quercetin is directly responsible or whether it's a marker for something else that's produced under those conditions that leads to that. many years ago, we did a study looking at phenolics in Cabernet, and we observed that the very high end Cabernets that we tested were much higher in quercetin than the sort of average price type product. [00:16:35] And I think that that was true then. It's probably true now that, you know, a very good cabernet is, is made with very tight control of sun exposure. And there is a fair amount, of course, it can't be a complete sun exposure, or they probably get raisins by the end of the harvest, by the time you get to harvest, but there's a very deliberate management of sun exposure in high end wines. And it's for a reason to, get to higher quality product. [00:17:04] Craig Macmillan: Right, exactly! And, We know that the managed sun exposure, quercetin is a part of it but also it's connected to just total phenolics in general. Lots and lots of different compounds that are, you know, semi related. And I actually wanted to go back Aprametia you identified the quercetin glucuronide as being The highest in the ones that you tested, were there other things in that test and that assay that all were also stood out, maybe not as high as that, but really kind of stuck out as being different than the rest. [00:17:39] Apramita Devi: Actually, the quercetin gluconide was a standalone as a very high, like it's like 78%. The other things were around in that 30 percent range, so I'm not sure how significant was the impact of that, but there were quercetin glycosides forms, which were like around 30 percent inhibition of the enzyme, but [00:18:03] all others were very low. [00:18:04] Craig Macmillan: yeah, so it really stood out basically as it was head and shoulders above it. I would like to put this work into context a little bit. I, I work with the public quite a bit as part of my job and I have for years. And this topic comes up. All the time. This information definitely helps me my goal, when I talk to a consumer that has an issue with, wine headache or whatever it's not that I'm trying to sell them a product as much as it is. [00:18:29] They want to enjoy wine. They tell me this, they say, Oh, I love to have it. I just can't. Da da da. And then they'll say, it's like sulfites. And then I'll kind of explore that with them a little bit. Like, so can you eat dried fruit? Do you eat canned fruit? Do you have reactions to this or to that? Are you asthmatic? [00:18:48] Kind of sort that out and go, okay, I don't think maybe that's it. Maybe it's not. The other ones that I just learned about about 10 years ago was a biogenic amines, which made a lot of sense to me in terms of things like histamine reactions. What is your feeling about sulfites is contributing biogenic amines. [00:19:04] Maybe there's other things we haven't hit on, on this topic. What are your feelings about the, kind of the big picture of what potential for a diagnosing assist? [00:19:15] Andrew Waterhouse: Why don't you talk about amines [00:19:16] Craig Macmillan: Yes, please, [00:19:18] Apramita Devi: Biogenic amines like mostly the histamine and tyramine are the main ones people talk about whenever they come with this headache stuff. So I think because it's formed in the wine during the fermentation process, and there are these spec microbes which can convert the amino acids into this, biogenic amines the histamines are part of inflammatory reactions. People know that in biology and immunology. So it's very easy to be people connected that it might be a reason why people get headache. But what I always focus is like, there are far more other food products, for example, fermented meat products, which has far more higher amount of these biogenic amines. do people get headache if they have something similar with alcohol eating together with alcohol or something like that? But there is no mechanism told till now, they just tell that, oh, since it's histamine and it's related to this inflammatory reactions, it might be the cause. But there is no solid proof that it is the cause. [00:20:27] so I don't know whether it's there or it might be a pathway or not. [00:20:33] Craig Macmillan: One of the things that I find fascinating is how we evolve our, Hypotheses about things over time, and somebody has an hypothesis and they test it out, maybe they find something, maybe they don't, but then that kicks off this whole set of what I call naive science making up stories about why. [00:20:53] It's kind of a just so story. It's like, well, obviously then somebody comes along and checks it and says, Hey, wait a second. And we're no, or if this was true, then that would have to be true. And that's not true. You know, and that kind of thing and how we keep coming around to new ideas, which is what you folks have done, which I think is really, really cool. [00:21:10] Andrew Waterhouse: I was going to answer your question about sulfites. It's a really big question actually. Partly because sulfites have so much visibility and there's so much concern about it. I think sulfites themselves Have been studied pretty carefully there's one study where if they gave subjects a very high level of sulfites in wine, it was like very