Spent beer grains in substrate?
    #14851310 - 07/31/11 12:07 PM (12 years, 7 months ago)

I just brewed 10 gallons of beer and have about 30 pounds of grain has anyone ever pasteurized and added it to substrate?  I was thinking of mixing it with coir because that is what i have.  Ratio?




Ok so here it goes.  2 tubs each with 4 quarts GT.

Tub 1: 1/4/4 verm/coir/spent beer grains
Tub 2: 1/8  verm/coir

spent beer grains


beer grain: the mix is much denser then just the coir/verm

I brew too and would like to know the answer to this also.  Im sure you could if it is properly pasterized just dont know how well it will work

I would love to know. You should really try just colonizing a jar and see how well the mycelium takes to it. :thumbup:

I wouldnt use it for jars.  Id use it pasteurized as part of my sub like the OP was suggesting mixing it with coir.  Just make sure you properly pasteurize it

But is it something that just pasteurization would be enough?

Better than sterilization for sub

Seems as though I read something about these being used for Oyster spawn substrate before. And if you are doing all grain brewing, it seems to me that it should already be pasteurized. I havent brewed in a really long time, but if I remember right theres aan hour long 140-160 degree temperature cycle for sugar conversions. Though that temp may be off, like I said its been a long time.

Edit: Meant substrate.

150F there abouts for an hour you could then just add more water after your pour off and let it sit for another half hour

Did you sparge until the wort ran clear?  If so there's surely not much sugar left in it, maybe as a fluff for the substrate, and I see no reason to have to pasturize it again since you had it at probably 155 degrees and sparge water is usually at 170 degrees.  Just my thought on this as I brew also.

Well i brewed yesterday and just spread the grains on the cement outside to dry because i was not ready to make a tub yet. I will re pasteurize next weekend and let you guys know how it goes. Would still be great to hear form some one who has done it.  I feel like the mushroom growing and beer brewing communities must overlap

My brother brews beer and we were wondering about the grains. I wish you luck.

Hopefully, one of you guys will make a substrate and report back.  The mrs was saying today that we need to start brewing our own, just as I was sending her for the second rack this weekend. :wink:

My next brew out I am going to try also.  Fuck its pretty much already pasterized I personally think the texture is awesome for muxhrooms.  I only just started brewing my first all grain was only a cpl weeks ago but I was thinking that it would be good when I was brewing

This is a great thread.  The fact that the sugars are likely used up makes
this seem like a better sub additive than a spawn grain.

I love the idea.  Hell, I might start brewing too.  ;0)

Good luck,

JD

Re-pasteurize it along with more Barley Malt extract, ("Sugar"), (at what amount/ratio, I dunno). I agree that while they are an excellent additive, they're not a SOLE substrate to spawn to- I have never tried, so I DON"T know... Try a 50/50 of spent grains and coir on half of them and a 50/50 spent grains, (+plus liquid barley malt added), and coir, And see which is better and which is more susceptible to contams. Who knows?

Stamets mentions it as an additive... But no quantity is mentioned (that I recall). I think a comparison might be mentioned in relation to his data charts.
