Instead of CO2 tanks, it uses CO2 cartridges to carbonate water. It is ideal for people who drink carbonated water occasionally and would not want to use CO2 tanks. Portable and simple to use, it is also perfect for on-the-go and outdoor applications. Currently, using a soda maker is the most common way to make sparkling water at home. Soda makers or sparkling water makers are easily accessible nowadays with the many companies offering them.
They are safe to use, easy to set up, and efficient, giving you the freedom to have sparkling water any time you need. If you are a frequent drinker of carbonated water, investing in one of these machines is a good idea.
This method requires you to make your very own carbonation machine. If you have the time and tools and love doing DIY projects, then this method is the best way to make sparkling water at home. Although some parts can be a bit pricey, a DIY carbonation system will prove to be cost-effective in the long run. Compared with soda maker machines that are commercially available, DIY carbonation systems can be more versatile.
You can install adjustable CO2 regulators that will allow you to fine-tune the carbonation level in your water instead of being stuck with factory-set ones that have a predefined pressure limit.
Note: Work on this project in a well-ventilated space as a high concentration of CO2 may cause severe breathing problems. Screw the cover back on. Unscrew the cover on the other bottle. Leave the cover off. Grab one square of toilet paper. Put about a tablespoon of baking soda on it. Then fold the toilet paper up as indicated in the pictures.
First, make sure the cover on the to-be carbonated beverage is tight. Hold the Cover to the bottle with the vinegar in one hand and the toilet paper wrapped baking soda in the other hand. Drop the toilet paper baking soda roll into the vinegar. Screw the cap on as quickly as possible. Shake the bottle. Grab the bottle with your drink and shake it vigorously. You will notice bubbles coming out of the tube. Thats the CO2 that will carbonate your drink.
Keep shaking to disperse the CO2. Shake until there are no more bubbles coming out of the tube. Shake one more time and let sit for a minute or two. It is time to open the drink! First pinch the tube above the bottle. Pinching the tube will prevent a ton of CO2 form coming out of the other pressurized bottle.
If you don't do it, your drink will spray everywhere and probably lose its fizz. While pinching the tube, slowly open the bottle with your drink. Now bring the other bottle with the tube still pinched to the sink and release it. You will notice a ton of CO2 escaping, sometimes the vinegar, baking soda, toilet paper mixture will come out too.
Thats why you should do it over the sink. There are several benefits to soda siphons, starting with the fact that they are one of the most portable options on this list. They are also on the more affordable side as far as CO2 tank substitutes go.
Still, the price can start to stack up over time. Soda siphons are best for those who want an occasional drink of sparkling water without paying a huge amount of money for a professional CO2 tank. If you want sparkling water for picnics and other outdoor eating opportunities, soda siphons are a great CO2 tank substitute. Fill one bottle with water and the other with vinegar.
Now comes the strangest part. This is definitely a more science project-esque way of making carbonated water minus the traditional CO2 canisters. This is another MacGyver-worthy way of producing carbonated water without the tanks. Unlike the more roundabout method involving baking soda and vinegar, however, dry ice is frozen carbon dioxide and thus involves a much more direct method of creating it.
All you need to do is add one pound of dry ice to one gallon of water, stir, and voila. Oh, I am:- already planning to get one. I want to put it in a very small bar fridge. I am quite impressed but this little device. You need to add the Big Mac motor carbonator system, I just installed one in my kitchen, best thing ever, Seltzer on tap unlimited amounts.
Took me around a week to find all the parts and fittings, really worth it. Hi Alejandro, thanks for this valuable piece of information. I am definitely going to investigate and hopefully test it out. Not having to deal with refilling water tanks is a welcome upgrade.
Besides, you can get away with a much smaller fridge to keep the water cold. Single line out to dispensing tap sitting outside the fridge. Easily keeps up with my 4L a day, I suspect I could even do 6 or 8L. So not the sacrifice of fridge space, but still cupboard space.
Would be cheaper to run though than keeping 9L cold — not sure if trivial though. Plus I can detach the 9L keg in seconds, take it straight to a party with the dispensing tap with some 16g CO2 cartridges to dispense. Is there a problem with getting the water to mix in time? My SodaStream carbonates in 2s so it seems like it should be possible? A C02 carbonation system is a closed system.
In it, you have a balance between CO2 gas pressure and the amount of CO2 dissolved in water, which is also a function of temperature. As soon as you open up the tank to a water source, you will be making it a part of the system. It will affect the temperature inside the keg and the carbonation.
In essence, you will be carbonating your water source as well. I am not an engineer so I may be wrong about this, but what you are looking for is not technically possible. Not easily anyway. Hi, thanks again for your detailed instructions on making carbonated water. I finally got started on my and decided to buy a kegerator instead of making my own. Have a couple questions though. Will it hold its carbonation for awhile? I was wondering because I have a double tap, and may want to put a keg of beer in there sometimes.
