The red grape variety originates from Italy. Synonyms are Brachetto Ligure, Negrara, Terodola and Tirodola. A first documentary mention was made in 1824 by the biologist Ciro Pollini (1782-1833). Despite seemingly suggestive synonyms or morphological similarities, it must not be confused with the Negrara Trentina, Raboso Veronese or Teroldego varieties. DNA analyses carried out in 2008 revealed a close relationship with the Gruaja variety. The medium to late ripening variety is vigorous. It is grown in the Veneto region, mainly in the province of Verona, as well as Vicenza and Padua, where it is used in the DOC wines Bardolino, Breganze, Valdadige and Valpolicella. However, no stocks were reported in 2016 (Kym Anderson statistics).
