I believe Henry's Law applies here. If I recall it is something like C=kP. The solubility of a gas in a liquid at a given temperature is directly proportional to the partial pressure of that gas above the liquid. Dissolution, equilibrium, blah blah blah. Blaming it on "missing a chemistry...

So there's CO2 under pressure in the headspace, it makes itself cozy with the beer and vanishes from the headspace, and therefore no more pressure. Witchcraft I say! Witchcraft!

Yeah I still can't wrap my brain around CO2 absorption. Add a few psi and it will be absorbed so the 2 psi you put in there is still in there but somehow the pressure has dropped back to zero. Where did the pressure go? The CO2 you put in there, is in there, but the pressure is not. But for the...

It seems to me that "crashing after kegging" is essentially the same thing as "transferring from ferm vessel to keg then putting keg in kegerator". I have done that and eventually I get the same beer as if I crashed before kegging. But it seemed to take waaaay longer to get clean, clear beer...

This triggered a thought: I could simply add the keg in my existing setup between the ferm vessel and the accumulator. I would have a purged keg ready for filling and any suckback from the airlock would drop into the accumulator, not into the keg. Dang that might work. Achieves both my goals of...

This would work for sure during fermentation. Not sure how well it would work during cold crash, based on my experience pressurizing the fermonster. I have experimented with disconnecting the blowoff from the fermonster and slightly pressurizing it with CO2 before starting cold crash. I tried...

I failed to mention two goals for this project, which I have achieved: (1) Completely hands-off from pitching to kegging. My DIY fermentation chamber monitor will run the entire process, without me touching a button or hose, from pitching to kegging. In "auto" mode it maintains ferm temp and...

The Problem: Cold crashing creates a vacuum in the fermentation vessel. This vacuum creates "suckback" through the airlock or blowoff tube which may introduce one or more undesirable components into the ferm vessel: airlock fluid, O2, or spoilage organisms. I have tried every suckback solution I...

Sorry for the delayed response. Bluetooth is a non-starter. Kegland told me that Bluetooth only works with a bonded kegland device. Pitty. Unfortunately kegland was silent on my ask for help with pulling api data directly from them. I wonder if they read what I was up to and don’t like the...

I am looking for a python scrip that will allow me to get data directly, or nearly directly, from the @KegLand Rapt Pill. My preference would be to use API GET to pull data from rapt.io but as a second option I would be okay using the bluetooth capability of the pill to get data even more...

I have a few Rapt pills so I am familiar with posting data to brewersfriend.com for my brewing sessions. Since I usually brew multiple batches at once, I sometimes run out of pills. I am fermenting small batches in corny kegs and I thought it would be nice to at least know the temp of the...

Not a fan of hazies but when I'm out for drinks or dinner I'll have what is available. Unfortunately a few of my favorite dinner spots have replaced all IPA's with one hazy or another. So I've taken to drinking other styles as necessary. Also not a fan of the "fruit" beers that I am seeing on so...

Picture shows what I am looking for in color. For some reason ritebrew doesn't carry Briess Black Barley but I think I could substitute Bairds roasted barley. I'll put this one on-deck. So many recipes, so little time...

Thanks all for your input. I have decided to try the following grain bill based on the nearly universal observations (1) there's a lot going on with the recipe and (2) roasted barley is where red should be coming from: 6 lbs Briess pale ale malt 2 row 4 lbs Bestmalz Best Red X 4 oz Briess...

OP mentioned glass carboy, which would be unsafe (IMO) to pressurize for a closed transfer. Closed transfer from plastic (or SS) fermenter yes, from glass fermenter no.
