Cartel spilt drink (6)
I believe the answer is:
claret
'drink' is the definition.
(claret is a kind of drink)
'cartel spilt' is the wordplay.
'spilt' indicates an anagram.
'cartel' with letters rearranged gives 'CLARET'.
(Other definitions for claret that I've seen before include "Dark red Bordeaux wine" , "Purplish-red - blood" , "Red wine from southern France" , "Shade of red" , "Dry red wine of Bordeaux" .)
