I've never had an infection in my beer that I could put a species name to, but they've all tasted like #%^%^&. If I knew for sure I had an infection, I'd dump it and bleach the bejeezus out of everything. Then again, I'm sure it conforms to one or the other of the wort infections Belgians like to call beer. I kid the Belgians - because I care. You aren't Belgian, are you?
