Simple Aeration?
« on: December 28, 2013, 04:46:03 PM »
During my time on this forum I've come across several methods of aeration and some pretty elaborate methods. I once used a stirring rod that hooked up to my drill but have since even gotten away from that since I've started to filter my wort through nylon stockings into a bucket about 9 or 10 months ago. I was wondering if anybody else does the following or has any comments or concerns with my method....

As said above, I filter my wort into a fermenting bucket. Then I slowly dump the wort through a funnel and into a carboy. It appears that I have adequate aeration after this pour. I usually have active fermentation in 6-10 hours.

I will be pumping to fermentor after whirlpool settles. I then let my wort and yeast pitch sit in the refer over night. The next morning I aerate with a mix stir and pitch.

I pour from my kettle into two buckets through a strainer. I carry the two buckets downstairs and pour them into my conical. All that pouring whips up all the air my yeast needs.

After I transfer my cooled wort to conical, I aerate with 100% O2 for 50 seconds using aeration stone/rod (from Williams) hooked to small/cheap 02 welders tank u can get at any hardware store.  I boil the stone and then soak in stars an prior to aeration.

I also just shake it, but love reading all the different processes. Cheers.

Ok... Good... I was starting to think that I was the only brewer without an O2 pump.

I read somewhere once that dumping a couple of gallons of wort into a couple gallons of wort will oxygenate just as much as an air stone will. I have also read that there is some kind of disadvantage to this as well but I don't remember what it was. I just do it so that I don't have to carry 5 gallons of beer down my stairs in one shot and the oxygenating is just sort of a bonus.

Air will get you to 8 ppm. That is fine for most beers. I have started just pumping most ales into the fermenter, and that does fine.

For lagers or high gravity ales I use O2.

I was using O2 for everything, and the ales were too clean, they lacked character from the esters.

Nope, you're not. For beers sub-1.090 OG I've never found any real advantage to using 02. I think above that gravity a minute or two of 02 can be a benefit. A mix stir on a cordless drill is what I use for pretty much everything and I get quick starts and good attenuation.

I pour hard and/or shake the bucket for a few 15-second bursts for most beers. Beers over 1.080 or so get about a second of O2 for every gravity point. But if you don't have oxygen, a second aeration with something like a whisk/mix-stir/slotted spoon after about 12 hours would make up for the lower O2 saturation from air. I did this prior to my O2 setup and never had an issue.

I rack so that the wort fans out on the side of the carboy.  I then follow with 45 secs of shaking.

I use a siphon sprayer at the end of the tubing coming off of the ball valve. It has worked well for me.

Fill the headspace in the carboy with oxygen, put a stopper in it, rest the carboy on the floor, tilt the carboy 45 degrees, and twist it back and forth - shaking the beejeebers outta the wort.  You can supersaturate the wort with oxygen this way.

Using this method with ambient air (21% oxygen) is highly effective too.
