Who found out that Pepsi is sweeter than Coke?

The perception that Pepsi is sweeter than Coke was notably highlighted in the "Pepsi Challenge," a marketing campaign initiated in the 1970s. In blind taste tests, many participants preferred the sweeter flavor profile of Pepsi over Coke. This phenomenon can be attributed to the differing formulations of the two sodas, with Pepsi generally containing more sugar and a slightly different blend of flavors, leading to the perception of increased sweetness.
