Barbera Bianca grapes
It is not the red wine grape’s color mutation, i.e. Barbera of Piedmont which is the Italy’s 3rd most widely grown grape variety. Actually, in the early 21st century, a DNA analysis was carried out which proved that there is no genetic relationship between these two grapes.
The grape is famous for its extreme level of acidity, the maximum of which is tartaric acid not malic acid. The tendency of acid makes the grape good for the production of the sparkling wine.
This is a sanctioned grape in the DOC (Denominazione of origine contrallata) wines of Colli Tortonedi made in the Alessandria province.
Origin and History
The exact birthplace of Barbera Bianca is unknown yet the grape was cultivated since the 19th century in the Italy’s Piedmont region when it was documented in 1825.
Wine Ampelographers suppose that this name was given to the grape because of its morphological resemblance with Barbera, typically the shape and size of the grape clusters and berries of both the grape vines.
Anyhow, in the 21st century, the DNA profiling explained that these two grape varieties are different with no genetic relation between them.
