What is the main grape variety used for making traditional Prosecco?

The main grape variety used for making traditional Prosecco is Glera. This indigenous grape is fundamental to the identity of Prosecco, contributing to its characteristic flavor profile, which often includes notes of green apple, honeysuckle, and pear, along with a refreshing acidity. Glera grapes thrive in the hilly regions of Veneto and Friuli Venezia Giulia in Italy, where the climate and soil conditions are particularly favorable for their cultivation.

In contrast, while Chardonnay, Pinot Grigio, and Riesling are prominent grape varieties used in other wine styles, they do not have any significant role in the production of traditional Prosecco. Chardonnay, for instance, is widely recognized for its use in Champagne and still wines, while Pinot Grigio and Riesling have their own distinct styles and flavor profiles in regions where they are primarily grown. Therefore, the unique use of Glera is what makes Prosecco distinctive from other sparkling wines.
