Bordeaux ‘s climate is usually classified as an oceanic climate: The summers are very hot and long and the winters are mild because of the prevalence of westerly winds from the Atlantic. Bordeaux is known for making the greatest red in the world and they produce a third—or five and six millions hectoliters of wine—per year. La Gironde, the largest area, produces some of the best wines in the world. The diversity of wines of the Médoc created a broad classification in which these wines are divided: Peasant vineyards, craftsmen (architects), superior and more vintage bourgeois, ordinary bourgeois and good bourgeois vineyards.
Bordeaux is divided by two rivers: the Dordogne and La Garonne. The right bank is made up of Fronsac, Pomerol, St Emilion, Cote de Blaye, Cote de Bourg. The left bank includes St Estephe, St Julien, Loupiac, Sauterne and Haut Medoc.
