Crystal Pepsi was originally introduced in 1992 as a caffeine-free clear cola soda. Clear beverages and other products were trending in the early 90’s and Pepsi looked to capitalize on this market. However, Crystal Pepsi never took off with consumers. It was discontinued within about year.

Crystal Pepsi was reintroduced in the summer of 2016. The new version of the soft drink does have caffeine as indicated above. It is meant to taste like regular Pepsi but many people note slight differences between Crystal and regular Pepsi. Several people have noted a crisp or lighter taste to Crystal Pepsi.
