Default What is the best way to aerate?

I am trying to get my mind wrapped around the aeration process. What is the best way to aerate and is it something I can get anywhere are do I need to go to a brew store?

The best way is probably with an oxegyn tank. The easiest way is pour the wort into your fermenter. I drain my kettle and let the wort fall into the fermenter from a foot or two this seems to aerate the wort quiet well. I am sure others will give you more ideas.

There will probably be many responses as to what is the "best" method of aeration. Some people, (like the previous poster) use an oxygen tank and an aquarium filter stone. Other people use an aquarium pump and stone, but with plain air, instead of oxygen. Many people like to pour the wort back and forth between the kettle and fermenter a few times.

I have a large restaurant spoon that has about 30 holes in it. After pouring the wort into the fermenter (using the splash/pour method), I like to aggressively stir the wort with the "holy spoon" until it is frothy and foamy. Then I pitch the yeast. This method has worked very well for me, even on high gravity batches. I have fermented a Tripel that started at 1.080, and a Russian Imperial Stout that started at 1.092 using this technique with no problems whatsoever.

I have a paint mixer hat I attach to my drill and go nuts for a few minutes.

I like the paint mixer idea attached to a drill. I tried three different ways, shaking my carboy, aquarium pump with in line sanitary filter to a stainless steel diffuser, & finally an oxygen tank directly to my stainless steel diffuser. They all work, but the oxygen is the easiest & fastest acting by far. I bought an oxygen tank from a gas supply company (small 20cf bottle) as well as a regulator with a ferrule that allows me to attach a hose to it. I sanitize the diffuser & the hose, drop it in & blast my wort for 30-45 seconds, done. The first time I used it, my fermentation began within minutes & it was aggressive. Here's a video of that fermentation:

Where did you get you stone from and is it a stainless steel stone?

Shaking your fermenter seems pretty effective and it doesn't require additional equipment.

I'm pretty sure that's how commercial brewers do it.

See http://maltosefalcons.com/tech/yeast-propagation-and-maintenance-principles-and-practices for some good information, but she didn't try a paint mixer.

Oxygen tank is suppose to give the max oxygen compared to the aquarium pump or shaking/mixer methods.I like shaking it every hour or two . I just use a paint mixer but i get a good foam pouring it through a strainer but i still mix for about 5 min. I would like to try the oxygen system some day.
