It is infected! I know that. I brewed NB's Oud Bruin kit a few years ago and pitched the recommended wyeast roeselare blend. Went through a suitably long primary, secondary, and then I racked it off the cake into a tertiary carboy for aging. This beer has been in carboy 3 for two years next week!
M aging carboy is a 5 gallon, so its full up to the taper of the neck (figured it would minimize oxidation and whatnot, plus what the heck else can I do with a free 5 gallon carboy?)
so that's the story, here's the question. This is my first "wild" brew, and I am wondering how big an issue it would be if the carboy bung got knocked off? This carboy lives in a seldom used corner of my beer/guitar/man stuff room, but yesterday I was messing around in that corner to plug an amp in. I noticed this morning that the bung was on the floor (must have hit it with a cord), so it probably sat open for 20 - 22 hours.
I know it's infected with what I want, but are the "good" bugs resilient enough to keep other stuff from infecting it if it was open? any foreseen issues? I plan on bottling at the end of the month. I'll add pics from my phone shortly.
