The sack around tavern is stored like wine (6)
I believe the answer is:
Here is my best explanation:
'stored like wine' is the definition.
(wine may be stored in a wine bin)
'the sack around tavern' is the subsidiary indication.
'the sack' becomes 'bed' ('in the sack' means 'in bed').
'around' is an insertion indicator.
'tavern' becomes 'inn' (I've seen this before).
'bed' enclosing 'inn' is 'binned'.
'is' is the link.
(Another definition for binned that I've seen is "Discarded".)
