The white grape variety comes from Romania. Synonyms are king grape, Lampar, Lampar Fardevany, Lampartner, Lampau, Lampor, Lampor Fehér, Mustafer, Mustos, Mustos Beli, Mustosfehér and Stafttraube. It must not be confused with the varieties Frâncușă (Mustoasă de Moldova) or Juhfark (Mustafer), in spite of apparently indicative synonyms or morphological similarities. The exact origin is unknown, but the name suggests the Măderat vineyards in western Romania. The late ripening, high-yielding vine is susceptible to powdery and downy mildew, but resistant to botrytis and frost down to minus 18 °Celsius. It produces aromatic, very acidic white wines with aromas of citrus, which are excellent for the production of sparkling wine and brandy. The variety is mainly cultivated in the Minis Măderat (Banat) area. In 2010, it occupied a total of 255 hectares of vineyards in Romania (Kym Anderson).
