So if you increase your LPM rate your time goes up? Doesn't make sense to me.

Hello :) I love your videos learned a lot, thank you. I have a question: I can't acquire air cylinder, can I use aquarium air pump instead? Maybe with a hepa filter? Thanks again.

Thank you for your very nice note. I continue to learn a lot too! I have seen where a lot of folks use aquarium pumps. I believe that the important thing is to run it long enough (5 minutes seems to be in the back of my head, maybe I read that somewhere). The other thing is that I believe that the output pressure is lower than a pressurized bottle, so most use a 2 micron stone (O2 systems use .5 micron or 2 micron. The .5 gives a smaller bubble but could be harder to care for due to the ultra fine hole size). I personally use a 2 micron stone and have never had issues. The filter makes sense, I am not sure how that would be incorporated. Here is a nice short link from Greg Doss at WyEast discussing different techniques (they have a good chart on their website too): kzitem.info/news/bejne/mGud1pmen5FneqA Thanks again for watching, all the best to you.

Very interesting video, I have purchased the oxygenating setup you describe, I am not a math expert but it seems the might be an error in the equation,scince all the terms are multiplied together it looks that increasing the flow rate of oxygen you also increase the time required to oxygenate your wort , am I misunderstanding some thing?I am reluctant to try this procedure till it is clarified.,also does the flow rate have to be adjusted so that all the oxygen gets absorbed or can some of the oxygen bubbles reach the surface Thanks Tim Davy UK

Thanks for watching and I think you are correct (someone else pointed this out to me below too). Look in the description and I fixed it and I think I have it right. I got curious and looked around some more this morning and found this link too: www.homebrewersassociation.org/forum/index.php?topic=32266.0 It is pretty simple and seems to correlate with others. In all my reading it seems that 1L for about 60 seconds gets you close. I am running about 90 seconds these days. Also, you see .5 micron stones and 2 micron stones. Certainly there would be a difference. The other thing that I will mention is that by controlling this process you'll be amazed at how long the oxygen bottle lasts. Hopefully this helps. All the best -DT

Hi You have great videos on Your chanel. I have two question: 1.Do You aeration worth before pitching yeast or after, or it doesn't matter when aeration its made? 2.Do You make aeration on every yeast, I ask that because I read that some yeast does not need oxigen even that its not good for yeast. Thank You and Best regards from Croatia

Thank you for your kind note, it made my day. I have always been interested in Croatia, some day I would like to visit there. I aerate with the oxygen before I pitch. I don' t know if that makes a difference or not. The big breweries tend to aerate as they transfer to the fermenter. The yeasts that I use the most are Imperial Juice, White Labs San Diego Super, WyEast 1056, and Fermentis 34/70. I use O2 with all of these. I also now use slightly less flow rate and run it a little longer, 2 minutes. I did this adjustment to make sure as much O2 is absorbed and not simply bubble up. Also, by using the flow meter I can be pretty precise and measure how long my little O2 bottle lasts. So far I have done 25 batches with the single bottle. I can tell that it is almost out so I'll pick up another one soon. Beers on tap right now: American Stout, West Coast IPA, Hazy IPA, Czech Style Pilsner, Northwest Amber. Thanks again for you kind note and interest. -DT

So if i have 60litres converted to gallons= 15.85 gallons and i wanted roughly 8ppm it would take 48.5 seconds at a flow rate of .5(lpm) ? Am i on the right track with the calculations ?

Thanks for watching, this has been an extremely interesting project. You have it right for the 8 PPM density target. I am quick to recognize that our instrumentation and setup are far from "scientific" so I would say you could be comfortable just rounding that up to a minute. As an extra little data point, I am still using the same O2 bottle after 18 batches of .5 LPM for 1.5 minutes. Using this approach really extends the life of that bottle. Without it, my assumption is that folks overdue it (which won't cause issues, but wastes your O2). This is now absolutely part of my every batch routine. Be sure to sanitize your stone thoroughly, I use boiling water and a StarSan soak. Thanks for watching and your comment. -DT

thanks for watching. This is the perfect question to ask and one I often thought about myself. I have been logging the use of my O2 cylinder (just putting a tick mark on it with each use). With my flow rate and duration, I am up to 12 uses so far. I was pleasantly surprised by that because at about ~$10 for the tank it comes out to under a $1 per batch. Once I use the last of it I will update this video with that data. Thanks again for watching and your comment. -DT

@@Trevor.Morrice In my opinion, the little disposable ones you buy at Lowes seem to do a good job. Plus, with the life they have, it seems hard to beat. I think the small additional investment into a flow meter is money well spent (only about ~$12 on Amazon, there are many to choose from). There are all sorts of comments regarding the DO (dissolved oxygen) in the wort and how it quickly dissipates. I don't have any equipment to monitor that. To me it is one of those things you might not need at all, but I figure do all of the small things and you'll get a better product no matter what. I now use O2 and yeast nutrients (and always a 2L starter) and my fermentations go gangbuster, so something seems to be working. I hope this helps. -DT

Thanks for watching and your comment. First off, I am extremely interested in your measured results, in particular how quickly the oxygen dissipates (many say this happens rapidly). Please post your findings here through the comments and I will see them in my email. As for the website, ugh, I should have book marked it because it was tough to find. I went through some bulletin boards like this one: www.homebrewersassociation.org/forum/index.php?topic=32266.0 before I found the equation. I'll look for it again and if I find it, I'll post it here. The time/volume lined up with directions from Northern Brewer and so one with their oxygenation "kits" (stone, wand, etc). One piece of anecdotal data is that once I have started following my own "advise", my fermentation results have been excellent. Thanks again for watching and your interest. -DT

@@homebrewingtips6029 I did an experiment using the formula and used a borrow DO meter and my club and I are trying to write some things up as an education for the club. There is some variance in the results so we are gathering ideas for next steps and experiments. The source of the equation would be very helpful. I used the equation a few weeks ago for two 6 gallon fermenters (one using Imperial A38 and the other using Bootleg Biology NEEPAH yeasts), where I calculated two 12ppm diesels for each spread ~2hrs a part. There by giving each fermenter a total of 25ppm (higher dose rate recommended by Imperial for East Coast Conan type strains). Both fermenters took off better than any other time I have used these yeasts.
