The vine is widespread in the province of Treviso , but its origin is uncertain. In fact, as with many vines with similar names, the name was used to indicate the color of the berries and often indicated a group of grapes that were also different from each other. In the Treviso Hills since the 18th century there is news of a grape called "Bianchetta ". The history of this vine certainly begins before then, but the first written records date back to that period. Documents from the time report the oenological characteristics of Bianchetta Trevigiana, stating that its best use is to produce a sweet wine , leaving the grapes to dry for 4 or 6 days in the sun. This vine is today often used in combination with other vines, such as Verdiso , to accompany Glera in the Prosecco blend.
