Cider Gone Crazy!!

[phendog]

Put a 5gal batch of cider together 7 weeks ago and used White Labs Liquid English Cider yeast - OG: 1.065.

Racked into secondary 10 days ago at 1.010. Took a reading today and seems gravity is stuck at 1.008. I have another batch in secondary where I added 3lbs of fresh cherries. Anyhow,... decided to split a pack of US-04 between the two carboys and let finish to ~1.002.

After putting the stopper on one of the carboys, I bumped the bottle on the one sitting next to it and BAM!!! Co2 started releasing like crazy and nearly turned my airlock into a bottle rocket! I hope the video attachment works - not sure what happened. Is it possible that the CO2 was clinging to the bottom? Someone please explain this to me.

When you bumped it you probably just knocked a bunch of CO2 out of suspension. That is a lot of CO2 though. Was this one of your ciders that's in secondary? It looks like my meads do when i degas them after like 3 days of fermentation.

Maybe there was still some fermentation happening in secondary that you didn't know about. That seems like way more CO2 than would just be hanging out in suspension, especially after racking once (if it was already in secondary).

Agree - that is a ton of CO2 - it raged like that for well over a minute and then took another 4mins to calm down. It looked perfectly clear and still prior to the bump. More CO2 than what seems reasonable to be clinging to the sides or bottom. It was in a secondary and started in a primary with a 2nd generation yeast. Essentially I dumped right on top of the last batch after I racked it out.
