Soft drink containing spirits (7)
I believe the answer is:
alcopop
'soft drink containing spirits' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for alcopop that I've seen before include "Sweet pub drink" , "Liquor drink for kids" , "Mixed drink" , "Intoxicating beverage tasting like a soft drink" , "Intoxicating drink aimed at the younger market" .)
