Which of the following grape varieties is NOT commonly used for Armagnac?

The grape variety that is not commonly used for Armagnac is Chardonnay. Armagnac is a type of brandy produced in the Gascony region of France, and it primarily utilizes specific varietals that are well-suited to its unique production methods and climate.

Ugni Blanc, Baco Blanc, and Folle Blanche are the primary grape varieties traditionally permitted for Armagnac production. Ugni Blanc, known for its high acidity and neutrality, is particularly favored for its ability to create fresh, vibrant spirits. Baco Blanc, a hybrid grape, offers distinctive fruity flavors that complement the aging process. Folle Blanche, once the dominant variety, adds richness and complexity to the distillate.

Chardonnay, while a prestigious and widely cultivated grape, is not typically used in the production of Armagnac. Instead, it is more commonly associated with regions famous for making white wines and sparkling wines, such as Champagne and Burgundy. The absence of Chardonnay from Armagnac reflects the specific terroir and stylistic preferences of this traditional brandy.
