Bordeaux Blend
In Bordeaux all great wines are blends of grapes. In some very rare cases a wine is a cepage: some vintages of Petrus are 100% Merlot. The typical Bordeaux grapes are Cabernet Sauvignon, Merlot, Cabernet Franc, Petit Verdot and Malbec. Blends are made from these grapes, sometimes even Carmenere is included.
Left bank blends are dominated by Cabernet sauvignon, right bank blends are dominated by Merlot.
White wines from Bordeaux are also blends in most cases, made from Sauvignon Blanc and Semillon and occasionally from Muscadelle and Sauvignon Gris.
