This clone is characterized by lower susceptibility to bunch necrosis and grey mold compared to the base form. Morphological traits correspond to the Rhine Riesling variety: bushes are medium to vigorous, clusters are cylindrical, compact, weighing about 80 g. Berries are small, yellow-green with thick skin.
The clone is officially included in the National Register of Varieties of Hungary. It is capable of accumulating more sugar in the must during ripening than some other clones, ensuring the production of wines with a complex aroma.
