Boyfriend with case of non-vintage wine (6)
I believe the answer is:
beaune
'vintage wine' is the definition.
'Beaune' can be an answer for 'wine' (I have seen 'French wine ' mean 'beaune' so perhaps 'wine' could also mean 'beaune'). I am unsure of the 'vintage' bit.
'boyfriend with case of non' is the wordplay.
'boyfriend' becomes 'beau' (synonyms).
'with' is a charade indicator (letters next to each other).
'case of' says to hollow out the word (remove centre letters) (like emptying a case).
'non' becomes 'negative' (similar in meaning).
'negative' with its centre taken out is 'ne'.
'beau'+'ne'='BEAUNE'
Can you help me to learn more?
(Other definitions for beaune that I've seen before include "French wine region" , "Red Burgundy wine" , "French wine centre" .)
