Château Montrose is a winery in the Saint-Estèphe appellation of the Bordeaux region of France. The wine produced here was classified as one of fourteen Deuxièmes Crus (Second Growths) in the original Bordeaux Wine Official Classification of 1855.
Chateau Grand Corbin is a Grand Cru Classe wine producer located on the northwestern part of the Saint Emilion plateau. The estate was established in 1852 and produces a grand vin from Merlot, Cabernet Franc and Cabernet Sauvignon, and a second wine labeled Les Charmes de Grand Corbin from the same grape varieties. The estate has been owned by Groupe SMABTP, owners of numerous Bordeaux chateaux including Chateau Cantemerle in the Haut Medoc and Chateau Le Jurat in Saint Emilion, since 2010. In 2012, the group's adjacent estate, Chateau Haut Corbin, was awarded classed-growth status and the two Corbin estates were combined under one label.
