Coca-Cola secret recipe revealed

The original recipe for Coca-Cola — "one of the most jealously guarded trade secrets in the world" — has been uncovered by a Chicago Public Radio program.

The ingredients that make up one of the most popular soft drinks in the world had supposedly been a mystery since John Pemberton created the drink in 1886.

But according to the radio program This American Life, a photo of the coveted recipe was published in the Atlanta Constitution-Journal in 1979.

The recipe consists of two parts: caffeine, sugar, caramel and vanilla, but also "fluid extract of coca."

The second part — an exotic concoction called "Merchandise 7X," which includes cinnamon, nutmeg oil, neroli, orange oil and coriander — gives the pop its distinctive flavour, the radio show said.
