Some Russians' wines? (4)
I believe the answer is:
reds
I believe this clue is a double definition.
'some russians'' is the first definition.
(I've seen this in another clue)
'wines?' is the second definition.
(wine is a kind of red)
(Other definitions for reds that I've seen before include "Colours for communists" , "Left-wingers" , "Scarlet communists" , "Tidies up" , "Colourful communists" .)
