I will resume here what I know about this topic.
One of the twenty regions of Italy, and one of the most northern, is Trentino-Alto Adige. It borders with Austria and, for some 20km, with Switzerland. Trentino-Alto Adige is divided in two provinces: province of Trento (Trentino, capital town Trento) and province of Bolzano/Bozen (Alto Adige/Südtirol, capital town Bolzano/Bozen). The latter is more northern than the former and is the proper bilingual area on that side (German and Italian are the two most spoken languages). Bolzano/Bozen is the most populated city council in its province and, curiously, the one with the highest rate of native Italian speakers. Unfortunately I can't reference this statistic that I heard in the years I was used to visit those places often.
Roughly speaking, the German or Austrian influence on culture and food and drinks is positively evident all around the region, becoming milder moving north to south.
Several Austrian and German beers are popular here: Stiegl, Spaten, Maisel's and many more. The interesting point about beers, but not unexpected: beverages from several foreigner brands and companies are distributed but also produced in Italy. While I was searching for the linked reference, that seems to agree, I was sure to remember that Weihenstephan, one of my favourite beers back to those mountains, was produced and bottled either in Germany or in Italy at the Forst brewery in Lagundo, in Alto Adige/Südtirol.
