Rossola nera

The Rossola Nera vine is an exclusive variety grown solely in the Valtellina region of northern Italy. While it does not appear explicitly in the names of local wines, Rossola Nera is an important component in blends made from indigenous grapes, valued particularly for the vibrant acidity it contributes. This acidity plays a crucial role in enhancing the wines’ freshness, aging potential, and overall balance.

The grape’s name likely derives from the dark, reddish color of its berries. Rossola Nera grapes are medium-sized, spherical, and possess thin violet skin, which contributes to the deep ruby red hues found in the wines. The grape clusters are medium-sized, cylindrical, and compact, accompanied by medium-small, pentagonal, three-lobed leaves typical of the variety.

From a viticultural perspective, Rossola Nera exhibits excellent resistance to cold spring temperatures, which is vital in the alpine climate of Valtellina. It also displays good vigor and fertility, producing grapes that are naturally high in acidity, a prized trait for winemakers aiming for freshness and longevity in their wines. However, the variety is susceptible to certain diseases such as botrytis and powdery mildew, which require careful vineyard management.

Wines crafted with Rossola Nera are ruby red, characterized by their crisp acidity and freshness. In blends, this grape adds brightness and structure, making it an essential contributor to the distinctive style of Valtellina’s red wines.
