Hot winter drink (5)
I believe the answer is:
cocoa
'hot winter drink' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cocoa that I've seen before include "Lightish brown colour of a drink" , "Powder from cacao beans" , "Chocolatey drink" , "Chocolate-like drink" , "Bean used in making chocolate" .)
