Grillo, also known as Riddu and Rossese bianco, is a white Italian wine grape variety that withstands high temperatures and is widely used in Sicilian winemaking and, in particular, for making Marsala. Its origins are uncertain, but it may have been introduced into the island of Sicily from Apulia. It was already widely planted in the Province of Trapani by 1897; today it may be grown throughout Sicily and also in the Aeolian Islands.
