Enriched fruit drink, sophisticated sort (8)
I believe the answer is:
smoothie
I believe this clue is a double definition.
'enriched fruit drink' is the first definition.
(type of drink)
'sophisticated sort' is the second definition.
(a smooth person)
(Other definitions for smoothie that I've seen before include "Sweet talker" , "Drink of pureed fresh fruit with yoghurt or milk" , "Thick fruity drink - charmer" , "Smarmy type" , "Drink made with pureed fruit" .)
