One thing people wonder about when Coke went from the New Coke back to the original formula is what happened to the sugar? It was replaced with high fructose corn syrup or sucrose. What's the deal? That's NOT the original formula.
Well, the New Coke didn't use sugar either. Bottom line was that the price of cane sugar was much higher than corn syrup. In 1980, Coca-Cola had already been using a 50-50 formula of sugar and corn syrup. Six months before New Coke hit the shelves, sugar was already gone from the formula in America. So, this change was made for economic reasons and, whether using sugar or corn syrup, Coca-Cola and Coca-Cola Classic are still Coke.
