The variety is the result of crossing Alphonse Lavallée and Perlette. The plant is characterized by vigorous or moderately vigorous growth. The clusters have a conical shape with wings, are medium-dense, and weigh from 290 to 500 grams. The oval berries are dark purple in color and have crisp, fleshy pulp and thick skin.
The variety is classified as seedless, although seed rudiments may be present in the berries. The ripening period varies from the beginning of August to the second half of September depending on growing conditions. The plant is sensitive to low temperatures, withstanding frosts down to -18...-22 °C.
Good resistance to powdery mildew and gray mold is noted, with a possibility of downy mildew infection in rainy years. The variety is demanding in terms of heat, light, and moisture supply, and requires the installation of trellises and the implementation of preventive treatments.
