Matt Killman - Walloon Lake Winery, Michigan
I have a great episode for you with Matt Killman of Walloon Lake Winery in Michigan.This week we announced the open call for producers to pour wines (or send wines to be poured) at the 2027 Embracing Hybrid Grapes conference, and I fielded a couple questions in the comments that turned out to be relevant to this episode and the next episode I’ll be releasing… both featuring growers of hybrid grape varieties in northern and eastern US states. Embracing Hybrid Grapes will be held February 21-22, 2027 at UC Davis Conference Center and Donkey & Goat Winery. The first day will feature keynotes, panels, and presentations related to the way that hybrid grapes make, not just a sustainable, but a regenerative wine business possible, even or especially in places like California. What’s unique about California is how little work has been done to develop bespoke grapes for the largest winegrowing region in North America. What I’ve come to realize is that this is merely the result of economics: it still can make economic sense to grow the high-input, conventional vinifera varieties in California. This is because in most regions, in most vintages historically, the cost to grow these old varieties doesn’t exceed what you have to charge for the wines to be profitable, and because we have trained consumers on these old varieties as if they are brands of quality. The reality of the word “chardonnay” on a bottle is that it mostly meaningless in terms of the flavors and quality you will find when you drink it, but we’ve trained wine drinkers to believe that it means something important. Varietal names, pinot noir, chardonnay, cabernet, sauvignon blanc, etc are brands in the US that convey some promise of status experience, and this, coupled with the economically conducive climate for these vinifera varieties, continues to make it economically viable to plant monocultures of these grapes. But both of these conditions are being tested and pushed to their limits with climate change and generational change. And while there are less than a handful of growers working with less than 20 acres of hybrid wine grapes out of the over 400,000 acres of winegrapes in California, every country in Europe increases their hybrid acreage every year, and every country has at least one if not multiple institutional breeding programs that have been releasing new, resistant, low-input wine grape varieties for decades. To me, this is the huge opportunity of California: an untapped market with huge resources and a reputation for progressive innovation is currently one of the most conservative and backward looking when it comes to our wine culture. But California is going to have to make a decision: will it move forward with the rest of the wine world in relevance and innovation? Or will it attempt to become an archive and museum for old varieties? I see value in both, to some extent, as long as being a museum doesn’t imply destroying ecosystems to grow maladapted varieties. And California can do both… this doesn’t have to be an either-or proposition. Right now, however, there is zero movement on the side of moving forward with ecological innovation and adapting our wine cultures for the new world.So… that’s why we’re doing Embracing Hybrid Grapes in California again this February 21st and 22nd. EmbracingHybridGrapes.com is the website, and tickets go on sale November 16th, next week!And getting back to that open call for submissions of wines for the tasting day, we have two requirements: 1) The wines must be 90-100% made of hybrid grapes, 2) and the wines must have been produces with zero herbicides. When we posted these requirements, someone asked: why only zero herbicides, why not require the wines be farmed organically, with zero chemical fungicides and insecticides too?This is an important question, and it is extremely relevant to this episode and the next one. And here’s the answer:When a grower eliminates herbicide, and we are mainly talking about synthetic herbicides, when these get eliminated, they most often aren’t replaced with other organic herbicides…. Though some growers may wish they could be. When herbicides are eliminated, they are usually replaced with mechanical options like mowing, weed whacking, and tilling, and sometimes fire, or design and management changes and mindset changes.This can also be the case with fungicide to some extent, but the reality is that you can’t eliminate fungicide in many wine growing regions, and the regions with the highest fungal pressure are also where most hybrids are planted. You can reduce fungicide applications with hybrids, sometimes enormously. You can often have success with organic fungicides with hybrids. But fungicides don’t go away. And depending on the varieties grown, and the extreme fungal pressures of growing them in places like Michigan or New York, the locations of this and the next episode, using only organic options may require you to spray significantly more often and at the exact times when it is worst to drive a spray rig over the soil: when the soil is wet and soft from the rain that is the reason you need to spray.Insecticides are similar. You can refrain from using insecticides most years in most wine regions. And there are many ways of increasing biodiversity and habitat to allow for a good predator and prey dynamic in your vineyard that keeps parasitic insects from becoming a problem. But sometimes you’ll get an infestation of Pierce’s Disease-carrying sharpshooters, or canopy destroying Japanese beetles, or grape berry moth, or new species that don’t have predators like the spotted lantern fly… and then you have a choice of either losing a significant part of your vintage or even your vineyard, or spraying something… and whether you spray conventional pesticides or organic pesticides, neither are soft options.Yes, there are a few, brave people who grow grapes organically in places like Virginia, New York, and Michigan, and every other state and region. It is possible, and I greatly admire these folks, and I’m growing by strict, better than organic guidelines on the Wineforest Farm in New York myself. But I think even these organic growers would tell you that, yes, it works for them, with their grapes, on their site, with their management… so far at least… but they probably wouldn’t say you can apply that to all sites, contexts, management, and grapes… even hybrid grapes. And some who are growing vinifera organically in these contexts may admit that they spray some organic fungicide or biological every five days or more some years. And we know that despite our best efforts we are taking a risk. It is our goal and aspiration always to be organic or better, yes. But we know that there may come a vintage where that risk results in a potential catastrophic loss, at which point we will have to make the decision of whether to absorb that loss and keep our prohibition against all pesticides and systemic fungicides… or spray something once or twice.But that isn’t true of herbicides. There are many non-chemical alternatives to herbicides. No catastrophic loss will result from the plants that grow under vines. And some design and management and mindset changes can virtually eliminate most serious problems that result from under vine plants.So we have a zero tolerance policy towards herbicides in the wine at Embracing Hybrid Grapes, and a more nuanced perspective on fungicides and insecticides. And while part of the “Beyond” of Beyond Organic Wine is related to exceeding organic standards in our approach to wine, the other part of “Beyond” is that nuance. And that nuance comes from my perspective not being guided by what is most organic, but by what is most ecological. While many people who farm organically have larger ecological values that guide their organic viticulture, “Organic” by definition is a pretty narrow set of standards that are mostly focused on prohibitions of conventional pesticides. And while this again is a gre… This is a public episode. If you'd like to discuss this with other subscribers or get access to bonus episodes, visit beyondorganicwine.substack.com/subscribe
