The red grape variety is a new variety between Cabernet Franc (red) x Prosecco = Glera (white). Synonyms are I. M. 2-15, Manzoni Nero and Manzoni Rosso. The cross was made by the breeder Luigi Manzoni (1888-1968) in the 1920s at the viticultural institute of Conegliano in Veneto (Italy). The vine owes its origin to a coincidence, because the breeder had actually planned a cross between Prosecco x Sauvignon Blanc. However, due to a mistake, Cabernet Franc was used. Due to a mistake, however, Cabernet Franc was used, resulting in a red variety. The true parentage, however, only became apparent during DNA analyses carried out in 2010, because until then Cabernet Sauvignon was assumed to be the parent variety. The late-ripening vine is resistant to winter frost. It produces red wines with soft tannins and aromas of black fruits, which are mainly used as blends. The variety is cultivated in Veneto in the province of Treviso, where it is permitted in the Colli di Conegliano DOC wine. In 2016, 72 hectares of vines were designated (Kym Anderson statistics).
