Variety description

10 August 2026

An early-ripening variety with a growing season of 113–140 days. The bushes have medium vigor, form side shoots moderately, and have sparse foliage. The variety shows relative resistance to downy mildew, low resistance to powdery mildew, and poor drought tolerance. Frost resistance is rated as low, down to -19°C.

Bunches are medium, weighing 125–150 g, conical in shape, often branched and loose, which reduces susceptibility to grey mold. Berries are medium, rounded, light-golden in color, with a firm skin and juicy flesh. The variety is intended for fresh consumption as well as for the production of white muscat wines.
