Most of the world’s wine grapes, like Chardonnay, Merlot, and Sauvignon Blanc, come from Vitis vinifera, a species prized for fruit quality but highly vulnerable to cold, pests, and disease. Assistant Professor Soon Li Teh of the University of Minnesota is developing new cold-hardy cultivars by combining traditional breeding with DNA technology—essentially 23andMe for grapes. His work taps into the resilience of native American species to improve winter survival and disease resistance. But it’s no quick fix: the process from initial cross to cultivar release takes 18 to 25 years.

Can hybrid grapes revolutionize the wine world? Adam Huss — Host of the Beyond Organic podcast and Co-owner of Centralas Cellars breaks down what a hybrid truly is, explaining how traditional breeding — and nature itself — has long crossed grape species. With over 70 grape species worldwide, today's modern hybrids are the result of generations of crossing, backcrossing, and innovation. We explore the impact of WWII on agriculture, France’s ban on hybrids in appellation wines, and why developing new hybrids is critical for disease resistance, flavor discovery, and more sustainable farming. Plus, Adam shares insights into trialing the “married vine” system — a potential game-changer for soil health, pest management, and flavor expression.

He is the host of the Beyond Organic Podcast and also co-owner of Centralis Winery in Los Angeles, California. And today we're gonna talk about hybrid grape varieties. Welcome to the podcast, Adam. [00:02:11] Adam Huss: Thanks, Craig. I really appreciate it. Thanks for having me. [00:02:17] Craig Macmillan: So let's just start with the basics. What are hybrid grape varieties? [00:02:22] Adam Huss: I should also say I'm a fan of your podcast as well, so it's really fun to be here. [00:02:26] Craig Macmillan: Thank you. Thank you. [00:02:28] Adam Huss: Been listening for a while. So hybrids, I mean, it's really simple. It's funny, I see stuff on Instagram sometimes where people just are so misinformed and they think that, you know, hybrid means like GMO or something like that. [00:02:41] A hybrid simply is just, you take pollen from grape X, you put it on flowers from grape y, and if those two grapes are from different species, you have a hybrid. If they're from the same species, you just have a cross, and this is something that has been part of traditional breeding since forever. It's also what happens naturally in the wild. [00:03:00] Or I hate, I actually just use two words I try not to use at all, which is like natural and wild, but in forests and streams forests and backyards without human intervention, these pollen get exchanged by wind and everything else and have led to, you know, some of the more. Old popular varieties of grapes that are, considered hybrids that we know of now, like Norton and Isabella and Kaaba. [00:03:23] Nobody actually crossed them. They just happened. So yeah, that's, that's a hybrid. It's very simple. [00:03:29] Craig Macmillan: That's what they are, what aren't they and what are some of the myths surrounding them? [00:03:33] Adam Huss: yeah, great question. You can't generalize about hybrids. Generally speaking. So that's really important thing for people to wrap their heads around, which is because. You know, we'll get into this, but so much, so many hybrids are, and just hybrids in general, are wrapped up in prejudice because we live in this sort of viniferous centric wine world. [00:03:56] You know, , those of us who are in wine, but there, you just can't generalize. The qualities of hybrids are just like humans. Like it depends on what your parents are. You know, you, you get different things every time you mix 'em up and you're not like your brother or sister. If you have a sibling, you know you're gonna be different from them even though you have the same parents. [00:04:13] So that's the same thing happens with grapes. There's genetic diversity and mutation happens and. For hybrids, , the possibilities, the potentials are literally infinite. It's pretty incredible to know that possibility exists. There are over 70 species of grapes on earth besides vitus vara, and if you cross any of those two varieties, yeah, you'll get a genetic cross that's 50 50 of, of two different species. [00:04:40] But that. Within that you could do that cross again and get a different variety of grape, even with the same cross. So it's just amazing. [00:04:51] The modern hybrids that are now out there are. Often multi-species crosses and have been crossed. Generationally again and again and back crossed and recrossed. And so, you know, I was just looking at a hybrid grape that had five species of grapes in its family tree. I mean, there are family trees that would make the royals blush, honestly, in some of these hybrids. [00:05:11] So it's not, it's not something that is just, can be just said. You can say one thing about it or that. And, and the idea of hybridizing doesn't imply anything at all, really, like it is just this process that happens that we've been doing for a long time. This might be a good thing to dispel some of the prejudices. [00:05:34] You know, something like the word foxy often gets thrown around when we start talking about hybrids. I did a whole podcast about this what's really interesting, I just brought this word up to a, a young couple here in LA who are growing grapes