Squandered contents of table wine (4)
I believe the answer is:
blew
'squandered' is the definition.
('blow' can be a synonym of 'squander')
'contents of table wine' is the wordplay.
'contents of' says the answer is hidden in the clue.
'BLEW' is hidden within 'table wine'.
(Other definitions for blew that I've seen before include "Squander in the past" , "Gusted" , "Breathed hard" , "Bungled (an opportunity)" , "Spent recklessly; exploded suddenly" .)
