Spoil a good drink? (6)
I believe the answer is:
scotch
This clue could be a double definition.
'spoil a good' is the first definition.
'scotch' can be an answer for 'spoil' (synonyms). I am unsure of the 'a good' bit.
'drink?' is the second definition.
(Scotch is an example)
Can you help me to learn more?
(Other definitions for scotch that I've seen before include "Type of egg" , "providing nursery facility in school" , "Decisively put an end to" , "liquor" , "Frustrate; quash" .)
