Each boasts different soils, though all benefit from a temperate climate with an oceanic influence. Hot summers with cool nights encourage thick skins on the grapes, imparting complex flavor to the eau-de-vie.

Where is Armagnac?
Armagnac is tucked away in the province of Gascony in southwest France. There exist three zones for its production: Bas Armagnac, Armagnac Tenarèze and Haut Armagnac.

Accidents of History

Insular Ingenuity
As the Armagnac region is landlocked, its spirits had historically always been very difficult to trade, hindered even more by draconian English laws (1224-1776) that stopped anything other than their own wines traveling on the Garonne and Adour rivers. The Dutch traders circumnavigated this by encouraging producers to distill their wines, as there were no such restrictions for spirits.

A CURIOUS Rebirth
Armagnac was, and still is, made by small, artisanal, family companies of modest means. Hence, in the past they were restricted both geographically and financially in trading their products. As new, dynamic generations have taken over, and both transport and communications advanced exponentially, the notoriety of Armagnac has spread globally.
Armagnac vs Cognac
Of all the brandies on earth, Armagnac’s claim to magic reaches for the profound. It offers a stark contrast to its more polished stepbrother 300 miles to the north, Cognac.
While the production of Cognac is dominated by four industrial size companies, Armagnac continues to be crafted by small family producers using the wood-fired alembic stills of a bygone age. Also compare Cognac's 250 million bottles produced each year (most of which are exported) to Armagnac's 4 million, half of which remain in the French market. Armagnac employs up to ten different grape varieties and undergoes a single distillation, which retains more of the character of the spirit. Compare this to Cognac's double distillation, using only one grape variety (Ugni Blanc).
