The variety is an intraspecific hybrid of ancient folk selection, presumably originating from Turkey. It belongs to the mid-late or late category with a ripening period of 160–170 days and requires a sum of active temperatures of about 3200 °C.
The vines are characterized by vigorous growth. Clusters are conical or cylindrical-conical, of medium density, weighing 180–230 g, and can increase significantly under irrigation. Berries are small or medium, oval, yellow-green or amber-yellow in color, with thin skin and fleshy pulp.
The flavor of the berries is harmonious, without specific aromas, and the sugar content is high (22–30 Brix). The variety has medium winter hardiness down to -19...-21 °C and low resistance to fungal diseases such as downy mildew and powdery mildew, requiring regular protective measures and agrotechnical support.
