Decoding the Different Types of Carbonated Water
The most common alternative names for carbonated water are not always interchangeable, as they represent distinct products. The variations typically arise from whether minerals are added, if the bubbles are natural or artificial, and the overall origin of the water. Understanding these differences can help you select the ideal beverage for mixing cocktails, enjoying on its own, or aiding in digestion.
Seltzer Water
Seltzer is the simplest form of artificially carbonated water. It is simply plain water infused with carbon dioxide gas, with no added minerals or salts. Because of its neutral flavor profile, it is a versatile choice for a wide variety of mixed drinks and is often the base for flavored sparkling waters from popular brands like La Croix and Bubly. Home carbonation systems like SodaStream also produce seltzer when used with plain water.
Club Soda
Club soda is similar to seltzer but with one key difference: it contains added minerals. These minerals, which can include sodium bicarbonate, sodium citrate, and potassium sulfate, give it a slightly salty or mineral-like taste. This mineral composition is what makes club soda a favorite mixer for cocktails, as it can enhance and balance the flavors of other ingredients. While the difference in taste may be subtle, it can be noticeable to those with a sensitive palate.
Sparkling Mineral Water
Sparkling mineral water is water that originates from a naturally carbonated underground spring or well. As it travels through layers of rock, it absorbs minerals such as calcium, magnesium, and sodium, which contribute to its unique taste. The carbonation is either naturally present from the source or is enhanced during bottling. Brands like Perrier and San Pellegrino are classic examples of sparkling mineral water, each with a distinct flavor profile reflecting its mineral content.
Soda Water
This term is often used as a generic, catch-all name for any carbonated water. Historically, it referred to artificially carbonated water containing sodium salts, but its meaning has become ambiguous over time. Depending on the context, a bartender might interpret a request for "soda water" as seltzer or club soda. This is why it's helpful to know the more specific terms when ordering or shopping.
Decoding the Fizz: A Comparison of Carbonated Waters
To make the differences clearer, here is a breakdown of the primary types of carbonated water:
| Feature | Seltzer Water | Club Soda | Sparkling Mineral Water |
|---|---|---|---|
| Source | Artificially carbonated plain water | Artificially carbonated plain water | Natural underground spring or well |
| Additives | None; contains only water and CO2 | Added minerals (sodium bicarbonate, etc.) | Naturally occurring minerals |
| Taste Profile | Clean, neutral taste | Slightly salty or mineral taste | Flavor varies based on mineral content |
| Carbonation | Artificially added | Artificially added | Natural or artificially enhanced |
| Best For | Mixers, infusions, or drinking plain | Cocktails and beverages needing a salty edge | Enjoying on its own to appreciate its unique taste |
The History Behind the Bubbles
The history of carbonated water dates back to ancient times, with naturally effervescent springs being revered for their supposed healing properties by civilizations like the Romans. The modern era of carbonated drinks began in 1767 with Joseph Priestley, who invented a method to artificially infuse water with carbon dioxide. His discovery was later commercialized by Johann Jacob Schweppe, who founded the Schweppes Company in 1783 to sell bottled carbonated mineral water. This innovation led to the development of other carbonated beverages and mixers, forever changing the beverage industry.
Health Benefits and Considerations
For many, carbonated water serves as a healthier alternative to sugary sodas. It provides the satisfying fizz and effervescence without the calories or sweeteners. Research has also highlighted several potential benefits:
- Hydration: Plain carbonated water is just as hydrating as regular still water.
- Digestion: Some studies suggest that carbonated water can help relieve indigestion and constipation.
- Weight Management: The carbonation can increase feelings of fullness, potentially helping to curb appetite.
- Satiety: It may also help food stay in your stomach longer, contributing to a greater sense of fullness after meals.
However, it's important to note that some individuals, particularly those with sensitive stomachs or acid reflux, may experience bloating or discomfort from the carbon dioxide gas. Plain sparkling water is not a significant threat to dental health, but flavored varieties with added sugars or citric acid can pose a risk to tooth enamel.

How Carbonated Water is Produced
The process of carbonating water can happen in two main ways: naturally or artificially.
- Natural Carbonation: This occurs when water from a spring or well absorbs carbon dioxide from volcanic gas deposits beneath the earth's surface. Brands like Perrier and San Pellegrino source their water from these naturally occurring springs.
- Artificial Carbonation: The most common method involves injecting purified water with carbon dioxide gas under high pressure. This is how seltzer and club soda are made commercially. When the bottle is opened, the pressure is released, and the dissolved gas forms the characteristic bubbles.
Many consumers now make their own artificially carbonated water at home using countertop machines like SodaStream, which pressurize water with CO2 from a canister. This offers a convenient way to enjoy fresh, fizzy water without the waste of single-use bottles.
A Refreshing Variety
Today, the market for carbonated water is more diverse than ever. A quick trip to the grocery store reveals an endless array of options, from unflavored and crisp seltzers to heavily mineralized sparkling waters and artificially flavored beverages. Some of the most popular brands include:
- La Croix
- Bubly
- Spindrift (made with real fruit juice)
- Perrier
- San Pellegrino
- Polar Seltzer
- Topo Chico
- Waterloo
Conclusion
What is another name for carbonated water? The answer is more complex than a single word. While terms like seltzer, club soda, and sparkling mineral water all describe variations of this bubbly beverage, the key differences lie in their source, mineral content, and taste profile. Whether you're looking for a neutral mixer, a naturally mineralized drink, or a simple, refreshing fizz, understanding these distinctions will help you navigate the effervescent world of carbonated water with confidence.
