i currently live in Germany and I would like to buy one of these fancy racking canes that could be seen in homebrew YT videoes. The problem is i don'y know the name for that and I hope that native german speaker or somebody else can tell me that.
I guarantee that the Germans have a specific compound word for it (which I don't know), but you can probably safely try "Bier Siphon". Not a perfect match, but if you find the siphons you'll find the racking canes! It's also easy to remember!
from what i can see "bierheber" is what is used online for an auto-siphon. it essentially means "beer lifter" when directly translated, however siphon is used in the form of "siphonpumpe" which is used more for the auto industry.
