hi dirk, my nameis mut, im michaels instructor in the uk,the word humpenstufen, well here goes. a large part of our organization is in germany, and every year we travel to various parts of germany to train, we all here the germans speak but being dumb english we never learn it enough to speak it, so one day whilst in a bavarian bar somewhere a friend of mine steve said i could just do with a humpenstufen,,,i laughed and said you mean hefe weissen, he said yes.we then told all our german friends this, they laughed and so the word was born, since then it has grown into a greeting and also a ki expression and also the one international word that means everything..i hope this helps.....
