Variety description
10 August 2026
The variety is a complex interspecific polyhybrid obtained by crossing the varieties 'Diana' and 'Chambourcin'. The vine has medium vigor and good shoot ripening, while producing a small number of lateral shoots. The flowers are bisexual, which contributes to stable fruiting.
Leaves are medium-sized, three- or five-lobed, almost entire, with slight pubescence on the underside. Bunches are medium-sized, weighing 150–200 g, cylindrical-conical in shape. Berries weigh 1.5–1.7 g, are round, dark blue in color with a waxy bloom, and contain juicy pulp and colored juice.
The variety belongs to the PIWI group, showing high resistance to downy mildew, powdery mildew, and gray mold. The ripening period is 135–140 days. Product quality is characterized by a juice sugar content of 20–24% and acidity of 7–9 g/l, which allows it to be used in organic viticulture.
