Joy mostly associated with tea and wine (7)
I believe the answer is:
chablis
'wine' is the definition.
(Chablis is an example)
'joy mostly associated with tea' is the wordplay.
'joy' becomes 'bliss' (I've seen this before).
'mostly' means to remove the last letter.
'associated with' means one lot of letters go next to another.
'tea' becomes 'cha' (cha is a type of tea).
'bliss' with its last letter removed is 'blis'.
'blis' after 'cha' is 'CHABLIS'.
'and' is the link.
(Other definitions for chablis that I've seen before include "French dry white wine" , "Burgundy town and white wine" , "Classic white wine from Burgundy" , "Dry Burgundy wine" , "Dry white Burgundy" .)
