So here is an article from BYOB http://***********/stories/techniqu...66-hot-side-aeration-a-storing-hops-mr-wizard
Good technical brewing literature is very expensive and is not posted for free online. So it's hard to give you good reference to the actual chemistry. But the bottom line is, maintaining water an inch above your mash bed prevents excess oxidation and helps to evenly rinse the mash bed of extract. I will tell you another thing oxygen is the biggest concern of brewers, even more so than bacteria. We use a very expensive sensor to test our beers for oxygen and anything above 20 parts per Billion, yes Billion is unacceptable. High oxygen can ruin a beer in a matter of a few days, before it has ever left the building. Even a bag of potato chips is purged with gas in order to prevent oxidation. I am sure you take good care of your coffee beans, I sure do. I am just trying to help people out, you can lead a horse to water but you can't make it drink. I'll draw a diagram of a trombone and post it. Good practices will make good beer, don't stress out, but make sure you take care of your wort and you will make cleaner beer.
