Armagnac is distilled using what's called an alembic pot still, resulting in a rougher spirit. But once this is combined with age, it turns extremely complex. There are three appellations in Armagnac - Ténarèze, Bas and Haut. Producers there have been making Armagnac for hundreds of years, even before cognac producers. Who are arguably more popular. Cognacs are commonly made using one type of grape only which is called Ugni Blanc. Armagnac makes the most of using three additional types of grapes - Bacco, Folle blanche and Colombard.
