The variety belongs to the early ripening period with a growing season of about 129 days at an active temperature sum of 2600°C. The bushes have medium vigor. Leaves are small or medium, rounded, five-lobed, deeply dissected, with a reticulate-wrinkled surface and bristly pubescence on the underside.
Clusters are of medium density, conical or cylindrical-conical in shape, with a mass of 90–150 g. Berries are rounded, with a mass of 1.1–2.2 g, dark pink in color with a thick waxy bloom; when overripe, they can acquire a purple shade. The skin is thin, the flesh is tender, and the taste is simple. Yield is 80–100 c/ha.
The variety has weak resistance to fungal diseases, winter frosts, and drought, and requires mandatory covering for the winter. Shoots ripen well, and the harvest is characterized by satisfactory transportability.
