Barbera Bianca is a white grape variety native to the Piedmont region of Northern Italy. Despite its name, it is not related to the red Barbera grape.

Barbera Bianca produces light-bodied wines with a pale yellow-green colour and aromas of green apple, melon and lemon. On the palate, it is characterized by crisp acidity and light fruit flavors such as citrus and stone fruits.

Barbera Bianca is grown mainly in Piedmont and is allowed in Colli Tortonesi Bianco DOC. Barbera Bianca is a vigorous and productive variety which tends to produce high yields. While it is typically made as a varietal wine, it is also blended with other white varieties. The grapes are often harvested early in the season in order to retain the acidity. In Piedmont, Barbera Bianca is made in a variety of styles, from dry and crisp to sweet and fruity. It can be made with or without oak and can be still or sparkling. Barbera Bianca is an excellent food wine, pairing well with seafood, grilled vegetables and light pastas.

Barbera Bianca has clusters and berry shape similar to those of the red Barbera, as well as similarly high acidity but has a distinct DNA profile hence cannot be considered a colour mutation of it.
