The variety is the result of crossing the Villard blanc and Chasselas Bouvier varieties. The vine is characterized by medium vigor, an open canopy, and moderate lateral shoot formation. The bunches are small, weighing 90–150 g, cylindrical in shape, and of moderate density.
The berries are medium to small, round or round-oval, and yellow-green in color. The flesh is juicy, with a harmonious taste and a high sugar content reaching 20–28%. The variety is distinguished by high yield and is not prone to berry shedding even when overripe.
The plant possesses high frost resistance, withstanding temperature drops down to -25...-27°C. Due to its complex resistance to downy mildew, powdery mildew, and gray mold, the variety requires fewer preventive treatments.
