Coca-Cola and Pepsi compared to Coca-Cola relatively low in sugar, high in carbonic acid gas, Pepsi high in sugar, no gas when you drink like brown sugar water, the taste is slightly different, there are tests show that more people prefer the flavor of Pepsi. I'm afraid the biggest difference is in the brand appeal of the values, Coca-Cola since the table for "real cola", and Pepsi since the table for "young people's cola".

Coca-Cola's sugar content is relatively low, suitable for middle-aged and elderly people, while Pepsi's sugar content is high, suitable for young people to watch themselves drink. Pepsi's phosphoric acid content is a little more than Coca-Cola's, the taste feels a little "hard" a little, Pepsi is a little sweeter. In fact, Pepsi contains more sugar, calories and caffeine, while Coca-Cola contains more sodium.
