In the old Gascon language, the word ‘Cos’ means ‘The Hill of Pebbles’. Appropriately named, Château Cos d’Estournel is situated on the banks of the Gironde River between Pauillac and St. Estèphe, where the property is clearly defined by the hill of Cos, reaching to a height of almost 65 feet. It is today owned by Michel Reybier, and continues to be managed by a member of the Prats family under the direction of Jean-Guillaume Prats. This renowned property produced distinguished wines since the early 1800s to the present day.
