Variety description

10 August 2026

The variety is an interspecific hybrid obtained by crossing the SV 12375 and Bouvier varieties. The vines are characterized by medium vigor. The bunches are small, cylindrical in shape, of moderate density, weighing 90–120 g. The berries are medium to small, weighing about 2 g, have a round or oval shape and a yellow-green color.

The variety matures in early to early-mid terms; in northern regions, the harvest period shifts to late September – early October. The produce is characterized by high sugar content in the range of 18–28% with an acidity of 7–9 g/l. The flesh is juicy and covered with a thin skin.

The plant possesses high resistance to downy mildew and powdery mildew, while being sensitive to bark necrosis. Frost resistance is rated as medium, however, the variety demonstrates an ability for rapid recovery after damage.
