The red grape variety (also Nessuno Conosciuto) comes from Italy. The earliest mention dates back to 1882 and the few synonyms testify to this relatively short history. According to DNA analyses carried out in 2006, it is the result of a presumably natural cross between Corvina Veronese and an unknown variety. The medium to late-maturing, very high-yielding vine is resistant to most fungal diseases, but susceptible to wood disease Esca. It produces colourful and acidic red wines with cherry aromas. The variety is mainly cultivated in the regions of Veneto and Lombardy, where it is mainly used as a blending partner for the Corvina Veronese, Corvinone and Molinara varieties. It is, for example, approved for the DOCG/DOC red wines Bardolino and Valpolicella, as well as Garda Colli Mantovani. In 2010, 2,479 hectares were registered in Italy and 2 hectares in Australia. The variety is ranked 165th in the worldwide grape variety ranking.
