Flour after crushing, toss it or use it?

[kangabrew]

Hi,

I will brew with my new Grainfather tomorrow and today I started to prepare crushing my grains among other things.

I set the gap to a credit card thickness as per recommendations online, but I found the flour content to be a bit a too much, so I increased the gap a bit and crushed 4.8 kg of pale ale malt (10.6 lbs). Then I used a sieve to collect the flour and this is what I ended up with:



Would this result in stuck sparge / scorching in the grainfather? It amounts to roughly 4 dl (13.5 f.oz), but there is probably more as I didn't sieve it too carefully. Should I toss it? Worst case my OG will be a little lower.

You're overthinking this. That's perfectly normal and isn't enough to cause a problem. Put it back in with the rest of the crushed grain and brew on.

@BobBailey beat me to it. There's always flour. As long as that flour is mixed into the grist, you'll be fine.

If you're at all concerned about a stuck mash or sparge, add a small scoop (a couple loose handfuls) of rice hulls to the grain and mix in.

Rice hulls are cheap, cheap, cheap. They're 90 cents per pound at Ritebrew. I once bought 10# of them, and it was enough to fill almost half a 50# grain bag. I may not have to buy them again until 2023. I've began to add them every time, and I found they improve the lautering process in my setup. Cheap insurance, and things work better.

BTW, they aren't really necessary with BIAB.

use it. thats starch to be converted to sugars

I’ll echo what others are saying and add this: if you leave this out, your efficiency will take a hit. A little flour is normal. If you’re worried about stuck mash, I’d follow the advice and add rice hulls.

You could also do a multi step mash or a decoction mash - this will help break down some of the starches and help with efficiency. I don’t use a grainfather, so I have no idea if you can do multi step or decoction, but it would help.

Thank you all.

I did what you said - no stuck sparge, no scorching at the bottom.

I added rice husks, 5 % of total grain bill, which contained 1 kg munich, and 4 kg pale ale malt. The sparging water passed through with no resistance at all.

@Beerwildered multi step mashing is possible.

Yep, it was until a deer jumped out in front of me. Killed the deer, totaled the XLH, but I'm still here Got a few titanium parts now, but I'm still pretty functional.
