The Jubiläumsrebe (literally Centenary vine) is a new crossing created by Professor Zweigelt in 1922. The variety derives from Grey Portugieser x Frühroter Veltliner, and is only cultivated in minute quantities. In optimal conditions, it achieves very high sugars and a high must weight, without noble rot, when dried.

New breed created by Dr. Fritz Zweigelt in 1922 at the Teaching and Research Centre for Viticulture and Horticulture (LFZ) in Klosterneuburg. The variety made its public debut at the 100th anniversary celebration for the founding of the viticulture school Höheren Bundeslehr- und Versuchsanstalt für Wein- und Obstbau, Klosterneuburg. The variety's name commemorates the occasion.
Because there are several other varieties used for vinifying excellent Prädikat wines, this new breed never gained significance.
Significance & conditions
The variety is cultivated best to achieve low yields. In good sites, the grapes reach high sugar levels. High must weights are possible even through the drying of non-botrytised grapes. Has few soil demands.
