Few large cities around the world count vineyards within their vicinity.
Vienna is one of them.
Most famous of their offerings is Wiener Gemischter Satz included in Slow Food 'Ark of Taste', slightly skunky according to Alice Feiring.
Austrian National Tourist Office notes:
"Many are surprised to learn that urban Vienna is also a wine region. But within the city limits, 320 winemakers tend 1,680 acres of grapes – mostly in the river-flanking areas of Nussberg, Kahlenberg, Bisamberg and Mauer."
5 wineries from Vienna banded together and formed WienWein to share their offerings with the world.
