So I did my second AG batch today and everything seemed to be going very well. I actually got about 80% BH efficiency, hit my preboil volume, and started brewing. It was all good until I got to rack to the fermentor. I had an absolutely inordinate amount of trub and ended up having to siphon through a lot of it just to get about 4 gallons of wort instead of the 5.25 I had tried to shoot for. And the fermentor looks like it is full of diluted oatmeal... Very thick and gritty looking.

I had to drop my friend off back at his house while I waited for the wort to chill and by the time I got back it was at 62 deg F. Dunno if that was related to why I had so much trub.

PS - Will I be fine to just let what I siphoned into the fermentor settle and maybe do a secondary in about a week or two to clear it out?

Anyways, here is the recipe I brewed:

Mash Ingredients
Amt Name Type # %/IBU
10 lbs Pale Malt, Maris Otter (3.0 SRM) Grain 2 80.0 %
1 lbs Oats, Flaked (1.0 SRM) Grain 3 8.0 %
8.0 oz Biscuit Malt (23.0 SRM) Grain 4 4.0 %
8.0 oz Special B Malt (180.0 SRM) Grain 5 4.0 %

Mash Steps

Mash In Add 16.00 qt of water at 163.7 F 152.0 F 60 min
Mash Out Add 8.40 qt of water at 200.7 F 168.0 F 10 min
Fly sparge with 2.15 gal water at 168.0 F

Boil Wort
Add water to achieve boil volume of 5.75 gal
Estimated pre-boil gravity is 1.054 SG

Boil Ingredients
Amt Name Type # %/IBU
First Wort Hops
Amt Name Type # %/IBU
1.00 oz Fuggles [4.20 %] - First Wort 60.0 min Hop 6 14.4 IBUs

1.00 Items Whirlfloc Tablet (Boil 15.0 mins)

Here's a picture:

^ That isn't right... We're talkin about 3 inches or so of trub settled in the fermentor after 20 minutes.

It'll compact over time after fermentation finishes knocking stuff around. You might end up losing half a gallon or so to trub. Lately I've been trying to limit the amount going to the carboy because it takes up space beer could be in. Last beer I neglected to and lost a little more than 1 gallon to trub and hop sludge from dry hopping.

I have had batches that look like that when I use oatmeal. but it will compact down when the yeast falls out.

FWIW, I've begun scaling my batches to 6gal to account for about a gallon of kettle trub loss, chill shrinkage, and fermenter trub loss. That way I actually yield 5gal to keg and/ or bottles!

Wait. You're not talking about beer, right?
You're talking about beer. That could have been a whole lot more fun.

I have seen many threads contributing all of that trub to the whirlfloc. I only have an 8 gal kettle so I skip the whirlfloc and sacrifice some clarity so I can maintain my volumes.
No yeast, no beer. No beer, no civilization. Therefore, we really have yeast to thank for all our modern-day conveniences and tasty beer

Nice looking batch of break material. I've gotten some that looked like that. I use a bucket fermenter and dump it all in. In a week you won't know it was ever there.

Yep...that'll settle to an inch or so, plus the yeast. As others have said, I adjusted my recipes(boil) to about 5.5 to 5.75 Gal to assure a 5 gal end result.
Screw it, Lets brew it

Primary 1- BM's Cream of three crops.
Primary 2- Paleface Scalper
Primary 3- Monks Reward (Kreuzberg)

That's nothing man. This is what my ipa looked like. After that I immediately built a hop spider. It will settle to at least half that size.

That just means you got a good cold-break. That's a feature not a bug--nice job for your second AG batch.

Piratwolf has the right idea, plan for 5.5 to 6 gallons into the fermenter depending on the amount of hops you're using.
