Pinch whiskey in wooden container (5)
I believe the answer is:
tweak
'pinch' is the definition.
(I know that tweak is a more specific form of the action pinch)
'whiskey in wooden container' is the wordplay.
'whiskey' becomes 'W' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' means one lot of letters goes inside another.
'wooden container' becomes 'teak' (I can't explain this - if you can you should give a lot more credence to this answer).
'w' inserted into 'teak' is 'TWEAK'.
(Other definitions for tweak that I've seen before include "Pinch sharply" , "Change slightly" , "Modify slightly" , "Twist; adjust finely" , "Adjust finely; pinch" .)
