This episode features Frederick Ammons, Winegrower for Rudd Estate in the Napa Valley. Our conversation covers Frederick’s education in Bordeaux, his early jobs in California, his stint at Seavey Vineyard, the building of The Napa Valley Reserve where he made wine for nine years, and his current position at Rudd Wines. We spend the majority of our time discussing philosophical and practical viticulture touching upon organic and biodynamic practices. The central role of robust ecology and biological diversity both in vineyard soils and wine fermentation is a core theme that weaves throughout all of Frederick’s work in the vineyard and in the winery.
