Just received my Dec issue of BYO and there's an interesting article on "Aeration" by our own "Bill Pierce".

The article covers all the methods of providing O2 to the yeast in the fermentation vessel. Sooooo--

I am interested in how others on this board inject O2 into the wort.

As for me I use the "Wort Wizard". It snakes around from the kettle on the patio upstairs, for 75 ft. to the fermentation room in the basement below. I run the wizard for about 30-45 min's after the carboy is filled. I also use one of those Wine Stirrers and attach it to a drill to stir the wort and provide more O2.

Actually I don't know if I am supplying enough O2 to the yeast or not!

Also Good Article Bill!

When you say you let your wort wizard run after the carboy is filled, are you aerating it with "outside air"? I might worry about it sucking in some nasties, but maybe I worry too much. I know they recommend a filter when using an aquarium pump. I use pure 02 and a stone myself. I have the stone weighted down with a stainless nut so it goes to the bottom of the fermenter.

Actually I am. I am sucking from the hop bed in the kettle. Usually through the hop filter. Never a problem so far!

Thanks for the compliment, michael. Myself, I use the Bernzomatic disposable O2 cylinders and a stainless aeration stone. I keep thinking I'll find an inexpensive welding regulator at a garage sale one of these times. I admit to being a cheap homebrewer and not wanting to pay top dollar for a new one.

Michael, I did the same thing on my last brew with my wort wizard, but then after a few minutes I got "paranoid" like I do sometimes. I have the same thing Bill has, and I have to say that it has improved my ferments well.

OK, The regulator used for welders 02....so is the same type regulator used for both 02 and whatever the other tank is? I run across welding regulators fairly often at yard sales/flea markets.....saw two last weekend.

Connie the 02 regulator is just used for oxygen. I'm assuming the other tank you're referring to is an acetelyene tank(usually red or black). Some regulators however can be used for other gases if you change the tank fitting on it. Sometimes the gauges would have to be changed also. An oxygen regulator should have a green faced dial on the gauge somewhere, at least the newer ones do. Acetelyne gauges usually have a red faced dial on the gauge.

I also liked the DIY transparent inline oxygenator project. Is clear schedule 40 PVC T's, caps, and tubing hard to find?

I have a small medical O2 tank that I hook up to a 24" aluminum tube with a 0.5 micron aeration stone on the end so that I can get it to the bottom of my Sanke fermentor. I usually blast pure O2 for about 2 minutes. Seems to work pretty well.
