First of all, it must be produced exclusively in the delimited region of the appellation, which extends over three departments in southwestern France: Gers, Landes and Lot-et-Garonne.
Secondly, Armagnac must be made from certain authorized grape varieties, such as Baco, Ugni Blanc, Colombard or Folle Blanche.
The grapes are harvested by hand, and the distillation must be done on site, according to traditional methods.
Aging is also a key step in the production of Armagnac. It must be aged in oak barrels for at least one year, but most Armagnacs are aged much longer, sometimes for several decades.
Finally, the Armagnac must be bottled in the region of production, and each bottle must bear a mention of the producer, the date of bottling, as well as the mention “Appellation d’Origine Contrôlée Armagnac”.
