Château Cos Labory sits in Saint-Estèphe, the northernmost appellation of the Médoc, where gravelly soils and a maritime climate shape wines of structure and depth. The estate produces a Grand Cru Classé blend anchored in Cabernet Sauvignon, Cabernet Franc, and Merlot—a composition that reflects the region's signature architecture of power tempered by elegance. Le Saint-Estèphe de Cos Labory, built from Petit Verdot, Cabernet Sauvignon, and Merlot, demonstrates the winery's command of the appellation's darker, more muscular expression. A secondary offering, Charme de Cos Labory, rounds out the portfolio with a blend of Malbec, Cabernet Sauvignon, Cabernet Franc, and Merlot. The wines have been assessed by Decanter, Wine Enthusiast, Falstaff, Wine Spectator, and Wine Advocate. Saint-Estèphe demands patience; these are wines built for the cellar, their tannins resolving into complexity over time.
