A geographical and geological wonder, Cos d'Estournel benefits from an unparalleled combination of soils and exposures. This wealth of natural variations is fully expressed in the estate's wines, which are among the most renowned in the world. Cos d'Estournel is ideally situated in the heart of a hilly landscape in the northern Médoc. The undulating terrain of the estate served as the inspiration for its name. The "cos" comes from the word for "hill of pebbles" in the old Gascon dialect.
