Trento in Italy has a lot of German influence and especially when it comes to food and beer. They even serve their versions of German Weizenbier. see http://en.wikipedia.org/wiki/Trentino and http://www.tripadvisor.co.uk/Restaurants-g1493737-c21-Province_of_Trento_Trentino_Alto_Adige.html
Why is that so? Does anyone know whether there is a difference between Trento's German style beers and German German style beers?
