The Secret Ingredient That Makes LaCroix Water So Irresistible

The distinctive Technicolor cans of LaCroix sparkling water are an increasingly popular sight in stores and on kitchen tables around the country. (If you're old enough to remember the Snapple phenomenon of the 1990s, this is like that—just bubbly.) But as The Wall Street Journal recently pointed out, few of the beverage's loyal fans have any idea what it is they're drinking.

LaCroix comes in a variety of flavors, from tangerine to coconut. The can label, however, is cryptic, listing "natural flavors" as part of the ingredients. Their website discloses only that "natural essence oils" are involved, which sounds like LaCroix should be applied to your hair and then rinsed off.

As it turns out, that's not too far off. According to The Wall Street Journal, these "essences" are naturally produced chemicals that are manufactured by heating up fruit or vegetable remnants until they make a vapor, then condensing them into a clear concentrate. They're used in a variety of consumer products, from shampoos to ice pops.

LaCroix was unwilling to confirm the Journal's claim, protecting their manufacturing process in a manner similar to Coca-Cola's famously secretive treatment of their recipe. They do state that no sugars are added, but that may not be enough to protect your teeth: Carbonated water and citric acids can combine to create a lower pH, which has a detrimental effect on tooth enamel. Like most everything that tastes good, these flavored waters are best enjoyed in moderation.
