Kept in the cellar, perhaps (4)
I believe the answer is:
aged
'kept in the cellar perhaps' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aged that I've seen before include "Getting on" , "Elderly" , "not a modern copy" , "Matured like wine in wood" , "not like a callow youth" .)