and they, they had no idea what I was talking about. [00:05:49] So that's kind of encouraging. Like in, in the younger generations, these prejudices and some of these words that we inherited from the last century , are dying out truly. Which is great, but it still persists and you still hear it a lot and. If anybody goes online and researches some of these grapes, so much of the information available online is actually still misinformation and prejudiced because it comes from this vinifirous centric culture. [00:06:15] And so it's really important for people to understand that like foxy is not what it sounds like. It sounds like it would be this animalistic, musky, maybe scent gland tinged aroma, flavor thing, but. If you taste the grapes that are known as foxy and you go, you know, start researching this by tasting, you'll find that it's actually kind of delicious. [00:06:37] It's usually fruity and you know, candy like strawberry raspberry flavors. And for those of us in the US. It's often something we associate with Grapiness because of Welchs. And the flavors of Welchs, which come from the Concord grape, which is a Foxy grape, are these grapey flavors that we grew up with. [00:06:57] This sense of like grape candy and stuff like that. And that's a lot of times what you find in these, but again, it depends a lot on. The level of the compounds that are in that specific hybrid. Again, you can't, you can't generalize. And just like with anything, if you mix different compounds together, you'll get these nuances and you might have some of that flavor or aroma, but it'll be blended with other things. [00:07:17] And so it takes on new characteristics. So it's way more complex than just thinking like a. All grapes that are hybridized are foxy. That's absolutely not true. Or that foxy is this monolithic thing or that foxy is bad. None of those are true. And then really the other thing to realize is in. Grapes in the native North American varieties of species of grapes. [00:07:41] There's really only one that has been used traditionally in grape breeding and hybridization that has these flavors. And that's Vitus labrusca. It just happened to be used quite a bit because it's endemic to the East coast where a lot of the Europeans who started all this breeding were living and, and it was, you know, very

[00:00:00] Beth Vukmanic: Training season is fast approaching. It's time to get your hospitality staff prepared to welcome a range of guests from experienced enthusiasts to first timers. [00:00:10] Welcome to Marketing Tip Monday. With SIP Certified. We know that your customers are looking for wines labeled as sustainable. While our longer form episodes help you learn about the latest science and research for the wine industry, these twice monthly micro podcasts will help you show your dedication to sustainable wine growing. [00:00:29] Most people rarely consider the complex agricultural processes behind their favorite products. Use this opportunity to offer something truly unique insight into what makes your wine sustainable. [00:00:42] Start by covering the basics of what sustainability is while you get to know your guest. Are they familiar with agriculture? Do they know that there is a relationship between the farm and the larger ecosystem? [00:00:53] Sustainability means meeting the needs of today while ensuring that future generations successfully meet theirs. We do this by caring for the three Ps. People, planet, and prosperity [00:01:06] people includes community involvement, charitable donations, continuing education and safety programs. [00:01:12] Planet includes habitat conservation plans, integrated pest management, cover crops, and responsible irrigation [00:01:20] prosperity includes sales and marketing plans, budgets, succession plans, and inventory and production records. [00:01:27] If you're SIP certified, you could explain why your brand is a part of a third party program. Specifically, SIP certified is a certification for sustainable wine growers and winemakers. It uses independent third party auditors to verify the brand's practices and records to ensure that they're meeting strict standards. [00:01:47] Now it's time to show how sustainability is specifically meaningful to your brand. This will help your guests understand what issues are important to you and what you're doing about them. [00:01:57] Follow these three simple steps. [00:01:59] One, download the sustainable story worksheet linked in the show notes. [00:02:04] Two, talk with your vineyard manager, winemaker or general manager to get an example of each of the seven values, which include social responsibility. Water management, safe pest management, energy efficiency, habitat business, and always evolving. [00:02:20] For example, attracting gopher hunting barn owls with barn owl boxes in the vineyard is a great example of safe pest management. And three, pick one value to focus on each month to share a fun story with your guests [00:02:35] if you want to get inspired. We've been collecting sustainable stories from our SIP certified members for the last three years. You can find all of those linked in the show notes. [00:02:45] And if you want to go deeper than the sustainable story worksheet, we have a great free online course that will help you learn what sustainability means in the wine industry and how to tell your own unique sustainable story.