small, but statistically significant increase in headaches. [00:21:39] Or some adverse reaction, but other studies have shown no correlation. By the way, sulfites are antioxidants in case you hadn't heard that. So it seems very unlikely that sulfites by themselves are some sort of bad actor in this regard. Like you, I get these questions all the time. And what I heard so many times was. Oh, it's cheap wine. It gives me a headache. [00:22:06] Craig Macmillan: Yes. [00:22:07] Andrew Waterhouse: And have you heard [00:22:08] Craig Macmillan: I've heard that many times. And then on the opposite side of things, I've heard stuff like, Oh, I get headaches from American wine, but I don't get it from French wine. Or I always get headaches from European wines, but I never from California wine. So I'm trying to figure out, is there something going on? [00:22:26] Like, can you be allergic to burgundy? You know what I'm saying? Cause I mean, it could be, it could be something about burgundy. It's just stuff going on. And then the opposite. I had a guy who says, no, I don't have any that. But he says I was traveling in France, and we were drinking wine like it was water, and I never had a hangover symptom, and I did it, and I was like, I don't know dude, like I [00:22:45] Andrew Waterhouse: Yeah. Well, there's, there's one answer to some of this, which is if you're on vacation and you don't have to get up early and you're relaxed and you probably don't get as many headaches. [00:22:58] Craig Macmillan: Right. [00:22:59] Andrew Waterhouse: So I think that's a large part of it, especially for Americans visiting Europe. They're on vacation. but I think there is something to the sulfites question. And that is that inexpensive wine often, not always, but often has more bound sulfites. [00:23:18] Craig Macmillan: Yep. [00:23:19] Andrew Waterhouse: And this is probably because those grapes have a little bit more mold on them or a lot more mold. And when they get to the crusher, the winemaker goes, Oh, there's mold on these fruits. So we're going to add sulfites to, to take care of the botrytis, right? [00:23:34] We don't want the fruit to get oxidized and damaged. They had a bunch of sulfites. The consequence of that is that in the finished line, There's a lot more. Bound to SO2, which shows up in the total SO2 number. [00:23:47] You know what it's bound to? [00:23:49] Craig Macmillan: No. [00:23:49] Andrew Waterhouse: It's bound to largely acid aldehyde. [00:23:52] Craig Macmillan: Really? [00:23:53] Oh! Well that would make sense. Yeah, that would make sense. [00:23:56] Andrew Waterhouse: And the, the reason for that is that during the fermentation, the yeast are converting all this sugar the alcohol, but there's an intermediate step which is acetaldehyde. [00:24:06] Craig Macmillan: Right. [00:24:07] Andrew Waterhouse: If you have SO2 floating around, as you would if you'd added a lot of it up front, it binds that acetaldehyde before it gets reduced to ethanol, to alcohol. if you start a fermentation with a high level of added SO2, then you will end up with a wine that has more bound acetaldehyde. And that could be a marker, say, of less expensive wine. [00:24:31] So it's possible that those people are, what they're experiencing is direct ingestion of acetaldehyde, which is being released into the blood and that that's causing them a problem. [00:24:45] Now, I've looked and looked, and I cannot find any data on what's called absorption of acetaldehyde from wine, or from food for that matter. I keep, I'm going to keep looking, [00:24:56] but for some reason or other, this hasn't been subject of a published study, although maybe I just haven't been competent enough to find it. [00:25:05] Craig Macmillan: I doubt that. [00:25:07] Andrew Waterhouse: Well, sometimes these are, you know, they're very specialized and they're indexed in funny ways. And, [00:25:13] You know, and the other thing was, you know, when the study came out, I had all these questions. I was talking to this one reporter and she said, well, I can drink natural wine. [00:25:24] It doesn't give me headaches. And I was like, oh boy, what's this about? [00:25:27] Craig Macmillan: Yeah. [00:25:28] Andrew Waterhouse: But thinking about that further when you make natural wine, you don't add any sulfites or at least you're not supposed to, Right. And consequently in the finished wine, the level of acetaldehyde would have to be very low or else it would smell like sherry. [00:25:41] Craig Macmillan: Right. Right. [00:25:43] Andrew Waterhouse: And yes, granted, many natural wines have funky smells, but they don't by and large smell like sherry. [00:25:49] So it's possible that natural wines have in general, Much less acid aldehyde than conventional one. you know, all these questions have brought up some interesting issues, I think, you know, the industry should be looking into you know, these are these issues like how much acid aldehyde Do we want in our wine and how can we reduce it if we want to reduce it? [00:26:15] I don't think anybody's really looking at that yet. I think that would be a very interesting question to pursue. Oh [00:26:24] Craig Macmillan: you just, you just reminded me of, of something two things that I, I had forgotten about. One I used