The Bordeaux wine region is located in the southwest of France, with the city of Bordeaux as its business center. The success of Bordeaux are its geological foundation of limestone with a lot of calcium, the soil is composed of Gravel (left bank), sandy stone and clay (right bank) and the affluence of the Gironde river and its tributaries, the Garonne and the Dordogne rivers bringing with their waters an Oceanic climate. These rivers define the areas where Bordeaux is made:
- The Right Bank: is located right of the Dordogne river close to the city of Libourne. The main grape here is Merlot and the most famous communes are St. Emilion and Pomerol.
- Entre-Deux-Mers: between two seas (meaning the rivers).
- The Left Bank: located on the left of the Garonne river and south of Bordeaux can be divided into 2 sub-regions: Graves and Medoc, the main grape is Cabernet Sauvignon and the most famous communes that produce First Growth Chateaux from the 1855 Classification are: Margaux, Paulliac, St. Estephe, St. Julien, Haut-Medoc and Pessac-Leognan the latter producing some quality Sauvignon Blanc blended with Semillon. South of Pessac-Leognan is Sauternes, famous for the botrytise wines made with Semillon, Sauvignon Blanc and Muscatelle grapes.
- Bordeaux used to be called Claret from the British.
