Back when I was working, we had a German co-worker come over to the states to visit us. We took him to a local bar and during that time we talked about Octoberfest and how much beer the Germans drank during it. He told us the reason they were able to drink so much is their beer wasn't as strong as ours. He didn't appear to be joking or so maybe it was just the beer they serve during Octoberfest?
BTW, I've never been to Germany or Europe so I wouldn't know.
