I'd like to get a better handle on the science behind brewing and was just wondering if someone could give me a better explanation on why oxygen is bad for the fermentation process. From what I've read in How to Brew and a few posts on the forum, you risk contamination and also it can stale the beer quicker. But what i'm after is why this is? I guess the contamination part is kinda self explanatory but I'd still like to learn some more about how oxygen reacting with the wort at that point would cause it to stale.
