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. [00:02:58] Until next time. This is sustainable wine growing with the Vineyard team.
