White wine -- some bucellas tippled (4)
I believe the answer is:
asti
'white wine' is the definition.
(I've seen this before)
'some bucellas tippled' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'ASTI' is hidden in the letters of 'bucellas tippled'.
(Other definitions for asti that I've seen before include "It's a (anag) - wine" , "- spumante, It. wine" , "Italian town, famous for its wine" , "Italian drunk" , "Italian town producing sparkling wine" .)
