For the benefit of Japanese drinkers? (4)
I believe the answer is:
sake
'for the benefit' is the definition.
(sake is a kind of benefit)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for sake that I've seen before include "Benefit - behalf" , "Japanese alcoholic drink made from rice" , "Jap. alcoholic drink from rice; for Pete's -" , "Japanese spirit made from rice" , "For old times' --" .)
