First, go to your living room. Trust me.... Flip over your easy chair and shake it all around. Trust me... Flip over your couch. Don't eat the crusty old cheetos that fall out. Trust me, I am not insane. Gather up the loose change. Unlatch the lid, the keg pressure will keep the lid closed. The wedge a penny under each foot of the lid latch, between ...

Even if you turn the CO2 down, there may still be pressure in the headspace of the keg. Flip the regulator off on the CO2 and pull on the pressure release valve on top of the keg. A lot of hissing will ensue as the CO2 races out. You might as well let it depressurize completely as CO2 is cheap. On a side note, don't breathe directly from this stream of ...

I am a very big fan of pressurized fermentation. The benefits I see, in rough order of the value I place on them: 1) Pressurized ferments streamline my process tremendously. This is the big one. Once my wort is chilled, I transfer to a regular corny keg (just under 5 gallons). I keep the fermentation at 5 psi until it starts slowing down, and then I cap to ...

At beer pressures, a keg cannot explode. It's designed to take much more pressure - rated to around 120-130 psi. Even at failure, the seals will fail rather than the chamber itself. Failing at standard beer pressures will be as a leak (pinhole or crack). Which isn't to say they can't explode. It's a sealed pressurized vessel - so it could explode or ...

The inward pressure is caused by the temperature of the air in the carboy being colder than the air outside and/or increases in atmospheric pressure - both will cause the pressure inside the carboy to be less than the pressure outside. This doesn't indicate that there is anything wrong with your brew.

As Denny mentioned, head formation is primarily related to protein though dissolved carbonation level will also have something to do with it. If you're adding a fixed amount of priming sugar to a single pressure vessel, as you dispense beer, the increased amount of headspace will allow some of the CO₂ to leave the beer, making it flatter. You do not want to ...

Foam formation is related to the protein content of the beer and fermentation specifics. You can increase the protein content by steeping some non diastatic malt, like crystal, as part of your brewing liquor. Once you have the protein in your beer, increased hopping increases foam as the polyphenols in the hops bind the proteins in the beer. For the ...

You definitely just need to wait longer. I always wait at least two weeks, more for higher gravity beers. Waiting will not only improve the quality of the head and carbonation level, but almost everything else about the beer will get better if you give it more time. A side note on your step 6, it's best to keep splashing to a minimum when racking after ...

Carbonating the beer from priming sugar takes at least a week, often closer to 2 to be ready. The problem here is that you were sampling a too early: After another couple of days I was tapping off nice pints of dark ale under reasonable pressure (at least I thought it was reasonable pressure - it might not have been) but with no head. I'd only tap a ...

I've done just this for my last 30 batches or so. It's lovely, and I see no reason to go back. I fill the corny to the weld line, bubble some oxygen up through the liquid diptube, and then connect my spunding valve to the gas connect. The spunding valve is just a pressure gauge and an adjustable pressure relief valve attached to a 1/4" stainless tee. To ...

It sounds like what you're doing is correct. (And I guess you've tried turning it all the way to the right - clockwise?) The relief valve can be quite sensitive on some regulators, causing it to fire a little prematurely, so it might have been that, but for the fact that you say the dial jumps to 60 psi. I would double check that the relief lock isn't ...

Given that these are not designed to take pressure, I'd say the maximum safe pressure is zero. Any more than that, and you're taking chances. If that's a chance you're willing to take, then the best way to know the maximum pressure is to get several of these and pressurize to breaking point. The maximum safe pressure is then half of this breaking pressure. ...

I found a study on the effects of brewing under pressure. The general conclusion was that increased pressure reduced the formation of esters and fusel alcohol. This was caused at least in part by a reduction in the amount of yeast growth as the pressure went up. Judging by the active vs total biomass charts, it did not have any noticeable effect on ...

The problem may not be too much pressure in the keg as much as serving lines that are too short. You want the net pressure at the tap to be pretty close to zero. To do that you need to figure in the resistance of the beer lines. Generally it's 22-3 psi/ft. So, if the beer is set at 12 psi. you need 4-6 feet of line to drop the pressure at the tap. Once ...

According to this cidermaker, "regular" beer bottles can hold up to 3 atm (45 psi), and "champagne" bottles can hold up to 6 atm (90 psi). Champagne-style bottles with the large dimple in the bottom are the strongest. That bottom will withstand more pressure before failure than a flat bottom. I bet a standard crown cap would fail before the bottle--you'd ...

Actually, yes. I've read that a longneck industry standard bottle is only rated to about 4 volumes of CO2 - so more highly carbonated beer styles, like weizens, lambics, and certain Belgians, need heavier glass bottles. The last thing a brewery wants is to release a batch of bottle bombs, so the ratings typically have a generous safety factor applied, but ...

If you're referring to this bag-in-box, then there's nothing wrong with it. You basically store flat beer in a box (which is very similar to how soda fountains work), then carbonate it as you serve. You still, however, have to have a CO2 tank where you're planning to serve it, which is still heavy. Your use and shelf-life would be similar to a keg. If ...

You have multiple effects at work here: For one, the carbonation is about absorbing CO2 into the beer. This process lowers the CO2 pressure in the keg. The second point is, that while cooling the beer and the tank, you make the beer able to absorb more CO2, while also reducing the volume of the gas - both in the keg and in the tank. That will lead to a ...

Pressure matters. Most commercial breweries deal with significant hydrostatic pressure as a result of their large conical fermentors, though this effect is negligible at the homebrew scale. Still, many people (myself included) ferment under pressure. The dominant effect seems to be a slight reduction of esters, and as I understand it this is linked to ...

The link to the tubing you posted says the tubing rating is 250psi, and a barb with a clamp would surely tolerate at least 60psi, but I don't think figuring out the maximum pressure the system can safely handle is the way to go. Instead, ensure that your adjustable valve has a maximum pressure so that it that opens when the pressure goes above a threshold ...

You are not likely to have much success trying to force carb in a pressure barrel as they will generally vent before reaching a high enough pressure in order to protect the pressure barrel. They are not designed to hold pressure to the degree kegs are. After 4 weeks, unless the pressure barrel was stored too cool, you are likely to have all the carbonation ...

I've not used this type of equipment, but if you're sure everything is sealed then you should still be able to add more priming sugar and re-carbonate the brew. 4 weeks is a little on the long side, so the yeast may not be as viable as they were, but there will still be sufficient yeast in the beer to carbonate, but it may take a while - a couple of weeks. ...

I'll answer your questions out of order. To get different CO2 pressures, you need separate regulators. You can do it in two ways: I use a dual primary, like this one from Micro-Matic. Your other option is to have one or more secondary regulators after your manifold or instead of a manifold. For #1, in my opinion the best way is to just set it and ...

swasheck have you solved the problem yet? Is the regulator used? I wonder if something has traveled back, up the gas line and into the regulator at some point (used regulator). I'm trying to tell from your picture if your's has a little screw on the front in the middle or a giant chrome "nut" that would take a very large wrench. I use different types of gas ...

I can't say for certain what you're looking for without seeing a picture of your regulator, but there should be some sort of knob or screw on your regulator that you'll need to turn. When you turn that, it should open up the flow from the regulator to the tank, and you'll see the pressure on the second gauge go up. Editing some of the info from my comments ...
