Variety description
10 August 2026
The variety has medium vigor; leaves are three- or five-lobed and smooth. Clusters weigh 90–130 g, have a cylindrical or cylindrical-conical shape, and are characterized by high density. Berries are round in shape, light green in color with a golden hue and characteristic dark spots.
The variety is characterized by medium winter hardiness (down to –19...–20 °C) and low resistance to fungal diseases, including downy mildew, powdery mildew, and gray mold. Yields are subject to fluctuations due to a tendency for ovary shedding under unfavorable conditions during the flowering period.
The grape is sensitive to soil composition and does not tolerate an excess of lime. The produce is valued for its juicy pulp and muscat aroma, which allows the variety to be used for making dry and dessert wines, as well as for fresh consumption.
