Blend a lot of wine, enthralled by approach (7)
I believe the answer is:
combine
'blend' is the definition.
(I know that blend can be written as combine)
'a lot of wine enthralled by approach' is the wordplay.
'a lot of wine' becomes 'bin' (bin can mean a container for wine).
'enthralled by' indicates putting letters inside ('enthral' can mean 'capture').
'approach' becomes 'come' (e.g. as imperative).
'bin' going within 'come' is 'COMBINE'.
(Other definitions for combine that I've seen before include "Blend" , "Unite; some farm machinery" , "alloy" , "Join together" , "Mix together into one" .)
