The variety is early-ripening, with a maturation period of 110–120 days. The bushes have medium growth vigor. The clusters are large, weighing from 340 to 600 g, with a cylindrical-conical shape and a structure ranging from moderately loose to very loose.
The berries are large, oval-shaped, red-violet in color with a smoky waxy bloom and characteristic grooves at the apex. The flesh is firm and crunchy; the flavor is harmonious with a light muscat aroma. The variety is prone to uneven berry ripening within the cluster.
The plant possesses low resistance to downy mildew, powdery mildew, and gray mold, as well as low winter hardiness (down to -15...-18°C). It requires regular protective measures and proper agronomic practices. Short pruning of fruit canes to 6–8 buds is recommended.
