ST. PETERSBURG, FLA. — Mother Kombucha is brewing up a new beverage line: Agua Bucha kombucha-infused sparkling water.

Containing 4 calories and 1 gram of sugar per 12-oz can, the certified organic drink comes in Key lime, Meyer lemon and grapefruit flavors. Agua Bucha is shelf stable without pasteurization due to a proprietary process, the company said.

“Agua Bucha evolved from customer feedback over the last six years,” said Tonya Donati, founder and managing partner of Mother Kombucha. “Mother Kombucha has always been a category leader in low sugar and calories, but we saw an opportunity for further innovation. We spent two years developing our process and held it to the same high standards as our core kombucha line. Before going to market it had to be delicious, fairly and cleanly sourced and priced right. Agua Bucha continues our mission of making kombucha delicious and accessible to more people, and we are thrilled to bring kombucha benefits to the water aisle.”

Agua Bucha joins Mother Kombucha’s namesake line of kombucha in the company’s beverage portfolio. The kombucha comes in eight varieties: turmeric ginger lemonade, blue rose, goji grape, lavender mojito, pineapple coconut, jasmine flower, blood orange ginger and hopped passionfruit. F
