EMERYVILLE, CALIF. — Functional beverage brand REBBL is taking on the soda and ready-to-drink coffee categories with two new product lines: REBBL POP and REBBL Stacked Coffee.

REBBL POP is a sparkling functional soda designed to support immunity and digestive health, according to the company. Containing 50 calories and 5 grams of sugar per can, the beverages are formulated with prebiotics and come in four flavors: root beer, mandarin orange, blackberry and ginger lime. The drinks are USDA certified organic, non-GMO, vegan and gluten-free.

“We’re excited to bring a better-for-you alternative to the soda category,” said Bonnie Neulight, chief marketing and innovation officer at REBBL. “REBBL POP is the answer to the soda drinkers’ dilemma. With REBBL POP there is no more feeling of guilt nor yearning for taste.”

REBBL Stacked Coffee is a line of ready-to-drink cold-brew coffees designed to provide balanced energy and focus and immunity support, the company said. The beverages combine caffeine with green tea’s nootropic L-Theanine and are made with oat milk, reishi mushrooms, Lion’s Mane mushrooms and MCTs. The coffee comes in four flavors: café mocha, vanilla late, hazelnut latte and straight black. All varieties are USDA certified organic, fair trade, non-GMO, dairy-free, soy-free, gluten-free and vegan.

“We literally ‘stacked’ our best-tasting, fair trade coffee with premium function,” Ms. Neulight said. “Consumers will be left wondering how we stacked so many benefits into one phenomenal sensory experience.”

REBBL POP and REBBL Stacked Coffee is available nationwide at Whole Foods Market stores as well as on the company’s website and Amazon. REBBL POP 12-oz cans retail for $2.49, while REBBL Stacked Coffee retails for $3.99 per 12-oz bottle.
