The German turned up for wine (3)
I believe the answer is:
red
'wine' is the definition.
(red wine is a kind of wine)
'the german turned up' is the wordplay.
'the german' becomes 'der' ('the' in German).
'turned up' is a reversal indicator.
'der' reversed gives 'RED'.
'for' is the link.
(Other definitions for red that I've seen before include "Left-wing" , "- - poker: Kniphofia" , "See it and become angry" , "Blood-coloured" , "A colourful communist" .)
