Used to drink it in Italy and recently bought some in a duty free shop on board. Had to have it packaged and the airline took it as baggage and sent it with my luggage since you can’t carry liquids on the plane.
Make sure the airline offers a solution if you buy liquids on board and have connecting flights!!!!! People get screwed that way.
Back to the topic, I don’t know the answer but would like to know. :hattip:
