The variety belongs to seedless table types. The berries have a black or dark purple color and are characterized by a small size. The taste is sweet, crunchy, with a distinct muscat hint. Under certain conditions, edible, imperceptible seed rudiments may appear.
The plant has a mid-late ripening period, is resistant to rain, and handles transportation well. During cultivation, sensitivity of berry coloration to yield-increasing methods is noted, as well as specific characteristics of pedicel development.
