How To Make Carbonated Water

How To Make Carbonated Water

Carbonated or sparkling water is normal water including carbon dioxide. The high content of CO2 makes the water fizzy and gives it a peculiar taste. It is a tasty alternative to normal water.  

Though soda water is easily accessed in stores. Store-bought seltzer water contains harmful additives, sodium, acids, and preservatives that can affect your diet. It also increases plastic bottle use which is unfavorable to the environment.

The consumption of homemade carbon water can be comparatively cheaper than buying it in stores. It is also a healthy alternative to store-bought sodas as you can formulate your carbonated water with natural flavor preservatives.

Before You Begin

Here are some useful tips before you start making soda water on your own.

  • Use chilled water only as CO2 dissolves well with cold water.
  • Water with high chlorine content is not useful to make sparkling water.
  • Over carbonation can sometimes shatter glass containers. So, use a plastic bottle. 

How To Make Carbonated Water

Using Vinegar And Baking Soda

Vinegar And Baking Soda

The chemical reaction of vinegar and baking soda has a bubbly effect when mixed with water. The reactions produce carbon dioxide which is a key to making sparkling water. It is a cheap way to make seltzer water without any machine.


  • Drill bit
  • Two bottles
  • A tube
  • Vinegar and baking soda
  • Scissors
  • seal tape


  1. Put water into a bottle and fill another container with vinegar and baking soda mixture.
  2. Using a drill bit, make holes in both soda bottle caps. The hole should be smaller than the size of the tube.
  3. Put each end of the tube on both bottles.
  4. Use seal tape to secure the tubing into place.
  5. Shake both bottles vigorously. The bubbles will start to appear. Stop shaking after the bubble disappear.
  6. Let it sit for two minutes.
  7. Add natural ingredients like mint, lemon, or orange, and enjoy your homemade carbonated drink.

With Dry Ice

Dry ice is frozen carbon dioxide. Putting dry ice into the water results in it releasing carbon dioxide into the water. It will make the water fizzy with bubbles. However, it comes with its drawbacks. It is better to take precautions before starting the process.

  • Don’t touch dry ice with bare hands. Use gloves or spoons for the recipe.
  • Follow this method in an open or well-ventilated area.


  • Dry ice
  • Spoon or gloves
  • Water


  1. Drill holes into the bottle cap.
  2. Pick up dry ice with gloves or a spoon and put it in a jar.
  3. Put the dry ice into the water and screw it with drilled cap
  4. Let it sit for 10 minutes.
  5. Stir it well until the ice dissolves.
  6. The reaction will lead to vaporization
  7. Finally, you have your carbonated water at home.

Using Yeast

Yeasts produce carbon dioxide and alcohol when it eats sugar and turns it into energy. This process is well known as fermentation. Yeast is a good alternative to make seltzer water. For this method:


  1. Pour water into a 1-gallon bottle with space for air in the container.
  2. Add 1/8 tablespoon of yeast into the water.
  3. Shake it well for 1 minute until the dry yeast dissolves.
  4. Leave the solution for 12-48 hours according to your room temperature.
  5. Put the mixture in the freezer to stop the fermentation process.
  6. Drink the carbonated water however you like after.

With Seltzer Bottle/Soda Siphon

Seltzer Bottle/Soda Siphon

If you own a seltzer bottle or soda siphon then, it is one of the easiest ways to make carbonated soda. A soda siphon or seltzer bottle uses CO2 cartridges instead of CO2 tanks to make sparkling water. It is portable and easy-to-use equipment. You have to buy a CO2 charger separately. Make sure to buy one that fits the bottle. Follow the manufacturer’s instructions before making seltzer water.


  • Seltzer bottle
  • CO2 charger


  1. Fill the bottle with cold water.
  2. Screw the top tightly after the bottle is full.
  3. Insert the CO2 charger into the bottle cartridge holder.
  4. Push the pressing handle to release gas into the water.
  5. Shake the bottle.
  6. Replace the cartridge with the cap.
  7. Finally, serve sparkling water into the cup. 

Seltzer bottles are being replaced by soda makers nowadays. It is way easier than a soda siphon. But it is expensive comparatively.

Using Soda Maker

It is a modern way to make seltzer water at home. You will need a soda maker that you can purchase in stores or order it online. You can different flavors to the water to make it more interesting. This equipment includes carbonation or CO2 cartridges that adds carbonation to the water.

Soda Maker


  1. Unscrew the cap of the carbonation bottle.
  2. Take off the back of the soda machine. Some soda maker cylinder holder is designed where you can put the cylinder from beneath the equipment.
  3. Place the carbonator into the machine and screw it three times in a clock way position.
  4. Put the cover back into the machine after you hear a clicking sound. 
  5. Fill up the soda bottle with chilled water with any extra ingredient you may want to add.
  6. Screw the bottle into the bottle lock.
  7. Press down the bottle after placing it in a vertical position.
  8. Stop the process by pressing the stop button. You can limit the level of carbonation.
  9. Pull out the bottle from the soda maker.
  10. You can add flavors or other ingredients to the water before you serve it. 

DIY Carbonation System

If you have ideas and tools to make a carbonation machine. You can make it on your own in your space. With this technique, you can adjust the C02 pressure limit however you want it to. 

DIY Carbonation System

Here is some precaution before you start the setup:

  • Inhaling excess CO2 can lead to respiratory issues. It is better to assemble the tank in an open space.
  • Turn off the valves of the regulators before starting the setup.
  • Make sure the tank is out of reach for kids and pets. It can lead to tip-over accidents.


  • CO2 tank
  • A dual gauge gas regulator
  • Vinyl tubing of inner diameter 5/16 inch.
  • A ball lock keg coupler
  • Carbonator cap adapter
  • Soda bottle
  • Plumbers tape
  • Screwdriver


  1. Attach the regulator to the CO2 tank.
  2. Wrap the plumber’s tape around the threads of the CO2 tank a few times so that it would not leak.
  3. Insert the compression ring into the regulator and screw it tightly. But not too tightly.
  4. Screw 5/16 inch barb onto the Ball lock. 
  5. Cut an adjustable length of hose that will go through the regulator and ball lock. 
  6. Put the hose clamp on both ends of the tube.
  7. Attach one end of the tube to the regulator, all the way to the barb. 
  8. Tighten the hose clamp using a screwdriver. 
  9. Again tighten the hose clamp on the Ball-lock barb.
  10. Make a soda bottle with chilled water ready for the next step.
  11. Turn on the regulator and adjust the outflow PSI up to 30-40.
  12. Squeeze the bottle to remove oxygen out of the bottle. Screw the bottle with the carbonation cap after the bottle is full of water with no air. 
  13. Press the ball lock over the carbonation cap.
  14. Turn the bottle upside down and shake it well for 30 seconds.
  15. You will observe the water carbonating with bubbles to fewer bubbles. 
  16. Remove the ball lock and carbonation cap.
