Coffee giving out nice aroma (9)
I believe the answer is:
americano
'coffee' is the definition.
(I've seen this before)
'out nice aroma' is the wordplay.
'out' is an anagram indicator.
'nice'+'aroma'='nicearoma'
'nicearoma' anagrammed gives 'AMERICANO'.
'giving' acts as a link.
(Other definitions for americano that I've seen before include "Style of coffee" , "Espresso diluted with hot water" , "drink" .)
