The formula for Coca-Cola is one of the most jealously guarded trade secrets in the world. Locked in a vault in Atlanta. Supposedly unreplicable. But we think we may have found the original recipe. And to see if the formula actually might be Coke, we made a batch. Or, anyway, we asked the folks at Jones Soda and Sovereign Flavors to whip up some up, to see if it tastes like Coke. The recipe is here.

Act One. Message In a Bottle.

The formula for Coca-Cola is one of the most jealously guarded trade secrets in the world. So we were surprised to come across a 1979 newspaper article with what looked like the original recipe for Coke. Talking to historian Mark Pendergrast, author of For God, Country and Coca-Cola, we were even more surprised when we found reasons to believe the recipe is real. (25 minutes)
