The Austrian federal state located in the far west of the country is one of the smallest wine-growing regions in Austria (along with Carinthia, Upper Austria, Salzburg and Tyrol). This designation applies to regional wines, quality wines may be marketed under "Weinbaugebiet Vorarlberg". Once there were around 500 hectares of vineyards here, mainly in the Walgau and Rhine Valley. Due to phylloxera and the competition of South Tyrolean wine after the construction of the Arlberg railway, the vines almost completely disappeared except for one vineyard in Röthis. Today they cover 10 hectares, the "Association of Wine Growers of Vorarlberg" consists of 70 members. Cultivated are the white wine varieties Müller-Thurgau, Riesling, Chardonnay,Pinot Blanc and Traminer as well as the red wine varietiesPinot Noir, BlaufränkischCabernet Sauvignon and Merlot. Well-known wineries include Franz Nachbaur in Röthis, Peter Summer in Frastanz and Josef Möth with Austria's westernmost Heurigen.
The winegrower Josef Möth cultivates 3.5 hectares of vineyards on Lake Constance. In May 2919 he started an interesting project. Two tanks, each containing 1,000 litres of white wine and red wine, were sunk 60 metres deep into Lake Constance. The white wine was to spend half a year in the lake, the red wine a whole year. The aim is to find out how the uniform temperature of 4 °Celsius, the dark light conditions and the high water pressure affect the taste and quality. The wines will be marketed as "Edition Tiefenrausch". The project is supported by the Klosterneuburger Weinbauinstitut (HBLA for fruit and viticulture). Similar projects have already been carried out on Lake Neusiedl and in the sea.
