Besides the Culligan water once, what is the source of your brewing water?

Oxidation is essentially what brewers worry about but is not much of a real concern. It can happen but its difficult to do.

This is not my experience as a homebrewer, nor as a judge. Next to ferm temperature related off-flavors, Oxygen related off flavors/flaws is the next biggest culprit.

From what I've read about oxidation it's more of a sherry wine flavor or sweet flavor which what I'm describing is the opposite of that.

It's everything from "Stale" to "Grassy" to "Musty" to "Carboard" to "Wet carboard/wet paper" to "sherry/port" (in it's most advanced stages. I've tasted it in all those stages. It can range from subtle to extreme.

Go to the BJCP flashcards, do a control F (or "Find" or "search") for "Cardboard.

PS, this is getting off topic. I didn't say you were experiencing Oxidation. I was responding directly to this quote:

PPS, I think your beer has fermentation temp off flavors. But that's as close as I can come without tasting the beer based on the descriptions you gave us.

Thanks for the chart. I would say that it's most like a 'solvent like' flavor. My guess is that it's from high fermenting temperatures as many have also said.
