The white grape variety originates from Hungary; the name means "Green of Buda" (district of Budapest). Synonyms are Budai, Boudaisky Vert, Budimsko Zeleno, Zelenka, Zöld Budai, Zöld Szölö, Zöldfehér and Zöldszölö. The parentage is unknown. The medium-maturing vine is susceptible to botrytis and downy mildew. It yields full-bodied, yellow-coloured white wines with aromas of green apples and vegetal notes. The variety was once one of the most important varieties west of the Danube, but its population was severely decimated by phylloxera in the 1870s. Today, it is only cultivated in small stands on the north side of Lake Balaton and in the Somló area. This is mostly done in the vicinity of the all-female Kéknyelű grape variety for the purpose of fertilisation. The variety was a cross-breeding partner of the new variety Vulcanus. In 2016, an area under cultivation of six hectares was reported (Kym Anderson statistics).
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.Thomas Götz
