Austrian designation for a fresh white wine from the east of the Weinviertel wine-growing region (Lower Austria). The name is derived from the old trade route "Brünner Straße", which leads from Vienna to Brno (Czech Republic). Many winegrowing communities such as Kleinhadersdorf and Poysdorf are located along this present federal road 7. Due to the rather harsh climate they produce a typically acidic wine. In some cases this is used as a synonym for such a wine, regardless of its origin. However, the term does not mean "acidic" a priori and is not to be understood in a derogatory way.
