The variety belongs to the mid- to late-maturity group. Bunches are medium-sized, cylindrical in shape, and high in density. Berries with thin skin and juicy flesh change color from greenish-yellow to golden-amber upon ripening.
The vines possess good to strong vigor. The variety is demanding of growing conditions; it develops best on warm, sunny southern slopes, preferring light, well-warming stony or sandy soils.
The variety is characterized by low winter hardiness and sensitivity to frost. In open, windy areas during flowering, flower drop may occur. Under favorable conditions, the variety is highly valued for product quality, especially when affected by noble rot.
