Fizzy drinks are everywhere. From high-end restaurants serving sparkling water in glass bottles to grocery store shelves packed with flavored seltzers, the popularity of carbonated water has exploded. But there’s a common point of confusion is seltzer the same as sparkling water?
At first glance, they look identical: clear liquid, tiny bubbles, zero calories. Yet, when you take a closer look, you’ll see real differences. Understanding these distinctions matters, especially if you care about taste, health, or even how much you’re spending. This guide will break down seltzer vs sparkling water in detail, covering their origins, nutritional value, uses, and what sets them apart.
What Is Seltzer?
Seltzer is plain water that’s artificially carbonated. Carbon dioxide is pumped into filtered water under pressure, creating bubbles. The result is crisp, fizzy water with a neutral taste. Unlike sparkling water, it doesn’t naturally contain minerals unless they’re added later.
Historical Origins
The word “seltzer” actually comes from Selters, Germany, a village famous for its naturally carbonated mineral springs dating back to the 16th century. Over time, American beverage makers adopted the term to describe artificially carbonated water.
Characteristics of Seltzer
- Neutral Taste: No mineral flavors; just water with fizz.
- Customizable: Can be flavored with fruit essences, oils, or natural flavorings.
- Affordable: Typically cheaper than sparkling water.
- Versatile: Commonly used in cocktails, mocktails, and as a soda substitute.
Popular Seltzer Brands
- LaCroix: Known for its bold, natural flavors like lime and grapefruit.
- Polar Seltzer: One of the oldest American seltzer brands, famous for seasonal limited-edition flavors.
- Spindrift: Unique because it uses real fruit juice instead of natural essences.
- Bubly (PepsiCo): Marketed as a fun, youthful alternative to soda.
What Is Sparkling Water?
Sparkling water is naturally carbonated water that comes from underground springs. Unlike seltzer, it contains naturally occurring minerals, such as calcium, sodium, and magnesium. These minerals influence both taste and health benefits.
Key Features of Sparkling Water
- Natural Carbonation: Some sparkling waters are naturally effervescent; others may be enhanced with extra CO₂.
- Distinct Taste: Minerals give sparkling water a subtle, sometimes salty or bitter flavor.
- Premium Image: Often imported from Europe, packaged in glass bottles, and associated with fine dining.
Well-Known Sparkling Water Brands
- Perrier (France): Iconic green bottle, sharp bubbles, and a bold mineral taste.
- San Pellegrino (Italy): Softer bubbles, slightly salty flavor, often paired with gourmet meals.
- Gerolsteiner (Germany): Rich in calcium and magnesium; one of the most mineral heavy sparkling waters.
- Topo Chico (Mexico): Cult favorite with a crisp, refreshing profile.
Taste Differences
Each brand tastes different because mineral composition varies by source. For instance:
- Perrier is crisp and sharp.
- San Pellegrino is smooth and balanced.
- Gerolsteiner is strongly mineralized, which some find too salty.
Side by Side Comparison
To make it easier, here’s a breakdown of the main differences:
| Feature | Seltzer | Sparkling Water |
| Carbonation | Artificial CO₂ added | Naturally carbonated (sometimes enhanced) |
| Mineral Content | None (unless added artificially) | Naturally contains minerals |
| Taste | Neutral, clean | Mineral-forward, distinct |
| Price | Affordable, everyday option | Premium, often imported |
| Best For | Cocktails, flavored varieties | Drinking plain, gourmet pairings |
| Brands | LaCroix, Polar, Bubly, Spindrift | Perrier, San Pellegrino, Gerolsteiner |
Carbonation Process: Artificial vs Natural
- Seltzer: Carbon dioxide is injected into water. The result is pure fizz without any natural mineral influence.
- Sparkling Water: Comes from natural springs where water picks up carbonation and minerals underground. Some brands reinforce bubbles with added CO₂ for consistency.
This difference impacts not just taste but also marketing. Sparkling water is often seen as “purer” and more “authentic,” while seltzer is positioned as fun and affordable.
Mineral Content and Flavor Profiles
The biggest flavor difference lies in minerals. Sparkling water contains sodium, calcium, magnesium, and potassium all of which alter taste. Some people love the complexity, while others prefer seltzer’s clean neutrality.
Example Mineral Levels (per liter):
| Brand | Calcium (mg) | Magnesium (mg) | Sodium (mg) |
| Perrier | 147 | 3 | 9 |
| San Pellegrino | 164 | 53 | 33 |
| Gerolsteiner | 348 | 108 | 118 |
| LaCroix (seltzer) | 0 | 0 | 0 |
As shown, sparkling waters carry significant mineral loads compared to seltzers, which are essentially mineral free.
Price and Availability
- Seltzer: A 12 pack of LaCroix costs around $4–6 in the U.S.
- Sparkling Water: A 12-pack of San Pellegrino or Perrier costs $12–15, nearly double or triple the price.
For budget-conscious shoppers, seltzer is the clear winner. For those looking for a premium dining experience, sparkling water delivers.
Health Benefits:
Both options are much healthier than soda, but sparkling water offers extra perks due to its minerals.
Shared Health Benefits

- Digestive Relief: Carbonation can reduce indigestion and nausea.
Unique to Sparkling Water
- Bone Health: Studies suggest calcium-rich sparkling water may support bone density.
