Old king hoarded wine bottles (5)
I believe the answer is:
edwin
'old king' is the definition.
(I've seen this before)
'hoarded wine bottles' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'EDWIN' is hidden in the letters of 'hoarded wine'.
(Other definitions for edwin that I've seen before include "Old king's" , "English king" , "and 19: Dickensian character" , "Fellow" , "C7 king of Northumbria" .)
