An American radio show claims to have found a recipe detailing the secret ingredients and method for making Coke.
When curiosity got the better of Atlanta pharmacist John Pemberton in 1886, little did he know that his creation would become such a massive hit around the globe.
"A century later, The Coca-Cola Company has produced more than 10 billion gallons of syrup. Unfortunately for Pemberton, he died in 1888 without realising the success of the beverage he had created," the company says.
"Imitation may be the sincerest form of flattery, but The Coca-Cola Company was none too pleased about the proliferation of copycat beverages taking advantage of its success.
"Coca-Cola has grown to the world's most ubiquitous brand, with more than 1.4 billion beverage servings sold each day."

So with such a successful product, it is easy to understand why the company would want to protect its secret flavouring formula.
Now This American Life says it has found the original recipe.
"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," the radio show says.
"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."
This American Life says staff were surprised to find 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," the show says.
Other ingredients in the recipe include sugar, water, lime juice, Cinnamon Oil, Nutmeg Oil and lemon oil.
Asa G. Candler transformed Coca-Cola from an invention into a company in 1893.
His son Charles Howard Candler wrote a book in which he detailed how protective his father was of the secret formula - known as Merchandise 7X - including checking the mail himself and removing invoices detailing ingredients, This American Life presenter Ira Glass said.
"There was no written formula and the labels had been removed from all the containers of the ingredients," Candler said of the Coke lab.
"They were identified only by sight, smell and remembering where each was put on the shelf."
It is understood that only two people at any given time know how to mix the 7X ingredients. They don't even travel on the same plane together.
