The white grape variety is a new breed between Red Riesling x Bouvier. It was crossed in 1963 in the Czech Republic at the South Moravian breeding station Znojmo by C. Míša and M. Zboril. The plant variety protection was granted in 2001. The early-ripening vine is moderately resistant to fungal diseases except botrytis. It yields fruity, full-bodied white wines with moderate acidity. It is cultivated in the south-eastern part of Morava (Moravia). In 2010 the area under cultivation was four hectares (Kym Anderson).
