Apple might make this drink excellent (6)
I believe the answer is:
laptop
'apple might make this' is the definition.
(Apple manufactures laptops)
'drink excellent' is the wordplay.
'drink' becomes 'lap' (to lap is to drink up).
'excellent' becomes 'top' (top can mean the best).
'lap'+'top'='LAPTOP'
(Other definitions for laptop that I've seen before include "Small computer" , "PC" , "Some work on this" , "Type of computer" , "Kind of computer" .)
