Bar refuses to provide bottles (5)
I believe the answer is:
estop
'bar' is the definition.
(thesaurus)
'refuses to provide bottles' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'ESTOP' is hidden in the letters of 'refuses to provide'.
(Other definitions for estop that I've seen before include "Bar, for a lawyer" , "Legally check" , "Legally prevent" , "term in law" , "lawyer's bar" .)
