Wine or tea taken with endless bliss (7)
I believe the answer is:
chablis
'wine' is the definition.
(Chablis is an example)
'tea taken with endless bliss' is the wordplay.
'tea' becomes 'cha' (cha is a type of tea).
'taken with' is a charade indicator (letters next to each other).
'endless' means to remove the last letter.
'bliss' with its last letter taken off is 'blis'.
'cha'+'blis'='CHABLIS'
'or' is the link.
(Other definitions for chablis that I've seen before include "Drink" , "French dry white wine" , "Classic white wine from Burgundy" , "Dry white Burgundy" , "Dry Burgundy wine" .)
