It's a vigorous up and down action. Up & down, up & down, up & down...until BAM...you have foam.

Then I usually have a cigarette.

Hmmmm.... I guess I would need a bigger pot to attempt this.

i pour my brew kettle through a collander into a bucket, drain the hops, toss, and pour into another bucket, through collander, than back again. usually lose a pint to froth overflowing.
my last ferment took off in four hours, and my blowoff keeps cloggin. i would say this areates enough, and takes maybe 30 seconds.

I do the back and forth between a bucket and the brew pot. It kills the back.

I guess then, at that point, it's too late for the protein rest.

Why bring up air stones?
Because many people use them. I did for a while and I still have the SS air stone (or diffuser...whatever it's called) and aquarium pump but it does take a while and I felt the wire whisk was just as effective if not more so and faster.

Quote:
Bubbling with O2 seems better to me.
That's supposedly the best method but I've also read to just bubble O2 through PVC tubing and forget the stone because the stone is only marginally more effective. My understanding is that the 'tiny bubbles and increased surface area' is greatly over-rated and the majority of aeration still comes from surface agitation (I know it does in aquariums but those aren't 2 micron stones either). But I'm still not sure and more than willing to be proven wrong.

FWIW, I use the wire whisk to get it aerated as much as I can...then I pour it through a strainer and into the fermenter which aerates it a bit more...then I shake the hell out of the carboy...then I pitch and shake it again.


Huh-huh...he said "2 micron stones"...huh-huh.

Biermuncher to boiler pot: Was it good for you?

Thanks for posting that GilaMinumBeer. From that article you linked:
Quote:
Pumping air through a stone is not efficient.
Splashing/shaking is good up to ~8ppm.
Pure oxygen is easiest and most effective with most control. This is good up to as much as 26 ppm @ only 60 seconds.
They did use a stone with the pure O2 but didn't mention whether they compared pure O2 with stone to O2 without stone.

good powerpoint

since i do not have a pure O2 set up here's what I do to get oxygen in.

I dump the boil pot into primary. splashing as much as possible.
then i put a tennis ball under the primary and rock and shake like hell.
i usually do this for 10 mins in 5 min incremenents. then i move it from my upstairs kitchen to my basement and i make sure that shake it as i do this move.

that ppt was interesting because it seemed to say that there was a max you would hit shaking no matter how much you shake.
