With more than 7,000 chateaux, France’s Bordeaux region is the most important wine producing region in the world. As well as being the basis for Cabernet Sauvignon and Merlot-based wines everywhere, Bordeaux wines are acknowledged to be among the world’s best reds—according to experts and amateurs alike.

The wine region of Bordeaux is comprised of many smaller areas and encompasses both banks of the Gironde estuary in southwest France, as well as the land bordering the Garonne and Dordogne Rivers, which split off from the Gironde in the southern Medoc area. Generally, Bordeaux's best red wines are from seven major (and well-known) appellations: Pauillac, Saint-Estephe, Saint-Julien, and Margaux in the greater Medoc region, Graves to the south of the city of Bordeaux—in the region’s center, and Saint-Emilion and Pomerol toward the east. The large Graves region, as well as being the birthplace of claret, is home to many of the best dry whites. Premium sweet wines are made in Sauternes and Barsac, which are also within the Graves appellation but toward the south.
