Wine list section (4)
I believe the answer is:
reds
'wine list section' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for reds that I've seen before include "Colours for communists" , "Left-wingers" , "Tidies up" , "Scarlet communists" , "Scarlet and crimson, say" .)
