The Fast Method – To carbonate quickly you need to go through all the above steps. However, your beer is ready to drink in as little as 1-2 days! The secret is to pre-chill the beer (CO2 mixed faster in cold liquid), keep the CO2 pressure in the cylinder at 30psi and to agitate the keg to mix the gas and liquid.
For the fast method, lay the keg on its side and rock it back and forth for 2-3 minutes to mix the CO2 gas in the headspace with the beer. Then disconnect the CO2 valve and put the keg in the refrigerator to settle for at least half an hour. At this point, you can test the beer. If you’re happy with the carbonation, you’re done! However, depending on the beer you may need to repeat this process several times over a day or so to get just the right carbonation.
If you’d rather watch a video than read, this video created by the team at Craft Beer and Brewing is a great resource that describes the process step by step.

How much CO2 does it take to carbonate beer?
Here’s a formula to estimate this using my findings Let’s assume 2.5 volumes and 5 gallons of beer That’s 3.24 ounces (weight) of CO2. That means one lb of CO2 should carbonate 4.93 (5 gallon) kegs of beer.
Do you need CO2 to carbonate beer?
Have perfectly carbonated beer every time. One of the joys of kegging your beer is not having to endlessly clean bottles or them occasionally exploding in your garage. Force carbonating is also another advantage of kegging, allowing you to carbonate faster and without the sediment found in the bottom of the bottle when naturally carbonating.
- Of course you can naturally carbonate in a keg by adding the correct amount of sugars and keeping it warm for about two weeks but most people prefer to ‘force’ the carbonation into the beer using a CO2 cylinder.
- Contrary to some people’s beliefs, force carbonating does not affect the head retention or size of the bubbles in the beer, CO2, once dissolved into the beer is the same weather it comes from a cylinder or produced by the yeast.
Although the principal is the same, there are many different techniques to carbonate in a keg. There are three 4 main factors at play when force carbonating, pressure, temperature, surface area and time. Pressure and temperature are both related and determine the carbonation level of the beer.
Typical beers will have a carbonation level around 2.4 – 2.6 volumes of CO2 by less common styles can have much higher or lower carbonation. The higher the temperature of your beer the higher the pressure will need to be inside the keg to achieve the desired carbonation level. The table below shows the pressure required to achieve your desired carbonation depending on the temperature.
Obviously the whole keg won’t be carbonated as soon as you set this pressure on your regulator. Over time the beer will approach the carbonation level determined by the pressure and temperature depending on the surface area to volume of the keg. Shaking the keg or using a carbonation stone effectively increases the surface area hence reduces the time.
Can you have too much CO2 in beer?
How Over Carbonation Happens – Over carbonating a beer is something that should only really happen if you are careless.9 out of 10 times, it is due to sloppy measuring of corn sugar or mistakenly setting the keg’s CO 2 regulator too high. That other 10% of the time is usually because of the dreaded infection,
How many grams of CO2 does it take to carbonate a keg?
Depending on temperature and carb levels, to carb and serve a 5 gal keg should each take about 60-80 g of CO2.
Why isn’t my beer carbonated?
I made a batch of Mexican beer that I primed with 1 tsp. per 16 oz. bottle. After 45 days, but the beer is flat. The taste is OK, but no bubbles. Can I reprime it? Why is my beer not carbonating? Name: Bruce State: Montana —– Hi Bruce, As you probably know, beer carbonates in the beer bottle when the yeast in the beer is given an extra dose of sugar (known as priming sugar ).
- The beer yeast is not consuming the priming sugar due to lack of time or cold temperature,
- The beer yeast does not have enough sugar to convert into CO 2, or
- The beer bottles are not thoroughly sealed.
If you used 1 tsp. of corn sugar per bottle, that should be sufficient. However, if you primed with dried malt extract, this may not be enough to produce the desired carbonation level. Either way, before you re-prime the flat beer bottles, I would recommend troubleshooting this flat beer in the following order.
First, ensure that your flat beer bottles have been sitting in a room with a steady temperature of 70°-75°F. Temperatures lower than this could cause the beer to carbonate very slowly or not at all. Keep in mind that certain closets and storage areas may not be as warm as the rest of the house. If you suspect that the beer bottles were in a cooler storage room, move them somewhere warmer and wait another two-three weeks. By the way, when someone ask: “why is my beer not carbonating?” this is by far the most likely the solution to the problem.