You see, when you let some water out of the keg, the extra headroom will have to be filled by gas. It will come from either the CO2 tank, or from the water. If no CO2 is supplied at 40 PSI, the more water you draw, the more CO2 will leave the water to fill headspace, the less carbonated water will become. Yes, you can. Will it hold the same level of carbonation? No, if the room is warmer than the fridge.
Carbonation level measured in volumes or grams per liter is a function of pressure PSI and temperature. If you carbonate your water to 5 volumes at 40F and move the keg to 70F warm room, over time the carbonation level will drop to what it would have been if you carbonated at 40 PSI and 70F, roughly 3. How quickly will it happen? About as quickly as it carbonates. So, if you carbonate over 48 hours, it will take about 2 days to decarbonate to the point wheRE the carbonation stabilizes.
I once fully carbonated a keg of cold water in 25 or so minutes by shaking it and rolling it around. Would this keg system work outside of a fridge? Stephanie, yes, this system will work outside of a fridge.
However, you need to keep a few things in mind. You are correct to suspect that water may not effectively carbonate. It depends on your ambient temperature and the level of carbonation you want to achieve.
But you can design the system with that in mind, so it will. For example, we carbonate our water at 40F and 45 PSI. This results in about 5. We settled on this temperature and carbonation level after some experimenting and consider this ideal for our taste. On the other hand, Perrier, favorite carbonated water of many I used to love it too , carbonate their water to 3.
To get 3. To get 5. If you go the high pressure regulator way, make sure that the C02 hose is also rated to support that pressure. Unfortunately it is difficult to find components that allow a CO2 tank to be hooked up to the sodastream refills. The paintball containers are too small and need to be refilled too often.
Has anyone found a reliable attachment for the Sodastream cylinders to be able to fill them from a CO2 food grade tank? Thank you so much for this thorough write up. I just purchased 2 new corny kegs and all the supplies I needed to set up a home carbonation system.
Very excited. ONe thing you did not mention that I am now wondering about. How do you initially clean the new corny kegs and also, once your keg is empty again, do you first clean and sanitize it before you refill with water?
Thank you so much. You prepare the solution as per the instructions on the container, fill up the keg, let it sit for 30 minutes then rinse with water several times.
I push the solution and later the water out with CO2 to make sure the tubing gets cleaned up too. The same cleaner is commonly used to clean kegs later on, especially if you use them for beers, ciders, etc. This is what I do. Though, my kegs new, Italian made came pretty clean and I did not detect any oil residue inside or outside. Never used it but heard a lot of good feedback. After the initial cleaning and sanitizing I repeat the process very infrequently, maybe once a year or even longer.
The reason is that we use RO filtered re-mineralized water, without any flavorings. There are no sediments or residue as a result. Both kegs and the water stay cold in the fridge. Carbonation drops pH. All of this pretty much prevents any bacteria growth. Joel, no, there is no min or max length requirement unlike when dispensing beer but keep in mind that whatever length you plan on having outside of the kegerator the water in it will get warm. So, does this sparkling water keg have to be plumbed to a water line?
Or do you fill the water tanks individually when need? Tyler, this is an interesting question and I think someone already asked me about the same thing a while ago. The simple answer is that you have to fill the tanks then pressurize them with compressed C The cold plate will need a source of ice as well.
This is what feeds commercial soda fountains, soda guns at bars, etc. Thanks for the info, Jason. Where exactly in the Danby 4. My beer tower will be located on a quartz countertop above the fridge. Hi Brian, apologies for the later response, your comment was lost in the pile of spam comments. If your tower will be raised above the fridge, you might as well drill a smaller perhaps 1 inch hole in the top of the fridge similar to where I did and run both gas and water lines through it.
Plug any remaining open space with some insulating material. Alternatively, run the water line through the top and the gas line through the bottom, making holes just big enough for the lines to fit through, then cover any cracks with silicone.
You can see what I did on the picture under Update on July 3, You can also see more details in my kegerator build post. Lots of good info. I too was considering making my own carbonation system and like a lot of my projects — my wife got fed up with waiting for it and bought a Soda Stream.
Now that we have one I was wondering about how it works. On the Soda stream the bottle is removed after pressurizing and is open to atmosphere until you put the cap on it. Perhaps for safety reasons? Maybe having a lot of CO2 escaping in the process was better than dealing with a pressurized caps?
One other thing I noticed. Is a paint ball CO2 beverage grade? Hi Wentworth, the reason for that two-fold. For big companies like Soda Stream, saving even a penny per unit adds up to a large sum at the end of the day.
