"Bonus fact: Coca-Cola’s recipe contains a heavily guarded mystery flavoring, known as the “7X flavor.” In early 2011, This American Life broadcast an episode[1] discussing a potential early recipe for the drink, but almost certainly not the one in use today. Coke denied[2] that the program had discovered the true formula. In that episode, Mark Pendergrast, author of For God, Country, and Coca-Cola, an unauthorized history of the company (and beverage), told This American Life[3] that “only two people know how to mix the 7x flavoring ingredient” and that “[t]hose two people never travel on the same plane in case it crashes; it’s this carefully passed-on secret ritual and the formula is kept in a bank vault.”"
