"Unser Bier ist alle."

[fagbot]

I thought it meant "our beer is everything (to us)" ...

[christian]

That would be something along the lines of "Unser Bier bedeutet uns alles".

[ryantaylor]

I have no idea why I typed "Our beer is all". That doesn't even make sense.

[eschlange]

I did it too... because some sentences don't make sense and because I only knew 'alle' as all.

[givello]

Uh, "empty" is not in the hover list for beer...

[Ajna]

Oh, losing a heart to a slang expression I couldn't have figured out on my own.

Nice didactic touch, duo...

[Bikebreaker]

Lol. Oh well, you WILL remember this idiom now...

[Bikebreaker]

Seems to be an idiom. "alle" does not seem to mean "empty" otherwise.

[Lenkvist]

It is still not a good translation, it should be "gone".

[VirgilJSchmidt]

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?

[Duomail]

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.

[christian]

A more idiomatic translation would be "We're out of beer".

[Kareee417]

why empty??? empty means: leer

[S.P.Abrams]

lol, It's same in Russian) The word "all" in slang means "the end". Actually it has an analogue in English: "That's all. We are going home".
Hope this helps
