The leaf is rounded, five-lobed, and weakly incised. The bunches are medium-sized or small, dense, with a characteristic reddish hue of the peduncle before ripening.
The berries are small, dark blue with a waxy bloom and thick skin. The variety is relatively resistant to gray mold, but susceptible to downy mildew, anthracnose, and late spring frosts. It requires long pruning and green operations for full maturation.