He is a volunteer with Pacific Wildlife care in SLO County, California. And today we're gonna talk about barn owls. Thanks for being on the podcast, Bob. [00:01:48] Bob Peak: Thank you very much Craig, and I want to thank you and the Niner Wine Estates for this invitation. I think that this going to be very informative and quite fascinating actually. [00:02:00] Craig Macmillan: Yeah, so I'll give you a little bit of background on that. I met Bob, when he came out to Niner Wine estates, looking for clutches, looking for looking for outlets, and we learned all kinds of fascinating things. And I was like, I have got to talk to this guy on the podcast 'cause there's so much information and interesting things about barn owls that I didn't know, until a couple months ago. [00:02:23] But why don't we start with you telling us a little bit about, pacific wildlife Care. [00:02:28] Bob Peak: Yes. Pacific Wildlife Care was started 41 years ago here in the county by home rehabbers. There was no facility. People did their work in their specialty right out of their home, whether it was raccoons or opossums. We people tended to have a different skill that they were good at, and it started with very humble beginnings. [00:02:51] We finally reached a point where we could afford a facility and we went and occupied part of the PG&E power plant there in Morrow Bay. We are right next door to the Marine Mammal Center, if anyone knows where that is, and we are right now in the process of having to move as they are, also as there are plans coming up for the property. [00:03:17] We currently have had some donors step up and provide us with not only the 10 acres of land on Buckley Road in San Luis Obispo, but we are also very quickly in the process of building a brand new facility out there. [00:03:35] Craig Macmillan: That is really great. There's definitely a need for this. How did you personally become involved in wildlife rehabilitation? [00:03:43] Bob Peak: I needed something to do after I retired and I literally, I saw an ad in the Tribune, a local paper that said that they were looking for volunteers and I had had some experience with the birds of prey as a a child. I have a Native American background and they're a very important part of our culture. [00:04:04] we, we learned about them early on and the opportunity to work around people that were like-minded as far as with the animals in San Luis Bipo County was rather exciting. [00:04:18] Craig Macmillan: And so let's move on. Talk about barn owls specifically. Why is it important to encourage and protect barn owls? [00:04:24] Bob Peak: Ooh, that's a good question. barn owls are a species that really keep things in check. They're the balance to something that could get outta control very quickly. and I think we all see that, whether it's at our houses or at the wineries. And that's these, the rodents and other pests. That not only are harmful to us but they're harmful to our crops and even potential danger to us as well. [00:04:56] They are voracious eaters. They consume anywhere between six to eight voles or gophers a night. And that's each when a parent is feeding the young. That number can go up by times four. You could see that you might be 30 vols taken a night. So they do a tremendous job for the environment. And again, they, they're more of a checks and balances. [00:05:29] I think too that the more barn owls that you have in an area it means that you're basically protected. It's one of those things too where people also think the same way with the, the skunks or opossums and raccoons. They can be nuisances at times, but they serve a very good purpose in eliminating all kinds of pests, insects, and things that you don't want. [00:05:56] Craig Macmillan: What is the lifecycle of a barn owl? [00:06:00] Bob Peak: . I wrote a couple of notes down on this. The lifecycle is rather short for barn owl. The, they're cavity nesters, what happens is the, the barn owl parents make for life, they're monogamous. So they'll stick around they'll find a cavity barn or something that a box where they'll head in and lay anywhere between one and eight eggs. The incubation period is rather quick. [00:06:38] The breeding season is basically between late January and February for about six to eight weeks. , about a week and a half before the female laser eggs, she's nest bound. She's too heavy to fly. She can't even get out of the box. [00:06:53] Another thing that she does at that same time is she picks a little brood patch. On her belly to where she can remove those feathers. And once the young born, 'cause they have no feathers, she will put them right next to that skin of hers for the warmth that they're gonna need. [00:07:15] Incubation is 29 to about 34 days. Again, they could lay between one and eight eggs. And they can do that three times a year. They might just have one clutch of eight. They could have two or maybe even three if the conditions are right. [00:07:33] She'll turn these eggs every so many minutes and then it takes, oh, I would say, you know, like 29 to 34 days, [00:07:44] and then the chick to get out from the shell. The have this little hook on the end of their bill. It's an egg tooth that's on the end of their, bill. And then that will actually break the egg open and it does take a while for, it takes 12 to 36 hours for 'em to get out of that eggshell. Four to seven. [00:08:08] It'll be about four months before they'll see another. But brood, because once they leave, then they'll lay more eggs. [00:08:17] The four months will pass from the egg being laid to the young, gaining independence. That's it. And they pretty much don't receive much training from their parents. It's, they get out of the box and then they're on their own. Where a great horned owl will spend up to a year or more, even longer with their parents. [00:08:37] Craig Macmillan: Hmm. [00:08:39] Bob Peak: A freshly hatched barnells Pink mentioned that know they hatch in sequence of the way that they were laid. [00:08:46] Craig Macmillan: Oh. [00:08:46] Bob Peak: The oldest could be three weeks old when the youngest hatches. So there is a. A challenge for food with that young one because that big one's gonna be going after it. So that's right off the bat. You know, you got some you know, some things working against you. [00:09:03] The downey Plumage starts to show up about three weeks later. They tend to clutch together and for that warmth till then. And then the female again, is taking the food brought by the male. The male is doing all the hunting. And the male will bring it in. The female will grab that food and rip it apart and feed it individually to each of the babies. Very small pieces [00:09:31] about the time they're two weeks old, they can stand on their own and they can actually eat whole prey. And now that's something to see on itself, to watch these little critters take a vole or a small mouse and swallow that you think they're gonna choke. It's quite. For a parent, you kn

As biological technologies continue to advance, many growers are exploring how best to integrate them into their farming operations. Nevada Smith, Head of Marketing North America, and Robert Blundell, Research Plant Pathologist, both with Pro Farm Group, highlight the role of biological pesticides and biofertilizers in sustainable winegrowing. Biological pesticides, derived from microbial sources or natural products such as plants, fungi, bacteria, or nematodes, play a crucial role in pest management by inhibiting or delaying growth or directly causing pest mortality. Understanding which biological products to use and when to apply them within an integrated pest management system is essential for maximizing their effectiveness. Biofertilizers, which enhance plant health and resilience to abiotic stresses, are another key tool for sustainable viticulture. Nevada and Robert discuss the growing importance of these technologies in improving soil health and supporting long-term agricultural productivity.

