Freezing ale (6)
I believe the answer is:
bitter
I believe this is a double definition.
'freezing' is the first definition.
(thesaurus)
'ale' is the second definition.

(Other definitions for bitter that I've seen before include "Intensely cold, beer" , "Resentful, being piercingly cold" , "Sour like some English beer" , "English beer, sounds sour" , "Acerbic" .)
