The white grape variety originates from Austria. Synonyms are Blanke, Fuchsbraune, Kahlenberger Weiße, Weiße (Austria); Austriai, Ausztriai, Ausztriai Fehér, Osztrak Fehér, Widenska (Hungary). It must not be confused with the varieties Braunweißer Veltliner or Silvaner, despite seemingly suggestive synonyms or morphological similarities. According to DNA analyses carried out in 1999, it is a presumably natural cross between Weißer Heunisch (Gouais Blanc) x unknown variety. The variety is a parent of Silvaner. The vine is resistant to various vine diseases. It produces yellow-green, strong and acid accentuated white wines. The variety was very widespread at the beginning of the 19th century in the wine villages around the Vienna Kahlenberg in Grinzing, Heiligenstadt, Klosterneuburg, Nußdorf (Nußberg) and Weidling. It established the good reputation of the popular Heurigen wine "Grinzinger" (up to 90% Austrian White, the rest Traminer). The vine is no longer in the catalogue of varieties, but may be cultivated on existing areas. For example, it is cultivated by the organic winery Alois Raubal in Gumpoldskirchen (Lower Austria). The vine museum of the Franz Leth winery in Fels am W. also has a few vines. No stocks were reported in 2016 (Kym Anderson statistics).
In the past, you needed a wealth of encyclopaedias and specialist literature to keep up to date in your vinophile professional life. Today, Wine lexicon from wein.plus is one of my best helpers and can rightly be called the "bible of wine knowledge".
