The red grape variety comes from Italy. Synonyms are Bracchetto, Brachetto, Brachetto d'Acqui, Brachetto di Alessandria, Brachetto du Piemont and Calitor. It must not be confused with the varieties Braquet Noir or Calitor Noir, despite the fact that synonyms or morphological similarities seem to indicate this. According to DNA analyses carried out in 2013, it is the result of a presumably natural cross between Muscat Blanc x unknown partner. However, this is based on only 20 DNA markers (see molecular genetics), and according to an unverifiable hypothesis, an ancestor was allegedly known in ancient times under the name Vinum Acquense. The variety, which probably originates from the mountains around Monferrato, was first mentioned in 1877 by the ampelographer Giuseppe di Rovasenda (1824-1913).
