The variety was obtained by crossing Katta-Kurgan and Parkent varieties. The bushes are characterized by vigorous growth and require significant space for development. The vegetation period is 120–140 days. Long pruning of canes to 10–20 buds is recommended.
The clusters have a weight from 550 to 1000 g, with individual specimens reaching 2–3 kg. The berries, weighing 11–12 g, have a pink color, thin skin, and a waxy bloom. Sugar accumulation reaches 20–25 Brix. With excess moisture or irrigation fluctuations during ripening, the berries may crack.
The variety has weak resistance to downy mildew and powdery mildew, as well as low frost hardiness, withstanding up to -18...-21 °C, which requires mandatory covering in most regions. The grapes are suitable for fresh consumption, drying for raisins, and culinary processing.
