The variety has high vigor, the flower is bisexual. Clusters are cylindro-conical in shape, of medium density, weighing 500–600 g or more. Berries weighing 5–8 g (up to 10 g) have an oval or elongated-oval shape, a dark blue, almost black color, and a thick waxy bloom.
The flesh is firm, meaty, and crispy, with high sugar accumulation of 18–21% and class I–II seedlessness. The skin is virtually imperceptible when eaten. The berries are firmly attached to the pedicel, are characterized by good transportability, and are suitable for long-term storage.
The variety has a very early ripening period, high yield, and does not require specific agrotechnical practices. Resistance to diseases is low; it requires winter covering.
