Château Cos d’Estournel is a winery in the Saint-Estèphe appellation. The wine produced here was classified as one of the fifteen Deuxièmes Crus (Second Growths) in the original Bordeaux Wine Official Classification of 1855.
Château Cos d’Estournel produces the eponymous grand vin, the second wine Les Pagodes de Cos from the estate’s younger vines since 1994, as well as the Château Marbuzet from fruit of nearby plots. The property is adjacent to Château Lafite-Rothschild in the neighboring commune of Pauillac.
From a 100 hectare estate, the vineyard area extends 70 hectares, and divided into 30 parcels. The annual production is typically 32,000 cases.
