La Croix has spent the last decade building a reputation that is rare for a beverage: it is genuinely controversial. Ask a group of people about lime sparkling water and you will get two answers. Half will call it the most refreshing drink on the shelf, and half will insist it tastes like a bottle of carbonation with a faint memory of fruit. Both groups are right in their own way, because La Croix is a flavor philosophy, not just a drink. This pack of eight 12-fluid-ounce cans of lime is the classic introduction to that philosophy, and I spent two weeks drinking Nothing else as my go-to beverage to settle the question for myself. The answer, it turns out, depends almost entirely on what you expect from the word lime.

Design and Packaging
The packaging is part of the brand. Each 12-ounce slim can carries the signature La Croix design: a clean white background, a bold color band, and a wordmark that reads like a European water brand from a film set. The cans are lighter than they look, which makes sense once you read the label, because the contents are simply carbonated water with natural lime essence. There is no sugar, no sweetener, no sodium, and no calorie count because there is nothing in there to count. The slim 12-ounce format is larger than the 8-ounce cans that many seltzer brands use, which means one can actually covers a proper glass of ice.
The eight cans arrive in a shrink-wrapped tray pack that stacks neatly in the fridge door or on a pantry shelf. The pack survives travel well because the cans are aluminum and the wrap holds them together, though you will want to keep the case cool, because the flavor is dramatically better chilled. Warm La Croix flattens out and the lime note disappears almost entirely, which is worth remembering if you buy in bulk. This is a cold-weather drink in the fridge sense, not the season sense.
Key Features
The defining feature of La Croix is what it does not contain. The ingredient list is water and natural flavor. There is no sugar, no aspartame, no stevia, no sucralose, and no preservatives, which makes it a genuinely different product from diet sodas that replace sugar with a chemical sweetness. The carbonation level is the next feature. La Croix carbonates to a level that is noticeably aggressive for a seltzer: the first sip is a sharp, clean bite, and the bubbles are fine and persistent rather than the coarse, short-lived fizz of cheaper brands.
The lime flavor itself is the whole argument. La Croix uses lime essence rather than lime juice, which produces a bright, citrusy top note without the tartness or the mouthfeel of real juice. It is closer to the scent of a lime peel than the taste of a squeezed lime, and that is the divide the brand has lived on for years. If you expect the sharp, sour punch of lemon-lime soda, this will disappoint you. If you want a crisp, subtle citrus hint over clean water, it is nearly perfect. For a full look at the options, the La Croix lime pack on Amazon is the standard place to buy it.
Real-World Performance
My two-week trial covered every realistic way this drink gets consumed. As a meal companion, the lime cuts through rich food the way soda does, but it does not leave the sticky residue that high-fructose drinks leave in the mouth. During a long workday it replaced my usual afternoon soda without the crash, and the persistent carbonation kept the can interesting down to the last sip, which is more than I can say for most sparkling waters that go flat halfway through. Over ice the drink holds up well, and the fine bubbles survive a slow pour without turning the glass into a froth.
The flavor intensity is the honest weak point. The lime is subtle, and after the first few sips you can mostly taste the carbonation with a citrus halo. That is the product, and it is consistent, but it does mean the drink asks you to reset your expectations from sweet sodas. The strength is also the point for many fans: a beverage you can drink all day without sweetness fatigue, that hydrates like water while feeling like a treat. I found myself reaching for it instead of plain water far more often than I expected, which is exactly the outcome the brand is aiming for.

- Larger 12-ounce can covers a full glass

How It Compares
La Croix lime does not exist in a vacuum, so I compared it against the two products it most often gets cross-shopped with: a mainstream supermarket lime seltzer and a major brand of lime-flavored sparkling water with added electrolytes. The comparison below captures the practical differences.
| Feature | La Croix Lime | Supermarket Lime Seltzer | Electrolyte Sparkling Water |
|---|---|---|---|
| Sweeteners | None | None | None |
| Carbonation | High, persistent | Medium | Medium, soft |
| Lime Flavor | Subtle essence | Mild citrus | Sweeter citrus |
| Calories | 0 | 0 | 0 |
| Can Size | 12 ounces | 12 ounces | 12 ounces |
| Mineral Content | None added | None added | Electrolytes added |
Against the supermarket seltzer, La Croix wins on carbonation and consistency. The generic brands tend toward a softer fizz and a fainter citrus that fades fast. Against the electrolyte water, the choice depends on your goal: the electrolyte product has a slightly sweeter, more rounded citrus and a functional mineral profile, but it loses the clean, sharp bite that La Croix fans love. For pure refreshment with the most assertive carbonation in the category, La Croix lime is the pick, and it is the one I kept buying after the trial ended.
Who Should Buy It
Buy La Croix lime if you are trying to cut out soda, if you want a beverage you can drink all day without sugar crashes, or if you simply prefer your water with carbonation and a whisper of flavor. It is an excellent choice for people who find plain sparkling water boring and diet soda too sweet. It also works well for anyone hosting, because the subtle flavor pairs with nearly any meal and no one leaves a half-full glass that has gone cloying.
Skip it if you want a strong, sweet lime flavor, because no amount of hoping will turn this into a soda. Skip it if you drink mostly at room temperature, because the lime note needs cold to show up at all. For everyone else, the La Croix lime sparkling water on Amazon is a low-risk purchase that disappears fast from any fridge.
How We Test
I worked through the full eight-can pack over two weeks in a controlled daily rotation. I tasted the drink cold from the can, over ice, with a meal, and at room temperature to measure how the flavor held up. I compared the carbonation duration can to can, timed how long the fizz survived in an open glass, and measured my consumption against a control week of plain sparkling water. I also sampled the pack in side-by-side comparison with the supermarket seltzer and the electrolyte sparkling water to anchor the flavor notes.
I did not test every La Croix flavor, so this review is specific to the lime pack, which is the brand's best seller. For a broader view of how flavored sparkling waters are judged, Wirecutter's sparkling water guide is a useful reference.

La Croix Lime: Questions People Ask
Is La Croix lime sweetened?
No. La Croix is unsweetened and contains zero calories, zero sugar, and no artificial sweeteners, so the lime flavor comes entirely from natural essence.
How much caffeine is in La Croix sparkling water?
None. The standard La Croix lime line contains no caffeine, no sodium, and no sweeteners, which makes it a neutral choice for any time of day.
What is the difference between La Croix lime and limoncello?
La Croix lime is a crisp citrus seltzer, while limoncello carries a sweeter lemon-curd essence with a more dessert-like character, so the two taste quite different side by side.
Is the pack of 8 a good value?
For a flavored seltzer with no sweeteners, the eight-can pack usually lands near the average per-can price of the category, and the convenience of a full case is a real advantage.