Second, check that all of the bottles of flat beer have been capped securely. If there’s any kind of leak, the CO 2 pressure may be escaping. This could be happening if you’re using twist-off beer bottles instead of pop-off beer bottles. Maybe it was just the first bottle you opened that didn’t have a good seal?
If the first two actions didn’t fix the problem, then you can re-prime the bottles of flat beer. I would only do this if you are certain that the bottles have had at least six to eight weeks of conditioning time in a room at 70°-75°F. Consider this carefully – if you add too much sugar to the bottles, you run the risk of bottle bombs, Chances are high that all you need to do is give your bottles adequate time at the appropriate temperature. For more ideas about carbonating your homebrew, consider this blog post, So, if your homebrew beer is flat can you re-prime? Yes. Should you? Maybe, but not likely.
What PSI is needed to carbonate beer?
Set and Forget – The easiest and most reliable method of force carbonating a keg normally takes around 2 weeks to fully carbonate. While it takes a while, it guarantees that you’ll hit the exact level of carbonation you require. Typically, you’ll hook up your co2 to the keg, set the regulator at serving pressure, between 8–12 psi, and let it slowly carbonate over the course of 2 weeks or so.
How do you force carbonate beer at home?
24 Hour Carbonation – The 24-hour carb is probably the most common practice to carbonate a keg and my preferred method. Your carbonation will continue to improve in the coming days at serving pressure but it’s a quicker way to enjoy your beer with a better carb than the quick carb method.
Place your keg in your kegerator, connect to CO2, and turn the regulator 30-35 PSI.Let your keg sit for 24 hours.Reduce to serving pressure (10-12 PSI). You can purge extra CO2 and serve right away or let it sit for 2-3 days to fully carb.
The extra CO2 will naturally absorb into the beer over the course of the next few days if you let it sit at serving pressure. This would be an option if you’re concerned about purging hop aroma along with extra CO2. You can also be a sport and just dispense at 30 PSI for a few pours.
Does CO2 make beer taste better?
CO2 is an acid, which adds a bit of bite to the beer. Not only does it give the beer’s flavor a nice dash of tartness, it provides a lighter texture than a flat liquid—even dryness—depending on the amount.
Does CO2 keep beer fresh?
2. Using a Kegerator with CO2 – Unlike the manual pump above, a kegerator using CO2 to dispense your beer will keep it fresher for much longer. This is because the keg remains pressurized, but avoids oxidation. In this instance, your beer can remain fresh for months, but the overall time really depends on the beer itself.
If your beer is pasteurized, then it will likely last for at least three months, maybe even six if you store it at the correct temperatures. If it is not pasteurized, then it won’t last as long even if you store it at recommended temperatures. For non-pasteurized beer, you’re looking at maybe two months, give or take.
At this point, you may be asking yourself, “how do I know if it’s pasteurized or not?” This is where you would need to either contact the distributor/brewery or do some research online. If you can’t figure it out, just assume it’s non-pasteurized and treat it accordingly.
Does beer need to be cold to carbonate?
FORCE CARBONATION – Most carbonation in kegs is done using pressurized CO2 from a gas cylinder, a process called force carbonation. The fastest results can be achieved when the beer in the keg is at a cold temperature. This will let the CO2 diffuse into the beer more efficiently and at a faster rate.
How do Germans carbonate their beer?
Follow @BeerSmith Krausening is a traditional German method for carbonating beers without using sugars or other adjuncts. Instead actively fermenting malt wort is added to the fermented beer to provide the malted sugars needed for carbonation.
How long should I let my beer carbonate?
Recently while researching home brewing, I read a lot of forum posts. A question that people ask a lot is how long it takes for beer to carbonate in the bottle. I did some reading and found out the answer to this question. How Long Does it Take for Beer to Carbonate in a Bottle? After you have bottled your beer it generally takes 2-3 weeks for the carbonation process to be completed.
This can vary depending on which type of beer you are making but is a good rule of thumb. Make sure you research bottle carbonation times depending on which beer you are brewing. Continue reading as I dive into how to find out how long to carbonate your beer, and what exactly happens in the bottle as it carbonates.

