Which grape is associated with high acidity and moderate to high tannins and is widely recognized as a quintessential Italian grape?

• A. Vermentino
• B. Glera
• C. Sangiovese
• D. Nebbiolo

Answer: (C)

Identifying a signature Italian red grape by its high acidity and moderate to high tannins points to a variety that defines Tuscany and many classic Italian wines. Sangiovese is the flagship grape of Tuscany, giving wines like Chianti and Brunello di Montalcino their bright, food-friendly acidity and structured tannins. That acidity helps the wine stay vibrant with age and across paired dishes, while the tannins provide backbone without overpowering the red fruit and spice notes. Because of its central role in Italy’s most famous wine styles and regions, Sangiovese is widely recognized as a quintessential Italian grape.

Vermentino and Glera are white varieties, so they don’t fit the profile of a red grape with this specific structural balance. Nebbiolo does have high acidity and high tannins and is iconic in Italy, but its strongest association is with Piedmont’s Nebbiolo-based wines, whereas Sangiovese more broadly represents the Italian red-wine identity.
