Somewhat better alcohol to be served up (6)
I believe the answer is:
claret
'somewhat better alcohol to be served up' is the definition.
I can't judge whether this defines the answer.
'somewhat better alcohol to be served up' is the wordplay.
'somewhat' indicates a hidden word.
'to be served up' shows that the letters should be reversed in order.
'teralc' is hidden within 'better alcohol'.
'teralc' back-to-front is 'CLARET'.
(Other definitions for claret that I've seen before include "Purplish-red - blood" , "Wine from the Bordeaux region" , "Deep purplish colour" , "Dark purplish-red colour" , "in one's veins?" .)
