AHA, a brand of Atlanta-based The Coca-Cola Co., is expanding its line of sparkling waters with two new releases: Raspberry + Acai and Mango + Black Tea.

Driven by extensive research and consumer testing, the new varieties continue the brand’s formulation recipe of being free of calories, sodium and sweeteners.

“AHA consumers are variety seekers constantly looking for new and exciting flavors,” said Natalia Suarez, brand manager for AHA, in a statement on the company’s website. “We’ve always taken a consumer-centric approach with this brand, so we started out by exploring gaps and opportunities in our existing lineup to see how we could expand our reach. We think these new flavors taste delicious and are confident our fans will agree.”

The brand team started with more than 300 flavors and tested 42 pairings before optimizing the recipes for two top performers, the company says. The tropical taste of mango is complemented by a burst of black tea flavor (and 30 mg of caffeine), and the taste of raspberry is brightened by notes of acai, according to the company.

The new sparkling water releases are available in eight-packs of 12-ounce cans and in 16-ounce individual cans at select grocers and retailers nationwide.

Additionally, the company noted that new graphics will accompany the caffeinated varieties within AHA: Citrus + Green Tea and Mango + Black Tea.

“We’re treating this year as a relaunch,” Suarez said. “New flavors, new caffeine graphics and our first-ever integrated marketing campaign will build on our initial momentum as we pursue leadership in this fast-growing category.” 

Due to ongoing aluminum can shortages, AHA will discontinue two flavors: Black Cherry + Coffee and Apple + Ginger.
