The Blauburger is the successful crossing of Blauer Portugieser x Blaufränkisch, created in Klosterneuburg by Professor Fritz Zweigelt. The idea was to plant the Blauburger in traditionally white wine regions, and where red wine varieties had problems ripening.
Parentage: New breed created by Dr. Fritz Zweigelt in 1923 at the Teaching and Research Centre for Viticulture and Horticulture (LFZ) in Klosterneuburg.
Vineyard area: Grows mainly in Niederösterreich, especially in the Weinviertel.
Important ampelographic features:
Leaf: five-lobed, overlapping petiole
Grape cluster: medium-sized; moderately compact; cylindrical, shouldered, often with wings; grapes have a frosted blueish-black colour
Ripening time: early- to mid-season
Significance, conditions: a salient feature is the deep dark colour of the wine, which makes Blauburger also a good blending partner for light-coloured red wines. While it can have a modest image as a single varietal wine, there is also a higher quality side, especially when the grapes are grown in good sites and yields are limited. Blauburger has no heavy site and soil demands.
Wine: The variety presents a wine that is extract-rich and has a very dark colour. Generally, the wines are neutral and have soft berry aromas - mostly elderberry. The palate is velvety and harmonious.
