Barbera Sarda is a red Italian wine grape variety that is grown on the island of Sardinia where it often used to add acidity to blends. Despite the similarities in their names, there is no known close genetic relationship between the Sardinian Barbera and the notable Piedmontese wine grape variety Barbera. Nor does there seem to be any close relationship with other grapes names Barbera, such as Barbera bianca and Barbera del Sannio.[1]
