Soda Water vs. Sparkling Water: What’s the Real Difference in Your Fizz?

The choice between soda water and sparkling water often comes up in Australian households, but what’s the difference? Here’s a guide to understanding the differences between soda water, sparkling water and seltzer, breaking down the differences in composition, taste profiles and best uses.

Composition is Key: What Makes Them Different?

The difference between soda water (also referred to as club soda) and sparkling water largely comes down to the minerals in each. Both soda water and sparkling water are made by carbonating still spring water with carbon dioxide, meaning that both waters retain naturally occurring minerals. And while sparkling water includes these minerals and carbon dioxide, soda water also features added sodium bicarbonate and potassium sulphate so that it retains its fizz when mixed with other liquids, including alcoholic spirits. This, therefore, affects the flavour profile of soda water.

Soda Water vs Sparkling Water: A Simple Comparison

At a glance, here’s a look at the differences between soda water and sparkling water:

Taste Test: How Minerals Influence Flavour

The composition of soda water and sparkling water gives each beverage a different flavour profile. With the addition of sodium bicarbonate and potassium sulphate, soda water gains a slightly salty flavour that is slightly sharper on the palate. Alternatively, sparkling water has a cleaner, more neutral flavour profile because its main source of flavour is from the naturally occurring minerals of spring water.

Why Soda Water Tastes Saltier

Soda water tastes saltier than sparkling water because of the added sodium bicarbonate and potassium sulphate. These are added to spring water, alongside carbon dioxide, to balance the acidity and enhance the overall mouth feel of soda water. The punchy nature of the bubbly fizz of soda water comes down to these additives, making it ideal to use as a mixer.

Why Sparkling Water Tastes Neutral and Clean

Sparkling water tends to taste more neutral because carbon dioxide is the only additive. The flavour of sparkling water lies in the naturally occurring mineral properties of the spring water that is then carbonated. Plus, it should be noted that sparkling water is less carbonated than soda water, resulting in a more refined, less aggressive fizz.

When to Use Which: Mixers, Meals, and Refreshment

Thanks to the bold flavour profile and sharp fizz of soda water, it’s ideal for mixing with alcoholic spirits and cocktails. You’ll find soda water used in drinks, including vodka sodas, gin and sodas, as well as cocktails like an elderberry fizz. It’s also mixed with cordials and fruit juices to add pop to drinks that are appropriate for all ages.

Sparkling water’s lighter mouth feel and subtle flavour make it perfect for enjoying as a standalone drink. It’s a lovely palate cleanser alongside a meal, and can be enjoyed with a slice of lemon or lime, or a sprig of mint. It makes for a simple, sugar-free drink and is a popular accompaniment to lunch and dinner.

What About Seltzer and Tonic Water?

Seltzer and tonic water are other refreshment options and popular mixers for drinks. Seltzer is simply carbonated water with no added or naturally occurring minerals and is similar to what many home carbonation devices produce. Tonic water is technically a soft drink, not carbonated water, as it has quinine and other sugars and sweeteners added to it. Tonic water is classically served with gin in a gin and tonic.