to teach like enology for babies, enology for dummies thing for the public. I am in no way qualified other than just experience to do that. [00:26:39] But I broke it down in that I do that sugar aldehyde, alcohol arrows, and I'd say, okay, this, this acid aldehyde. Remember this one? This one's coming back. We're going to see this again later. So write this one down. We're going to get to that later. And sure enough, now it's just through the body and, and I think breathalyzers work based on that. [00:27:00] Don't they? It's like density. Something like that. So the aldehyde, they're actually, [00:27:05] I think so. I got to look that up again, but because by the time it gets to your breath, your body's, Processing it, right? Hugely important. Not just that compound, but aldehyde is just kind of a general well, maybe we should all invest in like some kind of, I don't know, AO unit or wine X ray or something at our house. [00:27:21] And then we could get the totals and know before we drink it you know, maybe we could figure out if somebody could come up with a consumer friendly, you know, put it in a vial and shake it and it turns blue. Don't drink it kind of thing. I'm just being silly. I don't know. [00:27:34] Andrew Waterhouse: idea. [00:27:35] Craig Macmillan: You go to different like wine shops and stuff, and there's all kinds of stirs and additives and strainers and funnels and stuff that are supposed to take things out. [00:27:45] And I've always really wanted to see what those things do. They do anything or not, or I don't know. I'd like to try it. Finally, is there one takeaway on this topic, this question to both you, one takeaway you'd like people to know, I [00:27:57] Andrew Waterhouse: well, I think the key thing is that we haven't done any experiments on people yet. [00:28:03] Craig Macmillan: Right. [00:28:04] Andrew Waterhouse: And so what we have here is, I would call it a well founded theory, [00:28:09] Craig Macmillan: Mhmm. [00:28:09] Andrew Waterhouse: I think people shouldn't rush out and start changing the way they drink yet. They might want to try some experiments. But we don't have the final word yet. [00:28:20] Craig Macmillan: Right, right. [00:28:24] Apramita Devi: Same. Yeah. This is just very preliminary study. And we just have a theory out. So we still don't know, like, what happens in the actual body. [00:28:34] Craig Macmillan: Well, I hope that we can do that. [00:28:36] Andrew Waterhouse: We're always looking for support for experiments. If anybody wants to support that, get in touch. [00:28:43] Craig Macmillan: You know, another creative thought that I have when I'm preparing for this is like, you know, , people either get headaches from wine or they don't. If I'm someone who wants to enjoy wine, but gets headaches, I would be really attracted to a product that had a back label if we could make health. statements, which we cannot, that would say now low in quercetin or, you know, headache free, you know, no, we would never get that through TTP, obviously, but but, but, you know, but we went round and round with that on sulfites, you know you know, organic waste, no added sulfites, you know, you can say that. [00:29:14] Andrew Waterhouse: I think it would be possible to perhaps have a declaration on a bottle about the level of quercetin, whether it's high or low. I suppose. I don't know. [00:29:24] One company did get a label through that had resveratrol levels on it, but then TTB stopped approving that. So only one company has that approval. But I think in that case the reason for denying the label is that it is a proxy for health claim. Thank you. [00:29:44] Quercetin, you know, whether it's high or low is really, it's not, it's not making a health claim. We're not claiming that this wine is healthier for you than the other has to do with headaches or not headaches. [00:29:55] And I don't see that as really a health claim. [00:29:58] Craig Macmillan: Well, let's just see how this develops. You never know. Let's face it. I mean, we're talking about nutrition. This is August of 2024, the date for this recording. We're talking about having nutritional labeling on wine. Right? Which I think would be a very interesting nutritional label, quite frankly. [00:30:13] I would, I would love to see that, you know. Zero percent of the RDA of everything, again, at the end of one of my lectures I'd introduce potassium, and at the end I'd say, so how much wine do you have to drink to get your RDA of potassium? You have to drink a gallon and a half of wine a day. So, maybe not a big contributor. Maybe not a big contributor. Where can people find out more about both of you? [00:30:37] Andrew Waterhouse: Well, I think probably the best starting point would be our LinkedIn pages. [00:30:43] Craig Macmillan: And those will be in the show notes. [00:30:45] Andrew Waterhouse: and I do have a website at UC Davis called waterhouse. ucdavis. edu. [00:30:52] Craig Macmillan: And that will be in there as well. What about you, Apremita? [00:30:54] Apramita Devi: For me, LinkedIn page. [00:30:58] And if people want to see about my research or my past research, they can go to my Google Scholar page to [00:31:05] Craig Macmillan: Awesome. Thank you. Well, thanks so much for being here.

