TLDR - half of a 2.5 gallon batch came out of the fermenter into an open bucket after 1 day of fermentation, and I poured it back into the fermenter. Is it for sure oxidized and ruined? Or will the yeast cleanup that oxidized portion as it is early in fermentation?
Long story : I wanted to try a new technique out of pressurized fermentation in a corny keg. I planned on fermenting in the corny keg using a spunding valve, and also serving from the same corny keg using a floating dip tube. So I brewed a german wheat beer, and put the wort into the corny keg, tossed in the yeast, set the spunding valve to 22psi (so when I cold crashed it would come out at 2.4vol). However, I was tired as it got late in the night waiting for the wort to cool, and I accidently hooked the spunding valve up to the "out" port that was on floating dip tube side. When fermentation started and built up pressure it started spitting foam out the spunding valve. I thought it was just excess krausen coming up and out the top of the gas port, however it was foamy wort coming out the liquid port through the floating dip tube. I had setup a bucket to catch the intiial "excess foam". I come back 6 hours later and over a gallon of beer is now in the bucket. I picked up the keg and it was half full! Half the beer had been pumped out. So, it was either ferment the 1 gallon that was left, or add the expelled wort back into the mix, which is what I did. My question is now am I already screwed in terms of oxidation to that wort/beer, or is it early enough? Krausen was going strong at this point, basically the first day of full krausen (36 hours after pitching)
Thanks for any help!
