The variety belongs to the eco-geographical group of oriental table varieties. The growing season is 165–170 days. Bushes are medium-vigorous; powerful training systems and long pruning are recommended. Leaves are medium-sized, deeply dissected, with wine-red petioles and veins.
Clusters are conical, branched, weighing 250–300 g. Berries are black with a thick waxy bloom; the skin is elastic. Yield is 70–90 c/ha with a sugar content of 18–20% and acidity of 6–7 g/l. The variety has high transportability, develops better on well-moistened soils, and berry shelling is weak.
The variety is relatively resistant to powdery mildew and grape berry moth, slightly susceptible to gray mold, but less resistant to downy mildew. Vine maturation is incomplete.
