Warmer vessel spinning on wheel (6)
I believe the answer is:
cognac
'warmer' is the definition.
(I've seen this before)
'vessel spinning on wheel' is the wordplay.
'vessel' becomes 'can' (type of container).
'spinning' is a reversal indicator.
'on' is a charade indicator (letters next to each other).
'wheel' becomes 'cog' (wheel with teeth in a machine).
'can' written backwards gives 'nac'.
'nac' put after 'cog' is 'COGNAC'.
(Other definitions for cognac that I've seen before include "High quality brandy" , "Brandy of the French Charente" , "Good brandy" , "(French district famed for) fine brandy" , "Type of brandy" .)
