The term Drupeggio is a local synonym used primarily in Umbria and refers to the Canaiolo Bianco grape variety. Canaiolo Bianco is a traditional Tuscan grape variety, now almost completely disappeared. Although it is included in the DOC regulations of Carmignano and Valdinievole along with Malvasia Bianca Lunga and Trebbiano Toscano, only a few hectares remain under cultivation, and no new plantings have been reported in at least ten years. The situation is further complicated by the fact that in the area, the Canaiolo Bianco grape is often confused with Vernaccia di San Gimignano. In the Orvieto area, the Canaiolo Bianco grape is known as Drupeggio.