Does CO2 make beer bitter?
Have you ever wondered how commercial brewers are able to achieve consistent levels of bitterness in their beers time and time again? Well, commercial brewers have been using CO2 hop extract to add a level a bitterness to their beers for decades. If you’ve never seen it before, CO2 hop extract is made up of the lupulin and oils from the hop which are separated from the whole cone in the lab. Source: Imbibe Magazine But what does this mean for the average homebrewer and why should you bother with it? Well, CO2 extract gives you a cleaner bitterness and hop aroma as well as enhanced foam stability, not to mention the fact that it reduces the amount of vegetative matter in your kettle.
You treat it just like leaf or pellet hops added during the boil. This means that you add CO2 extract at the start of the boil to achieve bitterness and then towards the end of the boil you add hops for aroma. Ultimately, this results in less trub in your kettle and an easier brew day! I remember looking at the ingredients on the side of a can of Cloudwater beer a while ago and noticed that they listed their bittering hops as Pilgrim CO2 Alpha Extract,
Being a fan of their beers, this piqued my interest and I was keen to learn more. Lately I’ve been experimenting with CO2 hop extract to achieve bitterness in my beers and have been surprised with the results. In fact, I’ve used CO2 hop extract for everything from Saisons to Pale Ales – you just need to adjust to achieve varying levels of bitterness. Northern Brewer in the US sells Hop Shots in a handy syringe that contains pre-measured CO2 extract for you. However, if you are looking for larger amounts, you could even buy an entire can and split it accordingly.
How do you know if CO2 is too high?
Summary – Mild hypercapnia can be hard to spot. Having too much carbon dioxide in the body can cause nonspecific symptoms like headache, fatigue, and muscle twitches. Often, it clears up quickly on its own. With severe hypercapnia, though, the body can’t restore CO2 balance, and the symptoms are more serious.
Does more CO2 mean more fermentation?
The higher the rate of CO2 production over time, the more energy is created due to fermentation.
How much sugar to carbonate beer?
Corn Sugar – Priming Sugar for Beer Bottling Corn sugar, a.k.a. dextrose or priming sugar (all terms are interchangeable) is the classic sugar used in priming beer and gives consistent carbonation without greatly affecting flavor. Use it at a rate of 1 oz.
Per gallon of beer (or 5 oz. per 5 gallon batch, about 3/4 cup) to prime beer for bottling. It can also be used to add fermentables to beer, wine, cider, or any of your favorite imbibements. Corn sugar tends to lighten body and dry out beers, so it can be used to up alcohol content in lighter-colored beer styles such as cream ales, pale ales and IPAs without adding to body or mouthfeel.

How long does CO2 last homebrew?
How many kegs can be dispensed from a CO2 tank? – A will last between 6-8 half barrels or full kegs before it needs to be filled. A will dispense 10-13 full kegs per fill. This number can be higher or lower based on how often you’re using your kegerator, the level of carbonation, and if your system is properly balanced.
How much CO2 is in a bottle of Coke?
Average liter of Coke contains 6 g of CO2. Bulk 2 liter bottle of Coke 79 cents. That’s all our data.6 grams of CO2 per liter x 2 liters per bottle / 1000 g per kg / 978 kg per ton = 0.000012 tons of CO2 per bottle.
How many pounds of CO2 does it take to carbonate 5 gallons of beer?
There are a few different variables that will influence the answer to this question: size of the keg(s), size of the CO2 tank, pressure in the CO2 tank. Generally speaking, it takes about 1lb of CO2 to dispense a full 1/2 barrel keg (1 barrel = 31 US gallons / 1/2 barrel = 15.5 gallons).
|Keg Size / Style||20oz Cylinder||1.5 lb Cylinder||2.5 lb Cylinder||5 lb Cylinder||10 lb Cylinder||15 lb Cylinder||20 lb Cylinder|
|Corny Keg / Home Brew (5.00 Gallon)||2-3||2-3||7-11||15-22||31-44||46-66||62-87|
|Sixth Barrel (5.23 Gallon)||1-3||2-3||6-11||14-21||29-42||44-63||59-83|
|Quarter Barrel (7.75 Gallon)||1-2||2-3||5-7||10-14||20-28||30-42||40-56|

How much CO2 is used in carbonated drinks?
