Sort of coffee, say: one loves drinking it (7)
I believe the answer is:
philtre
'one loves drinking it' is the definition.
(philtre means a love potion)
'sort of coffee say' is the wordplay.
'sort of coffee' becomes 'filter' (filter coffee is a type of coffee).
'say' indicates a 'sounds like' (homophone) clue.
'filter' sounds like 'PHILTRE'.
(Other definitions for philtre that I've seen before include "Love-potion" , "Exciting drink" , "It makes you love" , "Magic love potion" .)
