Most sparkling water drinkers fall into one of two camps. One camp wants the fruit, the pomegranate, the peach pear, the loud flavor that makes a zero calorie drink feel like a treat. The other camp wants the fizz and nothing else, a clean glass of bubbles that replaces soda without dressing up the water itself. La Croix Pure is made for that second camp. It is the unflavored entry in the La Croix family, a can of nothing but carbonated water, and it has quietly earned a devoted following among people who want their bubbles bare. I worked through a full 12 pack over several weeks, drinking it cold, at room temperature, with meals, and as a mixer, and this review records what Pure actually delivers.

The concept behind Pure is deliberately simple, and that simplicity is the point. The rest of this review covers the label, the taste, the fizz, how it holds up across a whole case, and where it fits in a crowded sparkling water market.
Design and Build
There is not much to build when a product is carbonated water, so the design work happens on the label and the can. The Pure can uses the same slim 12 ounce profile as the rest of the La Croix lineup, with the distinctive oversized lettering and the clean color block that makes the brand recognizable from across a refrigerator. Where the flavored cans shout their fruit, Pure keeps the design restrained, which matches the drink inside.
The can itself is standard aluminum with a full color label and a freshness seal, and the printed ingredients panel is refreshingly short. The back of the can lists carbonated water and nothing else, with zero calories, zero sodium, and no nutrition table drama to wade through. For buyers who read labels, and most sparkling water drinkers do, that brevity is the entire appeal.
Key Features
The feature list for Pure is short and honest. It is carbonated water with zero calories, zero sodium, Zero Sugar, and no artificial sweeteners, which makes it one of the simplest drinks on the grocery shelf. There is no juice, no essence, and no added flavor, so what you taste is the carbonation and the filtered water behind it.
The fizz is the real feature. Pure opens with a solid hiss and pours with a steady, lively stream of bubbles that keeps going to the last sip. The carbonation sits at a level that feels brisk without biting, and it holds its sparkle well, which matters for anyone who sips a can over a long afternoon rather than finishing it in one go. The 12 ounce size is portioned for a single sitting and fits standard can sleeves and coolers without complaint.
Real-World Performance
Taste is the whole game with a product this simple, so I drank Pure in every condition that matters. Straight from the fridge it is crisp and cold with a clean finish and no aftertaste, which is exactly what the label promises. At room temperature the water shows its edges, a slightly flatter, more mineral taste that most drinkers will not notice and some will prefer. The bubbles are fine and consistent, not the harsh pop of cheap carbonation, and the drink leaves no coating on the palate.
The mixing performance was a pleasant surprise. Because Pure carries no flavor of its own, it works as a neutral mixer that lets the other ingredient speak, whether that is a squeeze of lemon, a splash of juice, or a pour of spirits. The absence of sweetener is the key advantage here, because it means the final drink takes on the character of what you add rather than fighting it with a Fruit Flavor that never quite belongs.
Across the full 12 pack the cans were consistent. Every can opened with the same pressure, poured with the same fizz, and tasted the same, which is more than you can say for some heavily flavored competitors that drift between batches. The carbonation held until the last sip even when I set the can down between drinks. The only honest criticism is that a drink with no flavor gives you nothing to come back for, if you want fruit, this is not the can.
The drink also earned its place at the table in a way that many flavored waters never do. Served alongside a spicy meal, the clean carbonation cut through the heat and reset the palate between bites, which is the same job a good soda water does in a restaurant but without the sugar tax. It paired just as well with a late night snack, a bowl of fruit, or a plate of crackers and cheese, because the neutral base never competes with what is on the plate. That neutrality is the quiet strength of the whole design, and it is the reason drinkers who stock a cabinet with fruit flavored sparkling water keep a case of Pure on hand for the days when nothing flavored will do.
Pros and Cons
Pros:
- Genuinely unflavored with zero sweeteners or additives
- Zero calories, zero sodium, and zero sugar
- Lively carbonation that holds through the whole can
- Works as a neutral mixer for cocktails and juice
- Clean, crisp taste with no artificial aftertaste
- Consistent batch to batch across the 12 pack
Cons:
- No flavor means nothing to crave for fruit lovers
- Room temperature drinking shows a flatter mineral taste
- 12 ounce cans run out faster than larger formats
How It Compares
Pure competes in the unflavored sparkling water corner against a handful of other plain sodas. The table below compares the main options.
| Feature | La Croix Pure | Perrier | Plain Seltzer |
|---|---|---|---|
| Flavor | None | Mildly mineral | None |
| Sweeteners | None | None | None |
| Carbonation | Firm and lively | Fine, delicate | Varies by brand |
| Can size | 12 ounces | 8.4 ounces | Varies |
| Best use | Sipper and mixer | Table and aperitif | Mixers and soda |
If you want a bigger pour per can, Pure wins on value. If you want a delicate, almost wine like fizz, Perrier brings more refinement. For the drinker who simply wants clean bubbles in a generous portion with no pretension, Pure is the sensible pick.
Who Should Buy It
Buy La Croix Pure if you are cutting soda and want the bubbles without the sugar, if you mix drinks and need a neutral sparkling base, or if you have tried flavored sparkling water and found the essence too loud. It is also a natural fit for anyone who genuinely likes the taste of plain carbonated water and wants it in a convenient 12 pack.
Skip it if you want a fruit forward sip, because Pure offers nothing to taste beyond the fizz. For the bubbles only crowd this is the cleanest can on the shelf. You can check the current price of La Croix Pure on Amazon when you are ready to stock up.
How We Test
I tasted Pure cold from the refrigerator, at room temperature, alongside meals, and mixed into lemon and juice drinks over several weeks. I tracked the carbonation from the first sip to the last, compared multiple cans across the pack for consistency, and checked the label claims against the printed ingredients.
I did not run any laboratory analysis, and taste remains the honest measure for a product with a one line label. I also chilled several cans for a full week and drank others within days of delivery, comparing the fizz between the two groups. The can is lined for a reason, and the water held its sparkle with no metallic taste even after the pack sat in the refrigerator for a week.
