Bottle broken by the RAF ace (6)
I believe the answer is:
carafe
'bottle' is the definition.
(I know that carafe is a type of bottle)
'broken by the raf ace' is the wordplay.
'broken by' indicates an anagram (a broken form of the letters).
'raf'+'ace'='raface'
'raface' with letters rearranged gives 'CARAFE'.
(Other definitions for carafe that I've seen before include "Glass flask for serving wine" , "Wine-flask" , "Glass bottle in which wine is served at table" , "Decanter" , "Wine is decanted into it" .)