3.9.4 How is carbonation measured? – Carbonation is measured as either ‘volumes’ or grams per litre. One volume means 1 L of CO 2 in 1 L of drink. This is equivalent to 1.96 g/L (normally quoted as 2 g/L). A typical carbonated soft drink contains approximately 3–4 volumes (6–8 g/L) CO 2,
Carbonation is usually determined in soft drinks by measuring the pressure in the container at a known temperature. The pressure inside a container (can or bottle) is dependent upon the level of dissolved CO 2 and the temperature. Water at 0 o C will dissolve approximately 3.6 g/L CO 2, At higher concentrations or higher temperatures elevated pressure is required to retain the CO 2 in solution.
The standard instrument used by the soft drinks industry for measurement of carbonation is a Zahm CO 2 tester. This consists of a strong hollow ‘needle’ and rubber seal connected to a pressure gauge. The needle is used to pierce the bottle cap or can base.
- The bottle or can is shaken vigorously to maximize the pressure and the maximum achieved pressure is recorded.
- The temperature of the drink is measured.
- The presence of dissolved air/nitrogen and air/nitrogen in the headspace causes significant inaccuracy by increasing the measured pressure, but a correction can be made.
The evolved gas is passed into a burette full of sodium hydroxide solution. This dissolves the CO 2 and permits the volume of dissolved air/nitrogen to be measured. A correction can then be applied to the measured pressure. This known as a Zahm-Nagel tester and was developed by the Zahm & Nagel Company Inc.
- Of New York.
- The CO 2 content is read from a chart of temperature against pressure.
- Some companies use a ‘snift’ method.
- The pressure is initially released (snifted) to flush air out of the headspace.
- The pack is then shaken and the maximum pressure is noted.
- Note that the standard chart was derived using CO 2 dissolved in water and the presence of dissolved solids and pH will affect the result slightly.
However, the accuracy is sufficient for routine control purposes. Colourimetric methods for measurement of CO 2 are available but are not generally used by the soft drinks industry as they are prone to interference in strongly coloured soft drinks and the pressure measuring method is very simple.
How much CO2 is produced making beer?
How Much CO2 Is Produced During Fermentation? So, the other day I was wondering if the CO2 coming out of my fermenter could be used in two ways. Currently I use a spunding valve (adjustable pressure relief valve) on the gas post of my Fermzilla (a pressurisable plastic fermetation vessel with standard keg fittings on top for gas and liquid connections).
- By setting this at what I would usually set my regulator at to force carbonate the beer after it finishes fermenting I keep the beer at that pressure during fermentation using the CO2 produced.
- This means that when primary fermentation is complete the beer is already carbonated and just needs to be chilled! However there is still a bunch of CO2 that blows out of the spunding valve while the fermentation is active and I thought.
“I wonder if there is enough there to flush out all my kegs etc too?” Well, I found the maths online and turn out that YES, there absolutely is! I’ve copied and pasted the maths from an article below that I found by Dennis from the blog but basically the outcome is.
A standard 20L brew produces between 400 and 600L of CO2!!! So now on the blow off side of my spunding valve I attach a line with a gas disconnect on it and use that to push sanitiser through my kegs, lines, taps etc and leave them full of CO2 during the first few days of fermentation. This means they are ready for kegging the brew when the brew is ready with no cost of extra gas to me plus a little bit of help to reduce the carbon footprint of my brewing.
The Maths – Taken From Life Fermented “The results of my calculations are presented here, in both English and metric units. Below I give a bit more detail on the actual calculations. If you look at the plots, you’ll notice that not only is the volume of gas large (left axis), the weight of the gas (right axis) is also quite appreciable.
Yes, your fermentor looses weight over the course of the brew! In fact, some people have proposed monitoring the attenuation of a batch of beer in real time by monitoring the weight of the fermentor. I always assumed you would need an extremely precise scale, but it turns out the difference is so large, you actually wouldn’t.
