Floting Yeast in the top of bottle

Bartuken · Mar 23, 2016

Hi brewers!
I'm becoming crazy right now. I have read a lot of post but cant find anything about what is happening to my bottles.

It's like a Yeast ring around the top of the bottle but with some particles in the middle.
Maybe Its only sugar/yeast combination, or contamination

What do you guys think?

Here is some photos:

Also left 10 days in the fermenter before bottling

YOU CAUGHT ONE!!!!! You caught one of the illusive bottle Krausens in their natural habitat!!!! I've only seen 1 in 10 years of brewing. CONGRATS!

Bottle krausens form more often than folks realize. More than likely in the case of the last bottle you picked up a lot of sediment, enough that you're actually seeing krausening.

People seem to forget that carbonation is just another fermentation, except in a mini fermenter that we've clamped the lid on extra tightly. If you're brewing with ale yeast, which forms a krausens during fermentation, why would you think it would suddenly change genetically at bottling time, and NOT do the same thing? Most of the time we don't notice them, because many of us just shove the bottles in the closet for 3 weeks, and also they more than likely form really quickly and then fall (forming the sediment layer in the bottom of the bottle, just like a layer of trub in a bucket or carboy) probably within the first few hours of carbonation.

And usually only nervous noobs bother to watch their bottles carb, so only they tend to notice them, which usually adds to the panic. But they're only seeing them, because they tend to hover over everything more than anyone else.

I've heard people who prime with DME usually notice them more than anyone else.

How long ago did you bottle ?
Sometimes, when racking from the fermenter to the botling bucket a lot of yeast goes with it .
When priming with sugar and botling, if there is a lot of yeast in the botle, it will ferment vigourously again for a couple of days and then settle out to the bottom again.
Do you have a bottom yeast ring quite pronounced? That would indicate a lot of yeast.

If yes....not a problem though

I bottled last sunday.
In the bottom of the bottled seems to be more yeast.
Thx god it's not contaminated!

Maybe this is a high-lvl of yeast and sugar combined in the bottled?

I use corn Sugar.

Sorry for the questions.
I have to be exited? because I'm!

This happened to me with a batch that I overcarbed accidentally. Definitely not a problem, and will probably drop out when the bottles go in the fridge.
