Can You Really Carbonate Soda Without a SodaStream?
Yes. People were carbonating soda long before countertop machines existed. Traditional sodas like root beer, cola, and ginger beer relied on natural carbonation through fermentation or by mixing syrup with already-carbonated water.
Instead of forcing CO₂ into liquid with cartridges, natural methods include:
- Allowing yeast to create CO₂ through controlled fermentation
- Utilizing fizzy seltzer water for instant soda
Carbonating soda without a machine:
- Uses simple, proven processes
- Requires no pressurized cartridges
- Works with everyday household tools
- Produces classic, old-school fizz
This makes it ideal for anyone curious about DIY soda carbonation or exploring soda fermentation at home without investing in specialized gear.
Natural Ways to Carbonate Soda at Home
If you want to learn how to make fizzy soda at home, there are several effective homemade soda carbonation methods. Craft a Brew’s soda kits are designed to support two of the most reliable options.
Option 1: Add Syrup to Seltzer Water (Recommended)
This is the easiest and most beginner-friendly way to make fizzy soda at home.
Once you have brewed your all-natural root beer or cola syrup, simply mix:
- 1 part soda syrup
- 3 parts seltzer water
You can use:
- Store-bought seltzer
- Sparkling water
- Water carbonated with any soda maker (optional)
This method:
- Creates instant carbonation
- Produces zero alcohol
- Allows precise control over sweetness and fizz
- Extends shelf life when syrup is refrigerated
This approach is ideal if you want consistent results without fermentation or monitoring.
Option 2: Bottle-Conditioned Soda (Natural Fermentation)
For those interested in all-natural soda carbonation, Craft a Brew kits also allow you to carbonate soda through bottle conditioning.
This method uses yeast to naturally create CO₂ after bottling, a classic example of soda fermentation at home.
How it works:
- Soda syrup is diluted with water
- A small amount of yeast is added
- Bottles are sealed so CO₂ becomes trapped
- Specialty pressure-regulating caps are used to prevent bursting
Over 12 to 24 hours, the soda naturally carbonates, creating a lively fizz.
This method:
- Produces authentic, traditional carbonation
- Adds depth and body to the soda
- Requires close monitoring
- Must use plastic 2-liter bottles only
Warning: Glass bottles should never be used for bottle-conditioned soda due to rapid pressure buildup.
How to Carbonate Homemade Soda Step by Step
Here is how Craft a Brew’s natural soda carbonation process works using bottle conditioning.

Explore Soda Recipe Kits.
Bottle Safely
Divide syrup between two clean 2-liter plastic bottles using
specialty bottle caps
.
Top with cool, filtered water, leaving 3 inches of headspace.
Add Yeast
Sprinkle 1/4 teaspoon of yeast into each bottle.
Seal and Ferment
Store capped bottles at room temperature (65 to 75°F) for 12 to 24 hours.
Monitor Closely
Check bottles every 6 hours. When firm like store-bought soda, refrigerate immediately.
Chill and Enjoy
Refrigerate for at least 12 hours before opening. Consume within one week.
A Note on Alcohol
Bottle conditioning uses yeast, which naturally produces trace amounts of alcohol. When followed correctly, alcohol content remains very low, around 0.5 percent.
If you want zero alcohol, use the seltzer method instead.
Craft a Brew soda kits are not designed to make alcoholic soda. Extended fermentation can increase pressure and risk. Always refrigerate promptly.
Tips for Getting the Right Amount of Fizz
Follow these tips to ensure consistent results:
- Monitor bottles frequently
- Keep bottles warm during carbonation
- Refrigerate immediately once carbonated
- Never use glass bottles for fast-fermenting sodas
