The variety was obtained by crossing the varieties Pozsonyi Fehér and Csaba Gyöngye. The growing season ranges from 105 to 125 days with a sum of active temperatures of about 2250 °C. The bushes have medium vigor, and the shoots are semi-spreading. The vine matures by 80–90%. The variety is relatively resistant to downy mildew and powdery mildew, but can be affected by spider mites.
The clusters are medium-sized, weighing 120–150 g, conical in shape, often branched, and of medium density or loose. The berries are medium-sized, round, light golden in color, with a thick and firm skin. The yield is about 80 c/ha on non-irrigated plots.
The variety is technical, but due to its early maturity and muscat taste, it is sometimes used as a dual-purpose variety. It is used for the production of high-quality dessert wines, natural semi-sweet muscat wines, and quality juice.
