Wine from Hastings (4)
I believe the answer is:
asti
'wine' is the definition.
(Italian wine)
'from hastings' is the wordplay.
'from' indicates the answer is hidden within the clue.
'ASTI' can be found hidden inside 'hastings'.
(Other definitions for asti that I've seen before include "Italian white wine" , "Sparkling drink" , "18" , "- spumante, It. wine" , "Piedmont wine city, SE of Turin" .)
