Wine with tea, not quite the greatest joy (7)
I believe the answer is:
chablis
'wine' is the definition.
(Chablis is an example)
'with tea not quite the greatest joy' is the wordplay.
'with' is a charade indicator (letters next to each other).
'tea' becomes 'cha' (cha is a type of tea).
'not quite' means to remove the last letter.
'the greatest joy' becomes 'bliss'.
'bliss' with its final letter taken off is 'blis'.
'cha'+'blis' is 'CHABLIS'.
(Other definitions for chablis that I've seen before include "Dry Burgundy wine" , "Classic white wine from Burgundy" , "French dry white wine" , "Burgundy town and white wine" , "French town noted for white Burgundy wines" .)
