The main grape variety is the Grüner Veltliner, followed by Neuburger, Traminer, Weissburgunder, Chardonnay and Riesling. Reds, such as Blauburger, Zweigelt, Portugieser and Cabernet Sauvignon, while few in numbers, are no less delightful.
The wine-growing areas of Vienna are probably as old as the city itself. When Vienna was the Celtic village of Vedunia and the Roman military port of Vindobona, a wine culture already existed. However, the oldest Viennese vineyards weren't documented before 1132. By the late Middle Ages, vineyards were thriving throughout all parts of the city.
Today's "Heurige" culture, which goes back to the time of Charlemagne, was actually recognised officially by Emperor Josef II in 1784. He decreed that wine-makers could, when selling their own wines, set their own wine bar prices as well as offer food that they produce themselves. Growing urbanisation saw the decline of the Heurige, until the recultivation of grapes helped bring about its resurgence.
There are now approximately 180 licensed Heurige and 497 wine-makers in Vienna. Many of these wine-makers are opening their bottled wines and serving them by the glass - often a Riedel glass. Especially because Riedel is now producing a new line of wine glasses, Vienna Classic, which have been designed by Viennese wine-makers themselves. The best-known wine districts of Vienna are Heiligenstadt (Kahlenberg and Nussberg), Nussdorf, Sievering, Neustift am Walde and, of course, Grinzing. There are also wineyards in Ottakring, Mauer and Oberlaa. The wines from the Bisamberg are offered in Stammersdorf, Strebersdorf and Jederlersdorf.