[00:31:55] Craig Macmillan: This is out in the world now. [00:31:57] Andrew Waterhouse: It's just out this month. [00:31:59] Craig Macmillan: That sounds like a must have. [00:32:01] Andrew Waterhouse: I agree. [00:32:03] Craig Macmillan: That sounds like a must have. , I will leave the name out, but there was a very famous book written by a group of folks from CSU Fresno and some collaborators. And I don't have a copy because I bought five copies in my cellar. People stole them every single time. So, this is the same kind of book, folks. [00:32:20] Maybe buy five copies. And just hand them out to give one to your assistant winemaker. Give one to your cellar master and just say, here, these are yours. I'm keeping my copy. Thank you very much.

This is the second installment of an in-depth series on the Rioja DOCa, where I do a close look at the three major zones of Rioja. I host top producers in each show to tell us about their areas and the challenges they face.   In Episode 544, we heard about the Rioja Alta zone and this week we hear from Tao Platón of Rioja Alavesa, who presents a completely different perspective on the region.   Tao Platón graduated in Enology from the University of Valladolid, holds a WSET Diploma and is an Master of Wine (MW) candidate.

Credit: Península Vinicultores He leads the production of a new generation of terroir-driven wines from Rioja Alavesa at Bodega Bideona. Bideona cultivates hundreds of individual parcels and makes wine in the Burgundian model – terroir-driven, vineyard specific wines. He joins us as a representative of the zone of Alavesa and as a passionate advocate for the system of terroir-driven, single vineyard wines, a system which Rioja approved in 2018.   We discuss:  The Rioja Alavesa overview -- terroir, the history of the region, and how Alavesa is made up of many small, family owned wineries.   The strengths of Alavesa, which are old vines, mainly of Tempranillo. Wineries of Alavesa don't blend grapes from elsewhere so the wines are very terroir-driven and local in Alavesa. We discuss the various styles of wines, including the production of whites in the region.   We get to some of the very hard questions regarding Alavesa and its Basque identity. We fill you in on the political independent movement in the Basque Country, the various ideologies and how those are playing out in the politics of the Rioja DOCa.   The differences between business models (traditional model versus newer, terroir driven producers) in the Rioja DOCa, as well as the tension is between quality producers and those who look to make cheap wine that they can sell quickly, regardless of quality.   The potential future for Rioja and the DOCa and various scenarios that could exist for Alavesa in the future. ____________________________________________________  This show represents a totally different perspective from Rioja Alavesa versus Rioja Alta!

The BanterThe Guys talk about what Robert Simonson calls “the cold switcheroo” and what's next in the world of martini. The ConversationThe Restaurant Guys get two Corisons on one show! They catch up with Cathy Corison and her daughter Grace Corison Martin who will, perhaps along with her sister, take over the winery one day. They discuss the challenging past, bright present and brilliant future of Corison Wines. The Inside TrackThey have been avid fans of Cathy Corison's wines (Corison Winery) and they have hosted wine dinners at their places with Cathy and she has hosted them when they visit in California. On the idea of her daughters eventually taking the reins at the winery, Cathy says,“I'm just so grateful to know that it's going to go forward after me because we're farmers.  It's a very long term business.  And in fact, the wines I'm making today are still going to be on the youthful side when I'm gone. So just to know that it's going to go forward is, is very, very gratifying,” Cathy Corison on The Restaurant Guys Podcast 2024BioCathy Corison's winemaking journey began nearly 50 years ago when she took a wine appreciation course. Two years later she graduated, and two days after that, arrived in the Napa Valley, bent on making wine. A master's degree in Enology at UC Davis followed. She made wine at Chappellet Vineyard for the 1980's. In 1987, toward the end of her tenure at Chappellet, there was a wine inside her that she needed to make and she began to buy grapes and barrels. Using other wineries' facilities, she was able to create the wine of her own.She founded her own winery, Corison Winery, in 1987. The winery is located in St. Helena, California in a barn built by Corison's husband, William Martin. They have two daughters, Grace and Rose, who are poised to take the reins in the future. Grace Corison Martin earned a BFA in Acting from Syracuse University and then worked in restaurants in NYC. Since moving back to the Napa Valley, Grace completed her Winemaking Certificate at UC Davis, and her Level 3 WSET.InfoCorison Wineryhttps://www.corison.com/See the Kronos table!https://www.corison.com/about/Our Sponsors The Heldrich Hotel & Conference Centerhttps://www.theheldrich.com/ Magyar Bankhttps://www.magbank.com/ Withum Accountinghttps://www.withum.com/ Our Places Stage Left Steakhttps://www.stageleft.com/ Catherine Lombardi Restauranthttps://www.catherinelombardi.com/ Stage Left Wineshophttps://www.stageleftwineshop.com/ To hear more about food, wine and the finer things in life:https://www.instagram.com/restaurantguyspodcast/https://www.facebook.com/restaurantguysReach Out to The Guys!TheGuys@restaurantguyspodcast.com**Become a Restaurant Guys Regular and get two bonus episodes per month, bonus content and Regulars Only events.**Click Below! https://www.buzzsprout.com/2401692/subscribe

