Winter apple (6)
I believe the answer is:
russet
'winter apple' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for russet that I've seen before include "Autumnal red as of leaves" , "Autumnal reddish-brown colour" , "Brown with a reddish tinge" , "browny-red" , "Autumnal reddish brown" .)
