As a wine it comes up to a blend of china (7)
I believe the answer is:
chianti
'as a wine' is the definition.
I can't tell whether this defines the answer.
'it comes up to a blend of china' is the wordplay.
'comes up' shows that the letters should be reversed in order.
'to a' means one lot of letters go next to another (I've seen this in other clues).
'blend of' is an anagram indicator (I've seen this in other clues).
'it' written backwards gives 'ti'.
'china' anagrammed gives 'chian'.
'ti' after 'chian' is 'CHIANTI'.
Can you help me to learn more?
(Other definitions for chianti that I've seen before include "Italian offering" , "Tuscan red wine" , "I can hit (anag) - alcoholic drink" , "Italian wine - mountain range" , "Dry red Italian wine" .)