Doug Nalle, co-founder of Nalle Winery, is our guest today on California Wine Country with Steve Jaxon and Dan Berger. The last time Doug was on the show was this episode of April 19, 2023. Doug Nalle and Dan Berger have been friends for fifty years. They have three Chardonnays to taste. First, a 2021 Chardonnay from Hopkins Ranch. Doug and his wife Lee founded the winery in 1984 and they just finished their 41st harvest. They produce about 2000 cases per year. Mostly they make Dry Creek Valley Zinfandel. Their Chardonnay is about 200 cases. Doug's son Andrew is the winemaker now. He got a degree in enology from Fresno State. His wife April is a viticulturalist who went to Australia for training and works with the winery. They have roughly 24 acres of grapes and they use some and sell some. His wife's family bought property in Dry Creek Valley 95 years ago and it is still in the family. Visit Chigazola Merchants online to shop their unique selection of fine Italian wines. Doug has brought two 2021 Zinfandels. Dan describes the Nalle property as “spectacular.” They have an above-ground cave. It is grade level with retaining walls on two sides. There are 6 feet of dirt stacked inside the walls, so the interior is naturally cool like an underground space. Back in the 80s and 90s Zinfandel was a moderate alcohol wine, between 13 and 14 % ABV. Then the trend was for higher ABV but Doug did not follow that trend. Vertical tasting of 3 Chardonnays They are tasting the 2021, 2022 and 2023 Chardonnays from Bob and Tony Hopkins' vineyard in Russian River Valley. The 2021 is smooth and pure fruit. The 2022 has an extra layer of something. Nalle Winery is open Friday Saturday and Sunday and maybe other days too at 2383 Dry Creek Road. Exit in Healdsburg and go west about 2.1 miles to their sign. The 2023 is young, obviously and has barely been bottled. It is interesting to taste one that is so young just to know where the wines start out. Then the starting point for aging is five years, in Dan Berger's opinion. Doug Nalle give credit to his son Andrew for the quality of the 2023. Andrew just finished a Masters degree in Enology at Fresno State. He studied particular strains of yeast and ways to use them. Zinot Noir Zinot Noir is something Doug and Andrew came up with by blending 60% Zinfandel and 40% Pinot Noir. They liked it for the forward fruit of Zin plus some "mysterious Pinot Noir thing going on." It is a modest 13.65 ABV and they made only 280 cases of it.  

Why do certain musty or animalistic aromas, like barnyard or manure, become more acceptable to wine lovers over time? What does minerality really mean when it comes to wine? Why is mouthfeel so important to appreciating wine? How does the colour of wine influence our perception of how it tastes? In this episode of the Unreserved Wine Talk podcast, I'm chatting with Master of Wine, Gus Zhu. You can find the wines we discussed at https://www.nataliemaclean.com/winepicks   Giveaway Two of you will a copy of his terrific new book, Behind the Glass: The Chemical and Sensorial Terroir of Wine Tasting. To qualify, all you have to do is email me at natalie@nataliemaclean.com and let me know that you've posted a review of the podcast. I'll choose two people randomly from those who contact me. Good luck!   Highlights Why do certain musty or animalistic aromas, like barnyard or manure, become more acceptable to wine lovers over time? What's behind the perception of saltiness and minerality in wine? How do we misunderstand sweetness when it comes to wine? Why have we developed more complex perceptions of bitterness, and how does it influence our experience of tannins in wine? Why is mouthfeel so important in wine tasting? How does colour affect our perception of wine? What are the most interesting aspects of oak aging in wine, and why is there so much diversity? Why is it important to embrace sensory differences in wine tasting?   Key Takeaways Gus believes that the wine industry or even the media is trying to promote a certain style of wine and make people believe that many people love wines that have specific smells and taste like barnyard. Gus observes that acidity and minerality are such vague terms and concepts that people in the wine industry discuss. When people say minerality, they may be referring to many different things. Mouthfeel adds several other dimensions to taste, which makes wine tasting even more interesting. When blind tasting, many people depend on smell but he encourages them to pay attention to the textual, tactile sensations from the wine as well. People usually look at the color first because it's straightforward, even though we could see colours a bit differently from each other. Even though we want to be objective, we cannot. We could be even more biased when we see things first. For example, there are already studies showing that if you color white wine as a red wine colour, and ask people to smell it, they came up with all these descriptors that are related to red wines.   About Gus Zhu Gus Zhu is the first Chinese national to become a Master of Wine. He works as a research and development scientist at Harv 81 Group, specializing in chemical analysis and sensory studies of aroma compounds in wine, cork, and oak. Gus holds a Master of Science degree in Viticulture and Enology from UC Davis, which he earned in 2017, and achieved his MW qualification in 2019. In addition to his research in flavor chemistry and sensory science, Gus is a professional wine educator, offering tutorials to wine enthusiasts around the world.         To learn more, visit https://www.nataliemaclean.com/308.

