Bamberg, the city of rauchbier. But more importantly, the city with probably the biggest specialty malts house over the world. I will come back to malt houses later.
It’s fascinating to see that Germany has a very extensive beer culture with a whole set of customs, behaviours and rituals. For tourists it might be confusing, as waiters/waitresses will seem quite curtly a lot of the time, until you adhere to the customs or are in any other way found okay, then nothing is too much.
