Root Beer Prebiotic Soda
poppi · Prebiotic functional soda
Austin, Texas, USA
poppi reframes root beer as a gut-health play: cassava root fiber and agave inulin do the prebiotic lifting while organic cane sugar and stevia keep it to a featherweight 5 grams of sugar. The result reads as a recognizable root-beer sketch — soft sassafras and vanilla over a thin, briskly carbonated body — but the low-calorie build shows, with a slack mid-palate and a stevia-tinged sweetness that fades fast on the finish. poppi's signature apple cider vinegar lends a faint tartness uncharacteristic of the style, and the absence of real molasses or bark depth keeps it firmly in the "better-for-you" lane rather than the connoisseur one. A clean, easy, modern take that trades richness for function.

The maker
Poppi is a prebiotic soda brand founded by Allison and Stephen Ellsworth, who began developing an apple-cider-vinegar-based soda in their home kitchen and first sold it at Texas farmers markets before a 2018 Shark Tank deal. Now headquartered in Austin, Texas, the brand reformulates classic soda flavors like root beer with cassava root fiber and agave inulin for added prebiotic fiber and low sugar. PepsiCo acquired Poppi in 2025.