Can you learn to appreciate aromas such as spice, petrol, and even gamey or foxy notes in wine? And would you want to, or should you? How can you better understand the taste of umami in what you eat and drink? How do culture and lifestyle influence your perception of the aromas and taste of wine? In this episode of the Unreserved Wine Talk podcast, I'm chatting with Master of Wine, Gus Zhu. You can find the wines we discussed at https://www.nataliemaclean.com/winepicks   Highlights What was the moment Gus realized he wanted to make wine his career? How did it feel to become the first Chinese Master of Wine (MW)? Which aspects of Gus' multicultural education helped him pass his MW exam on the first try? What is Gus' book, Behind the Glass, about? What makes Behind the Glass different from other books on wine science? What are chemical terroir and sensorial terroir? What was the most surprising thing Gus learned while researching and writing Behind the Glass? Why is the concept of the “tongue map” wrong, and what do we now know about how our tastebuds work? How can you better understand the taste of umami? Can you learn to appreciate vegetal and herbal aromas in wine? How do terpenes present in wine aromas, and why do people like them? Why might supertasters be at a disadvantage in the modern world? How do culture and lifestyle influence your perception of the aromas and taste of wine?   Key Takeaways As Gus explains, we evolved to reject certain smells for our survival. For example, if a plant or fruit or food smells vegetal, it's a sign of under ripeness so it either doesn't taste good or isn't nutritious enough for consumption. In some cases, it could mean that it's poisonous. So it makes sense then that we may not like vegetal aromas in wine. In Asian countries, Gus says, they have a longer history with fermented food and drink. They also don't over season or over cook protein dishes so that the taste of umami remains. Umami comes from the amino acids in protein, but we often get confused because we combine our proteins with fat, salt, and other things. If you barbecue a mushroom and don't season it, the juice or broth released in the little dent in the mushroom is a savory, yummy, umami taste. Gus believes that we should pay more attention to what we eat and drink. He believes that people who like the Chinese experience a more diverse range of flavours and develop a greater appreciation for them. Similarly, we develop a greater vocabulary to express what we're eating and drinking when we think about it.   About Gus Zhu Gus Zhu is the first Chinese national to become a Master of Wine.

Today I'm joined by Richard McDonald. Richard and his wife, Aly McDonald, own Colorado Vintners and Cliff Dweller Wine. Their newest venture, Grand Valley Enology, is an on-site wine lab that provides juice and wine chemistry analysis to grape growers and winemakers in the Grand Valley. Richard's goal is to provide lab services for everyone, from commercial wineries to home winemakers, to improve the overall quality of wine coming out of the Grand Valley and to save everyone some money along the way. Richard has had an expansive career in the wine industry, working all over the world in some of the top wineries and vineyards. We chat about his experiences working around the globe, why he and Aly decided to open a winery and lab in Palisade after all that, and the best things about owning a winery in a relatively young wine region. Richard also expands on why he wanted to start a wine lab, why it's important to have a local lab resource, and what he and Aly are getting into next.

Like many that find themselves in this industry, Jessica started her path in a different field: Civil Engineering. She graduated from the University of Portland and worked as a Transportation Engineer in the Bay Area until finding her passion in wine. After careful thought, she made the leap into wine in 2014. While completing her Certificate of Enology from Las Positas College, she worked full time at a winery in Livermore Valley. The list of reasons Jessica loves the wine industry is long and all of them make it a well matched career path for her. She was fortunate enough to be given the opportunity to open up her own winery in 2023 and jumped at the chance to fulfil that dream. 

Williams Selyem winemaker Jeff Mangahas is back on California Wine Country with Steve Jaxon and Dan Berger. Jeff has been on CWC as recently as last February on this episode, and previously here in 2021 and before that, on this episode from 2018. Wine Country Radio GM Melissa Galliani has brought a bottle of Dry Creek Chenin Blanc. Dry Creek is a sponsor of the KRSH Backyard Concert Series and their Chenin Blanc is a popular favorite. “Really refreshing,” says Jeff. Williams Selyem has a rich history as one of the original Russian River Valley producers. Their first commercial release was in 1981. They have been making interesting, small-production wines in Russian River Valley and other nearby regions. Williams Selyem: Russian River Valley Pioneers Williams Selyem worked with the growers in Russian River Valley, such as the Rocchioli and Martinelli vineyards. They produce 52 different wines, in small lots. The are not easy to get so the way to buy them is through the website. Click the logo to visit Davis Bynum Wines. Jeff Mangahas joined Williams Selyem in 2011 and took over winemaking and viticulture in 2014. This year is his 24th vintage. They taste the 2022 Estate Chardonnay. They are also well-known for Pinot Noir and Zin. This Chardonnay is unique because it has 20 different Chardonnay clones all planted together in the field. It presents all the different flavors that are present in the different clones and it makes for a complex wine. Click the logo to visit our sponsor Rodney Strong for info on the 2024 Summer Concert series. Jeff's history as a winemaker started with his interest in science and biology. He majored in molecular and cellular biology at University of Washington. He was interested in research science and worked in cancer research. Wine was a hobby. He moved back east to Princeton University to work in the molecular biology department there. The change to wine as a profession was a romantic idea that he made happen by going to UC Davis for a Masters in Enology. Dan Berger would keep this wine for no more than 2 or 3 years to get it in the glass before the fruit flavors fade. Jeff tells about how they still use foot treading to press some grapes because there is no better method to get the results that he wants.

