An early ripening variety originating from Lower Styria. Genetically, it is the result of a cross between Grüner Sylvaner and Blauer Zimmettraube. The vines have above-average vigor, and the shoots mature well. The leaves are round, 3- or 5-lobed, and medium-sized.
The clusters are conical, medium-sized, weighing about 160 g, and can vary in density. The berries are dark blue, with thin skin and juicy flesh. The variety is characterized by high yield, although excessive cropping reduces product quality.
The variety has low resistance to downy mildew and powdery mildew and is susceptible to grey mold. Due to relatively late budburst, it is relatively resistant to spring frosts.
