The red grape variety is an interspecific new variety between Blauburger x Klosterneuburg 1189-9-77 (Seyve-Villard 18-402 x Blaufränkisch). Synonyms are Klosterneuburg 1355-3-33 and Rathay Noir. It contains genes from Vitis berlandieri, Vitis cinerea, Vitis lincecumii, Vitis rupestris and Vitis vinifera. The hybrid was crossed in 1970 by Dr Gertraud Mayer at the Klosterneuburger Weinbauinstitut (vine nursery Langenzersdorf). The former director of the institute, Emerich Ráthay (1845-1900), was honoured with the name. It was authorised as a quality wine grape variety in Austria in 2000. A similar variety is the new variety Roesler, which was also created in Klosterneuburg.
