The red grape variety comes from Italy. Synonyms are Chiavennasca Piccola, Chiavennaschino, Ciuvinasca and Nebiol Matiné. According to DNA analyses carried out in 2004, it is not, as long assumed, a Nebbiolo variety, but an independent variety. It is the result of a presumably natural cross between Nebbiolo x unknown, probably already extinct variety. The late ripening vine is susceptible to powdery mildew and botrytis. Compared to Nebbiolo, it produces red wines with a slightly higher alcohol content but less acidity and colour. The variety was once very widespread, but is now found mainly in Valtellina in the province of Sondrio in Lombardy. However, the stocks are not recorded separately; in 2016 no stock was recorded (Kym Anderson).
