A 75 km long and 5 to 15 km wide estuary (estuary) in Southwest France, It is created by confluence of the two rivers Dordogne and Garonne and then flows into the Atlantic. With a surface area of 685 km², the Gironde is the largest estuary in Europe. The Gironde begins at the tapered Bec d'Ambes peninsula, about 15 kilometers north of the city, formed by the two rivers Bordeaux, The vineyard area extends along the entire length of the left bank Médoc, which is ideally suited for viticulture due to its permeability of gravel and gravel. The best crus (layers) are those that "see the water" (bordering the Gironde), because the sunlight is reflected through the large surface of the water. By storing the heat there are very good conditions for an optimal grape ripeness. Here are the six famous community appellations of the Haut-Médoc,

In the area of the department of Charente-Maritime, which borders the department of Gironde to the north, the terrain slowly becomes flatter and viticulture disappears.
The mouth of the Gironde in the Atlantic Ocean is marked by the designated as "Pointe de Grave" headland at the community Le Verdon -sur -Mer. The entire right bank along from Dordogne and Gironde is called Rive droite (right bank), the entire left bank along Garonne and Gironde is called Rive gauche (left bank).
