The variety belongs to the late-ripening group, requiring 155–160 days to reach technical maturity with a sum of active temperatures of 2950–3000 °C. The vines are vigorous; the crown is pyramidal in shape with vertically growing shoots.
The berries are medium-sized, round or oval, golden-yellow in color with a bronze tan. The pulp is juicy, and the skin is firm. The variety is capable of accumulating sugars up to 25–30% while maintaining acidity at a level of 7–10 g/l.
