What is the primary grape used in Prosecco production?

  1. Chenin Blanc

  2. Glera

  3. Sangiovese

  4. Rondinella

The correct answer is: Glera

The primary grape used in Prosecco production is Glera. This grape is native to the Veneto region of Italy and is known for its high acidity and delicate flavors, which are essential for producing the light, fruity, and floral characteristics typical of Prosecco. The grape's profile allows for the creation of sparkling wines that are aromatic yet refreshing, making it a popular choice for this style of wine. The other choices, while well-known grape varieties, are not associated with Prosecco. Chenin Blanc is primarily grown in the Loire Valley of France, Sangiovese is a key grape in Tuscany, particularly for Chianti wines, and Rondinella is often used as a blending grape in the production of Valpolicella wines. None of these grapes play a significant role in Prosecco production, affirming Glera as the definitive choice for this sparkling wine.
