Bring back the German wine (3)
I believe the answer is:
red
'wine' is the definition.
(red is a type of wine)
'bring back the german' is the wordplay.
'bring back' is a reversal indicator.
'the german' becomes 'der' ('the' in German).
'der' written backwards gives 'RED'.
(Other definitions for red that I've seen before include "Flushed" , "Primary colour" , "Bordeaux claret, for instance" , "Colour of a cardinal's hat" , "Colour of blood" .)
