Château Rauzan-Gassies is a wine estate in the Margaux appellation of Bordeaux. It was classified as a second growth in the 1855 Classification of the Médoc and Graves, and like many wines in the appellation is Cabernet Sauvignon-dominant.The 28-hectare (70-acre) vineyard is located on gravelly soils which are typical to the area. Cabernet Sauvignon makes up around two thirds of plantings, with Merlot and a tiny amounts of Cabernet Franc and Petit Verdot making up the rest. Wines are vinified in modern stainless steel vats, with alcoholic and malolactic fermentations happening at the same time. Château Rauzan-Gassies typically spends a year in oak barrels, around a quarter of which are new. In the 18th Century, the estate was a part of the vast Rauzan estate which by 1855 had been split into châteaux Rauzan-Gassies, Rauzan-Ségla, Desmirail and Marquis de Terme. Since 1945, Rauzan-Gassies has been owned by the Quié family, who also own Bel Orme and Croizet-Bages.
