Floating Krausen!?!

Post by mrboxpiff » Fri Jun 16, 2017 9:15 pm

Probs this has been discussed before, but my recent brews always seen to have this bready crust on the top of the wort in the fv. I think I'm right in calling it the Krausen, or something like that. It makes it a whole lot harder to Syphon off without sucking this lot up. Any comments or suggestions on how make it sink?
TIA

mrbox,
Why make it sink? You could put your syphon tube in one of the big gaps, drop it 20mm below the surface, bring tube to side
of FV and syphon from there, always keeping an eye on the tube as the level drops.
Or you could use one of these http://www.ebay.co.uk/itm/AQUARIUM-FISH ... rkt%3D1%26
Sanitise the net as normal, 2 days before you are ready for bottling use this to gently scoop up all the muck, only immerse the net 5mm below the surface.
The next day, anything that was left behind should have sunk (tiny bits). If not, scoop off the rest. Then bottle to your hearts` content! :D
That`s what I do and never had a problem.

Many thanks for your reply and advice. My experience is that more crud gets into the Syphon if it floats, so I may well try your scooping idea
Cheers

Just wondering did you use a large amount of irish moss or protofloc in this as I have found to much causes the yeast to float in clumps but can't find much confirmation.

Are you sure it's finished? There are some strains of commercial yeast that does this, Cullercoats springs to mind. In the latters case the brewer keeps "beating" the yeast back into the wort during the fermentation. If it has definitely finished but continues to sit on top rapid cooling could help it to drop.

I wondered about rapid cooling. And Simon12, I probably do use slightly more protofloc than recommend, so that's an interesting thought and I must try using less. I'm wondering if anyone else has experience of this?

I severely doubt Protafloc has anything to do with it. It's job is to coagulate proteins and polyphenols in the boil. Over use can result in filters blocking but that's about it.

Us 05 can hang around for ever if it's to warm so certain strains will not drop easy ...
But looking at that it looks more like coagulated protein rather than the krausen.
Do you use temp control on your fermentation....

I never thought it would but have found it does

Yes I use an inkbird for temp control in a fridge so a consistent temp isn't a problem. Should I drop the temp right down after fermentation has finished?

Yes. Cold crashing also helps drop out proteins that cause chill haze so worth while all round.

As Orlando said.
I always crash cool now to help with clarity especially when kegging.
