Cartel transporting alcohol (6)
I believe the answer is:
claret
'alcohol' is the definition.
(claret is a kind of alcohol)
'cartel transporting' is the wordplay.
'transporting' indicates anagramming the letters (I've seen 'transported' mean this).
'cartel' anagrammed gives 'CLARET'.
(Other definitions for claret that I've seen before include "Wine from the Bordeaux region" , "in one's veins?" , "Alcohol" , "Red wine from southern France" , "Dark purplish-red colour" .)
