Château Margaux is located in the commune of the same name in the Haut-Médoc region and is one of the most famous wine estates in Bordeaux. Along with Lafite, Latour, and Haut-Brion, it is one of the four estates awarded the Premier Cru (1st Growth) category during the original Bordeaux Médoc classification of 1855.

Margaux is generally considered the most elegant of the 1st Growths and is consistently among the most expensive wines in the world. The dominant blend of Cabernet Sauvignon is complemented by a small amount of Merlot, Petit Verdot, and Cabernet Franc.

The vineyard at Château Margaux has a complex combination of soils unique to this area. They consist of chalky clay beneath a top layer of coarse and fine gravel, which is very well-suited for Cabernet Sauvignon.
