I was bottling off some NHC entries last night, using my "counter-pressure filler", aka racking cane shoved through a stopper. When I got to the fifth and final bottle, I could tell the keg was about to blow. No problem, I thought, this one may be a little yeasty but it'll settle out. I got it filled (barely) and bled off the head pressure as usual, then pulled the filler out. Normally at this point there's some foam but I have time to get it capped without losing much, if any beer.
Apparently that isn't the case with all those little yeast flocs providing nucleation sites. As soon as there was a path out, the beer *geysered* like nothing I've ever seen before. I let the bottle settle down while I was cleaning, and literally only ~3 fl oz of beer was left. The rest ended up on the table, floor, walls, dog... I was soaked from the waist up. I thought I got it all cleaned up but this morning I found some on the vaulted ceiling, about 22 feet up. I guess I'll be re-brewing this one.
No particular reason for sharing other than that it's a potentially funny story and maybe a PSA: don't counter-pressure bottle yeasty beer.
