I think I drank it and thought it tasted basically like Pepsi Cola. Maybe not as good but okay. I’m not a big soda drinker, a few a week.
The only difference between Crystal Pepsi and Pepsi is the flavorless, artificial "caramel" coloring.
They should taste exactly the same - my assumption when they first came out with it was: "They are charging the same price while pocketing the cost of the coloring, right?"
