My guest for this episode is Caine Thompson, head of sustainability for O’Neill Vintners. Caine has initiated and oversees the largest side-by-side trial of regenerative organic viticulture in the world at Robert Hall Winery, one of O’Neill Vintners flagship brands in Paso Robles. Going into it’s 5th year in 2025, this regenerative organic viticulture trial is already providing data that show that regenerative organic viticulture, in Paso Robles, provides, at minimum, economic & wine quality parity with conventional agriculture while improving soil and vine health, carbon and water storage, and benefitting multiple other elements of the ecosystem and socio-cultural context of the winery. O’Neill has already converted the rest of Robert Hall’s estate vineyards to regenerative organic viticulture after seeing the results from just the first years of the trial.

I often use this podcast to bring attention to smaller producers doing great work who might otherwise not get the same media coverage that large brands get. And I do think that’s important. But an ecological approach to wine is not a niche obsession. It’s what needs to become the dominant culture. So I think it is also important to applaud the genuine commitments to ecological alignment by larger companies. With many other beverage brands under its control, O’Neill is the kind of company that can begin to set a larger trend and cause real change to happen. There is a lot of heart behind this story, thanks to Caine and the others he works with. Prepare yourself to hear something both inspiring and hopeful for a change.
