Wine drunk neat, sure! (8)
I believe the answer is:
sauterne
'wine' is the definition.
(Sauterne is an example)
'drunk neat sure' is the wordplay.
'drunk' is an anagram indicator.
'neat'+'sure'='neatsure'
'neatsure' is an anagram of 'SAUTERNE'.
(Other definitions for sauterne that I've seen before include "Golden dessert wine, US style" , "Sweet white dessert wine" , "drink" , "Sweet French white wine" , "Sweet white wine from around Bordeaux" .)