He is Head of Marketing North America and Robert Blundell, who's a research plant pathologist, both with Pro Farm Group. Thank you for being on the podcast [00:02:15] Rob Blundell: Thank you, Craig. [00:02:16] Nevada Smith: Thank you. [00:02:18] Craig Macmillan: Today we're gonna be talking about bio pesticides and we might as well start with the the basics. What is a biological pesticide? Robert, why don't you start? [00:02:26] Rob Blundell: Yeah, that's a good question, Craig. And and you know, honestly, it's. So when I first was kind of thinking about this, it's not as simple explanation as you might think. It's a constantly kind of evolving term and depending on who you are asking, you can get a, a very different answer. And it's, it's really kind of this large umbrella term. [00:02:42] . It's kind of a microbially based product or natural product typically derived from a plant, fungi, bacteria, nematode, you know. That pretty much has the ability to inhibit or delay the growth or, you know, cause the death of a pest. [00:02:56] And you know, with the term biological pesticide, pesticide being extremely broad whether it's, you know, insect, fungi, even rodent, you know, rodent sides, things like that. So yeah, again, it's a very broad term and different, different grooves, different commodities are gonna kind of have their own explanation. [00:03:09] Even the EU has a different, I think definition versus the EPA as well. So it's an evolving, evolving term. [00:03:15] Craig Macmillan: What about you, Nevada? Do you have anything to add to that? [00:03:17] Nevada Smith: I'm kind of with Robert, it's almost like sustainability. What does that mean? It means to me, I get to keep farming every year. But I think for everyone else it might have different definitions. And I think basically the, the premise is, is it's biologically based. It's based on a living organism, something that we can repeat, regrow, and, you know, the societal part of it, bio pesticide, it means it's acting or killing or helping mitigate pest. For proform have a biologically based strategy. And so we, that's what we deliver is those type of tools. [00:03:50] Craig Macmillan: One of the major pets on grapes is powdery mildew. Around the globe. Probably the major pest overall, I would say fungal disease. I have been seeing a lot of increase in the use of bio pesticides specifically for powdery mildew, some in organic systems, some in more traditional sustainability oriented systems. [00:04:09] What kind of mechanisms are there out there in the biological world for managing powdery mildew and how does that, how do they work? Nevada, do you wanna start? [00:04:18] Nevada Smith: Yeah, so for biological pesticides, there's sort of different categories and I'll even. Even throwing some sort of organic pesticides as well into this whole mix. I think as a grower or a wine processor, you have a choice and it's like, either I'm going conventional, I'm looking to maximize my value proposition on my vineyard or my process my wines. And so one of the ways we really think about this is how do you integrate bio pesticides into the overall spray for bio mildew, like our winemaker at our place they always say, Hey, if it's more than 3% power mildew it's a no go. It's a bad day for us. And so for us to take the risk on our farm. For a biologicial pesticide, we had to have some data to really get us excited about it. [00:05:02] Overall, we wanna see performance. We need to see at least seven to 10 days. And I think that's maybe the biggest challenge a powerdy mildew issue is depending on what sort of climate and what variety of grapes you're growing is how long does it take me to get across the vineyard? [00:05:17] It's really what it comes down to. [00:05:18] And you know, maybe from a pathology point of view, Robert has some perspective. [00:05:24] Rob Blundell: The way we want to kind of think about powdery mildew is it's, you know, it's, it's always gonna be there. It's gonna be present. And biologicals, when used in the right way, can be a fantastic you know, tool in the arsenal. For, for growers or farmers against a deadly pathogen like this. [00:05:38] Growers really need to kind of consider the goal of using a biological, because there's so many different mechanisms of action of a biological, I mean, it can be live, it can be live, it can be the, you know, the spent fermentation product of a biological, which is gonna work very differently versus an actual liable organism you're gonna put in your field. [00:05:53] So kind of having a clear mindset from the, from the start is gonna be crucial to knowing. What kind of biological do you use? And also importantly, kind of when to use it as well. Because you can have drastically different outcomes based on like the time of your, you know, the time of venue production and then, and then the time of the season as well. [00:06:09] But yes yeah, ultimately there's broad, broad