Is it true that there is a difference in taste between a Coke and a Pepsi?
assistant
Yes, it is. A Coca-Cola tastes sweeter than a Pepsi. This is due to the different types of sugar used in each beverage. The main ingredient in Coca-Cola is high fructose corn syrup, which is sweeter than regular table sugar. Pepsi uses aspartame as its sweetener instead of high fructose corn syrup. Aspartame is less sweet than table sugar, so Pepsi has a more subtle sweetness than Coca-Cola.
