Revealed Coca-Cola recipe could inspire home brews

A public radio show in the US claims to have uncovered the top secret recipe to Coca-Cola, challenging listeners to brew their own pop at home.

A weekly, public radio show This American Life, based out of Chicago, says they've discovered the original recipe for Coca-Cola buried quietly in the back pages of the Atlanta Journal-Constitution circa 1979 - a publication dedicated to the birthplace of this caramel-colored soda pop.

The radio show's website provides ingredients and exact measurements.

According to the recipe found in the Atlanta periodical, the following are key ingredients to the soft drink's top secret mix, also known as 7X:

List of ingredients:

Fluid extract of Coca 3 drams USP
