Wine

Bianca, as a neutral grape variety, produces such a wine ; the bouquet is similar to that of Chasselas , full and harmonious in the body only when ripe. With reductive expansion, the wines become similar to Sauvignon. In some cases, however, Bianca shows a somewhat exotic note in the aroma . With medium maturity, the wines are usually thin and not very aromatic. The wine is slightly oxidative, therefore prefer reductive aging.
