Henry-Frédéric Roch, the late co-director of Domaine de la Romanée-Conti and nephew of Lalou Bize-Leroy, established Prieuré Roch in 1988. They practice organic and biodynamic farming, 100% whole cluster fermentation, and next-to-zero sulfur additions. The wines are extremely spicy and elegant, with a beef bouillon note I find to be the house style's real calling card. These have become a gold standard in the non-sulfur category.
