Just opened a bottle of german altbier I brewed from a kit and ended up with a slowly, overflowing bottle. there also appears to be, at the bottom of the bottle, a blackish-brown sludge mixed with the yeast. Here's a picture:
It's clearly an infection of some sort... but with no horrible flavors or anything. I'm currently drinking it... Has anyone else experienced this? Should I be concerned? haha.
Yay homebrew!
