==DOC rules== To be used in Prosecco, Verdiso must be harvest to a yield no greater than 12 tonnes/hectare. The wine must be at least 85% Glera with Verdiso permitted to fill in the remaining 15% of the blend along with Chardonnay, Pinot gris and Pinot blanc. The finished wine must attain a minimum alcohol level of 10.5%. Separate bottlings of Prosecco that contain Verdiso may be labeled as Superiore di Cartizze, provided the wine reaches a minimum alcohol level of 11% and is made exclusively from grapes grown in vineyards on the hill of Cartizze, which is at an altitude of around 1,000 feet.
