Went back over hint, tucking into wine (8)
I believe the answer is:
retraced
'went back' is the definition.
(retracing is a kind of going back)
'hint tucking into wine' is the wordplay.
'hint' becomes 'trace' (synonyms).
'tucking into' means one lot of letters goes inside another.
'wine' becomes 'red' (red is a type of wine).
'trace' placed into 'red' is 'RETRACED'.
'over' acts as a link.
(Other definitions for retraced that I've seen before include "Followed back" , "Once more found" , "Discovered" .)
