What the heck was that?

I was getting ready to chill the last few bottles of a batch of Pilsner and I noticed one of the bottles had what look like a stain running down the side. I wiped the bottle down and determined it was on the inside. Looking closer i noticed a couple of darker colored nodules in the sediment, maybe the size of a lentil. Not liking the looks of it I decided to pour it out. The bottle had not been shaken or jostled in any way but when I popped the top, a Grolsh bottle, it sounded like a champagne cork had been popped and all the beer in the bottle shot out like a geyser.

What was that all about? i am guessing nothing good.

Sounds like an infected bottle. If the rest of the batch so far has been fine, it's probably just one bad egg in the bunch. I wouldn't worry.

All it takes is a little bit of missed crud during bottle cleaning, and you wind up with an infected "gusher" like that one.

I agree with the above post. Also, since I noticed you're using a Grolsh bottle, double check the gasket for any cuts or cracks since those can harbor bacteria like nobodies business.

Infection, also sounds like that bottle didn't get washed very well. That "lentil" in the bottle sounds like a leftover "yeast slug".

Thanks for the responses. Good tip about the rubber gasket. Will take some extra care next go.

When checking the gasket for nicks or cuts, also take it off and clean and sanitize both sides of the gasket and the ceramic/plastic part the gasket goes on.
