The vines have moderate vigor and a hermaphroditic flowering type. Large cylindroconical clusters reach a mass of 700–710 g and are characterized by high density. The black-colored, medium-sized berries (3.5–4 g) have an elongated-oval shape and a thick waxy bloom.
The variety is seedless, containing only seed rudiments that are imperceptible upon consumption. The flavor is complex, with muscat and fruit undertones at a high sugar level. The fruit is firm, crisp, and possesses good keeping quality and resistance to cracking.
The variety has low resistance to downy mildew and powdery mildew. Due to reduced fertility, long pruning of the vine is recommended. The crop is sensitive to ovary shedding and reacts poorly to gibberellin, high doses of which can cause phytotoxicity.
