Besgano bianco is a white Italian wine grape variety that was historically used in the production of the dessert wine Vin Santo, blended with Malvasia Bianca Lunga and Verdea, but today is rarely planted and is more often used for table grape production than winemaking. The grape is also known as Colombana bianca but it is not a color mutation of the Tuscan and Emilia-Romagna wine grape Colombana nera.
