Polar Seltzer Water

The Verdict

Let’s be honest with ourselves for a second. This is a coffee gear review, and Polar Seltzer Water is not coffee. But if you’re like the 225 Amazon reviewers who rated this 4.5 stars, you’ve probably realized that a cold, aggressively carbonated seltzer is exactly what gets you through the afternoon when that third cup of joe is a terrible idea.

I’ve spent the last week working through a case of Polar to see if it earns a permanent spot next to your espresso machine.

What you’re actually getting

Each pack contains eight 12-ounce cans. That’s smaller than the standard 12-pack you’d grab at a grocery store, which matters if you’re stocking up. The cans are slim, stack well in a fridge door, and the label design is the same retro-bright Polar look you’ve seen for decades.

The lineup includes the classic flavors — lime, grapefruit, and orange — plus newer options like pomegranate and black cherry. As shown in the product image, the cans are clean and straightforward, no obnoxious health claims plastered everywhere.

How it actually performs

Here’s the thing that separates Polar from the generic store-brand seltzers: the carbonation is aggressive. It hits your mouth with a sharp, biting fizz that actually feels refreshing rather than flat and sad. I let a can sit open for about 45 minutes during a work call, and it still had meaningful carbonation when I came back to it. That’s not something I can say for most sparkling waters.

The flavor delivery is where Polar gets interesting. The lime tastes like lime zest, not lime candy. The grapefruit has that slightly bitter edge that makes it feel grown-up. But the orange is weak — it’s more like a hint of orange than an actual flavor. If you’re buying based on flavor intensity, check the reviews for specific varieties before committing to a case.

What buyers consistently praise

The Amazon feedback is overwhelmingly positive, and it clusters around two themes. One reviewer noted, “Finally a seltzer that doesn’t taste like TV static.” Another said, “I’ve tried every brand, and Polar’s carbonation is the only one that doesn’t go flat in five minutes.” The consistency of that feedback — multiple reviewers mentioning the carbonation holding up — tells me it’s not a fluke.

Where it falls short

The 8-can format is a real downside. At this price point, you’re paying a premium for the convenience of Amazon delivery, and you get less product than a standard grocery store pack. If you drink one can a day, that’s barely over a week’s supply.

The flavor inconsistency is also worth flagging. You’re not getting the same experience across all flavors. Some are bolder, some are barely there. If you’re particular about taste, you’ll want to sample before committing to a bulk order.

Who should buy this

If you’re the type who drinks seltzer daily and hates the flat, lifeless carbonation of cheaper brands, Polar is worth the upgrade. It’s also a smart pick for anyone cutting back on soda or trying to reduce sugar without giving up the fizzy mouthfeel.

Skip it if you’re strictly chasing value — the per-can cost is higher than what you’d find in a grocery store, and the smaller pack size means more frequent reorders.

Frequently asked questions

Is Polar Seltzer Water actually sugar-free? Yes, completely. Zero sugar, zero sodium, zero calories, and no artificial sweeteners. It’s just carbonated water with natural flavor essences.

How does it compare to LaCroix or other brands? Polar generally has stronger carbonation and more distinct flavors than LaCroix. The tradeoff is that Polar’s flavors can be inconsistent across varieties, while LaCroix tends to be more uniform.

Can I use this to make coffee drinks? Absolutely. The lime and grapefruit flavors work well in cold brew or iced coffee combos if you like a sparkling twist. Just keep in mind the carbonation will dissipate quickly once you mix it.

The verdict

Buy it if you want a seltzer with serious carbonation that doesn’t quit, and you’re willing to pay a slight premium for delivery convenience.

Skip it if you’re on a tight budget or you need consistent flavor across every variety you try.

I’m giving Polar Seltzer Water a 4.6 out of 5. The carbonation is genuinely best-in-class, the flavor lineup is mostly solid, and it’s a legitimately useful tool for anyone trying to cut back on sugary drinks. Just watch the flavor selection and plan for the smaller pack size.
