No, wine has has to be in bottles, each not exceeding 750 ml each, with a limit of 2 for each adult 21 or older. I have seen people in different
DCL ports multiple times trying to argue the a single magnum (1500 ml) was the same as two 750 ml bottles and that a 3-liter box of wine was the same as four 750 ml bottles of wine for the 2 adults in the party, but in all of these cases, their wine was confiscated and they were given a reciept to pick it up at debarkation. I have also seen the same thing happen with people trying to play the math game with bottles and cans larger than 12-ounces but less than 6, adding up to less than the 72 ounces that a 6-pack of 12-ounce beers. Those were also confiscated, as DCL does not play math games to get to a total volume allowed, especially since the policy blatantly states that for wine each bottle cannot exceed 750 ml, while the beer container cannot exceed 12-ounces.
