Hi,

I had a brew yesterday, and i noticed that i had crushed my grain way too thin!
It almost looked like powder.
What are the side effects of this?

I also somehow (massively) overshot my SG again. Any relation?

some days i feel like chucking it in....

Losp.

If you didn't get a set mash then you may get a bit more trub in the kettle but maybe even an extra couple of points of efficiency.

I've set my new mill to a far finer crush than the old one.

Im pretty sure that if you crush your grain too thin you will smash up the husks releasing tannins and off flavours, minor though, also you create more of a chance of getting chill haze from the same problem.

If your not BIABing your sparge runnings will gum up giving you a stuck sparge ( reduced flow) which is super shit, It happened to me when I was using a blender to crush grains. BIABing , no problem, but the finer particles get through the bag which is not ideal for clarity or smooth flavours.

And lastly you will find that your efficiency will actually rise if the grains are crushed more due to the greater flow of water and mash enzymes that gets into contact with the starches and such. This will make you over shoot your SG if you have set your efficiency estimation too low. Just adjust the efficiency up for your equipment for the next batch.
If your using brewing software that is......

Well dont give up mate you will get it sooner or later and you will think all this stuff is easy as, just keep learning, and keep at it.
The beer only gets better.

As Bryan says.

The "standard crush" is aimed at mash tun / HERMS brewing and is a compromise between efficiency and flow rate with the basic idea that the husks form a grain bed to filter out particles. With BIAB the "filtering" medium isn't so much the husks, it's the material of the bag.

When God created Swiss Voile he did so with this in mind as he realised that up to that point the only useful thing to come out of Switzerland was the Cuckoo Clock.

:icon_offtopic: Then he did CERN and thus HTML so we could view porn but that was later.

Go God. :icon_chickcheers:

Agreed, I quite often view porn on the internet while waiting for my mash or boil. Thank god for Swiss voile fabric, HTML and Swiss army knives I say. :icon_offtopic:

Thanks everyone for the responses.
I reckon now its my Drill, that's causing it to crush so thin. I might go old school and by a hand crank.

About the overshoot. i was aiming for 1048. And got 1060 surely thats a bit much? I tested my hydrometer as well to make sure that wasn't odd.

Also i am a 3Ver.

Cheers

And let's not forget the best thing of all to come out of Switzerland...

Swedish backpackers. :icon_cheers:

Huh? I thought Swedish back packers were from Finland?
Lol.

And also I guess your efficiency is just a lot higher than you are allowing for so simply adjust your recipe to allow for a higher efficiency.

Beersmith tells you what your sg should be and if you change it from what it tells you it changes your efficiency to suit. Bang.

I thought they came out of Holland, or was it The Netherlands?

If you didn't get a stuck sparge, I wouldn't be too hasty about changing your mill settings. You have picked up a shit load of extra gravity points & I assume you will dilute before you pitch your yeast. The plus side of that is extra wort to ferment. I would just adjust your efficiency settings in your brewing software (if using one) to bring it back in line with your actual results, maybe 80% +.

And let's call the place by it's proper name, The Netherlands.

Holland (North and South) are only two 12 provinces which make up The Netherlands.

A bit like referring to Great Britain as England. Commonly done, but wrong.

If you crush your grain thin, do you end up with thin beer?
