ActiveVitis vinifera L. · Common grape vine

10 August 2026
The vine is medium-vigorous with weak lateral shoot formation. Leaves are wrinkled, with dense felt-like pubescence on the underside, and vary from entire to five-lobed. Clusters are medium-sized, weighing 250–300 g, often branched, and density may vary.
Berries are medium-sized, round, with thin skin. The variety is characterized by a high capacity for sugar accumulation (22–24 Brix and higher) and is prone to raisin formation when overripe. Frost resistance is approximately –22 °C.
Resistance to major fungal diseases is typical of European grape varieties; it requires chemical protection. Dense clusters are susceptible to Botrytis cinerea (gray mold). Yield is medium and inconsistent, varying from 50 to 120 c/ha.
