Blood — wine (6)
I believe the answer is:
claret
I believe this is a double definition.
'blood' is the first definition.
(claret can informally mean blood)
'wine' is the second definition.
(claret is a kind of wine)
(Other definitions for claret that I've seen before include "Cartel for Bordeaux red wine" , "Dark purplish-red colour" , "vessel might contain this?" , "in one's veins?" , "Purplish-red - blood" .)
