More effective than pumped air with or without a diffuser stone. They did not test pure O2. Granted, I haven't made a beer over 1.070, but I have never had a problem with rocking not introducing enough O2 (if fermentation start and attenuation are accurate guides). | |

| Nov 30, 2010 at 17:26 | comment | added | Fishtoaster | For completeness, Palmer says that ideal oxygenation is 8-16ppm (How To Brew, 2006, page 70). | |
| Nov 30, 2010 at 16:33 | comment | added | Brandon | Plus, how much variance in temperature can you really expect? This is for 75°F - I wouldn't expect anyone to oxygenate more than 5 or 10 degrees cooler. | |
| Nov 30, 2010 at 16:28 | comment | added | Brandon | I would certainly agree that the saturation point increases, but I'm not sure that the RATE of solution varies much with temperature. Can you quantify your edit? Or provide a source? | |
