Chateau Margaux is one of Bordeaux's most famous wine estates, located just east of Margaux itself in the Medoc. Along with Lafite, Latour and Haut-Brion, it was rated as a first growth in the original 1855 Bordeaux Classification of the Medoc. There are also 12 hectares (30 acres) of Sauvignon Blanc to make Margaux's white offering, Pavillon Blanc, which must be sold as Bordeaux AOP, not Margaux. The red wines are fermented in a mix of traditional wooden and stainless steel vats; the grand vin sees between 18 and 26 months aging in new oak barrels.
