Cured itch in a wine from Italy (7)
I believe the answer is:
chianti
'wine from italy' is the definition.
(Chianti is an Italian wine)
'cured itch in a' is the wordplay.
'cured' indicates anagramming the letters.
'itch'+'in'+'a'='itchina'
'itchina' with letters rearranged gives 'CHIANTI'.
(Other definitions for chianti that I've seen before include "Chain it to popular Italian wine" , "I can hit for popular Italian wine" , "Dry red Italian wine" , "Italian wine variety" , "Wine produced in Tuscany" .)
