The estate's name comes from its geographical location on the hill of Cos and the name of François Labory, who was the first owner until 1845.
In 2023, Michel Reybier and his family opened 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.
Michel Reybier will « perpetuate the estate’s independence while pursuing the level of excellence made possible by this great terroir of Saint-Estèphe.
