Biancone di Portoferraio
Variety of grape / From Wikipedia, the free encyclopedia
Biancone di Portoferraio is a white Italian wine grape variety that is grown almost exclusively on the island of Elba off the coast of Tuscany. Some ampelographers have speculated that the grape may have originated on the French island of Corsica where the grape shares a close genetic relationship with the Corsican wine grape Biancu Gentile (also known as just Biancone).[1]
