Over-carbonation – One of the most common reasons for kegerator beer pouring foamy is that your keg itself might be over-carbonated. If you’re buying commercial kegs, it is not impossible for them to come over-carbonated. This can happen because of different temperature spikes during transportation and storage or a mistake at the brewery.

How do I stop my keg from foaming?
Keg care basics for your bar or restaurant – A foamy or stale keg pour is a bartender’s nightmare – and it’s not great for your customers, either. If you want to avoid bad pours and get more life from your kegs, keep in mind the following tips:
Let the keg settle after moving it – If you move your keg, give it some time to settle down. If you don’t, you’ll probably experience excessive foaming when you tap it. Just like soda, beer is carbonated – and just like soda, it will foam when you shake it. Try to let your keg sit for at least an hour after you move it. Keep it at the right temperature – Because keg beer is unpasteurized, it should stay refrigerated to between 34 and 40 degrees Fahrenheit at all times. Keep it fresh – A keg of beer will typically retain its full flavor from anywhere from 30 to 45 days after tapping, but that window is very much dependent on storage conditions and the type of beer in the keg. For example, hoppy beers and those containing more alcohol will last longer because hops and alcohol inhibit bacteria growth (see “keep it clean” below). Keep it clean – There are two root causes of spoiled beer in your keg. The first – microorganism growth – is unavoidable; about the only way to prevent it is drink the beer in your keg before the little critters do their damage (see “keep it fresh” above). If you have a more sophisticated set up that includes beer lines, it’s imperative to keep them clean with professional beer line cleaning to keep bacteria, yeast, and mold at bay. The other cause of spoilage is oxidation – typically caused by the presence of oxygen leftover by the pumping process. Oxidation will flatten the beer, giving it a sour taste that can make it undrinkable. Again, professional beer line maintenance is your friend here.
Follow these simple tips to get fresher pours for longer from your kegs. Enjoy! Our 10-point beer line cleaning system uses a time-tested combination of solutions and procedures that virtually eliminate microorganism buildup and mineral deposits that can lead to foamy, skunky pours.

Why is too much foam in beer bad?
When your bartender pours your beer, take a closer look – are they letting it foam, or are they trying for the “perfect” foam-free pour? If so, they’re not doing you any favors. When the beer doesn’t foam in the glass, it’s probably foaming in your stomach and causing a nasty case of (you guessed it) bloating,
- As “beer sommelier” Max Bakker explains in this nifty video, people have been pouring beer all wrong.
- Any real beer pro knows you’re supposed to tilt your glass at the start of a good pour.
- But many pourers will keep the glass tilted until the beer runs out.
- No foam, no mess.
- Right? Wrong.
- When you don’t let any foam loose during your pour, the CO2 stays dissolved in the beer itself.
Then, once you drink the beer and proceed to eat something – say, a nacho or a chicken wing – the foam explodes into a barrage of bubbles in your stomach. That’s what causes bloat, To correctly pour your beer, begin with a slight tilt in your glass. Then, once the beer begins to settle at the bottom, return the glass to its upright position and allow the top to foam.
- The CO2 will all release in a bubbly, airy mess that settles with time – outside the walls of your stomach.
- This is the same reason beer is so much better sipped from a glass than a bottle or can.
- Without first being poured, all those bubbles are just waiting to unleash an explosion of foam after you drink it.
Just because it makes you bloat doesn’t mean beer is completely bad for you. No one’s saying it’s a health food, but here are 10 totally legit medical reasons you should drink more beer, View slideshow related stories

How do you burp a keg?
FILLING THE KEG: – Ferment your beer in the normal way. The day before fermentation is completed is the time to clean and sterilise the keg. You can use most of the liquid sterilizers sold in Homebrew shops in the same way that you would sterilise your bottles.
We have found the best way is to 3/4 fill the kegs with water and liquid sterilizer, hold the lid in place and fill with gas (40 PSI or 280 KPA ) allowing the pressure from the gas to seat the lid in place and then clip the lid down. Turn the keg upside down for about 4 hours and let the sterilizer get into the fittings at the top of the keg.
