The closest "solution" I've gleaned so far was from http://www.byo.com/stories/wizard/article/section/121-mr-wizard/147-are-welding-oxygen-canisters-safe-for-homebrewing-aeration - which assumes 100% absorption and claims roughly .112 liters is sufficient to reach 8ppm. I buy the math, but I'm not buying the 100% absorption, without an actual test using a Dissolved Oxygen meter, as it is well known that absorption decreases with increased SG - which to me means absorption is never 100%. So I'm curious if anyone out there has ever correlated the volume of pure oxygen injected into wort at pitching temperature and known OG with the resulting dissolved oxygen content. I'd do this myself but I'd rather put the ~$160 price of the least expensive DO meter I've found into continuing my brewery upgrade to an all-stainless steel operation. Cheers!

An hour to 90 minutes is probably best. Do this before pitching the wort. Brad Hi,

I bought a small aquarium pump just last week with an air stone and used it for the first time yesterday. Do you know how long it needs to run for in order to achieve ~8ppm using air (not O2)? Mine says it runs at 1.3L/min. Hi Brad and thanks for the article. I bought a small aquarium pump just last week with an air stone and used it for the first time yesterday.

You should be able to tell if it is fermenting - the bubbler on the airlock should be bubbling away if you have it properly sealed. Brad Hi,

I use a pump to tranfer the wort from the boil pot through a counter flow chiller. This gives me a 5" head of bubble foam. I get very good results for next to nothing. I have done all of the other stuff and will stick with this for another 20 years, God willing. bill tgm For aeration I use A 12″ to 14″ section of 1/2″ copper tubing with several tiny holes drilled in it, about 5″ to 7″ from the discharg end.

One trick I've used is to drop my immersion chiller into the wort for the last 10 minutes of the boil. That sterilizes the chiller. Then when the boil is over I crank up the water and cool the wort. When the wort is cool enough, I raise and lower the chiller in the wort, which does a good job of aerating it because it gets a lot of surface area exposed to the air. Good post.

Most of them carry sterile air filters that usually cost from $5-10. I would recommend any of the popular online beer stores. Most of them carry sterile air filters that usually cost from $5-10.

The problem I had was I bought two dud tanks. The first was empty and the second only lasted for one batch. I did not know this until I tried to oxygenate my next batch and ran short of O2. I would like to buy an air pump for a backup so this never happens again. Where do I get the air filter that was mentioned above? I use the O2 system with an aireation stone I purchased on-line.

An easy and cheap way to really improve your beer. The small oxygen tanks can be bought relatively cheap from your local hardware store to attach to the stone. Great article.
