Pass drinks, contents of beer bottle (6)
I believe the answer is:
elapse
'pass' is the definition.
(synonyms)
'drinks contents of beer bottle' is the wordplay.
'drinks' becomes 'brews' (brew is a kind of drink).
'contents of' means to look at the middle letters (I've seen 'content' mean this).
'beer bottle' becomes 'lapse' (I can't explain this - if you can you should give a lot more credence to this answer).
The middle of 'brews' is 'e'.
'e'+'lapse'='ELAPSE'
Can you help me to learn more?
(Other definitions for elapse that I've seen before include "Go past" , "Please (anag) -- pass away" , "Pass or expire - please" , "Glide by" , "'Pass by, as time (6)'" .)
