Variety description

10 August 2026

The variety has vigorous vine growth. The leaves are dark green, glossy, and three-lobed. The clusters are medium to large in size, often conical or cylindrical in shape, with a weight of approximately 170–240 g. The berries are yellow-green in color and may develop a pinkish blush upon full ripening.

It is a late-maturing variety, ripening from late September to early October. The variety is distinguished by high resistance to fungal diseases and frost resistance down to –26...–30 °C. The plant is very prolific, therefore it requires control of the crop load on the vine for quality berry ripening.
