Drink tea and euphoria doesn't end (7)
I believe the answer is:
chablis
'drink' is the definition.
(Chablis is an example)
'tea and euphoria doesn't end' is the wordplay.
I cannot quite see how this works, but
'tea' could be 'cha' (cha is a type of tea) and 'cha' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for chablis that I've seen before include "French dry white wine" , "Dry white Burgundy" , "Burgundy town and white wine" , "Drink" , "Town in north central France noted for white Burgundy wines" .)
