"Unser Bier ist alle."
That would be something along the lines of "Unser Bier bedeutet uns alles".
I have no idea why I typed "Our beer is all". That doesn't even make sense.
I did it too... because some sentences don't make sense and because I only knew 'alle' as all.
Oh, losing a heart to a slang expression I couldn't have figured out on my own.
Nice didactic touch, duo...
This may be an idiom, and when one is just learning the language or a certain part of the language, throwing a curve ball like that, though will now stick, is really not as helpful as it may thought to have been. Why not create a section called idioms?
what other cases is it used for?
I guess it is at least for all type of drinks so in servings as in bottles/containers.
