Sparkling Water Making Kit for Homemade Seltzer & Carbonated Waters — Soda Stream Alternative

This Soda Stream alternative home carbonating kit allows you to carbonate any beverage of your choice. Make your own sparkling water, soda, seltzer water, juice, beer or almost any other beverage you can think of using the sleek 2L, 3.6L, 5L or 8-liter Stainless Steel Single Handle Growler. You will need your own CO2 tank and gas line assembly with ball lock disconnect in order to pressurize this system.  If you have one of our other soda kits already, you can upgrade to this growler kit and your existing equipment will be compatible!

If you'd like a CO2 tank with your sparkling water kit, you can look at our complete sparkling water kit.

The Stainless Steel Single Handle Mini Keg comes in 4 different sizes:

  • 2L - 1/2 Gallon*
  • 3.6L - 1 Gallon*
  • 5L - 1.3 Gallons*
  • 8L - 2 Gallons*

* Appx volume

The kit Includes:

  • Selected Size of Stainless Steel Single Handle Growler with Travelling Cap
  • Carbonation Cap with Ball Lock Gas Disconnect and PRV
    - The carbonation cap is outfitted with a standard ball lock post to attach a ball lock disconnect to.

Carbonating sodas, seltzers, and any other beverage at home is extremely easy with this setup!  Everything you need to get started is included in this kit (all you need to do is get the CO2 tank filled - They ship empty by law). 

How to make homemade carbonated water:

(Recipe below for 2L Size)

  1. Fill your stainless steel growler with about 3/4 (1500ML) or a little more (you just need to leave a couple of inches of airspace), and screw on the top assembly.
    Make sure the liquid is ice-cold, this will help speed up the process of carbonating. CO2 absorbs into cold liquids much better than warm or room temp. 
  2. Set the pressure on your regulator to about 15PSI. 
  3. Attach the ball lock disconnect to the gas-in post. 
  4. Pull the pressure relief valve a few times.  This will purge out the oxygen inside the mini keg and replace it with CO2. 
  5. Increase the pressure on your regulator to 30-35 PSI and begin shaking the growler.  You will hear the CO2 forcing itself into the growler. 
  6. Do this for a couple of minutes - and you can shake the growler while carbonating to force the CO2 into the liquid faster.  
  7. After the liquid has been carbonated you can release the pressure from the mini keg by pulling the Pressure Relief Valve (PRV), unscrew the cap, and pour your carbonated beverage into a glass straight from the mini keg.  

Use in conjunction with our Soda Extract Flavors, or use your own soda recipe. We often use it around here to make sparkling water.

This is also great for carbonating sodas, and making your own homemade Topo Chico and other flavor-infused bubble waters!

Great Product! No hassle and as described

By Mike Y · February 6, 2020

Loving this carbonation system. My sodastream died on me and I was tired of paying for their proprietary CO2 refills. I heard about making your own rig for seltzer, but I didn't want to deal with the hassle of ordering all the right parts and connecting it up (I am handy but totally new to carbonation). I went out searching for a "kit" that would have everything I need to start carbonating out of the box. It is a huge bonus that this product is already assembled. All parts are securely fitted together with the correct tubing and adapters. Other than the time it took to go to my local homebrew place to get a CO2 refill the set up was as simple as screwing the regulator onto the tank and I was good to go!

Quality is all there. Brand new tank as advertised. Taprite regulator, and everything is solid.

As far as price it is really not that much more than ordering the pieces a la carte and assembling yourself so there really no downside and you don't have to worry about sketchy quality components or getting the wrong or excess fittings.

I have had a great time carbonating all sorts of beverages and getting comfortable with the system in general. Since this product uses all universal components I can build off of it in the future. I am already looking at making a kegerator type set up for my seltzer!

Worth the money as it's well made

By Ed · January 14, 2023

The other reviewer here already said a lot of what needed to be sent but as it's two years old let me add to it.

This kit came perfectly assembled requiring only a few nuts to be tightened and the tank I got was new and recently tested so it will be good for 5 years at my local CO2 provider.

The stainless steel cap is high quality and the build quality is flawless.

This is a much better option than a soda stream as it's much cheaper to operate over time and your helping the environment but now using a bunch of those expensive soda stream cartridges

Love these things! Beats the SodaStream

By Carb King · April 30, 2025

Since I’ve gotten this thing, I’ve been cranking out carbonated water. The ease of use of this has been great. My family loves it and it’s been saving us a ton of money over the soda stream. My kids love it so much that we just ordered another stainless growler so that they could make their own soda waters. Thanks a lot keg outlet!
