Côtes de Gascogne comprises about 11,700 hectares (28,911 acres) of vineyards that give an annual production of about 800,000 hectoliters of wine. The terroir enjoys an oceanic climate with mild, humid winters and hot but often stormy summers.
In Southwest France, where most wine produced is red, Côtes de Gascogne is a rare case where white wine dominates (90%). The white grapes grown here are Colombard, Ugni Blanc, Petit Manseng, Sauvignon Blanc, Sémillon, Chardonnay, and Gros Manseng; the red and rosé wines are made from Merlot, Cabernet Sauvignon, Cabernet Franc, and Tannat. Some of the best wines produced here today are from Domaine du Mage, Domaine Uby, and Domaine du Tariquet.
