Breaking ice with him: full bar providing drink (13)
I believe the answer is:
liebfraumilch
'drink' is the definition.
(liebfraumilch is a kind of drink)
'breaking ice with him full bar' is the wordplay.
'breaking' is an anagram indicator.
'with' says to put letters next to each other.
'ice'+'him'+'full'+'bar'='icehimfullbar'
'icehimfullbar' anagrammed gives 'LIEBFRAUMILCH'.
'providing' acts as a link.
(Other definitions for liebfraumilch that I've seen before include "Cheap blended Rhine wine for the export market" , "German white wine" , "Cheapish white wine from the Rhine region" , "Light white Rhine wine" .)
