The vines have medium or above-medium vigor; shoots ripen well. The variety is medium-late: the period from bud burst to technical maturity is 140–160 days. It requires winter covering due to low frost resistance (down to -21...-22 °C) and needs preventative treatment against fungal diseases.
Clusters are large, cylindrical-conical, often with pronounced “wings”; density can vary. Berries are very large, round or slightly flattened, colored dark-violet, almost black with a bluish waxy bloom. The flesh is firm, juicy, and crisp.
