The variety has a semi-upright habit and good vigor. Bunches are small or medium, dense, often cylindrical-conical in shape. Berries are medium, round or slightly oval, yellow-green in color, covered with thin skin and a waxy bloom, flesh is soft.
The variety belongs to the early-ripening group, with late bud burst. Moderate susceptibility to powdery mildew and grey mold is noted, however, the variety is characterized by good resistance to severe winter frosts.
Yield of the variety with short pruning is estimated as quite low, therefore long pruning and training on pergolas are recommended. The crop prefers fertile, well-lit, and well-warmed sites.