mechanism of actions. So if we're putting something on there live you know, you know, with something like powder mildew, this, pathogen functions because it attaches onto leaves. So we have these overwintering structures called cassia. [00:06:24] So these are basically the dormant structures that are gonna help powerdy mildew, survive. That's why it's been around for so long. That's why it's, it comes back every year. So it basically shuts down, it's fungal mycelium into these dormant hard structures. And then every year it basically reawakens around spring when we get the rainfall. [00:06:39] So we're gonna get ASCO spores. These are specialized spore structures within that kind of dormant structure. They get released out. So, you know, with the, with the weather coming in this week, that's gonna be, huge out there right now. So we're gonna get the release of those spores. [00:06:51] They're gonna land on that leaf. So really that's kind of our prime target of having protection is when they're gonna be landing and t

[00:00:00] Beth Vukmanic: Sustainable farming practices are essential to protect the environment, improve a long-term agricultural productivity and support healthy communities. [00:00:08] Welcome to Marketing Tip Monday with SIP Certified. We know that customers are looking for wines labeled as sustainable. While our longer form episodes help you learn about the latest science and research for the wine industry, these twice monthly micro podcasts will help you share your dedication to sustainable wine growing. [00:00:27] And this week's marketing tip, we're going to take a close look at three areas where regenerative farming practices make a big impact, including water management, soil health, and habitat preservation, [00:00:39] let's kick it off with water management. Water is one of agriculture's most critical resources. Sustainable farmers work carefully to both use water efficiently and protect quality. Anyone who has struggled to keep a plant alive knows that plants don't like too little or too much water and wine. Grapes are no different. [00:00:57] Regenerative farming practices incorporate moisture sensing technologies to help farmers determine irrigation needs when placed in the soil. These devices estimate how much water is available to the plant, and farmers can use this information to avoid both over and under watering their crops. [00:01:13] When it comes to rain, there's a greater impact than just irrigating the grapevines. Heavy rains can pull sediment, nutrients, and other farm inputs into neighboring water bodies. This causes imbalances in the water body ecosystem and could threaten the life within it. [00:01:28] Plant matter can remedy these issues. Roots of living plants spread underground act as a filter that holds sediment in place. Preventing it from exiting the property. Vegetation above ground slows water down as it travels and eases the impact of rain as it hits the ground. Furthering the anti erosion benefits. [00:01:46] The next time you drive past a vineyard, take a look at the plants growing in between the vine rows. Those cover crops are help protecting waterways. [00:01:55] Now let's talk about soil health. Healthy soil is the foundation for a thriving farm and a resilient ecosystem. Sustainable practices aim to keep soils rich in nutrients full of life and resistant to erosion for years to come, [00:02:08] rather than relying on guesswork. Farmers committed to sustainability conduct regular soil tests. This helps them make nutrient management plans that supply the plants with the food that they need without over applying fertilizer [00:02:22] and back to those cover crops. Healthy soils have a lot of life in them. Microbes, fungi and bacteria are key players in decomposition, helping to convert and transport nutrients that are vital to a healthy plant. [00:02:35] While cover crops are a fantastic way to enhance soil biodiversity, their benefits extend even further. They can provide refuge for beneficial insects, prevent erosion and improve water infiltration. [00:02:48] Let's talk about habitat preservation. The influence of farming extends beyond the fence line. Regenerative farmers recognize that their land is part of a larger ecosystem. Protecting natural habitats and promoting biodiversity are key components of responsible land management. Many farmers set aside areas of their property to remain wild or minimally disturbed. [00:03:09] These spaces serve as important refuges for wildlife and help preserve native plant and animal species beyond simply leaving areas undeveloped. Sustainable farmers often actively work to create and maintain habitats that encourage a diversity of species, including pollinators and beneficial insects. [00:03:28] They may also take special measures. To protect endangered species where applicable. [00:03:33] All of these regenerative practices are incorporated into the SIP Certified program.

