Brought up the German wine (3)
I believe the answer is:
red
'wine' is the definition.
(red is a type of wine)
'brought up the german' is the wordplay.
'brought up' shows that the letters should be reversed in order (in a down clue, letters go up).
'the german' becomes 'der' ('the' in German).
'der' in reverse letter order is 'RED'.
(Other definitions for red that I've seen before include "River, its source in the US, flowing north to empty into L Winnipeg" , "Blushing" , "Ruby" , "Left-wing" , "Primary colour" .)
