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.

Significance & conditions
One distinctive feature is the deep, dark colour of the wine, which also makes Blauburger a good blending partner for pale-coloured red varieties. While it can have a mediocre image as a monovarietal wine, it can really come into its own when grown in the right vineyard and the volume of fruit is restricted. Blauburger is not a demanding variety in terms of location or soil.
