Amazing that any AG home brewer can follow this movie with total understanding. It illustrates just how ancient brewing is because many of the terms have come down to both languages virtually the same, I picked a couple up even though I don't know more than a bit of year 9 German from yonks ago:
Treber = trub
wurtze = wort
hopfenseiher - 'hop sieve' = hopback
Love those old wooden barrels and the spile hole/bung hole arrangement. I saw them in use in Austria in the late 70s but all gone now I guess.
