The variety is the result of a natural cross between Blaue Zimmettraube and Grüner Sylvaner. The plant has above-average vigor, and shoots ripen well. Leaves are medium-sized, rounded, three- or five-lobed, without pubescence. Flowers are bisexual.
Clusters are medium-sized, weighing about 160 g, conical, with varying density. Berries are dark blue, rounded or oval, with thin skin and juicy pulp. The variety is high-yielding and resistant to spring frosts, but shows low resistance to downy mildew, powdery mildew, and gray mold.
