Which grape is primarily used to produce Prosecco?

Prosecco is primarily produced from the Glera grape, which is a white grape variety native to the Veneto region of Italy. The use of Glera in the production of Prosecco is essential because it imparts the wine's characteristic lightness, freshness, and floral notes, which are key features that define Prosecco as a sparkling wine.

The Glera grape is known for its ability to retain acidity while developing fruity and aromatic qualities, making it ideal for sparkling wines that are enjoyable when consumed young. This grape variety is typically harvested early to preserve its acidity, contributing to Prosecco’s vibrant profile.

While other grape varieties like Chardonnay and Sauvignon Blanc are popular in various wine styles and regions, they are not the primary components in the production of Prosecco. Similarly, Riesling, known for its aromatic qualities and fruitiness in a different context, does not play a role in creating Prosecco. Thus, Glera is the correct and key grape responsible for this iconic Italian sparkling wine.
