A red wine grape grown in Italy's tuscany, umbria, latium, marche, and emilia-romagna regions. Canaiolo Nero, as it's officially known, produces slightly bitter, rather bland wine that becomes part of the traditional blend for chianti wine. Chianti's DOCG rules for allowable grapes were changed in 1984, and Canaiolo's role was reduced from the 10-30 percent range to less than 10 percent. Naturally, this stimulated an acreage reduction in some areas. This variety, sometimes called Cagnina, is occasionally made into a red dessert wine by that same name. Canaiolo has many synonyms including Caccione Nero, Tindilloro, Uva Canina, and Uva Merla.
