The variety is the result of crossing Rosa menna di vacca and Mathiász Jánosné muskotály. The plant is vigorous and suitable for cultivation on pergolas. Clusters are large, winged, medium-dense to loose, with a long peduncle. Berries are yellow with a waxy bloom and delicate muscat aroma.
The variety belongs to the late-maturing group, with ripening beginning at the end of September. The crop is not demanding of soils, tolerates drought well, but has low frost resistance and shoots are sensitive to frost. Due to susceptibility to rot, the variety requires protection in wet weather.
