Fluffy solids wont settle. BIAB
« on: December 02, 2017, 06:05:58 PM »
Howdy all. Just wondering if anyone has experienced a fluffy solids accumulation after flameout that just wont settle. This is for BIAB, I use a whirfloc tablet and immersion chiller as pictured. The chiller makes it hard to achieve a good whirlpool but even still a whirlpool is no good if your solids wont sink...... After flameout I have allowed at least 30 mins of chilling to reach temps in mid 20s and still no settling occurs. Weird.

Once chilled to pitching temp remove the IC and whirlpool with your sanitary mash paddle , should form a decent trub cone that way if you allow to sit for 15 mins .
That's what i do with Glenboys fancy system and pull clear wort off all the way

You could always come to the dark side and no chill ?

I think I heard this can happen from using too much whirfloc.  The tablets are made for commercial use and 1 tablet per 5 gallons is overkill.  If memory serves, 1/4 of a tablet is enough.

How'd they turn out? 100% corn whiskey would be quite a sweet liquor?

Corns a bitch but the rewards are great.

1hr cook to gelatinise and then convert with malt or enzymes (or both).

The trouble with saying one hour cook is that it turns to something with the texture of wet concrete and has to be constantly stirred to stop scorching. There's work arounds, but it requires equipment.

Better when it's soured with backset too.

Looks like perfectly normal cold break, rather than hot break material from a whirlpool. If you get some in the fermeter, it will settle during cold crashing/end of fermentation. Some say it makes for good yeats nutrients. It can occur in no-chill containers over time, most people chuck the lot into the fermenter.
If it ain't half off, it ain't on sale!

Thanks for the feedback guys. Very helpful, I used half a whirfloc tablet in 18L so will try a quarter next time. I will also remove the immersion chiller next time and give an additional whirlpool a go. Good to know the cold break doesn't adversely affect the beer too.
Thanks again.

I have accidently dropped a whole tablet into 21L and not had break like that. Looks like you have just stirred it up.
I dont think the whirlfloc is casuing it, probs something in your grainbill with more protien then normal.
Its always a bit sad when a keg blows, kinda like losing an old friend.

I find grain from different sources produces significantly different breaks, especially cold break. German grain produces a huge cold break with proteins coagulating in much the same way as your pictures but Aussie grains, much less cold break.

With the german stuff and the fluffy cold break, I find whirlpooling is really the only answer. In my system, I use an external counter-flow chiller and recirulate back to the kettle setting up a whirlpool that runs for 20 - 30 minutes - plenty of time for the fluffy break to settle into a cone. Then slow the flow and into the fermenters with nice clear wort.

20-30 minute whirlpool? 30 seconds with a mash paddle is all I ever do. Why so long?

20 - 30 minutes is mainly for chilling, whirlpooling is a secondary consideration. It takes 20 - 30 minutes to take 50 litres of wort from boiling down to around 30C with my current system using the swimming pool and a submersible (basement) pump to chill.

I have about 3.5M of copper counterflow chilling capacity which probably should be about double that for better efficiency - one day perhaps.

Below are the exact reasons why I cant just copy a recipe from someone else .
Steve and Mark id like the chance to spectate on a brewday with both of you , even my filthy no chill brews get a solid trub cone just circulating after flame out and allowing to sit for 10 mins .
Still transfer to a sanitised cube at ~89 C and exclude all air and get straight into fridge .
So much to learn ! I'll bring Glen and a mop if that makes the deal

I get that exact same material every batch.  It clumps and settles to the bottom pretty quickly.
I BIAB and immersion chill.  I let sit for 30 min then rack clear wort to the fermentor.
As far as I know, that is cold break clumping and settling out normally.
