Armagnac is a type of brandy which is produced in the Armagnac region of southwestern France. It is made from grapes which are fermented and then distilled. Armagnac is aged in oak barrels for a minimum of three years and up to fifty years. It is a strong, robust spirit with a distinct flavour. There are three main varieties of Armagnac: Bas-Armagnac, Armagnac-Ténarèze, and Haut-Armagnac. Bas-Armagnac is the most common variety and is the most widely available. Armagnac-Ténarèze is less common and is produced in a smaller area. Haut-Armagnac is the rarest and most expensive variety. The Armagnac region is divided into two sub-regions: the Tenareze and the Haut-Armagnac. The Tenareze is the larger of the two regions and is home to the majority of Armagnac producers. The Haut-Armagnac is a smaller region located to the south.
