Beer steins (4)
I believe the answer is:
mugs
'beer steins' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mugs that I've seen before include "Gullible people" , "Drinking cups" , "Cups without saucers" , "'Cups, faces and fall guys (4)'" , "Fools - faces" .)