She's Director of Grape Brokerage with Turrentine Brokerage. And also, Eddie Urman, who's Central Coast Grape Broker with Turrentine Brokerage as well. And thanks for coming back. This is part two of a, of a, of an episode here. So, I really appreciate you folks making time to come back. [00:02:00] Audra Cooper: Thank you for having us back. We're excited to join you once again. [00:02:04] Eddie Urman: Yeah, thanks for having us. [00:02:05] Craig Macmillan: So Audra, let's start with you. In our last conversation . [00:02:17] And that was kind of where we left it that then started a conversation amongst the three of us afterward. We were like, okay, there's a lot more to talk about here. So let's do it. [00:02:24] Can you give some examples of what you mean by getting ahead of changes? [00:02:30] Audra Cooper: I think it's a sound business strategy to always try and stay ahead of the curve regardless of what component of business or what industry you're in, right? It's just a, a good strategy to have and a good philosophy to have. It's really important in this industry to continue to stay relevant and in order to stay relevant, you have to stay within the trend or ahead of the trend. [00:02:51] Being behind the eight ball is, never a good thing . You need to be ahead of the curve. A good example of that is sustainable certification. And we still have these discussions on the daily and Eddie, you can talk to this too about how often we have to talk about if you're not sustainably certified, you are cutting your buyer pool, probably roughly in half, as I mentioned in the previous podcast, and you're limiting yourself. [00:03:18] And the majority of the practices, most growers are probably already doing, and they're just not going through the certification process and getting that done. And if you look back a little over a decade ago, it was something that wineries were paying, you know, 25, 50 per ton more for, they were paying a premium. [00:03:36] And then it became more of a, this is really nice to have. And so more and more growers We're doing it as a point of differentiation in their marketing. And now today it's almost a necessity. It's no longer something that's necessarily going to get you a premium price for your grapes. It's also not necessarily a point of differentiation any longer. [00:03:55] It's a need to have. [00:03:57] Craig Macmillan: Yeah, Eddie, do you have anything to add to that? [00:03:59] Eddie Urman: No, I think that's a great example. , Audra offered up. [00:04:02] Craig Macmillan: So there's, trends around that, and there's a lot of certifications now, and I agree, I think a lot of folks don't need to be afraid of whatever the certification is, because you're probably doing a lot of those things already, a lot of common practices. [00:04:13] I think that's an interesting insight that now it's kind of becoming expected or certainly a requirement for a lot of wineries. [00:04:19] Let's talk about changes in acreage. That's where we left off last time when we were talking about the difference between vineyard removals, which have been suggested, recommended, et cetera, by a number of folks in the industry as we just are in oversupply period I've heard estimates that we may have 30 to 35, 000 acres of grapes, more than we need based on current demand. [00:04:40] how accurate do you think that is? , how bad is it on the supply side? [00:04:45] Audra Cooper: Well, I think you have a couple parts to that question, right? Let's dissect that a little bit and start with, we just got back from the Unified Wine Grape Symposium in Sacramento, and of course, during the State of the Industry, Jeff Bitter gave his annual synopsis of the nursery survey that they do annually on how many vines were sold, and they do a, A lot of data work in regards to what were removals and his number that he reported over the last two years was 37, 500 acres have been removed from the state of California. [00:05:15] He believes based on their research that another 50, 000 acres need to be removed to reach the point of balance, assuming that consumption stays at its current rate or drops just a tiny bit. [00:05:29] And when we look at our information internally, now we don't do a survey like Allied does, but we're tracking a lot of information, both with our winery partners as well as our grower partners in regards to who's doing what, and our number's a little bit higher, but we also go back four years technically going back to 2022, our number for the state of California is closer to about 50, 000 acres that have been removed, and, you know, I would argue that If consumption stays flat, certainly there will need more removals, but I don't know about 50, 000 acres more. [00:06:04] That seems like an awful lot of acres that need to be removed. If his numbers are right, that would put us back to Basically global recession numbers, which would be around 500, 000 acres bearing.  [00:06:16] Craig Macmillan: right. in the Grape Crush Report, which is an annual report that's put out by, uh, California Department Of Food and Agriculture and the National Agricultural Statistics Service, there is a non bearing acres section in there, which I always find very interesting. Are we able to glean anything from that data in terms of what's been sold, what we think's gonna go back in, et cetera? [00:06:39] I want to put a timestamp on this. So this is being recorded first week of February, 2025. So the unified was in 2025. The report that's coming out is going to be for the 2024 year. [00:06:48] What can we learn from that non bearing acreage report?  [00:06:51] Audra Cooper: So there's two different reports. the acreage report will be coming out a little bit later in the year. We're going to have our crush report come out on February 10. I think you can glean two pieces of information, but both are very similar. And that is how much acreage has actually been removed and how light the crop truly was, particularly in the coastal regions for 2024. [00:07:10] And so when we look at, for example, a 23 bearing and non bearing acreage information from the state of California they're reporting 446, 000 acres of bearing wine grapes. And if you take that at, say, 7 tons an acre, that's 3. 12 million tons. And we know with certainty at 7 tons an acre, That acreage seems pretty low. [00:07:35] It doesn't seem realistic. So unfortunately, because it's a voluntary report when it comes to bearing versus non bearing acres, I do think that the state's probably about two years behind on real data trends. And so unfortunately right now, if you were to use that report as, you know, an analysis of the industry, you'd probably be a bit off. [00:07:54] Craig Macmillan: got it, got it. Are there trends in what varieties are coming out and what varieties are going back in? Because that's often been t

