So there are a lot of references out there about how Brettanomyces can metabolize micro-oxygenation. But how much is too little? I'm not talking about 100% Brett fermentations or fermentations that rely on Brett to do the primary fermentation, but secondary fermentations of Brett that are geared towards producing those funky and fruity esters/phenols that we are after (or other beneficial processes from Brett that require O2). I've often read that Brett produces a lot more "funk" when under pressure in the bottle or a keg.
Is there any solid information out there, scientific or anecdotal, that shows that no or too little exposure to oxygen produces undesirable results from any Brett species/sub-species in a typical sour beer? In other words, is oxygen really needed in order to produce desirable results from any Brett sp in an aging environment?
