The red grape variety comes from Italy. Synonyms are Basgnano, Bazano, Bersegano, Besegano, Besgana, Besgano di San Colombano, Besgnano, Colombana and Colombano Rosso. It was already mentioned at the end of the 16th century in a work of the agronomist Giovanni Soderini (1526-1596). The name probably derives from the monastery of San Colombano in Bobbio (Emilia-Romagna). It must not be confused with the Besgano Nero variety, despite the apparent synonyms or morphological similarities. According to DNA analyses carried out in 2013, it originates from a presumably natural cross between Sciaccarello(Mammolo) x unknown partner. The late ripening vine is mainly used in blends. It is mainly cultivated in Tuscany, where it is permitted in the DOC wine Colli di Luni, for example. There are other stocks in Emilia-Romagna. There is no connection to the Lombard DOC wine San Colombano al Lambro. In 2010 there were 38 hectares of vineyards, with a strong downward trend; in 2000 there were 126 (Kym Anderson).
