Early maturity variety. Clusters are medium to large, cylindrical-conical in shape, loose. Berries are medium-sized, oval or ellipsoid in shape, with thin skin and white bloom. Upon ripening, the berries acquire a shade from light yellow-green to amber-yellow and become translucent.
The pulp is juicy and melting, possessing a neutral taste and high sugar content. The plant is distinguished by vigorous growth and high fertility, with secondary shoots also being fruitful. The variety prefers fresh, non-waterlogged soils and warm, illuminated locations.
The plant is prone to early bud break. During cultivation, millerandage and ovary drop may be observed. Due to the high growth vigor, short or medium pruning is recommended to prevent exhaustion of the vine.
