American state consumed by unfermented grape juice from Asian capital (6)
I believe the answer is:
muscat
'asian capital' is the definition.
'Muscat' can be an answer for 'capital' (Muscat is an example). I'm not sure about the 'asian' bit.
'american state consumed by unfermented grape juice' is the wordplay.
'american' becomes 'us'.
'state' becomes 'ca'.
'consumed by' means one lot of letters goes inside another.
'unfermented grape juice' becomes 'mt' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'us'+'ca'='usca'
'usca' put within 'mt' is 'MUSCAT'.
'from' is the link.
Can you help me to learn more?
(Other definitions for muscat that I've seen before include "Sweet aromatic grape" , "wine producer" , "Type of grape and the capital of Oman" , "Type of 18" , "Sweet fortified wine" .)
