Remedy, golden beer bottles (4,3)
I believe the answer is:
sort out
'remedy' is the definition.
(remedy can mean to fix or sort out)
'golden beer bottles' is the wordplay.
'golden' becomes 'or'.
'beer' becomes 'stout' (I've seen this before).
'bottles' means one lot of letters goes inside another (bottle can mean to contain).
'or' inserted inside 'stout' is 'SORT OUT'.
(Other definitions for sort out that I've seen before include "Resolve - to put in order" , "Arrange" , "Select from others or informally punish" , "Segregate and put in order" , "handle" .)
