Homebrewing Aeration/Oxygenation Experiment

There is a lot of discussion going on in the homebrewing community about the necessity of getting oxygen back into your wort after a full boil. There are several methods being used and not everyone agrees on the best bang for the buck (shaking the fermenter or pure O2 injection). I personally experienced some empirical evidence that O2 injection was benefitial but I was hoping to confirm or deny this in a more scientific way. Ok, so it's been six days since I pitched on this experiment. If you recall, I posted that at 45 hours after pitching (remember the OG was 1.050): #1 = 1.018 (64% attenuation) #2 = 1.019 (62% attenuation) #3 = 1.016 (68% attenuation) After 70 hours, the SGs were: #1 = 1.016 (68% attenuation) #2 = 1.015 (70% attenuation) #3 = 1.013 (74% attenuation) After 144 hours or 6 days, the SGs are: #1 = 1.012 (76% attenuation) 5.1% ABV #2 = 1.013 (74% attenuation) 4.9% ABV #3 = 1.011 (78% attenuation) 5.2% ABV
