Trebbiano is an Italian wine grape, one of the most widely planted grape varieties in the world. It gives good yields, but tends to yield undistinguished wine. It can be fresh and fruity, but does not keep long. Also known as ugni blanc, it has many other names reflecting a family of local subtypes, particularly in Italy and France. Its high acidity makes it important in Cognac and Armagnac productions.

Cognac is a variety of brandy named after the commune of Cognac, France. It is produced in the surrounding wine-growing region in the departments of Charente and Charente-Maritime.
