Coffee wafting nice aroma (9)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
americano
'coffee' is the definition.
(I've seen this before)
'wafting nice aroma' is the wordplay.
'wafting' indicates an anagram.
'nice'+'aroma'='nicearoma'
'nicearoma' anagrammed gives 'AMERICANO'.
(Other definitions for americano that I've seen before include "Espresso diluted with hot water" , "Style of coffee" , "drink" .)
