The variety is the result of complex interspecific hybridization. The vines have above-average vigor, exhibit an upright shoot growth habit, produce few lateral shoots, and have hermaphroditic flowers. Late bud burst reduces the risk of damage from spring frosts.
Clusters are conical, weighing 250–300 g, of medium density. Berries are medium-sized, dark blue in color with bloom, with thick skin and juicy pulp. The yield of the variety is 120–140 c/ha; the ripening period is medium.
Wines from this variety are characterized by high tannin content, a full body, and notes of cherry and blackberry. The variety is distinguished by high resistance to downy mildew and powdery mildew.