Think of CO2 gas as another soluble ingredient, like salt. Put a bunch of salt in water, stir — and it will get dissolved. Let the salted water stand for a while, and some of that salt will solidify again and become a sediment. The same is true with CO2 gas. It will get dissolved in water, much like salt.
To reverse, it will take time. The higher the pressure, the colder the water, the larger the area of contact between the water and the CO2 gas, the higher the rate of carbonation will be. The reverse is true too. In reality, you are only decreasing the pressure to the level of atmospheric pressure. It will take hours for the water to loose all that carbonation in those conditions. Put a cap on the bottle right after carbonation and little of it will be lost.
Refrigerate the bottle and even less will be lost. Leave no head space, cap on, refrigerate, an barely any carbonation will be lost. I do know that many people use conversion kits and refill at those places. You need to ask at those places. The purity of CO2 gas they use will likely vary from place to place. You bring up a very good point though. When refilling soda stream or other gas tanks, one must always inquire about the quality of the supplied CO2 gas.
Have you ever carbonated directly to glass? Seems like carbonating into a glass San Pellegrino container should be safe, no? Is it possible using the carbonator system to bottle quickly enough to preserve the carbonation and then be able to store it at room temp.
Is it possible to literally use the carbonator system and then cap them by hand and have a effective tasting water? This would be for 12oz glass bottles using crown caps. Jeff, bottling water and manually capping by hand will be just as effective as any mechanical method. It helps to think of carbonated water as water in which CO2 gas is dissolved. The level to which CO2 is dissolved in said water is a factor of 1 temperature and 2 pressure. It also helps to realize that carbonation and de-carbonation process is fairly slow on its own no shaking or other physical intervention.
Once in a bottle, at room temperature, the water temperature will go up, forcing CO2 out of the water. The pressure drop will also cause the water to lose carbonation. The two are connected and will try to find equilibrium. Fill that bottle half way and you will notice a significant drop in carbonation over time — CO2 will be forced out of the water to fill out the head space until the pressure in the head space and the water are equal.
In practical terms, I can only speak to storing carbonated water in double walled beer growlers. We use three of those at home, one 64oz and two 32oz ones. I fill them out all the way to the top and the water. When I open mine typically hours later, sometimes even longer than that, the water is still cold and fully carbonated.
Towards the end of the day as the water is consumed, the carbonation level drops but you still get a fairly decent amount of carbonation. In plastic bottles, as the water is consumed, you will be losing carbonation at a faster rate as the water will be increasing its temperature much faster than in a insulated beer growler. The timeline assumes room temperature water to start and no assistance like shaking or using carbonation stones.
If the water is cold — 40F or below I can fully carbonate a keg by slightly underfilling it and shaking for minutes. I did it a few times then got a second keg — problem solved.
If you do, pressure will fall as water is consumed, leading to lower water pressure at the tap progressively slower pours and loss of carbonation. Oh, I see. The tricky part is have it fit in the system, large or small, not interfere with carbonation process, cleaning, making sure the water is purified in time, etc. Too many variables. And like you said, they are quite large. My preferred choice is to use clean water to fill the tanks so I have no need to incorporate carbon filtration into the system.
However, there is an easy solution, you can simply use the carbon stick to remove impurities from the water before using for carbonation. I built The Carbonator rig as described in this article and it works great! I carbonate at about 45 PSI.
My technique is:. Pre-chill water in fridge to just above freezing. Apply carbonator cap loosely, burp air out of the bottle, and tighten cap. Carbonate at 45 PSI, shaking gently for 20 seconds.
Loosen carbonator cap and burp CO2 out of bottle. Re-tighten cap. Continue carbonating, shaking gently for 15 seconds. Remove carbonator cap and cap bottle and return to fridge. A very refreshing drink, indeed. Turns out this is really easy to do, and the payoff is well worth it. Carbonating individual Awesome to hear that, John. Thanks for the feedback on your experience with building your carbonator. Sort of like the Kishu charcoal you see in water pitchers.
Well, it is a part of the chain, not the carbonation system. I use RO water which uses a charcoal filter as one stage. In the system itself it will be tricky. I think I got all my supplies ordered using your guide. Thanks a TON! Quick question about filling the kegs. Is it important to fill the kegs completely full of water to eliminate any non-C02 gases?
No, not important in any significant way. Shaking the keg will give you the quickest carbonation, but if have a two keg setup like mine that is not an issue. Using a carbonating stone will also speed up the process but it a bit involved, not set it and forget it. Thanks so much for this great guide. If i buy the Edgestar kegerator like you have listed in your post, it looks like I could fit 2 sixth kegs in it.
How much more modification would I need to do to make it a relatively seamless dual system so I never have to wait 48 hours.
