The vines are characterized by high vigor. Clusters are small, cylindrical or cylindro-conical in shape, and of medium density. Berries are small, round, greenish-white in color, and covered with a thick skin with a medium-density waxy bloom.
The variety has low resistance to fungal diseases such as powdery mildew and downy mildew, and low frost hardiness. At the same time, due to the structure of the cluster and the thick skin, it shows resistance to gray mold. It is capable of raisin-like shriveling on the vine, which is used by winemakers to concentrate sugar and aromatics.
