Polar Seltzer Flavors: The Complete Guide (2027)

Polar is the seltzer that’s been around longer than almost anyone realizes. It started in 1882 in Worcester, Massachusetts, when a bartender named Dennis Crowley put together a carbonation recipe to help sell more whiskey. Prohibition changed his plans, and the seltzer stuck around long after the whiskey business faded. More than 140 years later, Polar is still run by the Crowley family, now in its fourth generation with Ralph Crowley Jr. at the helm, and it’s the largest independent soft drink bottler in the United States.

That family ownership matters, since a lot of people assume a brand this big must belong to Coke or Pepsi by now. It doesn’t. Polar has stayed private and independent the whole way through, and the company genuinely does say Pepsi and Coke launching their own seltzer lines over the years only ended up helping Polar’s position rather than hurting it.

What's Actually in a Can of Polar Seltzer

Two ingredients: carbonated water and natural flavors. That’s it for the flavored line. The original, unflavored Polar Seltzer is just water and bubbles. No sodium, no sugar, no sweeteners, no fluoride, no caffeine, and no gluten in any of it.

The natural flavors themselves come from real sources, things like lemon peel, vanilla bean, and mint leaves, extracted and distilled into concentrated flavor essences. Polar has said it uses a locally sourced water supply that goes through reverse osmosis filtration before bottling.

One small but genuinely useful thing to know: if your doctor has told you to avoid grapefruit because of a medication interaction, that warning extends to Polar’s grapefruit flavored seltzer too, since it’s made with real grapefruit flavoring.

Polar's Different Product Lines

This is where people get mixed up, since “Polar” covers more than one kind of drink.

• Polar Seltzer: The core line, the one most people mean when they say “Polar Seltzer.” Carbonated water and natural flavors, nothing else, caffeine free.
• Polar Seltzer’ade: A separate line built around lemonade and limeade style flavors, made with the essence of real lemons or limes plus a matching fruit flavor. Still no juice, sugar, or sweeteners despite the “ade” in the name, and it’s sold year-round rather than seasonally.
• Polar Seltzer Jr: A kids-focused line sold in smaller 7.5-ounce cans, with playful flavor names like Unicorn Kisses and Mermaid Songs. Same clean ingredient list as the standard line, just a smaller can and a more colorful name.
• Polar Frost: Different from the rest of the family in one important way: it actually contains caffeine and vitamins.
• Polar Sparkling Dry: Closer to a lightly sweetened soda than a seltzer, made with about 10 percent real fruit juice along with natural fruit essences.
• Polar Club Soda & Tonic Water: Mixer style products. Club soda has added mineral salts (potassium citrate and sodium bicarbonate), and tonic water contains real quinine along with sweetener, both meant more for cocktails than solo sipping.

Does Polar Seltzer Have Alcohol In It?

No. This is a genuinely common question, and the confusion comes from the broader “hard seltzer” trend that took off with other brands. Polar does not currently make any hard seltzer products. Every Polar Seltzer, Seltzer’ade, and Seltzer Jr can on the shelf is entirely alcohol-free.

Best Polar Seltzer Flavors Ranked

If you want to know which Polar flavor is best, here are the best polar seltzer flavors ranked by taste, popularity, and overall drinkability. Which Polar flavor is most popular? Ruby Red Grapefruit has held the top spot for over two decades.

Polar’s standing lineup runs well over a dozen flavors, with these among the most consistently available and best known:

• Ruby Red Grapefruit: Polar’s signature, top-selling flavor, introduced in the 1990s and still the one most associated with the brand. It’s tart and true to the fruit without leaning artificial.
• Black Cherry: Deep and full-flavored, a longtime favorite for anyone who wants something bolder than a citrus option.
• Lime: Straightforward and citrusy, a reliable everyday pick and a common cocktail mixer.
• Cranberry Lime: Blends tart cranberry with a citrus edge, one of the flavors most frequently bundled into Polar’s core variety packs.
• Raspberry Lime: Pairs berry sweetness against lime’s sharpness for a balanced, not overly sweet profile.
• Orange Vanilla: Leans dessert-like, a creamsicle-style flavor that tends to divide people into strong fans and people who find it too sweet. The polar vanilla note here is smooth and warm, closer to real vanilla bean than artificial vanilla extract.
• Lemon: Polar’s classic citrus, clean and simple.
• Toasted Coconut: Polar toasted coconut brings a warmer, slightly roasted coconut note rather than a straightforward tropical flavor. It is one of the more unusual year-round options and a strong conversation starter.

What Is Unicorn Kisses Flavor?

Polar Unicorn Kisses is one of the most talked-about flavors in the Polar Seltzer Jr line. It is a kids-focused flavor sold in smaller 7.5 oz cans with bright, whimsical packaging. The actual taste profile of polar unicorn kisses is a blend of mixed berry and cotton candy notes, creating a sweet, fruity flavor that appeals to younger drinkers. Despite the playful name, the formula is the same clean ingredient list as the rest of the Polar lineup: just carbonated water and natural flavors, with zero sugar, zero calories, and no artificial sweeteners.

Does Polar Seltzer Have PFAS?

In a widely cited 2020 Consumer Reports investigation that tested 12 sparkling water brands, Polar Natural Seltzer Water came back with a PFAS reading of 6.41 parts per trillion, behind only Topo Chico. That was above the 1 ppt threshold Consumer Reports flagged as a concern, though still well under the older EPA guidance limit of 70 ppt.

Polar’s current official position is that ongoing monitoring shows no detectable PFAS, and the company publishes an independent report to back that claim. If PFAS levels are a factor in your buying decision, it’s worth checking Polar’s current reports directly, since water filtration technology has changed and improved over the years.

The 2025 \"100% Natural\" Lawsuit

In March 2025, a class action lawsuit was filed against Polar Beverages in California, arguing that its “100% Natural” seltzers contained trace synthetic compounds (such as ocimene quintoxide).

In July 2025, the federal judge dismissed the case, ruling that identifying a single synthetic compound was not specific enough, and that trace amounts do not make the “100% Natural” claim misleading to an average customer. As of now, there is no final ruling establishing that Polar’s products contain meaningful synthetic content.

Is Polar Seltzer Good for You?

For most people, yes. It’s zero calories, zero sugar, zero sodium, no sweeteners, and caffeine-free (outside the separate Frost line). Polar does not contain sugar of any kind, and it does use natural flavors derived from real fruit sources like lemon peel, vanilla bean, and mint leaves. It is certified kosher across the board, with several flavors specifically certified kosher for Passover (marked with the circle U symbol).

Like any carbonated water, the acidity from the CO2 suggests that drinking it with meals rather than sipping constantly all day is the best practice for tooth enamel.

Is Polar Healthier Than Soda?

Yes. A 12 oz can of regular cola contains about 39 grams of added sugar and 140 calories. Polar Seltzer contains zero grams of sugar and zero calories. The CDC identifies sugar-sweetened beverages as one of the leading sources of added sugar in American diets, and the Dietary Guidelines for Americans, 2025 to 2030, recommend that people reduce their intake of sugar-sweetened drinks. Swapping one soda per day for a Polar Seltzer eliminates that added sugar entirely while still giving you the carbonation and flavor variety that makes soda appealing in the first place.
