A capital Italian perfume (5)

I believe the answer is:

aroma

I'm a little stuck... Click here to teach me more about this clue!

'italian perfume' is the definition.
'aroma' can be an answer for 'perfume' (synonyms). I'm not certain of the 'italian' bit.

'a capital' is the wordplay.
'capital' becomes 'roma' (Roma is an example).
'a'+'roma'='AROMA'

Can you help me to learn more?

(Other definitions for aroma that I've seen before include "Strong smell" , "Pervasive quality" , "Scent - fragrance" , "A pleasant smell as of food" , "Spicy fragrance" .)

I've seen this clue in the Evening Standard.
