Bishop shoulders barrel we pour intermittently in boozer (7)
I believe the answer is:
brewpub
'bishop shoulders' is the definition.
I know nothing about this answer so I can't tell whether this works.
'barrel we pour intermittently in boozer' is the wordplay.
'intermittently' means one should take alternating letters.
'in boozer' becomes 'b' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'barrel'+'we'+'pour'='barrelwepour'
The alternating letters of 'barrelwepour' are 'brewpu'.
'brewpu'+'b'='BREWPUB'
Can you help me to learn more?
(Other definitions for brewpub that I've seen before include "Licensed premises where ale is made and sold" , "Self-sufficient local" , "specialist hostelry" , "Real ale maker and retailer" .)
