| History |
Since the early '500s and some Indigene authors of Trevigiano, since it matured earlier, it was used to "prosecco" Prosecco, especially in cold vintages. Cultivated often in high and difficult areas, along with Verdiso. In fact, Bianchetta is a generic name, with which are indicated grapes with different ampelographic characteristics. It is with the seventeenth century that we come to recognize a Bianchetta cultivated in Treviso, probably by Caronelli (1788); Then we find a detailed description of Zava (1901) and Dalmasso (1937) confirming its ancient presence in the Treviso area. In the past it was very widespread also in the region of Atenes, Valsugana and Valdadige, and in Bolzanese with the name Vernaccia bianca or Pavana. |
