This coffee has surprisingly nice aroma (9)
I believe the answer is:
americano
'this coffee' is the definition.
(type of coffee)
'surprisingly nice aroma' is the wordplay.
'surprisingly' indicates an anagram (a surprising ordering of the letters).
'nice'+'aroma'='nicearoma'
'nicearoma' is an anagram of 'AMERICANO'.
'has' acts as a link.
(Other definitions for americano that I've seen before include "Style of coffee" , "Espresso diluted with hot water" , "drink" .)
