Wine expert, from art set, sozzled (6)
I believe the answer is:
taster
'wine expert' is the definition.
(I've seen this in another clue)
'art set sozzled' is the wordplay.
'sozzled' indicates an anagram.
'art'+'set'='artset'
'artset' anagrammed gives 'TASTER'.
'from' is the link.
(Other definitions for taster that I've seen before include "Food tester" , "Art set (anag.)" , "extract" , "A sample to try" , "One samples" .)
