Variety description

10 August 2026

The variety forms a vigorous thornless shrub with a semi-trailing or semi-erect growth habit. The canes reach a length of 4–6 meters and require mandatory tying to trellises due to a tendency to lodging.

The berries have an average weight of about 5–7 grams and a dark, almost black color. The taste of the fruit is sweet with a slight acidity, manifesting upon full ripening. The variety has good transportability.

Fruiting begins in the second half of August and lasts until the end of September. The variety is distinguished by high yield and good resistance to diseases and pests. Winter hardiness is estimated as moderate; in regions with severe winters, covering is required.
