Fermented rice drink (4)
I believe the answer is:
sake
'fermented rice drink' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sake that I've seen before include "account" , "Japanese alcoholic drink make from rice" , "Benefit - Japanese drink" , "'Reason, purpose (4)'" , "Japanese spirit made from rice" .)
