Yeah spider it's weird for sure, it doesn't taste infected at all. I guess a wild yeast could have made it in at some point, but I'm pretty meticulous about sanitation and this would be the first beer in a few years to go south. When I put in the 099 it took off like a mild second Krausen for a few weeks then settled down. My fear would be if I blended it, the residual 099 might eat away at the other beer. Guess I gotta did a way to kill the yeasts. Maybe campden tablets?
Campden doesn't KILL yeasts; just stuns them.
I say "don't throw good homebrew after bad".
Set it aside in a container you don't need and let it age for a while like bugeater recommended and get on with making your next home brew. (Or dedicate two days and batches to making crap home brew slightly less crappy.)
1.004 IS pretty odd, even with 099.
