One producing beer outside of Renfrew in new way? (6)
I believe the answer is:
brewer
'one producing beer outside of renfrew in new way?' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition. I also know that 'beer' relates to this answer.
'beer outside of renfrew in new way?' is the wordplay.
'outside of' says to hollow out the word (remove centre letters).
'in new way?' indicates an anagram.
'renfrew' with its middle removed is 'rw'.
'beer'+'rw'='beerrw'
'beerrw' is an anagram of 'BREWER'.
(Other definitions for brewer that I've seen before include "Tendency to seek perfection" , "who offers booze?" , "Beer manufacturer" , "Reference" , "Bitter maker?" .)
