Quite random... I know! I bought a 20oz bottle today and was really surprised to see that the sugar content is higher than I remember it. I believe in a 20oz bottle, it contained about 46g of sugar. Now, that same bottle contains about 77g of sugar. Something else that was interesting is that Pepsi prints how much caffeine content is in the bottle. For the 20oz bottle, that is 91mg. I've been drinking this stuff for years. It's terrible for you but so are a lot of other things.
