Wine; pawn (4)
I believe the answer is:
hock
This clue is a double definition.
'wine' is the first definition.
(I know that hock is a type of white wine)
'pawn' is the second definition.
(hock can mean to pawn an item at a pawnbroker's)
(Other definitions for hock that I've seen before include "Deposit with a pawnbroker" , "Buy property, say" , "Rhine wine -- horse joint" , "Uncle's pledge" , "Hamstring" .)
