The capital of Austria is also one of the nine federal provinces and, with around 1.9 million inhabitants, the most populous and, at 415 square kilometres, the largest city in the country. Until 1986, Wien was also the capital of Lower Austria, the largest province in the east, when it was replaced by St. Pölten. The city is crossed from north to south-east over a length of more than 20 kilometres by the Danube, on whose banks there are also other wine-growing areas in the country. With over 600 hectares of vineyards, Wien is the city with the largest wine production worldwide.
The fact that Wien and wine are inextricably linked is also manifested by the fact that the two words are formed from the same letters. In the Middle Ages, several German dialects (for example in the Lower Rhine) referred to the city as "Weyn". The well-known wine author Hugh Johnson writes that no city is as full of wine bliss as Wien . The Viennese Heuriger is known worldwide and many guests come to Wien(also) for this reason. In the 180 Heurigen establishments, the sale of high-quality bottled wines by the glass has also become established. Heurige can be found in Döbling (including Grinzing, Heiligenstadt, Neustift am Walde, Nußdorf, Sievering), Mauer, Oberlaa, Stammersdorf and Strebersdorf.
