Château Cos d`Estournel is named after its 19th century owner, Louis-Gaspar d'Estournel, and it was he who built the bizarre oriental edifice that is a landmark for any tourist in the Médoc. Today Cos d'Estournel is without doubt the leading estate in St-Estéphe. It is located in the south of the appellation on the border with Pauillac and its vineyards are superbly sited on a south-facing gravel ridge with a high clay content, just north of Lafite.
Cos d'Estournel is typically a blend of 60% Cabernet Sauvignon, 38% Merlot and 2% Cabernet Franc - do not be fooled by the relatively high Merlot content, as these are full-bodied, dark, brooding tannic wines when young which develop a complexity and intensity that can rival many top growths from Pauillac.
In 1998 the Prats family sold Cos d'Estournel to The Tailan Group. Cos d'Estournel is classified as a 2ème Cru Classé.
