The variety is distinguished by high shoot vigor and the presence of hermaphroditic flowers. The leaves are large, five- to seven-lobed, and pentagonal in shape. The clusters are characterized by a large size, which ensures good yields. The berries are medium-sized, elliptical, yellow-green with specks, and covered with a thick skin.
The variety possesses high resistance to downy mildew, but is susceptible to powdery mildew, gray mold, grape moth, and mites. The grapes are used exclusively for the production of white wines, often as part of blends. It is characterized by an intense aroma with notes of citrus, laurel, and stone fruits.
