oxygen

[billy frank]

I was under the impression that boiling the wort knocks excess oxgen out of the solution, so it seems that just adding ice would introduce a bit more oxygen. I know that goes against basic chemistry theory as two hydrogens and one oxygen make one water molecule, but oxygen can be absorbed in excess in a regular water solution. I don't know how much oxygen can be stored in ice, must be a question for the chemist's. I myself use an immersion chiller, and it works fine.

I have a friend that uses an air pump to add oxygen to his cooling wort, and that works fine I guess. However, I don't do anything, outside of just making sure when I pour into my fermenter I make sure is splashes around a lot. I pour it a little slower, and high enough that it foams up. Mine seems to ferment as good if not better than his. I know you need oxygen in there, but the amount of it and techniques to get it there may be a bit over reated. Thoughts?
