Sodastream and PepsiCo are using the Florida market to test make-at-home soda. Sodastream stock was up 15% on the news. The deal gives Pepsi a new sales channel in an anti-sugar, anti high-calorie environment. The 10-week test in Orlando and Tampa includes naturally sweetened Pepsi Homemade and Sierra Mist Homemade with 50-60 calories per serving. Coca-Cola is planning a similar move with Keurig.
