The variety is a hybrid of the Cardinal variety and an unknown seedless variety. The plant is vigorous; to achieve industrial productivity, it requires the use of large training systems and long pruning of fruit canes to 6–8 buds.
Clusters are conical, medium-dense, weighing from 500 to 700 g, sometimes more than 1 kg. Berries are slightly oval, large, 18–22 mm in size, belonging to seedlessness class I–II. The pulp is firm and crisp, the taste is harmonious, often with a light muscat aroma.
The variety has moderate frost resistance within the range of -21...-23°C. Disease resistance is typical for Vitis vinifera species: relatively resistant to gray mold, but has low resistance to powdery mildew. Under adverse weather conditions, berry cracking is possible.
