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 Ausone is one of the prestigious few Saint-Emilion producers with Premier Grand Cru Classe A status. It is relatively small compared to other top rated Bordeaux Chateaux, and its 7-hectare (17-acre) vineyard is planted almost entirely to Cabernet Franc and Merlot. A small amount of Cabernet Sauvignon appears in its second wine, Chapelle d'Ausone.
