An early or early-mid season ripening variety with vigorous bushes and perfect flowers. The leaf is rounded or pentagonal, three- or five-lobed. Clusters are medium-sized, cylindrical or cylindrical-conical, medium-dense or dense. Berries are medium-sized, rounded, dark blue with a thick waxy bloom.
The plant is undemanding to soil composition and possesses high resistance to diseases, drought, and frost, however, it requires covering in regions with a harsh climate. Due to high and stable yields, the bushes require crop load management.
Wine variety for the production of wines characterized by deep color and balanced acidity. The flavor and aroma profile includes notes of cherry, blackberry, plum, spices, and vanilla. The wines are suitable for consumption at a young age or for long aging.
