Barbera bianca is a white Italian wine grape variety that is grown in the Piedmont wine region of northwest Italy. Despite being named Barbera bianca, the grape is not a color mutation of the red Piedmontese wine grape Barbera that is the third most widely planted grape variety in Italy. In fact, DNA analysis conducted in the early 21st century shows no genetic relationship at all between the two grape varieties.[1]
Barbera bianca is noted for its high acidity levels, the vast majority of it tartaric rather than malic acid. This propensity for high acid lends the grape well to sparkling wine production. Barbera bianca is a permitted grape variety in the Denominazione di origine controllata (DOC) wines of Colli Tortonesi produced in the province of Alessandria.[1]
