Coca-Cola’s Recipe Vault
Coca-Cola’s recipe is perhaps the most famous trade secret in history. It now resides in an extraordinary vault that doubles as a tourist attraction. Company legend has it that only a tiny band of people knows the recipe. In December 2011, a metal box believed to contain the recipe was placed into a newly constructed 6.6-foot-high steel vault, which is not to be opened. The area is kept under constant surveillance.
