We bring potty for making beer (7)
I believe the answer is:
'making beer' is the definition.
(I've seen this before)
'we bring potty' is the wordplay.
'potty' indicates an anagram.
'webring' is an anagram of 'BREWING'.
'for' acts as a link.
(Other definitions for brewing that I've seen before include "Making beer" , "drink in one go" , "Making tea" .)
