I agree on sample #1 and 2 being nearly identical, but my current conclusion is that #3 was the stronger ferment at 43 hours. Depending on your hydrometer, the scale can be such that 1.019 to 1.016 is about 3/8ths of an inch.
I agree with the first point in that a lot of people take what they hear or read a little too seriously. I was hoping to give a little more validity to some of the claims and take away from others by doing this simple test. I may repeat the test myself using better methods and just for the sake of repeatability and confirmation of results but it would be a better if others try the same experiment (confirmation of peers and all).ColoradoXJ13 said:...I have been seeing a lot of non-scientific stuff on this board, a lot of speculation, and a lot of opinions that are unfoundd. ...and as clayof2day said, you need to repeat this experiment a bunch of times...
ColoradoXJ13 said:Personally, as far as my 'brewery' goes, I am going to try to spend as little money and keep it as simple as possible, and this includes pitching and shaking. But then again, boys love their toys, I drive a jeep with well over $5000 in modifications that are totally not necessary...to each their own.
That being said, I am not even close to hitting most attenuation numbers, i think the LME from my shop sucks, but I am still going to bottle it when SG's are steady and bottles will not explode.
I think we all want to keep it reasonably cheap and simple, but we all want to improve our methods otherwise we wouldn't spend so much time on this board. It's interesting that you decided that your attenuation is the fault of your LME. I suppose you can try another brand or go to DME, but then there are other variables to consider. What if 5 brewers repeated my experiment and it was a conslusion for all that O2 injected wort always finished with the lowest gravity? Would you buy a tank?
