Curious about the culinary applications or safety of boiling carbonated water? It’s an intriguing question, as many wonder if our fizzy favorites will have different properties when heated.

This blog post will dive deep into what happens to carbonated water when boiled, its use in beverages like coffee and tea, possible risks associated with it, and some unique ways you can incorporate it into your cooking.

Hang tight! We’re about to bubble over with exciting information.

What Happens When You Boil Carbonated Water

Can You Boil Carbonated Water (1)

When carbonated water is boiled, it loses its carbonation and releases carbon dioxide.

Loss of carbonation

Boiling carbonated water causes a noticeable loss of carbonation. This happens because the heat prompts the compressed gas (carbon dioxide) dissolved in the water to expand and escape, leaving behind flat, non-fizzy water.

The high temperature breaks down the pressurized environment inside which keeps the bubbles contained, leading to rapid release of CO2 into air. Just imagine opening up a can of soda; that initial fizzle sound is actually CO2 escaping out! Only here, when boiling carbonated water, this process becomes faster and much more pronounced due to applied heat.

Thus, often after boiled treatment, your sparkling beverages end up losing their sparkle entirely!

Release of carbon dioxide

When you boil carbonated water, something interesting happens – the release of carbon dioxide. Carbonated water, also known as sparkling or fizzy water, contains dissolved CO2 gas that gives it its bubbly texture and refreshing taste.

When heated during the boiling process, this trapped gas begins to expand and rise to the surface, resulting in the characteristic fizziness being lost. The release of carbon dioxide can cause a loss of carbonation in the water, leaving it flat and less enjoyable to drink.

Using Carbonated Water in Coffee and Tea

Using carbonated water in coffee and tea can affect the flavor and may not be the best option, so it is worth exploring potential alternatives.

Effects on flavor

Boiling carbonated water can have an impact on the flavor of beverages like coffee and tea. When carbonated water is heated, it loses its fizziness or “sparkle,” resulting in a flat taste.

The bubbles that provide a refreshing sensation when drinking are released as carbon dioxide gas during boiling. This loss of carbonation can affect the overall taste and mouthfeel of your favorite drinks.

Additionally, some people may find that boiled carbonated water has a slightly altered or metallic taste compared to still water due to the chemical changes that occur when CO2 is released.

Potential alternatives

There are some potential alternatives to using carbonated water in coffee and tea:

  • Still water: Opt for plain still water instead of carbonated water when making your hot beverages. It won’t affect the flavor or texture.
  • Flavored syrups: If you’re looking for added flavor, try using flavored syrups in your coffee or tea instead of relying on the carbonation of the water.
  • Herbal infusions: Experiment with herbal infusions, such as chamomile or peppermint tea, to add a unique twist to your hot beverages.
  • Milk or cream: Consider adding milk or cream to your coffee or tea for a creamy and rich taste without relying on carbonated water.

Safety Considerations

Boiling carbonated water can be dangerous due to the risk of explosion, so it is important to avoid heating it.

Risk of explosion

Boiling carbonated water can pose a risk of explosion. When you heat the water, the pressure inside the bottle or container increases. If the pressure becomes too high, it can cause the container to burst and release hot liquid and steam, potentially causing burns or other injuries.

This is why it’s important to avoid boiling carbonated water and use still water for cooking and other purposes that require heating liquids. Stay safe by following this precautionary measure to prevent any accidents from happening.

Avoiding boiling carbonated water

To avoid potential risks and maintain the desired carbonation in your beverages, it is important to take precautions when boiling carbonated water. Here are some tips to keep in mind:

  • Use a separate pot: When boiling water for other purposes, such as cooking or making tea or coffee, use a different pot than the one containing carbonated water. This will help prevent any accidental release of carbon dioxide.
  • Let it go flat first: If you want to heat up carbonated water for a specific recipe or beverage, it is best to let it go flat before applying heat. Simply open the bottle and let it sit for a while until all the bubbles have dissipated.
  • Be cautious with heat: If you do decide to boil carbonated water, do so with caution. Keep an eye on the pot and use low to medium heat settings to minimize the chances of sudden expansion or pressure buildup.
  • Consider alternatives: If you’re concerned about losing carbonation or altering the taste of your drinks, consider using still water when boiling. You can always add sparkling water later if desired.

Can You Cook with Carbonated Water

Cooking with carbonated water can have interesting effects on food, enhancing flavors and textures in certain dishes.

Effects on food

Boiling carbonated water can have an impact on the taste and texture of food. When carbonated water is heated, it loses its fizziness and becomes flat, which can affect the overall flavor profile of dishes.

For example, if you’re using carbonated water to make a batter for fried foods or pancakes, the lack of carbonation may result in a less light and airy texture. Additionally, some recipes that call for carbonated water rely on its bubbles to create a specific texture or enhance certain flavors.

So, when boiling carbonated water for cooking purposes, it’s important to keep in mind that the end result may not be exactly what you expect compared to using still water.

In terms of specific effects on food, boiling carbonated drinks like soda or sparkling water can cause them to expand rapidly due to the release of dissolved CO2 gas. This rapid expansion could potentially lead to an explosion if precautions are not taken.

Recipes and recommendations

Here are some recipes and recommendations for using carbonated water in your cooking and beverages:

  • Try adding a splash of carbonated water to your fruit smoothies for an extra fizzy kick.
  • Use it as a replacement for regular water when making pancakes or waffles for a lighter texture.
  • Carbonated water can be used as a substitute for club soda or tonic water in cocktails like mojitos or gin and tonics.
  • Make your own homemade soda by mixing carbonated water with flavored syrups like raspberry or lemon.
  • Carbonated water can also be used as a base for marinades or sauces to add a unique touch to your dishes.


Boiling carbonated water has some interesting effects, such as a loss of carbonation and the release of carbon dioxide. It can also impact the flavor when used in coffee or tea. However, there are safety considerations to keep in mind since heating pressurized carbonated water could lead to explosion.

So, it’s best to avoid boiling carbonated water altogether.
