The variety was obtained as a result of hybridization of the Bolgar and Perlette varieties. The vines are vigorous, most often cultivated as grafted plants on SO4 and 41B rootstocks. The growing season is about 126 days; full ripening of the clusters occurs in mid-August.
Clusters are of medium size, weighing 256–300 g, conical in shape, loose or of medium density. Berries are medium-sized, oval, green-yellow in color, with crisp flesh and a harmonious taste. The sugar content is 20–21% with an acidity of 5.0–7.8 g/l; during overripening, sugar can reach 24–26%.
Berries store well on the vines and are capable of natural drying into raisins in dry weather. The variety is characterized by low resistance to fungal diseases and frost, requiring careful maintenance and training.
