The Incrocio Manzoni 2-14 grape variety was developed through the research of Professor Luigi Manzoni of the Conegliano School of Enology and is a cross between the Glera (Prosecco) grape and Cabernet Franc. This cross and its counterpart Incrocio Manzoni 2.15 actually originated from a mistake: the researcher aimed to obtain a grape variety with the same productivity as Prosecco (Glera) and the qualitative aspects of Sauvignon. In reality, the pollinating variety was a black grape, initially believed to be Cabernet Sauvignon. Only through DNA analysis conducted in 2010 was it discovered to be Cabernet Franc. The Manzoni Rosso grape variety did not achieve the same success as Manzoni Bianco and is mainly grown in Veneto, especially in the Marca Trevigiana, in the hilly areas between Conegliano and Vittorio Veneto.
