Château Brisson produces wines from Bordeaux's Côtes de Castillon appellation, a region known for structured reds built on Merlot and Cabernet Sauvignon. The winery's portfolio centers on two flagship expressions: Le Second Côtes de Castillon, a blend of Merlot, Cabernet Franc, and Cabernet Sauvignon, and Castillon Côtes de Bordeaux, which pairs Cabernet Sauvignon with Merlot. Both wines have been assessed by Wine Enthusiast and Wine Spectator. The Côtes de Castillon terroir—situated on the right bank of the Dordogne—yields wines with the mineral precision and dark fruit character typical of the appellation, where Merlot provides richness and Cabernet varieties add backbone and aging potential.
