Stuttgart? I haven't been there, is it any good?
I've only been to Koln, Berlin and Munich (was going to 'pop in' from time to time during 2 years stay in the UK that didn't really happen).
I'm not rich enough to sponsor people a trip to Munich!
I'll try to go to Dan Murphys or Acland Cellars to see if there's European beers I recgonise from my recent trip.
Tein (if sold from Fulcurm Suspensions) springs to mind, as for others, I don't have the clue.
EDIT: If brought from Japan and doesn't have ADR something, it's illegal as far as I understand.
