Red Bordeaux wine (6)
I believe the answer is:
claret
'red bordeaux wine' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for claret that I've seen before include "in one's veins?" , "Dry red wine of Bordeaux" , "Deep purplish colour" , "Alcohol" , "Red Bourdeaux wine" .)
