Armagnac is a type of grape brandy that originates from the Armagnac region of France. Interestingly, the production of Armagnac permits the use of up to 10 grape varieties, while Cognac is limited to just 6, Additionally, while all Cognacs must undergo barrel ageing, Blanche Armagnac is unique in that it remains unaged. Also, while there is no vintage Cognac, vintage Armagnac is made from a single year of distillation.
