Distilled wine or fermented fruit juice (6)
I believe the answer is:
brandy
'distilled wine or fermented fruit juice' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for brandy that I've seen before include "- - -snap" , "Of a legal entity acting as an individual" , "How to get a drink" , "eg Armagnac" , "Distilled alcohol" .)
