Haut-Armagnac ("Upper Armagnac"; Occitan: Haut Armanhac), one of the three terroirs (plantation areas) in the Armagnac area where the grapes for the distillation of the Armagnaceau-de-vie can be cultivated. It lies to the south and east of Bas-Armagnac and Armagnac-Ténarèze, the two other areas, and is much the largest of the three.
The area is called "white Armagnac" because of the abundance of limestone. It includes the eastern part of the department of Gers and a small part of Lot-et-Garonne. Viticulture was developed here in the 19th century to meet the high market demand. Today the original vineyards still exist but only represent a small amount of the production.
Haut-Armagnac includes the towns of Marciac and Lectoure and the capital of Gers, the city of Auch.
The vineyards are scattered like islands over the chalky clay hills.
