Inexperienced crew denied last drink (5,3)
I believe the answer is:
green tea
'drink' is the definition.
(type of tea)
'inexperienced crew denied last' is the wordplay.
'inexperienced' becomes 'green' (similar in meaning).
'crew' becomes 'team' (I've seen this in another clue).
'denied last' means to remove the last letter (the word is denied its last letter).
'team' with its last letter taken off is 'tea'.
'green'+'tea'='GREEN TEA'
(Other definitions for green tea that I've seen before include "'Asian herbal drink (5,3)'" , "Oriental leaves" , "Brewed" , "Beverage" , "Food at the golf club" .)
