The municipal appellation is the northern part of the Graves area(Bordeaux) and is named after the two most important towns. It covers 1,300 hectares of vineyards in the communes of Cadaujac, Canéjan, Gradignan, Léognan, Martillac, Mérignac, Pessac, Saint-Médard-d'Eyrans, Talence and Villeneuve-d'Ornon. Before the classification as a separate appellation in 1987, which André Lurton successfully tried to obtain, the area was called Haut-Graves. Around the town of Pessac, the Clairet was produced in the Middle Ages.
The dry white wines from Sauvignon Blanc and Sémillon are produced with barrel fermentation and oak ageing and are among the best in Bordeaux. The red wines are mainly blended from Merlot and Cabernet Sauvignon with shares of Cabernet Franc and Malbec(Cot). These are the typical grape varieties of the Rive gauche (left bank). However, the cuvées in the vineyards are very different.
