Wetting grain before milling

Unread postby Luis Coentrao » Tue Jun 03, 2014 11:30 am

Hi,

Has anyone heard about "Wetting grain before milling ".
It seems that prevents husk damage, improves in lautering and mash efficiency.
I saw some guys talking about this in the AHB forum.
The proccess should be something like this: "1/2 cup of water to 5kg (...) put the grain in a bucket and stick the hands in and stir through the water (...) let the grain sit for 5-10 mins to allow the husk to soften."

Any comments?
I have never try it.

I tried it once....never again :lol:
I ended up with porridge in my mill...not worth the hassle in my opinion, although I do know that others do it with some success.
The worst thing that can happen if I die is that my wife will sell all my brewing equipment for what I told her I paid for it

It all depends on the amount of water you use.

I've managed to get good results in my Pre-BM life, you can find some details at BrauKaiser

I don't know how it improved lautering. Probably because the husks are less damaged when you do this wet milling. But... for the Braumeister you'll have to mill with a bit wider gap than other brewing installations, so I don't see a big advantage of doing it for a BM brew.

I do this all the time and follow Troi Kaisters method from his website Malt Conditioning it works for me :)

i do it as well sometimes, when i think to do it. if i'm in a hurry to get the mash on it's the first thing i skip. you need to really mix in the water well, and then give it 10-15 min to soften the husk, then they are indeed (in my experience) less likely to shear. i only do it for base malts. i have to say, since i get good circulation without conditioning, it's obviously not necessary.

If I look at the photos of that conditioned wheat it might be a good idea to try it with my next wheat brew...

Thanks for the posts, quite usefull!
However, I still remain with some doubts,

Considering that, sparging and lautering are not fundamental steps when Brewing with a BM, I do not find real advantages in wetting grain before millng.
On the other hand, it might be possible that, avoiding crushing the husks with this procedure, the extraction of tannins from the husks may be improved. Am I thinking right?

Conditioning the grain before milling might improve the flow of the water/wort during mashing, though.

I wouldn't worry about extracting tannins as the temperatures during mashing are too low.

I think this method helps with wheat beers, I've not had a stuck circulation using this method and I don't use rice hulls or anything when using 70% wheat. However I've not tried mashing without malt conditioning either so I couldn't tell you if it makes any difference.

Wheat beers aside, what it should do is filter fine particles more efficiently so that your wort will be very clear - again I can't say because I always use this method and have no comparison.

Again,
Thanks a lot for the posts :D
I've already read Braukaiser: do you suggest 100mL water per 5Kg of grain? Spray bottle?

Do you guys think that the pre-crushing roller on a 3-roller mill would achieve the same effect as wetting the grain on a 2-roller?

It is told to do so.

But the sprary bottle is much cheaper than 3-roller mill :D

Fair enough :cheers:

However, I live in a climate with an average 80%+ humidity and temperature ranges between 27C - 33C - that's year-round by the way :!:

I wonder if wet milling would be putting additional corrosive pressure on the mill.. :roll:

That said - Monster Mill guys also make rollers from 303 steel, which is supposed to be as strong as 1144, but much more corrosion-resistant.

(Still scratching my head over which mill to buy).

Decisions, decisions... :beer:

Well, if I was buying a mill now, I'd go for 3D (BTW, you need much more powerful drill with more torque to run 3D)

But as I have 2D now, I'll not bother with replacing it with 3D as it works fine.
