Wine doesn't start very well (4)
I believe the answer is:
okay
'very well' is the definition.
'wine doesn't start' is the wordplay.
'wine' becomes 'tokay' (Tokay is an example).
'doesn't start' means to remove the first letter.
'tokay' with its first letter removed is 'OKAY'.
(Other definitions for okay that I've seen before include "Approve, endorse" , "Alright" , "Not terrific but acceptable" , "Passable" , "Leave" .)
