Drunken treats for wine expert? (6)
I believe the answer is:
taster
'wine expert?' is the definition.
(I've seen this in another clue)
'drunken treats' is the wordplay.
'drunken' indicates an anagram.
'treats' is an anagram of 'TASTER'.
'for' acts as a link.
(Other definitions for taster that I've seen before include "Sample intended to stimulate interest" , "person in charge of testing" , "Brief sample" , "Food tester" , "Sampler of food" .)
