Heartless Harry's up for wine (5)
I believe the answer is:
syrah
'for wine' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for syrah that I've seen before include "Red grape variety" , "Dark-skinned red wine grape" , "Grape variety (Shiraz)" , "Black grape variety" .)
