Cabernet is loosely used as an abbreviation for either or both of the black grape varieties cabernet franc and cabernet sauvignon. In north-east Italy in particular there has been a certain lack of precision about the precise identity of the Cabernet grown and allowed into the many Cabernet docs, although Cabernet Franc has tended to predominate. Elsewhere, Cabernet is more likely to be an abbreviation for Cabernet Sauvignon. Cabernet is also a popular prefix for recent German and Swiss hybrids such as Cabernet Blanc, Cabernet Carbon, Cabernet Carol, Cabernet Colonjes, Cabernet Cortis, Cabernet Dorio, Cabernet Dorsa (the most popular), Cabernet Jura, and Cabernet Mitos.
