Wort Oxidation

[Bonestar]

What are the signs that your wort may have been oxidized during sparging?

That would be hot side aeration. While it does happen, it's nothing to be concerned about as long as you have a healthy fermentation. The yeast will clean it up and you won't have any noticeable effects in your finished beer. Listen to the brewing network's brew strong on Hot Side Aeration with Dr. Bamforth.

As long as your fermentation goes well, it's pretty much impossible for you to oxidize your beer during sparging.

Think about it. You're going to boil, which drives off pretty much all oxygen. The next thing you do (after cooling the wort) is shake/sir the crap out of it or bubble air/oxygen in it... for the purpose of getting oxygen back in there for the yeast.

Yeast require oxygen in the growth phase of fermentation. Some high gravity beers (esp Belgians) actually have you oxygenate the wort after fermentation begins.

Once the yeast hit their anaerobic phase, oxygen is bad and can damage the beer. Pretty much any time before visible fermentation begins, you run little (no?) risk of damaging the beer via oxygenation.
