Air Stone
 
I've been using an air stone for aeration for a few batches now with great success (much faster fermentations!)

However, after my last time aerating, as I was rinsing off my tubing and stone, the stone seems to have broke off. I figured I must have had a cheap stone so I went to the store and they seem to come in two varieties, cheap and cheaper. Anyone else have this experience? I am wondering if the no-rinse solution I used for sanitation this time may have played a part (are usually use a bleach solution)

I've talked to some of my aquarium friends and they've never heard of this happening before.

Are you talking about an aquarium air stone? If so, I would treat those as disposable...sanitize it, use it, throw it away.

In anyones honest opinoin, it the air stones really worth the trouble?

Yes! Anything you can do do oxygenate the wort prior to pitching the yeast is a good thing. Stirring it is good, shaking it is better, blowing air through an airstone is better still, and oxygen through a SS airstone is great. Gives the yeast a chance to go through a healthy multiplication cycle before the get down to eating the sugars.

That said, if you're pitching dry yeast, oxygen is supposedly not necessary. I'd still do it, IMHO...you just can't have too many yeasts.

hmmm, might have to give this a try. I would guess, from the previous post a couple weeks ago, that you would want a seperate tank with oxygen. :p

Question I have been waiting to ask... Just to be clear on this, pumping air with a regular aquarium pump, line, and stone is cool, as long as you sanitize the line and stone?

I would definately put a filter in line if pumping air. You'll be blowing mold spores and airborne bacteria if you don't.

You can get inline filters here: http://www.northernbrewer.com/aeration.html

I use one with welders oxygen.

It's one of the best things you can do for your yeast to ensure they're healthy and have suffecient populations to complete a clean fermentation.

Thanks! I could run the line through the hole in the top of the fermenter for the air lock (with room to spare for escaping air).... Another setup to put on my wish list... :)

I just used my system like the one ScottT mentioned (with the pure oxygen) in my Porter last Sunday. I didn't shake the wort at all... just put the SS stone in and let 'er rip for a minute. Mine has a long SS tube so I can move the stone around to distribute the oxygen bubbles. Sixteen hours later I had a yeast whirlpool and a three inch krausen. Not bad for a wort that started at 1080 (not corrected for temp) and I didn't have to throw my back out shaking five gallons of liquid. It's starting to slow down a bit now, but I'm quite sure I'll have a complete fermentation by the 7th day.

One suggestion for a new user: go for tiny bubbles. Don't crank the pressure up on these things or you'll be defeating the purpose of the 5 micron holes in the stone. That part wasn't mentioned in the instructions that came with my kit.

Was this an aquarium stone or a stainless steel stone made for homebrewing? I don't think the aquarium stone would be of any quality. The SST stone should not go into "a bleach solution". To sanitize that, simply boil it.



On the side, after brewing today, I'm placing an order with NB. One item will be the aeration kit. I'm waiting to try this oxygen I have. I wish I had it today!!!
