    Shrinking volume of CO2 when cold-crashing - Physics question

    Hi there, I've been brewing an ale last week and next step is to cold-crash. I tried collecting some CO2 in a keg (mostly to flush the keg of O2) and rubber glove to compensate for the suck-back when cold-crashing. But it got me worried it might create such a vacuüm, it actually can bend/pop-in...

    Bottling CO² Vol limits theory

    The reboot is never as good as the original. And I know this has been asked so many times. I'm here for a discussion about the following. I kind of wish this subject had previously received a definitive answer to the question. (I think it's important to say I'm in the UK and have access to...

    CO2 Pressure Won’t Stop Increasing

    Hey folks, Been kegging with the same system for years and something weird just started happening. When I swap CO2 tanks, I always do the following: 1. Turn all valves off and turn pressure as low as possible. 2. Replace tank 3. Open valve in tank At this point, the new odd behavior begins...

    Pressurized Fermentation Resource Post

    I recently made a "resource post" for HomeBrewFinds on fermentation under pressure. I researched the various sources of info scattered out on the web, and tried to filter them with an engineering mind to glean the key technical aspects and practical applications. I also added my experience...

    Question on F2 in Fermentor

    Hello, I have been homebrewing kombucha for a couple of months now, and I use beer bottles and bottle caps to bottle my kombucha. I used to flavor each bottle and pour the kombucha into the bottles and do my F2 in the bottles (like you normally do), but I wanted to have nothing else but smooth...

    Pressure relief valve...

    If anyone out there is in the know, would this device qualify as food safe? It would be used to bleed air from lines between kettles and pumps. Thanks in advance...

    Keg pressure after carbonation

    Hi all, I kegged my first beer and it turned out great. I do however have a couple of questions that none of the guides I find online seem to answer; - after the beer has carbonated to satisfactory levels, you drop it to ~10 psi to serve. After pouring a glass, Do you then have to crank it...

    Wort Canning To Save Time

    One of the most common questions I see asked on HomeBrewTalk is, "How can I shorten my brew day?" Brewing is a relaxing and fun activity (otherwise, why would we do it?), but it can require a significant time commitment. The amount of time required depends on your brewing method and recipe. An...

    Keg pressurisation mad thought

    We need to pressurise kegs but do we need co2? The main washer on my kingkeg is dead and I can't get one. I have had a bizarre idea. I have a football bladder and thought I'll cut it up but then thought why not sterilise it and inflate it in the barrel. I could inflate with air and save money on...

    Can you use the Fermentasaurus pressure lid kit parts on the Fermzilla

    Hi there, I know the actual lids are different but does anyone know first hand whether or not you can remove and use the ball lock posts and float from the Fermentasaurus pressure kit lid and use them on the Fermzilla lid. Here in Canada having a hell of a time finding the Fermzilla lid or...

    Kegging Trappists carbonation settings

    I kegged my first beer recently after years of bottling. I typically carb my Belgians to approximately 3.25. I’m curious what settings people are using to carbonate their Belgians in kegs? Also, do you serve at the same pressure? At 40°F my pressure would be at 20psi. Which seems high for...

    Fermentation Under Pressure

    Anybody have any experience (positive or negative) or thoughts with fermenting under pressure? I'm testing three lagers (WLP815, WLP885 and Imperial L28) simply using 5 gallon kegs with modified 35psi (Red) pressure relief valves. I've modified these valves to get ~13psi. I have no results, as...

    I Love Nottingham Yeast

    This yeast has a special place in my heart and I wanted to share my experiences with it. I have a "Flag Ship" beer (NEIPA) that I feel has only become this way because of the yeast. EVERY TIME I use it, I can count on it to get started within hours and finish within 3 days (I let it sit for a...

    Regulator doesn't stop building up pressure

    Hello, I've just run into a problem with my regulator. It's less then 5 month old and maybe used on 2 batches. Even when the regulator is dialed down as far as possible, as soon as I turn on the gas pressure starts building up and it doesn't stop till the security valve lets out pressure...

    Warmer Larger Yeast

    I have the ability to ferment under pressure and wanted to give a lager under pressure a go --- temperature range would be 66-69 F. What yeast would you all recommended? I am kicking myself for not writing it down but I remember there was a certain brand / strand of lager yeast (or lager sorts)...

    Tilt Hydrometer readings.

    I recently acquired a Tilt hydrometer. I have had a few things happen and am wondering if anyone else has experienced them. 1. I measured the OG of a Helles Lager with a refractometer at room temp and it was 1.041. After placing the calibrated Tilt in the fermenter, it was reading 1.037. I did...

    Carbing pressure vs Serving pressure

    I have two CO2 tank systems, one is my utility tank that I use for carbing my kegs, blowing out lines etc while the other is permanently hooked up to the kegerator and set at around 8 psi to push my beer (I have a 4-way manifold that splits the single line-in to the 4 kegs) So what I'm...

    Lets get real about dry hopping

    First off, hey fellow homebrewers. I'm asking this question because I've been pondering it for years. I have been brewing more then 12 years, all grain, love everything about it. Batch per week average. My favorite beers have recently become NE IPAs, no surprise. I had a chance to drink many of...

    Storing kegs without constant c02 pressure

    I've got the following situation. I've got a fridge to cold crash and store my beers before I move them to my kegerator where I can connect them to constant co2 pressure. I've got co2 available at the "cold crash fridge" but I can only keep 1 keg connected at the time. What i'm doing now is...
