Joint for wine (4)
I believe the answer is:
hock
This clue is a double definition.
'joint' is the first definition.
(joint of meat)
'wine' is the second definition.
(hock is a kind of wine)
'for' is the link.
(Other definitions for hock that I've seen before include "Pawn a German wine?" , "White wine and horse's joint" , "to leave with uncle" , "Hamstring" , "White Rhine wine" .)
