Château Falfas produces wines from Côtes de Bourg, a compact appellation on the right bank of the Gironde estuary in Bordeaux. The region's clay and limestone soils yield structured red blends anchored in Cabernet Sauvignon and Merlot, often with supporting Cabernet Franc and Malbec. Le Chevalier Côtes de Bourg, the winery's flagship, marries these varieties into a wine that has drawn assessment from Wine Advocate, Decanter, and Wine Spectator. The estate's core offering, Côtes de Bourg, follows the same varietal framework, reflecting the appellation's character: wines with backbone and aging potential, built for the table rather than the cellar door.
