General Homebrew Discussion / cold side aeration and staling reactions
« on: December 13, 2009, 05:03:12 PM »
Could someone explain, or point me to some info on cold side aeration and it's effect on decreased shelf life, or staling reactions?  I'm not 100%, but I suspect that there would be a difference if you take some cool wort, aerate it, then divide it into two containers.  The 1st container is pitched immediately with the appropriate amount of yeast, the other container is pitched several days later, (3-7 days)

In the 1st container the yeast would scavenge all the O2 they need right away, while in the second container the 02 would be free to react with various wort compounds and decrease the shelf life and increase the staling of the finished beer.  This is of course assuming that your sanitization practices are perfect.  I'm not interested in hearing about problems related contamination issues.

Which compounds are responsible for staling/oxidization reactions?
Is my thinking correct?
