Fermented honey beverage (4)
I believe the answer is:
mead
'fermented honey beverage' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mead that I've seen before include "Alcohol" , "Alcoholic drink made with honey" , "Honey-based alcoholic drink" , "something to drink" , "Alcoholic drink of fermented honey and water of old" .)
