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 Montrose is a leading estate of the Saint-Estephe¨phe commune of the Medoc region in Bordeaux. It was ranked as a second growth in the 1855 Bordeaux Classification, and is regarded as one of the very best properties at that level. The 95-hectare (235-acre) vineyard exists, unusually for modern Bordeaux, as one single entity. It is sited on an exposed site of deep, coarse gravels with sand and a little clay, overlooking the Gironde. The immediate proximity of the water has a moderating effect on both frost and summer heat, and the pebbles in the soil retain daytime warmth into the evening, aiding ripening. The estate is situated around a mile from Cos d'Estournel and the border with Pauillac. The vineyard is planted to a range of the classic Bordeaux varieties: 60 percent Cabernet Sauvignon, 32 percent Merlot, 6 percent Cabernet Franc and 2 percent Petit Verdot.
