When you’re celebrating the world’s biggest cruise ship, nothing small will do.The time-honored tradition of having a Godmother break a bottle of Champagne against the bow to bless the ship went bigger than magnum for the naming ceremony of Harmony of the Seas.

To celebrate the ship that has 16 decks and carries 5,200 guests, Royal Caribbean International commissioned Veuve Cliquot to make the biggest bottle of Champagne ever.
