Early-ripening variety with a growing season of 146–150 days. The vines are characterized by a semi-trailing growth habit, weak development, and low yield. The variety exhibits early budburst, which makes it sensitive to spring frosts.
Clusters are small, compact, and conical in shape. Berries are medium-sized, short-elliptical, black-blue in color, with skin of medium thickness. The flesh is juicy, unpigmented, and lacks a specific flavor. The variety is susceptible to powdery mildew, mites, and grey mold.
Wines from this variety are characterized by low acidity and high alcohol content. Organoleptic qualities include notes of black forest berries, spices, and mineral and herbaceous nuances. The wine possesses a balanced tannin structure and is frequently used in blends.
