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.

Although this grape has had a long association with Marsala, in recent years it has become widely used in a number of DOC wines:
