Rosso o bianco
I believe the answer is:
vino
'rosso o bianco' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for vino that I've seen before include "Cheap wine" , "Italian or informal wine" , "Italian wine - any brand" , "In - veritas means alcohol promotes truth-telling" , "Wine, colloquially" .)
