Light-bodied beer (5)
I believe the answer is:
lager
'light-bodied beer' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for lager that I've seen before include "Regal (anag) - drink" , "Effervescent beer" , "Drink - 5 down (anag)" , "Local offering" , "Light-bodied beer" .)
