Coca-Cola has now confirmed details of its mainstream sparkling water launch, which we first wrote about in August (BD 8/29/19). Called Aha, the brand’s March debut will challenge National Beverage’s LaCroix and PepsiCo’s Bubly. Until now, Coke has resisted entering the mainstream sparkling water category with a sweeping challenger, opting instead for line extensions of Dasani and Smartwater, plus Topo Chico. Aha marks a reversal of that strategy as Coca-Cola aims to capitalize on the struggles of market leader LaCroix while slowing down the relatively unchecked growth of category disruptor Bubly. Aha’s success will depend largely on Coke’s ability to grab consumers’ attention in a crowded category that offers little differentiation between mainstream formulas.
