The variety is a complex interspecific hybrid obtained by crossing the Guzal Kara and Seyve-Villard 12-375 varieties. The growing season is 150–160 days, with ripening occurring in late September. The bushes are vigorous with powerful vines; arbor training is recommended.
The bunches are conical or cylindrical-conical, of medium density, weighing from 300 to 600 g, with individual specimens reaching 1 kg. The berries are oval, dark blue with a waxy bloom, weighing 5–7 g. The flesh is fleshy and crisp, the skin is firm, and sugar accumulation is 17–20 Brix.
The variety possesses complex resistance to downy mildew, powdery mildew, and gray mold. Frost tolerance is increased, withstanding temperatures down to -22...-25 °C; in case of damage to the primary buds, it is capable of fruiting from latent buds.