If bacteria is going to grow this is the most likely spot. Then turn the keg upright and leave for another 4 hours to clean the bottom of the keg. Once this is complete release the gas, pour out the sterilizer and rinse with clean water. The transferring of the beer to the keg is as simple as racking directly into the keg via a piece of clear sterilized tubing, cut to length so that it reaches from the tap of the fermenter to the bottom of the keg.
- You will notice that there is a tube in the keg running from the top of the keg to the centre of the bottom.
- This is called the Drip Tube, this is how the beer is drawn from the keg.
- There is also another tube that is quite short in length.
- This is the Co2 inlet, where the Co2 is injected into the beer.
Your keg should be filled to approximately 12-25 mm (1/2 to 1 inch) from the bottom of this tube. Now the keg is full replace the hatch cover and move keg to the fridge. Assuming your gas line was cut to length it should be long enough to reach outside the fridge so you can connect it to the gas bottle.
Turn the gas bottle on and set pressure on regulator to 40 PSI or 280 KPA, hold the lid in place and connect the gas line to the keg. Allow the pressure of the gas to seal the keg and then clip the lid down. What we have to do now is purge the air from the headspace of the keg and replace it with CO2.
This is done to protect the beer from oxidisation. By lifting the pressure release valve the CO2 will flow into the keg and the air will flow out through this valve. This is called burping the keg and is best done in half a dozen short bursts.
How long does a keg need to settle?
A: You tap a keg by using a keg coupler. If there has been excessive agitation during transportation, allow the keg to settle for 1 to 2 hours before tapping. Make sure the beer faucet is in the off position prior to tapping.
Can you overpump a keg?
Tapping – Once you tap a keg, you need to take a few simple steps to make sure that you get a good flow of beer. DO NOT OVERPUMP! If the tap has a pressure release valve, use it to completely bleed the pressure off of the keg (it will build considerable pressure on the trip home).
Can you pump a keg too much?
How to Tap a Keg – Allagash Brewing Company Our guess is that you searched this on your phone and have a keg sitting nearby, waiting to be tapped. First, stick that keg in a bucket of ice. The keg actually pulls beer from its bottom, not the top, so if you just keep the lower third of the keg cold, you’ll enjoy frosty beer until it kicks. STEP 1: Lift the handle of the tap to “disengage” it. STEP 2: Line up the bottom of the tap with the mouth of the keg. STEP 3: Turn the tap clockwise until you feel resistance. No need to crank on it, just make sure it’s snug. STEP 4: Push down on the handle to tap the keg. Pump a couple of times (don’t overpump!) and you’re ready to pour. The hand pump, or “tap”, will have a handle on it. The handle should be able to be pulled away from the coupler body and lifted up. This will “disengage” it.
Place the bottom of the coupler on the spout of the keg (located on top of the keg, sometimes covered by a little plastic cap, which you should remove before placing the coupler on the spout). Make sure the base of the coupler laces into the grooves inside the keg’s spout. Turn it clockwise. No need to crank on it, just stop when it feels nice and tight.
Any more tightening will just compress the rubber pieces inside, making for more wear and tear. TAKE A SECOND: does the coupler look like it’s on right? Is it snugly fitted into the opening and not slanting? If not, unscrew and try again. If it does look right, press down on the handle that we lifted up in the first step.
This will “engage the coupler.” Now just grab the coupler’s dispensing hose, grab a cup, and start pouring! To un-tap your keg once it’s kicked, you’ll first want to lift the handle. To do that, you’ll most likely need to pull the handle outwards before it’ll lift up. Once you lift the handle up, just turn the tap counter-clockwise until it pops right off.
Voila, keg untapped! Have foamy beer? Stop pumping! More often than not, your guests—or you—get excited and want to dispense your beer like Vin Diesel: fast and furious. So you pump the heck out of the keg. If you pump too much, the beer will be overpressurized and foam up, making for a very painful and frothy pouring process.
Another interesting fact: the typical “Party pump” taps that you’re often given when you rent a keg add oxygen to your beer, oxidizing it and changing its flavor (most often for the worse) over time. If you want to keep your keg fresher, longer, look into a CO2 pressurization system and a kegerator. Second reason for foam? The beer is too warm! Cold beer can hold more CO2 than warm beer.
When warmer beer hits a glass, the CO2 can no longer be contained and will leave the beer, causing it to foam up. So how long does it take to chill down a warm keg? It depends on starting temp, ending temp, and method of cooling, but think of it like a thanksgiving turkey: better to start the night before (with cooling rather than thawing) to make sure it’s at the perfect temp for when guests arrive.
