The nectar of Valpolicella is without doubt the Corvina grape variety. Compared to the other two indigenous auxiliary grapes - Rondinella (used for structure) and Molinara (used for spiciness and acidity) - Corvina is the variety that provides the softness and cherry-tinged fruitiness typical of wines from the Verona region. Nectar Campofiorin is based on exactly these considerations, and Corvina is the only grape to be given the appassimento treatment in the making of this wine.
