Majestic, intense, full bodied and tannic, Cos dEstournel is considered the leading wine of St Estèphe. Highly tannic in its youth, over time it develops much much like the great wines of adjoining Pauillac. The wine is typically a blend of 60% Cabernet Sauvignon, 38% Merlot and 2% Cabernet Franc, consistently displaying immense power and evident breed.

With its name enclosed in a heart on the label, Chateau Calon-Ségur is a third-growth estate (3ème Cru Classé) in Saint-Estèphe. Firm and sturdy in style, Chateau Calon-Ségur is somewhat austere in its youth, possessing a prominent tannin structure that rewards extended cellaring over 10 to 20 years.
