Variety description

10 August 2026

The variety is a complex interspecific hybrid, whose pedigree includes the varieties Misket Kaylaski and a hybrid form from the cross of Villar blanc and Muscat Hamburg. The purpose of the variety is versatile: it is suitable for both fresh consumption and for the production of juices and muscat wines.

The maturity period is 110–125 days, and the bushes have medium vigor. The clusters are cylindro-conical, medium-sized (250–300 g), of moderate density or loose. Large round berries weighing about 4 g have a white or white-green color, which acquires a golden hue upon ripening, and thin, firm skin.

Sugar content levels are 19–21% with an acidity of 6–7 g/l. The variety is characterized by increased resistance to downy mildew, powdery mildew, and gray mold. Depending on the climatic zone, the variety is considered to require covering or is conditionally hardy without covering.
