Drink wine in comfort (7)
I believe the answer is:
support
'comfort' is the definition.
(I've seen this before)
'drink wine' is the wordplay.
'drink' becomes 'sup' (I've seen this before**).
'wine' becomes 'port' (port is a kind of wine).
'sup'+'port'='SUPPORT'
'in' is the link.
(Other definitions for support that I've seen before include "Provide financial backing or bolster" , "Help; bear" , "Give assistance to" , "Buttress" , "used to give strength?" .)
