Instinct to pry into wine quality (4)
I believe the answer is:
nose
I believe this is a triple definition!
'instinct' is the first definition.
(a nose for something is a good instinct for it)
'to pry' is the second definition.
(synonyms)
'into' is a link.
'wine quality' is the third definition.
(I've seen this in another clue)
(Other definitions for nose that I've seen before include "Conk (slang)" , "See 7" , "Faculty for detecting" , "Olafactory organ" , "Don't cut this off to spite your face" .)
