It's simple. Watch the bubbles. If most of them are reaching the top, you're using too much.

You guys sound like you're in this pretty deep, but I'm going to go ahead and cite Palmer when he states that using pure oxygen vs stirring/pouring back and forth, while the differences are nearly impossible to discern immediately, the pure oxygen brews routinely score lower than the stirred-in air approach.

I don't think "unfiltered" air should be of any great concern unless you're brewing in a lumber yard or a factory or something.

That being said, I realize it can be fun to make things a little more complicated...

If you don't mind, could you link to where Palmer said that the pure oxygen brews score lower than the stirred ones? I couldn't find it in How To Brew. I either overlooked it or perhaps it was somewhere else? Thanks.

Hey guys this might sound crazy but here is a very cool article about an alternate method to aeration. Give it a look.

Sorry just never saw it. Thanks for the heads up.

There's nothing complicated about aerating with O2 at all. In fact, I think it's much easier than pouring back and forth or shaking a heavy carboy/bucket.

I was talking to a master brewer in Albuquerque, NM about aeration of wort, and I mentioned that I used an aquarium pump and a sintered stone. He told me that I should consider purchasing an oxygen tank to aerate the wort, because it is relatively inexpensive and does a better job of increasing the partial pressure of oxygen in the wort. If there was an effect on taste, I am pretty sure that he would have learned this through the American Brewer's Guild, where he earned his degree.

Hmm... before I found this thread, I was advised that an easy way to aerate your wort was with a paint mixer attachment on a drill. So I bought one at Home Depot and gave it a good wash - is it safe to use this in my wort, even though it was intended (but never yet used for) mixing paint? Will 2-3 minutes of vigorous mixing with this thing on my drill sufficiently aerate my wort?

I think it's a stretch to call that thing a regulator since it does not regulate at all as far as i can tell. for the price of that kit you are half way to a O2 cylinder that would last for hundreds of batches if not more, a real regulator would be around $40 at harbor freight.
