Gascony is a wine growing region in the southwest of France. It has a mild climate with warm summers and short winters. It is here that Ugni Blanc, Folle Blanche and Colombard grapes are used to produce Armagnac. It is also the home of the Madiran Appellation d’Origine Contrôlée. These wines are required to be made up of 40-60% of the Tannat grape and are usually supplemented by Cabernet Franc, Cabernet Sauvignon and Fer.
