Good to hear. I actually used some pretty old yeast in this one that was resurrected from a bottle of a similar recipe I brewed a year ago. See thread
here. So there was a few extra infection opportunities in this one.
I was checking out the infection thread and mine isn't "bubbly" like those infections, but there is definitely a skin and some white floaters. Maybe just remnant of the cocoa...
