Drink alcohol a German provides (5)
I believe the answer is:
lager
'drink' is the definition.
(lager is a kind of drink)
'alcohol a german provides' is the wordplay.
'provides' indicates a hidden word.
'LAGER' is hidden in the letters of 'alcohol a german'.
(Other definitions for lager that I've seen before include "Regal kind of beer" , "Light beer needed" , "drink in the bar?" , "Regal sort of beer" , "Regal (anag) - drink" .)
