Work out anagram to get cold drink (8)
I believe the answer is:
armagnac
'drink' is the definition.
(Armagnac is an example)
'work out anagram to get cold' is the wordplay.
'work out' indicates an anagram.
'to get' is a charade indicator (letters next to each other).
'cold' becomes 'c' (eg on taps).
'anagram' with letters rearranged gives 'armagna'.
'armagna'+'c'='ARMAGNAC'
(Other definitions for armagnac that I've seen before include "Spirit" , "A gram can for a French brandy" , "Dry brandy from south-west France" , "Brandy traditionally made in Aquitaine" , "stronger drink than ale" .)
