Is Soda Water the Same as Sparkling Water?

by Dr. Jonathan Doyle - Updated February 26, 2025
If you’ve ever stood in the drinks aisle of a supermarket, staring at bottles labelled “Soda Water” and “Sparkling Water,” you may have wondered: are these two drinks the same thing? After all, both are bubbly, refreshing, and commonly used as mixers for cocktails or a fizzy alternative to still water. But are they truly interchangeable, or is there a key difference between soda water and sparkling water that you should know about?
In this blog post, we’ll dive into the bubbles and explore the differences between soda water and sparkling water, taking a closer look at their composition, uses, and health implications. Whether you’re a fan of fizzy drinks or just trying to make an informed choice, keep reading to get the full lowdown.

What Is Soda Water?

Soda water, also known as carbonated water or club soda, is water that has been carbonated (i.e., infused with carbon dioxide gas). This creates the effervescence (bubbles) we associate with fizzy drinks. However, what sets soda water apart is that it usually contains added minerals, such as sodium bicarbonate (baking soda), potassium sulfate, or sodium chloride. These minerals can give soda water a slightly salty or alkaline taste.
Historically, soda water was used for medicinal purposes and was often prescribed to soothe stomach ailments or as a mild digestive aid. In modern times, it’s mainly used as a mixer for alcoholic beverages like gin and tonic, as well as a refreshing beverage on its own.

What Is Sparkling Water?

Sparkling water is simply water that has been carbonated. Unlike soda water, sparkling water typically doesn’t contain any added minerals. The bubbles come from dissolved carbon dioxide (CO2) gas, which creates a refreshing effervescence. Sparkling water is typically flavour-neutral, with a crisp, clean taste that most people enjoy on its own or in a drink mix.
Sparkling water is often bottled directly from natural springs or mineral sources, giving it a naturally occurring fizz and sometimes even a unique mineral profile. Some brands, however, carbonate the water artificially.

Key Differences Between Soda Water and Sparkling Water

Mineral Content

One of the most significant differences is the presence of minerals. Soda water has added minerals that can give it a salty or slightly bitter taste, whereas sparkling water is usually mineral-free or contains naturally occurring minerals.

Taste

Because of the minerals added to soda water, it can have a slightly different taste. Sparkling water, on the other hand, tends to be crisp, clean, and neutral.

Uses

Soda water is often used as a mixer for cocktails or in recipes where the slight mineral taste complements other ingredients. Sparkling water, with its clean taste, is more commonly enjoyed on its own or in beverages where you don’t want any additional flavour altering the drink.

Health Impact

While both soda water and sparkling water are low in calories and have no sugar, soda water’s added minerals may be a consideration for those watching their sodium intake. For most people, this isn’t a problem, but it can be something to keep in mind if you’re sensitive to sodium. Sparkling water is typically a healthier, pure option since it has fewer additives.

Carbonation Levels

The level of carbonation can vary between soda water and sparkling water. Soda water typically has a strong fizz due to added carbon dioxide, while sparkling water’s level of carbonation can vary depending on how it’s made.

When to Use Soda Water vs. Sparkling Water?

Soda Water Uses

  • Cocktails : Soda water is a popular mixer for gin and tonics, whisky sodas, and other mixed drinks. The added minerals can complement alcoholic beverages.
  • Cooking and Baking : It’s sometimes used in recipes that require a little extra lift, like in batters or dough.
  • Medicinal : Historically, soda water has been used to soothe stomach discomfort, but that’s a less common practice today.

Sparkling Water Uses

  • Hydration : Sparkling water is a great way to hydrate while enjoying a little extra fizz. It’s an ideal choice if you’re trying to cut back on sugary sodas.
  • Refreshing Beverage : Sparkling water is great on its own, especially when chilled or paired with a slice of lime or lemon.
  • Mixing in Cocktails : Sparkling water can also be used as a mixer in cocktails, particularly in drinks that don’t need the extra mineral taste found in soda water.

Conclusion: Are Soda Water and Sparkling Water the Same?

While soda water and sparkling water both provide a bubbly, refreshing drinking experience, they are not the same thing. Soda water contains added minerals that give it a unique taste, while sparkling water is typically plain water carbonated without any added minerals or salts. The differences in taste, use, and health considerations mean that while they are similar, they are not interchangeable in all cases.
