Wine from Corso Avenue (5)
I believe the answer is:
soave
'wine' is the definition.
(Soave is an example)
'from corso avenue' is the wordplay.
'from' says the answer is hidden in the clue.
'SOAVE' is hidden within 'corso avenue'.
(Other definitions for soave that I've seen before include "Italian dry white wine" , "Dry white wine from Verona" , "Italian wine region" , "Drink" , "White wine from NE Italy" .)