CO 2 production for various specific gravities and apparent attenuations. CO 2 production for various specific gravities and apparent attenuations. For anyone interested in the math behind the plots, read on. The first thing I did was to convert specific gravity (SG in 1.xxx format) to degrees Plato ( ° P) with the equation This is a third order polynomial fit derived from the American Society of Brewing Chemists gravity to Plato tables, given on, This is a convenient unit to work in because every 1 ° P is 1% by weight sugar, so a 1.060 SG wort would be 14.741 ° P, or 14.741% sugar by weight.
- To find the mass of sugar in each wort, I then found the weight of a 5 gal/ 18.9 L batch by multiplying this volume by its density (if working in metric, this amounts to simply multiplying by the specific gravity since water is 1 kg/L).
- Then, its a simple matter of multiplying by the sugar weight percent.
The example 1.060 wort contains (44.23 lb wort)*(0.14741)= 6.52 lb or 2.96 kg sugar. Note that I actually did all of my calculations in metric, then converted to English because the units work out so nicely. Next, we must find how much sugar is actually consumed.
For this, remember that the “attenuation” used most often is “apparent attenuation” as measured by a hydrometer. Hydrometers actually measure the density of the solution, so when alcohol is created (its density is lower than water), the hydrometer is tricked into thinking more of the sugar has been consumed than really was.
Actual attenuation can by found by multiplying the apparent attenuation by 0.814, as given in Greg Noonan’s New Brewing Lager Beer, So the actual amount of sugar consumed in a 1.060 75% apparent attenuation beer is (6.52 lb)(0.75*0.814)= 3.98 lb or 1.81 kg.
Now we must bring in some very basic chemistry. Lets assume this sugar is all (or could become) glucose. A single mole (in units of mol) of glucose weighs 180.156 g or 6.35 oz. A mole is simply a way to keep track of how many molecules of something there is so you can predict chemical reactions. Basically, there are a different number of molecules of acid in vinegar in a gram than the number of baking soda molecules in a gram, but reactions happen to molecules.
So to have a complete reaction, you need to add the same number of molecules of acid in vinegar and baking soda, not the same number of grams of each. The upshot is we have (1.81 kg)/(0.180156 kg/mol)=10.02 mol glucose consumed in this example wort. For every 1 mol glucose consumed, 2 mol of ethanol and 2 mol of CO 2 are produced., where P is pressure (1 atm or atmospheres), V is volume (liters or L), n is the number of moles of gas (1 mol), R is the ideal gas constant (0.0821 (atm*L)/(mol*K)), and T is the temperature (273 Kelvin or K). Solving for volume and plugging in the numbers, we get Thus every mol of gas occupies 22.41 L or 0.791 cubic feet. This would be (20.04 mol)*(22.41 L/mol)=449.1 L or 15.86 ft 3 of CO 2 produced for our example beer. Put another way, from 5 gallons of 1.060 SG wort, you could fill the glass carboy its in almost 24 times with the CO 2 ! In the most extreme case shown on the graph (1.110 wort, 85% attenuation), this more than doubles.
How much carbonation to put in beer?
More Homebrewing – Essentials Equipment » Basics: All About Grain » Basics: All About Yeast » Whether it’s the crisp, sharp carbonation of a Pilsner or the soft, creamy bubbles in a dry stout, carbonation is a defining texture of any beer style. Carbonation occurs naturally in beer since yeast produce carbon dioxide along with alcohol when they eat sugar.
- 0.5 ounces per gallon for low carbonation (dry stout, English ale)
- 0.9 ounces per gallon for medium carbonation (American ales, porter)
- 1.5 ounces per gallon for high carbonation (German weissbier, Belgian blond)
So if you are going to be bottling our American Pale Ale from last week, using 4.5 ounces of corn sugar for 5 gallons would give an medium level of carbonation. Before you bottle, it’s important to be sure that fermentation is complete, If it’s not, then it’s possible to get too much carbonation in the bottles.
In the worst case scenario, the pressure will be too much for the bottle and it can explode. For most beer under 6% ABV, fermentation will be complete after 2 weeks. In order to test for certain that the fermentation has completed, you will need to check the final gravity (or FG) of the beer a couple days before you bottle.
To do this, sanitize your auto-siphon racking cane and remove enough beer to fill your hydrometer jar about 80% (usually about 3/4 cup). Place the hydrometer in the jar and make a note of the level it’s floating at using the scale on the side. This measurement is the FG.