Aseptic Fruit Purees are here to discuss the comparison of fruit purees vs fruit concentrates. When it comes to flavoring your beers, puree vs concentrate is a question many brewers ask. We would like to help by showing the pros and cons of both. We will be addressing flavors, yields, cost, production, and any other questions. We will also discuss non-alcoholic beverage ideas and flavor trends. Phil Lauchland- Aseptic Fruit Purees Representative and Brewing Consultant I have a BS degree in Enology. I have been in the fruit, wine, distilling, and brewing industry for over 15 years. I grew up in a farming family of vineyards in Lodi, Ca. I started making wine with my dad. Before I knew it, I was graduating from Fresno State with a BS degree in Enology. I was a winemaker at Garba Wine Company and Vie-Del Company before I transitioned to beer. I was a brewer for Full Circle Brewing. As I was brewing there, I've got connected with Aseptic Fruit Purees by being a customer. Then one day I was offered an the opportunity with AFP and here I am! I've been loving connecting with other brewers in this position. I get to talk shop and share ideas for a living. Oh! and sell fruit puree. haha Spencer Moore- Brewer I began my career in 2015 at Calverley's Brewery in Cambridge, UK. It was a very traditional cask brewery. Through my time there, Calverley's grew significantly, and started brewing more modern and Americanized styles. I believe we were the first in Cambridge city limits to brew a hazy IPA. I moved back to the states in 2018 and went to Line Creek Brewing in Peachtree City, GA. I began my time there working in the cellar, learning packaging, and doing pilot brewing on their small system. Eventually found myself moved into the Head Brewer position. Moved to Ohio in the summer of 2020 to take on a brewing position at Wolf's Ridge Brewing in Columbus, OH. There I took on the role of a Lead Brewer of their production facility. I was then the Production Manager for Lock 27 Brewing in Dayton, OH. From January 2022 until January 2024. Also, I have my brewing certification through the Institute of Brewing and Distilling out of the UK.

Growing up as the son of a winemaker, Marcos was introduced to the wine world from a young age. He first completed his Bachelor and Masters degree in Chemistry at Imperial University London, and worked for a few years in the corporate world before realizing that he wanted to spend his future making wines. He went to the Provence and New Zealand to gain hands-on experience, and continued his journey to Adelaide in order to learn the scientific side of the discipline at Adelaide University, where he gained his Masters Degree in Enology. This life changing adventure was the starting point of an exciting life as a winemaker. Through his international exposure, Marcos acquired the knowledge of the latest practices in modern winemaking and his pioneering and inventive mind is constantly in search for improvement, from the smallest detail in the winery to experimenting with indigenous grape varieties. He simply loves every moment of the creation.The history of the Zambartas family in wine goes back to the 1970's, when Akis Zambartas, a then young man, went to France to study Chemistry in Lyon and then Enology in Montpellier. He returned to Cyprus as the first university educated enologist of the island and was set for a successful career at one of the major wineries of the island.https://zambartaswineries.com/

This Episode kicks off my new series of Podcasts focusing on wines produced from the Norton grape here in Virginia. In Episode #1 I recorded a conversation between the judges at the Homestead Norton Cup Challenge the weekend of November 3rd & 4th, 2023. It was during the lunch break before the judges finished judging the Final Four Norton wines that had made it into the final round that morning. It is an interesting insight into their thoughts.I especially enjoyed the conversation at the end between Dr. Bruce Zoecklein Professor Emeritus of Enology at Virginia Tech and Todd Kliman the author of the book Wild Vine which details the history of Norton and its origin dating back to 1823 and Dr. Daniel Norton.

We're excited to announce that Episode 61 of All Things Whiskey Podcast is live now!On this episode Hosts Mike Outcalt and Devin Mitchell welcome Dr. Tom Collins - Jackson Family Wines Endowed Professor of Viticulture and Enology at Washington State University to talk about his research; the impact barrels have on wines and spirits, and how certain levels of dilution in spirits can make them smell and taste the same.  Dr. Collins is an expert in distillation practices which he has been studying in his chemistry lab since 2015 to determine how the char and toast levels inside barrels filter harsher components of whiskey and other spirits while aiming to understand the chemistry behind this process.  More recently Dr. Collins has studied a close link between the aroma and taste of whiskies to determine how a certain level of dilution can make whiskies smell the same and further dilution can make whiskies taste the same.  Additionally we discuss the demand for new barrels, used barrels, barrel alternatives, and sustainability initiatives around barrels in the spirits industry.  We then open up the conversation to talk about Dr. Collins' favorite whiskies, brands, spirits, and discuss the future of his research.Don't miss this episode - it is a great opportunity to learn about barrel, taste, and aroma science behind the spirits that we know and love.Thanks again to our guest Dr. Collins!  Cheers and enjoy!Support the show

This episode features Kira Ballotta, owner and winemaker for the two brands celebrating past and present trailblazing women.  If a wine brand was a historical fiction novel, Olivia Brion would be the main character in that novel. Each bottle of wine tells a different “chapter” of her story. Life being somewhat more surprising than fiction, the stories of Olivia Brion are inspired by the full lives of real trailblazing women from history.  Cantadora is the natural evolution of Olivia Brion. Where Olivia Brion focuses on stories from history, Cantadora features women from today, giving back to the shared community in exceptional ways.  Our conversation in this episode ranges from Kira's background, the varietals she works with, the challenges of building small brands, and the women that Kira has partnered with in creating the Cantadora wines.

