Warmed up, he put away wine bottles (8)

I believe the answer is:

reheated

'warmed up' is the definition.

'he put away wine bottles' is the wordplay.
'put away' becomes 'ate' (I've seen this in other clues).
'wine' becomes 'red' (red wine is an example).
'bottles' is an insertion indicator ('bottle' can mean to contain).
'he'+'ate'='heate'
'heate' put within 'red' is 'REHEATED'.
