Caine Thompson and the ‘world’s largest regen organic viticultural trial’

Caine Thompson, trustee of the RVF and MD of Robert Hall Winery and head of sustainability for O’Neill Vintners, interviewed by Adam Huss of the Beyond Organic Wine podcast.

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.
