I am brewing a barleywine this weekend. Last time I tried barleywine, my fermentation stalled and I ended up throwing the batch out. This time, I am getting setup with a starter and oxygen system to avoid any possible problems. I have a welding O2 bottle, regulator, filter, and .5 micron diffusion stone.
My main question is how do I know once I have enough dissolved oxygen? I know that a lot of people say to just run the oxygen for 1 minute. I have also seen people who have bough meters to take measurements. However, I'm pretty sure there has to be a better way.
We can know the temperature and specific gravity of the wort and the partial pressure of the oxygen. Given these things, would it be possible to take a desired level of oxygen saturation, say 12ppm, and calculate a temperature at which a given wort would saturate to that level?
For example, if I knew that at 171 degrees my wort would max out at 12ppm on pure oxygen, I could stop my wort chiller at that moment and run the oxygen for several minutes to saturate. Once I feel reasonably confident that I am saturated (not exactly sure about this), I can turn off the oxygen and continue to chill.
Does this sound reasonable, or am I just crazy? If so, is there anyone who could help with the calculation?