Ready for your mind to be blown? Another cause of foamy beer: too little pressure. If nobody has been pumping the keg at all, the CO2 will break out of the beer and separate. You’ll also probably notice that the beer is pouring a little more slowly, so that should help you differentiate between an over-pumped vs, an under-pumped keg.
That’s about it! : How to Tap a Keg – Allagash Brewing Company
Why is my keg slow and foamy?
Your Serving Pressure is Wrong – The ideal serving pressure should be between 10 and 12 psi, though some styles demand lower and some higher. Typically, 12 psi works well. If your serving pressure is too high, it can pump excess co2 into the keg and lead to foaming. Check your regulator and adjust as required.
What should the CO2 pressure be on a keg?
WHAT PRESSURE DO I NEED TO SET THE CO2 REGULATOR AT? – It’s always best to check with your beer wholesaler’s draft technician as to setting the regulator pressure. For a keg refrigerator at 38˚ F, the recommend CO2 pressure is between 12–14 lbs for most domestic beers.
Can you recarbonate a keg?
Method 2: – The other force-carbing method is similar but will carbonate at a faster rate. However, it’s important to note that it involves more effort. First, attach the gas supply to the keg in the same manner as the first method. Once the system is hooked up, turn the gas supply up to 30 PSI.
Then, gently shake the keg to stir up the beer inside. You should immediately hear bubbling within the keg. Agitating the keg increases the contact area between CO2 and beer even further, promoting faster diffusion of CO2 into the beer. Continue to shake the keg for 20-30 minutes then lower the pressure to 20 PSI and allow the keg to carbonate for 2-3 days.
Check the carbonation levels and enjoy!
Will a keg go bad without CO2?
How Long Does A Tapped Keg Last? – The method you choose for dispensing your beer also plays a major role in how long your keg stays fresh. Using a kegerator or draft system that dispenses draft beer using CO2 should not impact your beer’s freshness as long as the keg is stored at the proper temperature and pressure.
- You can follow the guidelines explained above for determining how long your tapped keg will last.
- Using a picnic pump, party pump or keg tap is a completely different situation.
- These introduce oxygen into your keg, which greatly speeds up the process of beer going bad.
- Since a picnic pump uses oxygen instead of carbon dioxide, a tapped keg will only last about 12-24 hours depending on the type of beer and how much oxygen was pumped into it.
The oxygen will cause the beer to go flat and spoil quickly if you don’t finish the keg within that time frame.
Why is my keg too cold foamy?
Incorrect Temperature – If the beer is too warm or too cold, it will be more easily disturbed and pour as foam. In most models, the beer line is not refrigerated so the first pour will usually be a bit warmer and a bit more foam. Most beers should be kept in the low 40 degree Fahrenheit range.
Does more foam mean better beer?
Ask a Beer Pro: Why Is It Important to Have Foam on Beer? Often referred to as the “head,” the half- to one-inch layer of thick foam on top of a beer is the first sign of a well-poured pint. “Aesthetically, foam makes a beer just look more inviting,” head brewer Mike Nika states in an email.
- A beer sans head looks lifeless and makes me anticipate being disappointed by whatever I’ve ordered.” Beyond visual appeal, the head provides a variety of benefits.
- It influences the aromatic experience and adds an enjoyable texture to the brew.
- As drinkers sip from a foamy pint, the beer’s aromas unfold as the bubbles dissipate.
Tight, uniform microbubbles are the sign of high-quality brewing, Nika says. If the foam is too large and sudsy, it might be a sign that the carbonation process was rushed or the beer was under-carbonated. Get the latest in beer, wine, and cocktail culture sent straight to your inbox.
- Greenpoint Beer employs a “low and slow” method of force carbonating beer, wherein carbon dioxide is slowly added to the beer over the course of several days, creating a tight foam that floats atop the beer for longer.
- Beyond production methods, the style of beer also influences the look, texture, and retention of a beer’s foam.
Barley and wheat-based beers produce more natural carbonation during fermentation, while those with corn additives can easily fall flat. Nitro beers stand tall above all others, with especially pronounced heads. “, for example, is carbonated primarily with nitrogen, which when poured properly, results in a wonderfully creamy and cascading foam,” he says.
