The variety is classified as late, with a ripening period of 150–160 days. The vines have very high vigor. Clusters are large, weighing from 800–900 g, cylindrical-conical or broadly conical in shape, with a moderately loose structure. Berries are round, weighing about 6 g, with thin, durable skin and firm, crisp flesh. The variety is seedless, with barely perceptible rudiments.
The plant has high yield and excellent transportability; clusters can be stored in cold storage for up to 3 months. The variety is resistant to gray mold and berry cracking, but shows susceptibility to downy mildew and powdery mildew, and has low winter hardiness (down to –15...–18°C).
Medium pruning to 6–8 buds or 35–40 buds per vine is recommended. The variety is highly compatible with rootstocks 1103 Paulsen, 775 Paulsen, SO4 and is suitable for pergola training with a recommended planting density of 2.5 × 2.5 m.
