Cos Labory

Grand Cru Classé en 1855
Michel Reybier
In 2023, Michel Reybier and his family open a new chapter of the history of Château Cos Labory, classified a Fifth Growth in 1855, in Saint-Estèphe.

With a focus on heritage conservation, this acquisition is a tribute to its founder, Louis Gaspard d’Estournel, who first acquired it in 1847.

Sitting upon the hill of Cos, the terroir of Cos Labory is situated on its plateau of deep gravel, with its clay and limestone base, benefits from the nearby Gironde estuary and the influence of the Atlantic Ocean temper extreme weather conditions.

The 35 hectares of vines have an average age of 38. Half of them consist of Cabernet Sauvignon, a third of Merlot and a small percentage of Cabernet Franc and Petit Verdot.

Benefiting from savoir-faire acquired at Cos d’Estournel, the Cos Labory team seeks to bring the estate’s terroir to its purest form of expression.
