Popwell

The best spec sheet on the page: 1 gram of sugar or less and 6 grams of fiber, a fifth of your daily value, which ties Simply Pop for the most fiber here behind Olipop’s 9 grams. Made by Talking Rain, the company behind Sparkling Ice, Popwell draws that fiber primarily from soluble corn fiber and sweetens with stevia rather than cane sugar. It is also the only brand here offering caffeine: Orange Cream, Classic Cola and Cream Soda each carry 40mg sourced from green tea extract, within an eight-flavor lineup that also runs Cherry Citrus, Blackberry Lime, Tropical Mango, Root Beer and Ginger Pop. The catch is that the critics have not caught up with the numbers — The Daily Meal placed it eighth of eight brands tested. Buy it if minimum sugar and maximum fiber are the priority, and start with the cream flavors.
