When it comes to sparkling water, Perrier and LaCroix represent two completely different philosophies. One is a historic French import packaged in green glass, associated with dining tables and cafes. The other is a colorful, midwestern-born seltzer in aluminum cans that single-handedly catalyzed modern American seltzer culture.
While they compete for the same shelf space in the grocery store, they are fundamentally different products. Understanding what goes into each bottle makes choosing between them simple.
Short answer: Perrier is a naturally sourced French mineral water with real mineral content and assertive, fine carbonation. LaCroix is a flavored seltzer made from purified municipal water with natural flavor essences. Perrier is a premium, higher-priced drink best for dining and cocktail mixing. LaCroix is an affordable, everyday zero-calorie seltzer with massive flavor variety.

The Fundamental Difference
The most important distinction between the two brands is the source of the water:
- Perrier is a sparkling mineral water. Sourced from a volcanic aquifer in Vergèze, France since 1863, the water filters through underground limestone layers, naturally absorbing minerals. Per liter, Perrier contains approximately 147 mg of calcium, 3.4 mg of magnesium, and 9 mg of sodium. Under FDA regulations, these minerals must emerge naturally from the spring; they cannot be added later.
- LaCroix is a flavored seltzer. Sourced from municipal water systems in the United States, the water goes through reverse osmosis filtration to strip away all minerals and impurities. Carbon dioxide and natural fruit essences (aromatic compounds derived from plants) are then added. LaCroix contains zero minerals and zero sodium.
LaCroix was actually launched in La Crosse, Wisconsin in 1981 by G. Heileman Brewing Company specifically to compete with Perrier. The brand’s early positioning was explicitly “anti-snob,” pitching itself as a down-to-earth American alternative to the chic, expensive French import.
Taste & Carbonation Comparison
Because of their different mineral profiles and carbonation methods, Perrier and LaCroix feel very different on the tongue:
- Perrier features assertive, fine, and persistent carbonation. The bubbles are small and highly active, giving it a tannic, crisp finish. The presence of natural minerals gives the water a slightly thick mouthfeel. In blind taste tests published by Food52 and The Takeout, Perrier is consistently praised for having a “pitch perfect” balance that cleanses the palate during dining.
- LaCroix features medium-sized, standard carbonation and subtle flavor hints. The flavor profile of LaCroix is understated—Pamplemousse (grapefruit) is famously described as tasting like “someone whispered the name of a fruit in another room.” This lightness is preferred by drinkers who want daily hydration without a strong mineral or juice taste.
Price Comparison
- Perrier: Approximately $1.00 to $1.50 per 16.9oz glass bottle at retail (roughly $0.06 to $0.09 per ounce).
- LaCroix: Approximately $0.33 to $0.40 per 12oz can in a 12-pack (roughly $0.03 per ounce).
Per ounce, Perrier costs roughly three times as much as LaCroix. If you drink two or three cans of sparkling water per day, stocking your fridge with LaCroix represents a significant cost saving over Perrier.
Which One Should You Buy?
Choose Perrier if:
- You want a natural mineral water with a distinct geological profile.
- You enjoy the premium drinking experience of pouring from a green glass bottle.
- You are pairing your water with a rich meal at the dinner table.

- You prefer a clean, light seltzer without any mineral taste.
- You want convenient, lightweight aluminum cans for stocking in bulk.
