LaCroix Key Lime is the newest flavor for the sparkling water company, and the flavor is bound to be a crowd-pleaser. According to the company, the canned sparkling water flavor is meant to be reminiscent of key lime pie.
To be sure, LaCroix Key Lime stays in line with the company's general ethos. LaCroix is all about offering a flavored beverage that's subtly sweet without being overpowering or leaving drinkers with the unpleasant mouthfeel that accompanies sugary food and drinks. Though LaCroix Key Lime is indeed inspired by the pie, it has a "sweet-and-tart flavor" that's still gentle enough to leave drinkers' thirsts quenched.
The flavor is sweeter than the brand's Lime flavor but also slightly more tart.
