Bianchetta Trevigiana

Likewise, despite sharing the synonym Vernaccia (the root of which translate to "vernacular" or "local"[2]) with the notable Tuscan and Sardinian wine grapes, Biancheta Trevigiana appears to have no close relationship with any of those varieties.

The 1679 account from Italian writer Agostinetto di Cimadolmo described Bianchetta Gentile as growing in the Treviso region.

[1] The first detailed account of Bianchetta Trevigiana was in 1937 by grape-breeder Giovanni Dalmasso at the Istituto Sperimentale per la Viticoltura in Conegliano.

Despite having very thick-skins, the grape is very susceptible to the viticultural hazard of powdery mildew and also has poor resistance to frost damage that may occur early in the growing season.

[1] In 2000, there were 65 hectares (160 acres) of Bianchetta Trevigiana, which represents a dramatic drop in cultivation from the 17th and 18th century when the grape was widely planted in the provinces of Belluno and Verona.
