Wine is not subject to the five-liter per Customer limitation. Alcohol content may not exceed 70% by volume (140 proof). Alcohol (wine and liquor) in checked baggage should be securely packaged in a leak-proof bag with adequate professional packaging designed to fit the proportions of the bottle to prevent breakage.

Traveling with a box of wine (bag-in-box) is actually much safer and more efficient than traveling with glass bottles, but it requires specific care in checked luggage. Because the wine is in a flexible, air-tight bladder inside the cardboard box, it is not prone to "shattering" like glass; however, the box can be crushed, which might burst the plastic bag. The best method is to wrap the entire box in a large, heavy-duty Ziploc bag or a plastic bin liner to prevent any leaks from soaking your clothes. In 2026, most travelers prefer to remove the bladder from the cardboard box entirely, wrap it in a layer of clothing, and place it in the center of their suitcase for natural "padding," which also saves significant space. It is important to remember that you cannot bring a box of wine in your carry-on due to liquid restrictions, and you should always check the customs limits of your destination country to ensure you don't exceed the personal allowance for alcohol imports.