[00:00:00] Beth Vukmanic: A label can provide a lot of information about a wine. The next time you walk down the wine aisle, look for common terms and symbols like vintage, place of origin, percent alcohol, and even the SIP certified logo. [00:00:12] Welcome to Marketing Tip Monday with SIP Certified. We know that customers are looking for wines labeled as sustainable. While our longer form episodes help you learn about the latest science and research for the wine industry. These twice monthly micro podcasts will help you share your dedication to sustainable wine growing. [00:00:29] Many labeling requirements in the United States are defined by the Code of Federal Regulations. In this week's marketing tip, we are giving you a green wine glossary. Five common wine designations, defined, so you'll wonder no longer. [00:00:45] Number one is vegan. Not every wine fits the vegan lifestyle. During the winemaking process, small particles can cause haziness or unwanted flavor properties. Winemakers can add a fining agent that will bind to these tiny particles and make them large enough to be filtered out. Many fining agents are animal based. Egg whites, casein, and gelatin. Wine that was fined with any of these materials cannot be considered vegan. Vegan wines include those that were either fined with a non animal based agent. Like bentonite clay, or not find at all. [00:01:19] Number two is natural. There is no official or regulated definition of natural wine. That being said, most understand it as a wine that was made through a minimal intervention, no additive approach. Natural wines are fermented with native yeasts versus adding yeast. They cannot be filtered or fined, nor can winemaking additives be used, except for a small amount of sulfur pre bottling. If you are told that the wine you're drinking is natural, remember to ask what it means. [00:01:48] Number three is organic. Wine must meet several requirements in order to be labeled as an organic wine. The vineyard must be certified organic, the winemaking process must be certified organic, and the final product must contain at least 95 percent organic ingredients, no additives, and no preservatives. Please note that wine made with organic grapes are not the same as organic wines. While this definition means that a hundred percent of the grapes used were certified organic, Other ingredients in the wine do not have to be organic, but do note that they cannot be genetically engineered. Another thing to keep in mind is that organic designation varies between countries. [00:02:25] Number four is biodynamic. The biodynamic farming principle is guided by nature's rhythms and the understanding that the vineyard is a self contained ecosystem where all elements live and work together. Like organic, synthetic inputs are prohibited in biodynamic farming. But unlike any other program, the timing of biodynamic practices aligns with the lunar and celestial cycles. This is because of the belief that moon phases in planetary positions affect the flow of sap and energy in the vines, and that there is value in keeping practices in sync with these forces. Demeter International is the most recognized certification body for biodynamic wines. For a wine to bear the seal, the grapes must be grown in adherence to the biodynamic principles, and the wine must be made through certified biodynamic processes. [00:03:12] And number five is sustainable in agriculture. Sustainability means adhering to practices that protect social and environmental health while enhancing economic vitality. sustainably grown grapes are farmed similarly to organic and biodynamic grapes. All programs seek to protect human and environmental health through reducing inputs and conserving. And regenerating natural resources where sustainability differs is that it looks beyond the farm and into the business itself, including worker safety, community relationships, continuing education and accounting and budgeting, just to name a few of the areas that certification bodies like SIP certified address in the standards. Certification also extends from the vineyard and into the winery. [00:03:55] Did you know that your wine can include the SIP certified seal on the label if it's made with 85 percent SIP certified fruit, whether it is estate or purchased? Simply go to SIP certified. org to apply today. So your customers will know that your wine was made through practices that protect the people and the planet.

Managing pests like powdery mildew, downy mildew, botrytis, and sour rot can be a complex challenge. Andy Fles, Vineyard Manager at Shady Lane Cellars in Michigan, shares insights from his USDA Sustainable Ag Research Education producer grant project. The project compares two pest management approaches: a ‘soft’ pesticide program and a conventional one. Andy conducted the experiment using his on farm sprayer, providing real-world results. Despite climate variability and fluctuating pest pressures, the soft pesticide program proved effective. The project underscores the potential of using softer chemistries to manage disease while maintaining fruit quality.

