    New York O2 Kit -NYC Area

    Got this O2 kit for my high-gravity brews, but have started using it on all my brews. It really smoothes out the fermentation, helps prevent stuck fermentations, and cuts down on the higher alcholols. Happy yeast=better beer. $70 new, I’m selling for $50, and throwing in 2 free bottles of 02...

    Dissolved Oxygen Experiment- Interesting Finds with Beer Transfer Method

    I recently did a hands on review of a Milwaukee MW600 Dissolved Oxygen meter for HomeBrewFinds. Review linked here. As part of trying out the meter, I did a bunch of different experiments looking at dissolved oxygen. One of them that the results surprised me on was method of beer transfer...

    Oxygen danger/helpful?

    Hi! I'm making my first mead (with Lalvin EC 1118) and I have a few questions about the aeration of the must: I read that it was best for the yeast to aerate it at the start of the fermentation to avoid stressing it too much and produce off flavours. My question is: until when is it good and...

    Fermenting Under Pressure

    I first fermented under pressure by casting out as usual, oxygenating the wort, pitching yeast, capping the fermenter (I ferment in kegs), then pressurizing with CO2 and immediately questioned why I wouldn't have done so with O2. I haven't seen this discussed anywhere and most discussions and...

    Mead without an airlock?

    Hi everyone, I started my first batch of Meade yesterday, I have left it in a plastic bucket with a sealed lid but no airlock. Do I need to release the CO2 if so how often and does it matter if oxygen gets into the mixture? Many thanks, Josh

    Adding oxygen to yeast starters?

    Anybody ever add oxygen to their yeast starters? I know it makes a HUGE difference in turning wort into beer. Does it make a difference on a yeast starter with a stir plate? Assuming all best practices for cleaning, sanitizing, etc are followed, will it make a noticeable difference? My plan is...

    Cold crash suck-back volume estimate?

    is there any general guidance for the volume of gas being sucked back when cold crashing? E.g. if I have a 6.5g carboy and 5.5g of beer, and I cold crash from 68F to 35F, what volume of gas should I expect to suck-back? if this is pretty constant and predictable, I'd like to create a large...

    Let's talk about Oxygen.

    So far, I have not oxygenated any of my beers. Seems to work okay. Using US-05 yeast either pitched fresh on new wort, or left in the trub and the next batch poured directly on it. I have even gone so far as to purge the fermenter with C02, thinking it was a good idea because Oxygen is the enemy...

    Harder to get carbonation when using beergun with CO2

    Hi! Everytime I use my Beergun and give each bottle a good spray with CO2 before filling the beer, the carbonation take forever. Sometimes up to 3-4 months. I use the same amount of primer as I always do. The only differense is the lack of oxygen in the bottle. Is that the reason? Does anyone...

    Step feeding must vs oxygen "pollution"

    I’ve got a question I’m hoping can get answered by the wealth of knowledge stored here. I’ve started my first larger batch and I’m afraid I may have made a mistake. My first attempt was a single gallon, well over a year ago, that was about as basic as it gets and tasted harsh. Since that time I...

    Have I ruined my beer!? - secondary fermentation

    I recently started my first batch of beer. I am making a Rose Petal IPA. I recently siphoned into secondary 3 days ago. I steeped some rose petals and put them in a mushlin bag and into the carboy to float. I was worried about the carbonation from the rose petals because they were not sunk to...

    Is my regulator leaking?

    Recently I got an Air Liquide Blueshield Series 45 Oxygen regulator at a garage sale for $10. I decided to retire it for my CO2 system. I had the inlet nipple replaced. I used Teflon tape and pipe dope to seal all the threads and soap test showed no leaks. However I did the following test which...

    Where do You Find Notable Difference with Oxygenation Stones?

    I've been trying out some oxygenation stones (both 0.5 micron + O2 tank, and aquarium pump + 2 micron stone) lately. My standing process is I pass the wort through a strainer as I transfer from kettle to fermentor and let that aerate/splash. I did two trials where I split my wort into 3...

    Copper equipment & Hop oxidation

    I wasn't able to find any explanation in searches so I'm posting a topic. In some discussions related to NEIPA and related intricacies of heavily hopped beer I've seen comments about copper immersion chillers and "wanting to go SS" which leads me to this question: Is it known whether copper...

    Ascorbic Acid Super Oxidizer?

    I've read on a previous thread here that supposedly ascorbic acid by itself can become a super oxidizer instead of an antioxidant. But I've used it by itself and never noticed an issue. And noticed many food items using it as a preservative by itself with no MS. And I know metabisulfate is good...

    Pure O2 oxygenation formula

    I haven't brewed in a while and am revving up for a brew day. One of the things I needed to refresh my memory on was how long I was running my pure 02 tank (through a .5 micron stone) to oxygenate the wort before pitching. I have a medical regulator on the tank and can control the flow down to...

    Oxidation after first pour from tap

    Hey fellow homebrewers, Can you help me solve this oxidation issue I've had for the past year? Issue: My beer in the keg oxidizes after the first pint is poured. The first pint is perfect and has no hint of oxidation. About two days later, heavy oxidation has set in and the beer quickly...

    how long to apply O2 while transferring?

    I have a blichmann oxygen flow regulator that I haven't used yet and I'm wondering what flow and how long to apply o2 while transferring?
