Pepsi versus Coca-Cola may be one of the most controversial drink debates of all time. A strong divide between diehard Coke drinkers and Pepsi enthusiasts has always existed. Yet, the two drinks are practically identical in every way from their caramel syrup color to their ingredients. Both sodas contain sodium, sugar, carbonated water, high fructose corn syrup, phosphoric acid, caffeine, and natural flavors.

In fact, a 12 ounce can of Pepsi contains one thing Coke does not—citric acid. In addition, Pepsi also has two more grams of sugar than Coke. These two subtle differences give Pepsi its sweet, citrus-like flavor that people either love or loathe. Plus, the additional 15 mg of sodium in a can of Coke may explain why it tastes more like a club soda with a toned-down sweetness.
