Flensburger Pilsner, one of the few beers left with the nowadays iconic shackle lock. My number one.
Can also be seen here in numerous scenes... if you look very closely:
For non-alcoholic beer, Krombacher Alkoholfrei tastes fine. Just a hair away from its alcoholic variant.
I tried some Belgian beers in the past, but due to their nature, you drink them more like wine.
Bavarian wheat beers fill up your stomach quickly like they're still fermenting, so drink with caution.
Some restaurants where I live serve Japanese beer like Kirin, Asahi and Sapporo. Some are more bitter, some less.
