French-American hybrid created in France in the 1930s by Jean-Louis Vidal who was hoping to invent a hearty variety that could be used in making Cognac. Vidal’s parents are trebbiano Toscano (ugni blanc) and rayon d’or, itself a hybrid. Now grown primarily in Virginia, New York State, and Canada. In the latter two places, it is made not only into dry wines but also into some terrific ice wines. Also known as vidal blanc.
