Crush the spirit (6)
I believe the answer is:
scotch
This clue is a double definition.
'crush' is the first definition.
(I've seen this before)
'the spirit' is the second definition.

(Other definitions for scotch that I've seen before include "See 1" , "Decisively put an end to" , "Prevent -- frustrate" , "Frustrate - whisky" , "Kind of whisky spelt thus" .)
