Wine lovers will appreciate Vienna’s continuous effort to produce wine. There is no other city in the entire world that has more vineyards within its limits than the 1,700 acres the Austrian capital boasts. The Viennese produce around 660,000 gallons of white wine each year. That’s a lot of glasses to raise! The so-called wiener stands for “Viennese” in German. A Frankfurt-born butcher invented the sausage after he’d already moved to the Austrian capital. This fact explains the name Frankfurter, which is used in Vienna. In other countries, people refer to the dish as a Vienna sausage. Regardless of how you call it, you must try it.