Unlike in a traditional beer, the nitrogen escapes the beer very quickly and it is prone to tasting flat unless consumed quickly. Being served Guinness without foam is a crime, if you ask me.” If a pour lacks this signature head, are bar-goers within their rights to send back the pint? Nika says yes, it’s fine to query any issues regarding the presentation of a drink, including dirty glassware or substandard foam.
If a bar doesn’t have a craft beer focus, though, he says the safest bet is to simply order a can or bottle to avoid disappointment. : Ask a Beer Pro: Why Is It Important to Have Foam on Beer?
Should I let keg sit after tapping it?
3. Let It Settle Before Tapping – When you get your keg, try to be gentle with it. It doesn’t matter how large or small it may be, it is important that you try to limit how much you shake or roll it around. It’s always wise to let it sit idle for a few hours before tapping it.
- We all know what happens when you shake a can of beer and then immediately open it.
- The same principles apply to a keg, as it does a can of beer.
- Once you get your keg set up in your kegerator, we would recommend letting it sit for at least an hour or two before drinking from it.
- This should be plenty of time to let it settle a bit.
However, depending on how long it took you to get from the distributor to the kegerator, you may need to give it more time to chill a little long to reach the proper temperatures.
What is ideal keg pressure?
The Basics of Keg Pressure – Pressure is an imperative component of all fully-functional draft beer systems. It’s what keeps your beer carbonated and tasting fresh all the way from keg to glass. Having too much or too little pressure will affect the way your beer is dispensed, and you won’t be able to enjoy its full potential.
These keg pressure pointers will help you find that perfect medium. About Head Space As CO2 enters a keg, it displaces your beer at a constant pressure. When you open the tap/faucet, beer flows out of the keg and into your glass due to a push from the CO2. The gas then fills the space where the beer was formerly housed, and that’s the “head space.” The CO2 fills the head space and maintains the pressure inside of the keg at the PSI set on your regulator.
This constant PSI keeps the beer carbonated by preventing CO2 leakage. Keep it Straight Your CO2 tank must be stored upright or it won’t work properly. Storing the tank improperly can also cause expensive damage to your regulator. Find the Magic Number Most ales and lagers produced in the US should be dispensed at 10 – 12 PSI.
- Stout and other nitrogen-reliant keg beers are usually dispensed at 25 – 30 PSI.
- For the specific dispensing pressure for a particular keg, check with your local beer distributor.
- Too Much Pressure Too much pressure will leave you with foamy beer that comes quickly out of the faucet.
- If your beer is over-carbonated, the foam will appear tight with large bubbles.
If you encounter this problem, it’s easy to fix. Adjust your regulator pressure to the proper lower level and draw a few foamy pitchers. You can also use your coupler’s relief valve to bleed out the extra pressure. These measures will force your system to balance itself out again.
- If the pressure is left too high for too long, CO2 will be forced into the beer resulting in permanently over-carbonated and excessively foamy beer.
- Thus, it’s important that you address this problem as soon as the issue is identified.
- Too Little Pressure Too little pressure will also force foam because the CO2 can break free from the beer as it enters your glass.
If the pressure is not raised to the appropriate level, your beer will eventually become flat. When you see foam or bubbles visibly rising in your beer hose, this is a telltale sign of low pressure. If your beer is under-carbonated, the foam will look loose, often described as appearing “soapy” with small bubbles.
To correct low pressure, first check to make sure your CO2 tank isn’t empty and that it’s turned on. This seems like a “duh” suggestion but sometimes it’s the simplest issue that causes the problem. Next, check your regulator to be sure it’s set at the right level. If the tank is functioning and there aren’t any obstructions in your gas line, and your regulator is set to the correct PSI, then most likely your regulator or gauge needs to be replaced.
Unfortunately, regulators do wear out and typically need to be replaced every 4-6 years or so.
Why is my beer soapy?
Soapy flavors in a beer can of course come from leaving soap remnants in the fermenter, but they can also be created by fermentation conditions. If your beer stays in the fermenter for longer than is suggested (we always say 4 weeks max. for initial fermentation), a soapy taste can occur because of the breakdown of fatty acids in the trub.
