The white grape variety originates from Croatia. Synonyms are Ariavina, Brina, Brjavina, Imbrina, Königstraube, Kraljevina Crvena, Moravina, Ohainer, Piros Leanyka, Piros Oporto, Roter Portugieser and Zrjavina. The name means "kingdom" or "red kingdom". It used to be represented in Styria (Austria) under the name Roter Portugieser. Despite the synonym, it is not related to the Blauer Portugieser variety; the parentage is unknown. The late-ripening vine is susceptible to botrytis. There are varieties in white, green, reddish and speckled. It produces fresh white wines with low alcohol but high acidity and neutral taste. The variety is grown in Croatia around Zagreb and occupied 268 hectares here in 2010. In Slovenia, it is a component of the Belokranjec and Cviček wines and is grown on 179 hectares here. In 2016, only the Slovenian stock was reported (Kym Anderson statistics).
