PepsiCo, which embraced the 100-calorie concept with Frito-Lay snacks in 2006, has moved it over to the beverage side. A 100-calorie version of Pepsi was recently rolled out in 8-ounce cans, 85mm high. The cans bear the word “Joy” in big letters, with the round Pepsi logo used as the “O.” A six-pack of these aluminum cans, from Ball Corp., retails for $2.99.
