One who conveys news about alcoholic drink (8)
I believe the answer is:
reporter
'one who conveys news' is the definition.
'about alcoholic drink' is the wordplay.
'about' becomes 're' (regarding**).
'alcoholic drink' becomes 'porter' (I've seen this before).
're'+'porter'='REPORTER'
(Other definitions for reporter that I've seen before include "One gives us the news" , "hacker?" , "Newshound" , "Newspaper correspondent, journalist" , "Newspaper worker" .)
