Folle Blanche is a white grape variety primarily grown in the Loire Valley of France. It is known for its high acidity and aromatic qualities, making it suitable for producing crisp, refreshing wines. Folle Blanche is often used in the production of Cognac and Armagnac, where it contributes to the fruity and floral characteristics of these spirits. Historically, Folle Blanche was more widely planted in France, but its popularity has declined due to its susceptibility to disease and lower yields compared to other grape varieties. Today, it is mainly cultivated in specific regions, where it is appreciated for its unique flavor profile and contribution to traditional winemaking.
