Brewed ale: demon drink (8)
I believe the answer is:
lemonade
'drink' is the definition.
(I know that lemonade is a type of fruit drink)
'brewed ale demon' is the wordplay.
'brewed' indicates anagramming the letters.
'ale'+'demon'='aledemon'
'aledemon' is an anagram of 'LEMONADE'.
(Other definitions for lemonade that I've seen before include "This should refresh" , "Flavoured mineral drink" , "Mo leaned on the drink" , "Fizzy pop" , "Still or fizzy drink" .)
