Drunk son serving wine bottles (9)
I believe the answer is:
plastered
'drunk' is the definition.
(I've seen this before)
'son serving wine bottles' is the wordplay.
'son' becomes 's'.
'serving' becomes 'plate'.
'wine' becomes 'red' (red wine is an example).
'bottles' means one lot of letters goes inside another ('bottle' can mean to contain).
'plate'+'red'='platered'
's' inserted into 'platered' is 'PLASTERED'.
(Other definitions for plastered that I've seen before include "under the table?" , "get soaked?" , "spread" , "Drunk (as a ceiling or wall may be)" , "incapable" .)
