Arguably the best known of French wine-growing areas, and possibly the best known wine area in the world, Bordeaux has 117,500 hectares under vine. It produces red and white wines, together with rose and clairet (a kind of robust rose), plus a sparkling wine known as Cremant de Bordeaux. Main grape varieties for reds are Merlot (main variety of right bank), Cabernet Sauvignon (main variety of left bank), Cabernet franc, and small quanitities of petit verdot and malbec. The main white varieties are semillon, sauvignon blanc, muscadelle with very small quantities of the Cognac grapes, Ugni blanc and Colombard. All in all the region produces about 5,700,000 hectolitres (1 hl = 100 litres), although due difficult weather conditions, the 2013 harvest is expected to be considerably smaller (-20%?) than usual.
