Château Montrose, classified 2nd Grand Cru in 1855 in Saint Estèphe, is both one of the youngest and most famous Grand Crus of the Médoc. Its 95-hectare vineyard, in a single block around the château, stretches over a hillside of deep gravel mixed with sand on a clay-marl subsoil, right down to the Gironde. The river provides a temperate microclimate, favourable to cultivation. Château Montrose is among the most innovative in terms of research to limit its impact on the environment.
