Association distributing claret (6)
I believe the answer is:
cartel
'association' is the definition.
(I know that cartel is a type of consortium)
'distributing claret' is the wordplay.
'distributing' indicates an anagram.
'claret' with letters rearranged gives 'CARTEL'.
(Other definitions for cartel that I've seen before include "Protective trade ring for claret" , "Conspiracy of businesses" , "Anti-competitive group for claret" , "Protective trade group for claret" , "Business monopoly for claret" .)
