The variety belongs to the third seedlessness class of sultanas, containing soft seed rudiments. The growing season is 140–150 days. The vines are vigorous, the conical-shaped bunches with a wing reach a weight of 600–900 grams, and the berries are oblong with a weight of 5–7 grams.
The plant has low frost resistance (down to -15...-18°C) and weak resistance to downy mildew and powdery mildew, but it shows resistance to grey mold. The pulp is firm and crunchy, and the skin is thin and durable. The recommended pruning length for fruit vines is 8–10 buds; the variety is well-adapted for grafting onto SO-4 and 41B rootstocks.
