Can You Re-Carbonate Flat Soda? Tips & Tricks
Can you re-carbonate flat soda?
To answer plainly: yes, you can re-carbonate soda that has gone flat. At its core, soda is simply carbonated water with added flavors and sugars. Re-carbonating would mean adding fresh CO2 to fizz up the soda again. However, it's important to note that the taste and texture of a re-carbonated soda may not be exactly the same as a freshly opened one.

When you pop open a bottle of your favorite soda, there's nothing quite like the satisfying hiss of escaping gas. Unfortunately, this fizz can quickly diminish if the soda is left uncapped, leading to a flat beverage devoid of its signature bubbles.
Whether you're buying your soda in the store in cans, or making it from home, this guide explores the possibility of restoring life to your soda, offering practical tips and methods to re-carbonate flat drinks, ensuring that you can enjoy that crisp sensation once more.
3 Ways to re-carbonate flat soda
- Using a soda maker
- Using dry ice
- Using a whipping siphon
Before you pour that flat soda down the train, there are simple methods to bring back that beloved sparkle. Re-carbonating flat soda at home is a cost-effective, sustainable, and fun experiment. Here are three methods you can try:
Using a Soda Maker
- Pour the flat soda into the soda maker's bottle, filling it up to the designated line.
- Securely attach the bottle to the soda machine*.
- Press the carbonation button to your desired level of fizz.
- Once carbonated, remove the bottle and gently swirl the soda to distribute the bubbles evenly.
*Note: This method requires a soda maker with a removable carbonating head which is integral for cleaning.
We do not recommend re-carbonating sodas or beverages with sugar or flavoring in a standard machine with the carbonating head attached to the soda maker.

Using Dry Ice
- Crush a small amount of food-grade dry ice into fine pellets.
- Gently add the pellets to the flat soda in an open container, allowing the CO2 to blend in.
- Stir gently and let the dry ice fully dissolve.
- Once the soda is fizzy, pour it into a serving glass and enjoy.
Using a Whipping Siphon
- Pour the flat soda into the whipping siphon's canister, not exceeding the maximum fill line.
- Charge the siphon with a CO2 cartridge by following your device's instructions.
- Shake the siphon gently to mix the gas and liquid.
- Release the carbonated soda into a glass and enjoy its renewed fizz.
Common questions about re-carbonation
When does soda lose its fizz after being opened?
Soda generally begins losing its fizz soon after the can or bottle is opened due to the escape of carbon dioxide gas which was initially dissolved under pressure. The rate at which soda becomes flat depends on several factors, including exposure to air, temperature, and whether the container is resealed.
Warmer temperatures and increased exposure to air can accelerate the loss of carbonation. Studies show that storing soda at cooler temperatures and in tightly sealed containers can help retain carbonation longer.
Can you use a CO2 tank to re-carbonate soda?
Using a CO2 tank is an effective way to re-carbonate soda. You'll need a carbonation cap that fits the bottle, enabling direct CO2 injection. This technique allows precise control over carbonation levels, but it requires the right equipment and adherence to safety precautions.
How long does re-carbonated soda stay fizzy?
The duration for which re-carbonated soda remains fizzy can vary based on how it's stored. For best results, it should be kept in a sealed container and stored at a cool temperature to maintain its fizz longer.
Does re-carbonating soda change its taste?
The process of re-carbonating soda might lead to a slight change in taste due to the interaction with CO2. Additionally, any added flavors may become more subdued or slightly altered, but generally, it should still remain quite enjoyable.
Summary
Re-carbonating flat soda is a feasible way to restore its fizz and enjoy it anew. There are several methods to achieve this, including using a soda maker, dry ice, or a whipping siphon, each offering a unique approach to reintroducing CO2 into the beverage.
While the taste of re-carbonated soda might not exactly mirror that of a freshly opened bottle due to the interaction with carbon dioxide, it nonetheless provides a refreshing experience. Additionally, proper storage techniques can help prolong the fizz of both freshly carbonated and re-carbonated sodas.
