- the largest wine-producing region of France, taking its name from an important city and port and accounting for one quarter of all wine produced in appellations within France. The region produces a very wide range of styles and qualities of wine from ordinary Bordeaux AOC wines to the great crus classés; both red and white wines are produced, but the red wines predominate. The red wines from the area are mostly produced from Cabernet Sauvignon, Merlot, Cabernet Franc, Malbec and Petit Verdot grape varieties, while the white wines are produced from Sémillon, Sauvignon Blanc and Muscadelle grape varieties. The region is divided by the Dordogne river to produce two distinct areas, the right bank (with regions such as Saint-Émilion and Pomerol, growing more Merlot grapes) and the left bank. The best red wines tend to be produced in the north of the region, towards the Médoc and in graves, Pomerol and Saint-Émilion.
