Barbera del Sannio is a red Italian wine grape variety that is grown in the Campania region of southern Italy. Despite the similarities in name and appearance, the grape has no close genetic relationship with the Piedmont wine grapes Barbera or Barbera bianca or the Sardinian wine grape Barbera Sarda and is, instead, more closely related to the Campanian varieties Casavecchia and Catalanesca and the Apulian grape Nero di Troia.[1]
In Campania, Barbera del Sannio is often used as a blending variety that adds color and aroma notes to the wine but it is also permitted to be made as a varietal wine in Denominazione di origine controllata (DOC) of Sannio.[1]
