The world's largest soft drink maker, Coca-Cola, said that the recipe for its flagship beverage is still a secret after 125 years, disputing a claim by a public radio show that it uncovered the formula. “This American Life,” a weekly public radio program based in Chicago, said it found the recipe in an article in the Atlanta Journal Constitution, Coke's hometown newspaper. The article was published in February 1979, according to the story.
The original article was published with a photo showing pages from a notebook with a handwritten list of ingredients. The radio show claims the notebook belonged to a friend of John Pemberton, the pharmacist who originally created Coca-Cola in 1886. Coke has denied that the formula is the same as that used for its popular drink, a formula that is kept n a bank vault in Atlanta.
The show said that the formula from the 1979 article matches another one previously found in a notebook that belonged to Pemberton, a recipe that can be found in Coke's archives. Archive director Philip Mooney told the show that many similar recipes have surfaced over the years that somebody has claimed is the formula for the world's most popular cola, but Mooney believes all were just attempts at discovering the recipe and that the original formula is still a well-kept secret.
