The white grape variety is a new breed between Frühroter Veltliner x Gray Portuguese, Synonyms are Cvai Gold, Jubilejni, Jubilens Rebe, Jubileumsrebe and Klosterneuburg 24-125. The right parenthood only came about in 1998 DNA analysis out because until then it was erroneously Blue Portuguese x Blaufränkisch accepted. The crossing took place in 1922 on Klosterneuburg Wine Institute in Lower Austria by Dr. Fritz Zweigelt (1888-1964). The vine was presented to the public in 1960 on the occasion of this institute's centenary, and the name is derived from this anniversary. The medium to late ripening vine is resistant to Botrytis, It produces rather neutral, low-acid white wines that are used for sweet wines. The variety is grown exclusively in Austria grown. In 2009, 13 hectares were registered with a downward trend; thereof 9 in Burgenland (ten years earlier there were 30).