This episode features Amy Whiteford and Dave Phinney in a conversation about the development of the Our Lady of Guadalupe Vineyard in the Santa Rita Hills and Santa Barbara County AVA. Both Amy and Dave have independently been on the podcast before Amy back in 2014 and 2016. Our conversation ranges from their shared work background, the reasons for developing a vineyard in Santa Rita Hills, the characteristics of the site, the diversity of Pinot Noir and Chardonnay selections, challenges of hillside plantings, avocado trees in the vineyard, straddling the AVA line, the name Our Lady of Guadalupe, the wine I get to make using fruit from this vineyard for Naked Wines, and the launch of the new wine brand Our Lady of Guadalupe Pinot Noir and Chardonnay.

This week we welcome Richard Bruno from Vinum Cellars. Richard pursued his interest in wine by going into the restaurant business in 1985. Working with Master Sommelier Larry Stone at Rubicon Restaurant in San Francisco as a waiter and bartender gave him the opportunity to taste rare and exciting wines from around the world; he also learned a lot about making the right decisions. It almost seems that Richard and Brian lived parallel lives for a while and most likely at least drank in the same places. But with plans to become a winemaker, Richard then UC Davis to learn Viticulture & Enology in 1994. While at Davis Richard met Chris Condos, where they bonded over their love of Chenin Blanc and other obscure grape varietals. They wanted to do things differently so in 1997 they started Vinum Cellars on credit cards and the help of friends & family. Richard also worked for various wineries from Bonny Doon Vineyard in Santa Cruz to Rosenblum in Alameda, Alexander Valley  Vineyards in Sonoma and Folie a Deux in the Napa Valley.

This episode features the return of Ben Matthews, who was a part of Episode 83 in 2018, and went on to found Terratorium, which is the focal point of conversation for this episode. Ben has been a long-time podcast listener and he and I met when he came out to Napa for the Deep Winemaking (wine camp) in 2017. A year later Ben came back to Napa to work harvest with me at Seavey Vineyard. Upon returning to Cincinnati and founding Terratorium Ben brought me into the business to help with vineyards and winemaking. 2021 was our first year of full production and the complicated path of producing our Riesling felt like a story we could share on the podcast. Our conversation covers Ben's telling of building Terratorium, the desire to make a Riesling, Tondre Grapefield in Santa Lucia Highlands, and the many obstacles and discussions we had in order to create our desired style of Riesling. We talk through every step of the winemaking, including all of the chemistries, during this discussion.

Greg Brewer - Brewer-Clifton, Datom, and Ex Post facto This episode features Greg Brewer, founder and winemaker at Brewer-Clifton, which is a winery in Santa Barbara producing Pinot Noir and Chardonnay. Our conversation runs the gamut from Greg's background, his experience working with grapes from Santa Rita Hills, harvest and processing logistics, my jealousy for Santa Rita's huge picking window, DIAM corks, Greg's stainless bin fermentors, his philosophy in sourcing a block for vineyard designated wines before planting vines, how little analytical data plays into his winemaking, the stainless Chardonnay brand Diatom, and Syrah for Ex Post Facto. Brewer-Clifton - Santa Rita Hills Diatom Chardonnay - Santa Barbara County Ex Post Facto - Santa Barbara County   This podcast is sponsored by Flextank For nearly 20 years, winemakers in the United States and Europe have used Flextanks to make world-class wines. Flextanks have many uses in a winery including the maturation of wines. They breathe like a barrel with precise and consistent linear micro-oxygenation to your wines. The Flextank system uses its proprietary Flexstaves line of staves which are sourced from premier French and American cooperages to age both red and white wines. Today's technologies are playing a bigger and bigger role in wineries these days. Flextanks have a long track record of replacing traditional wood oak barrels with a revolutionary breathable polymer that is scientifically engineered to achieve Oxygen Transfer Rates similar to your choice of either a 2-year or neutral barrel. Independent scientific studies and trials have validated this technology. Unlike a barrel, however, the molecules you want to retain- like ethanol and water- do not escape the Flextank wall, which means these tanks do not lose the Angel's share as with barrels…this means less topping is needed. Not only do Flextanks breathe like a barrel, but they are also unbelievably simple to clean- reducing water and labor costs- and are designed in a variety of sizes and profiles to make more efficient space use in any cellar. Flextanks are built here in the United States and come with a free lifetime warranty. To learn more about how you can modernize your winery and lower your barreling costs, simply go to Flextank.com. Discover how the Flextank system with Flexstaves is today's new way to make award-winning wines.   Check out the Fundamentals of Winemaking Made Easy video course   The Inside Winemaking Podcast on iTunes Now on Spotify And Stitcher Radio Too
