Since its invention by John Pemberton in 1886, Coca-Cola has become the most well known soft drink in the world. Yet who actually knows the Coca-Cola recipe?
On its website, Coca-Cola claims the company's "secret formula for making Coca-Cola has remained a trade secret for 130 years." Shrouding the drink's ingredients in secrecy "creates a natural curiosity about the product itself," according to social psychologist and marketing expert Ben Voyer.
As the years have passed and speculation concerning the Coke recipe has grown, people have come out of the woodwork claiming to know the recipe and other company secrets. Yet Coca-Cola insists its methods remain unknown by the public. So how does Coca-Cola protect its formula?
