Wine served in Boudicca’s time (4)
I believe the answer is:
asti
'wine' is the definition.
(I've seen this before)
'in boudicca's time' is the wordplay.
'in' indicates a hidden word.
'ASTI' can be found hidden inside 'boudiccas time'.
'served' acts as a link.
(Other definitions for asti that I've seen before include "Italian town producing sparkling wine" , "Italian drunk" , "town in Italy" , "Capital of a north-west Italian province, known for its sparking wine" , "Italian white wine" .)
