Which grape variety is commonly found in both Valpolicella and Bardolino?

The grape variety commonly found in both Valpolicella and Bardolino is Rodinella. This grape is one of the indigenous varieties of the Veneto region in Italy, and it plays a significant role in the production of the various red wines from these areas. Valpolicella and Bardolino are primarily made from a blend of grapes, with Rodinella typically included alongside other local varieties such as Corvina and Molinara.

Rodinella is known for contributing fresh fruit flavors and a balancing acidity to the wines, which is essential for the character of both Valpolicella and Bardolino. By including Rodinella in the blends, winemakers achieve a wine that is approachable and food-friendly, which is characteristic of these two well-regarded styles from the Veneto.

The other grape varieties listed do not commonly share this dual presence in Valpolicella and Bardolino. Merlot and Cabernet Sauvignon are international grape varieties that are less frequently used in traditional Italian blends from this region, while Garganega is primarily recognized as a white grape used in the production of Soave wines, not red wines like Valpolicella or Bardolino.
