I plan on ussing a bag/balloon filled with CO2 attached to the fermenter when cold crashing. I want to calculate how big this bag needs to be. Assumptions: Fermenter Volume: 30l (23l beer) Room Temp: 20° Celsius Beer Temp before Cold Crash: 20° Celsius Beer Temp after Cold Crash: 3° Celsius How can I calculate the volume CO2 that is sucked into the fermenter? My approach was to look at the Density of CO2 at the different temperatures: 1.815 g/l …

So I am almost done fermenting my first batch of home brew and am about to start kegging it. The only problem is the current hose coming from the regulator is a good bit wider than the nozzle I have on my homebrew keg. Is this something that can be fixed somehow, or should I look to replace one of the nozzels? Does the hose width matter much for delivering the pressure to the keg? EDIT: connector looks like this: …

I'm looking at purchasing a stainless steel carbonation cap. E.g. https://www.homebrewfinds.com/2018/12/hands-on-review-ferroday-stainless-steel-carbonation-cap-for-pet-bottles-draft-line-cleaning-builds.html If you do a Google search for "stainless carbonation cap" you can see them listed at lots of online brewing stores. Most of these online stores list the following uses for the cap: Carbonate Cleaning your beer lines Use it to counter pressure bottle fill PET bottles Numbers 1 and 2 make sense to me. However, number 3 is confusing me. How can you counter pressure fill a bottle …

I have a batch of beer, fermented and then bottled. When I open the bottle, there is a lot of foam and it flows out of the bottle for a while. What could cause this? I assume it's too much CO2 and thus too much priming sugar? (This is a 5 Gallon Batch, mixed with Water/Sugar in a bottling bucket, so no Fizz Drops) Should I leave the bottles alone for another week or two? Could temperature cause it? (Temperatature …

I made a DIY CO2 system for my fish tank. I use fermentation for the CO2. 2 and a half weeks ago I filled a 2ltr soda bottle with water, 2 cups of demerara sugar and a tsp of bakers yeast. This wasnt intended for drinking (no sanitisation first etc) just for producing co2 as cheaply as possible. I came to change my mixture today and rather than just throw away whatever it is i'd fermented I thought i'd try …

I'm making my first pressurized brew using a fermentasaurus . All has been well for the first couple of days, but unfortunately one of my children had a "what does this do?" moment and opened up the spunding valve and let all the pressure out ;) What would be the best way to increase the pressure ? I've tried googling but the only thing I can come up with is "charging" in order to bottle or transfer to a keg. …

Say I have a keg of beer at around room temp. (23C/73.4F). I want 2.2 volumes of CO2 carbonation so using this calculator I figure out I need to add 25.83PSI of pressure - some time later the beer is carbonated. To serve the beer, I decant 5 litres at a time into a mini-keg which I keep in the fridge (3C/37.4F). The same calculator says that starting from scratch, I would only need to add 7.82PSI @ 3C. But …

I have a 5 gallon keg that I have filled with approximately 4 gallons of liquid. The keg has an inlet and outlet fitting for gas carbonation. The inlet fitting is shallow and the outlet fitting goes all the way to the bottom of the tank. My normal carbonation process is done through a pump connected to the keg moving the liquid around and this pump is also connected to the gas cylinder pumping 10psi of CO2. The keg with …

I am very new to home brewing. I have finished making my first batch of DME beer. Although during bottle conditioning I could see enough CO2 bubbles getting generated, upon opening the bottles after about a week, it didn't generate the foamy head. However, if I agitate the bottle, I manage to get some foam. If I refridgerate the bottles after conditioning, the beer becomes completely flat. Am I doing anything wrong? How can I ensure a decent foamy head …

I recently started gathering equipment for home water carbonation and collected my CO2 tank today to find the regulator I purchased does not fit it. I am based in Ireland, here is the regulator I purchased: https://www.schankanlagen-koch.de/AfG-Hauptdruckminderer-CO2-Druckminderer-Hauptdruckregler-HIWI-Euskirchen-3-bar-1499.html And here is the gas tank: As you can see the fittings are completely different, the tank has a female connection while the regulator expects a male. The regulator is for CO2 and the tank is pure CO2 not a mixture or other …

I used this Quickcarb to carbonate my beer, but when bottled (with a BeerGun) I get too much foam in the bottle and almost no beer, after finally filling the bottle I tap it. And when I try my beer it does not have almost gas or sometimes nothing ...... do you have any advice that can help me with this? I would greatly appreciate it :).

If I put some beer in a secondary vessel for medium-term condition (e.g. lagering or dry hopping), do I need to put an airlock on it or can I just close it up with a stopper or put it in a keg and seal it? Presumably the yeast are not really generating any more CO2. (Note: I'm not talking about an actual secondary fermentation with fruit or something, where the yeast will clearly be active.)

Does anyone have a formula for forced carbonation level (dissolved CO2) as a function of beer volume, temperature, CO2 psi, and time? I assume that this function would be logarithmic with respect to time, while psi, temperature, and volume might be scalers. Another input to the function would be the area of the headspace-to-beer junction. Lets assume this is constant and held at the internal cross section of a Cornelius keg. I've looked at several forced carb charts and they …

For the record, I am using some storebought kegs, but figure you guys know more about all of this than I do. EDIT: I checked the internet and the couplers to the keg are of the sanke variety. Here's the deal: I have a two tap kegerator and the aggressive amount of foaming is wrecking my beer drinking experience. I've got the CO2 set to the lowest setting the regulator will allow (4psi) and it's kicking out SO much foam, …

I got an annoyance issue here. I have a Cornelius keg 19lt and 15-16 liter batch of Wit-beer almost ready to go, but poorly timed.Issue is I currently don't have the CO2 regulator or Tank. Reason for this is currently I shouldn't really be dropping money to get it within the near future (2 months) and due to other commitments I can't really be spending time bottling either over the same period. I'd like to just dump the whole lot …

I know there are priming sugar calculators out there to help decide how much sugar one should add but is there any thing as too much priming sugar and if yes what would be the side effect to expect? I have brewed two batches now but they both lacked carbonation and were out right flat. And I was using Northern Brewer's Fizz drops for priming but the complication was I have 16oz bottles and fizz drop were for 12oz bottles, …

I connected my CO2 Cylinder to my Keg and have it currently force-carbonating. However, it will only be needed next week friday. Should I leave the CO2 Cylinder connected for 8 days at 20psi, or should I just disconnect it and leave the Keg in the fridge until next week?

I recently made some cider, but when the day finally came to try it there was no carbonation (evidently due to a slight hole at the top of the pressure barrel). I am planning on transferring the cider into a new barrel but not sure the best way to go about this. Do I need to add more sugar and allow time for secondary fermentation, or can I just inject CO2 and start drinking?. Any advice greatly appreciated.

It seems as though there are two predominant methods of kegging: "saturation over time" and "high pressure and shaking". I have also seen only two references to another method: connecting the Gas In line to the Beverage Out post of a ball or pin lock keg and saturating the beer from the bottom over the course of about two days. It seems like a foolproof compromise between control and speed, but the lack of discussion about the method leads me …

I'm looking to make some carbonated beverages, and I purchases some flip top bottles. I'm also looking into adapting CO2 with a pressure regulator to carbonate the beverages. From what I've seen I can readily find CO2 fittings for a plastic soda bottle for carbonation, but I'm also looking for a fitting so I can carbonate the flip top glass bottles. I know that there is some danger with the glass bottle exploding, but I figured that if I only …
