Lemon Perfect, a growing brand in the enhanced water category, announced the launch of its newest flavor: Watermelon.

The new Watermelon flavor contains zero sugar, featuring the sweet taste of sun-ripened watermelons and the benefits of antioxidant vitamin C from real organic lemons squeezed into every bottle, the company says. It will be available in all Costco warehouses through May 21 in 15-bottle variety packs, alongside three of the brand's top flavors — Original Lemon, Peach Raspberry and Kiwi Star Fruit, it notes.

"Our watermelon flavor was a two-year journey from idea to landing in Costco," said Lemon Perfect Founder and CEO Yanni Hufnagel in a statement. "I'm proud of the work that our team put into commercializing our newest flavor and thrilled that Costco members nationwide can try it first as part of a mouthwatering four-flavor variety pack."

In addition to Costco, Lemon Perfect currently is available in various natural and conventional retailers across all 50 states, including Publix, Kroger, Whole Foods, Albertsons, CVS, Target, and more.