[00:00:50] Andy conducted the experiment using his on farms sprayer, providing real world results. Despite climate variability and fluctuating pest pressures, the soft pesticide program proved effective. The project underscores the potential of using softer chemistries to manage disease while maintaining fruit quality. [00:01:10] If you'd like to learn more about this topic, then we hope you can join us on April 25th, 2025 for the fungicide spraying evolving strategies in Grower Insights tailgate taking place in San Luis Obispo, California. Dr. Shunping Ding of Cal Poly will share updated results from a study on the efficacy of different fungicide programs containing bio fungicides. [00:01:34] Then we will head out into the vineyard to learn about new technologies for integrated pest management and talk with farmers from different growing regions about their program. Now let's listen in.  [00:01:49] Craig Macmillan: Our guest today is Andy Fles. He is the vineyard manager at Shady Lane Cellars in Michigan. And today we're going to talk about a pretty cool little project. He's got going looking into two different pesticide programs. Thanks for being on the podcast, Andy. [00:02:03] Andrew Fles: Yeah, my pleasure, Craig. [00:02:05] Craig Macmillan: So you have a grant from the USDA sustainable agriculture research and education program. To look at what you call a soft pesticide program for your vineyard in Michigan and comparing it to what we would call a sustainable or sustainable conventional program. What do you define as a soft pesticide program? [00:02:25] Andrew Fles: Well, that's kinda just a, a term that we applied to identify it. I didn't want to use organic because I thought that there would be a good chance we would utilize things that are considered by the industry to be very soft in terms of you know, they're not a harsh chemical or a carcinogenic, a known carcinogenic compound. [00:02:49] But something, for example, like. Like horticultural grade peroxide, which goes by several different trade names. So that's just, it's hydrogen peroxide and it is a disinfectant that turns into water and oxygen. So it's pretty Soft in terms of what it does to beneficials and, and plants and, and such. [00:03:11] We utilize some of those products already in our spray program. But combined also with, we're probably 50 percent organic in terms of what we spray out. for fungicides, pesticides, insecticides. And so we're still altering in some synthetic compounds. [00:03:28] And we wanted to compare that, what we currently do, to something that was much softer, like only soft compounds. Something that could be considered a OMRI certified organic program, or, or almost, right? Like maybe there's just one or two things that are very soft, but not technically OMRI certified. [00:03:49] Craig Macmillan: Right, and I do want to , get into the weeds on that a little bit later. Cause it's a, it's an interesting, Set a program that you've got going and I have lots of questions about them. What inspired this project? [00:04:01] Andrew Fles: I think just that continued movement towards investigating what works here in the east. You know, we, of course, get more wetting events and, and wetting periods that cause more fungal issues here compared to the west coast. And so we really, you know, we have to have an eye on sustainability. Certainly at Shady Lane, we really push for that. [00:04:25] But we also need to make sure that we have a marketable crop. We need to make sure the wine quality is, is high and acceptable for our standards. And so you know, if we're talking about, you know, every year is quite different here. We can get a, like, for example, in 2024, very wet in the first half of the year, very, very dry in the second half. [00:04:51] And, and then, which was quite different from 23 and quite different from 22 and so on and so forth. so, so some years we need to kind of step in and use a synthetic product here at this key time or, you know we need to protect our, our, our wine grape quality. [00:05:07] Craig Macmillan: What are the primary pests and diseases in your area? [00:05:11] Andrew Fles: So we have issues with the usual suspects that powdery mildew, of course. That's, that's fairly, I think if you're on top of your game, that's, it's pretty controllable. Even with soft products here it's just a spray frequency and coverage issue. [00:05:27] Downy mildew is something that can be quite challenging in certain years. [00:05:31] And there's, and there's less tools in the toolbox to use for that as well. And so you gotta, you gotta be on top of that with scouting preventative, like canopy, you know, canopy management practices that deter too dense of a canopy or, or clusters that are. hidden behind several layers of leaf. [00:05:53] Those are going to cause problems for you no matter what you're spraying, synthetic or organic, right? So, so we try and utilize all those things and and then we, we can also have issues in some years with botrytis and even sour rot and tight clustered varieties. So, so we were looking at sour rot and botrytis in the, in the cluster analysis of this portion of the , project. [00:06:18] Yeah, we have some locations can struggle with grape erinium mite. That's becoming more and more prevalent here. Wasn't an issue four years ago. Not, not really up in, up in northern Michigan anyway. So that's becoming more and more of an issue. And then we always struggle with rose chafers. It's a, it's a grub that, you know, comes out for six weeks and really terrorizes the vines. [00:06:49] And for that, for that pest, we really walk the line of the economic damage threshold, right? So, so a little, you know, we're going to see rose chafers every year. Some years are better than others. And what is our acceptable damage, you know? And so, once we see the rose chafers really getting dense in number, and also, you know, munching on a few leaves is one thing, munching on the clusters and the shoot tips is another thing. [00:07:21] Craig Macmillan: That's what I was going to ask. Yeah, I'm unfamiliar with this this pest. It, skeletonizes leaves, but it also will attack flower clusters and, and grape clusters in the early stages of development. Is that right? [00:07:34] Andrew Fles: Pretty much all green tissue. Yeah, a bunch of shoot, shoot tips leaves are probably, you know, their preferred source, I think, but anything tender. And so if, if the timing is just right where the, the inflorescences are, are you know, just coming out when the, when the beetles hatch, then they can really go for those cluster tips and, and shoot tips. [00:07:59] While we're scouting for this pest, we not only do the, you know, the density numbers and annotate that, but we look at, you know, how many are actually eating leaves versus shoot tips and clusters. [00:08:13] Craig Macmillan: Interesting, interesting. What is the design of your project and what varieties are we talking about? And what kind of variables are you measuring and how are you measuring them? [00:08:25] Andrew Fles: this is a farmer grant as opposed to a research grant. , it's tailored to folks that want to do on, on farm trials. And we want to do. Something in a significant enough volume, you know, that, that some that it would apply, it would be more applicable in the real world. [00:08:45] So for example you know, at a university they might do this randomize
