Today, the original formula, whatever version Coca-Cola considers official is housed in a custom-built vault inside the World of Coca-Cola in Atlanta. Tourists line up to stand in front of it. The vault door is thick, dramatic, and very deliberately designed to remind you that something priceless lives inside. Whether the real recipe is in there, or whether it was quietly sitting in a newspaper archive all along, is a question Coca-Cola will never answer.
