Château Coutelin-Merville sits in Saint-Estèphe, the northernmost appellation of Médoc, where gravelly soils and a maritime climate shape wines of structure and depth. The winery produces two principal expressions. Its Saint-Estèphe blends Merlot, Malbec, Cabernet Franc, Petit Verdot, and Cabernet Sauvignon into a wine that reflects the region's signature character—firm tannins balanced by dark fruit and mineral tension. L'Excellence du Château Coutelin-Merville Saint-Estèphe, a secondary blend of Merlot, Cabernet Franc, and Cabernet Sauvignon, offers a more accessible entry to the estate's style. Both wines have been assessed by Wine Advocate, Decanter, Wine Enthusiast, and Wine Spectator.
