The variety has vines of medium vigor with vertically oriented shoots and insignificant lateral shoot formation. The shoot tip is densely pubescent and yellow-green in color. The leaves are small or medium, deeply lobed, and three- or five-lobed.
The clusters are small or medium, cylindrical-conical, and dense. The berries are of medium size, round, yellow-green in hue, and have juicy flesh and thin but firm skin. The variety is characterized by good winter hardiness and moderate resistance to downy mildew and powdery mildew, requiring preventive treatments.
The yield of the variety is medium, higher than that of Riesling. The grapes are capable of accumulating high levels of sugar, and due to the firm attachment of the clusters to the vine, late harvesting is possible for the production of concentrated wines.
