Is there any difference between the B3 $35 kit and the AHS $50 kit? Or the (gulp) $60 NB kit? Other than being in stock, I can't really see what you're getting with the more expensive kits - and shame on anyone who supplies a hose that's too short to reach to the bottom of a carboy!

Those small tanks run out REAL fast.I used one then just got a small cylinder from an oxy/accetalyne torch.I got some tubing for an aquarium air pump and a plastic air stone.I soak the air stone and tubing in sanitizer before use and have had great results with this set up.Of course I'm a mechanic and have a company re fill our tanks,so this probably Isn't
the best option for most.

If you have the budget, I will recommend the William's Brewing SS wand kit

WILLIAM'S OXYGEN AERATION SYSTEM
Item #:S78
Price - $49.90

http://www.williamsbrewing.com/WILLI..._SYST_P699.cfm

"Includes 22" Aeration Wand with a 2 micron stainless aeration stone, 4' of tubing, and an Oxygen Regulator for standard hardware store oxygen welding tanks".

Hope this helps.

Cheers!

There is evidence to suggest oxygenation is good, but recent studies suggest that pouring wort into the primary and rocking it a bit provides as much O2 as a stone can.

I did not conduct this study myself, but as a cheap and lazy brewer, the LAST thing I buy for brewing will be oxy related.

That study showed that shaking the fermenter was as effective as an aeration stone pumping air through the wort. Actually, shaking for 45 seconds was as effective as pumping air in for 4 minutes.

This is an oxygen stone (with an oxygen regulator); pumping pure O2 is more effective at oxygenating than shaking. A related study showed that an O2 stone can get 2 and 1/2 times more oxygen into solution than either shaking or pumping air can.

It'd still be low on my list of things to get.

This was absolutely not what that study showed.

Thanks for the clarification.

Close enough for me.

More o2 than shaking can provide has not been proven to make any measurable improvement in the beer. That's good enough for me.

We need this smiley added to the list here.

Glad I could help. I took the idea from one of Chris Knight's brewing videos.

Cheers!
