Was there Muscadet? Six enticing bottles on the counter (7)
I believe the answer is:
existed
'was' is the definition.
(past tense of to be - to exist)
'there muscadet? six enticing bottles on the counter' is the wordplay.
'bottles' says the answer is hidden in the clue (bottling is a kind of containing).
'on the counter' says the letters should be written backwards (counter can mean in the opposite direction).
'detsixe' is hidden in the letters of 'there muscadet six enticing'.
'detsixe' in reverse letter order is 'EXISTED'.
(Another definition for existed that I've seen is " Lived".)
