Spent beer grains in substrate?

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.

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?

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

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. RR

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,

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.

Would the nature of an "icing layer" be worth consideration if one were to mix it with coir for a substrate? I have heard that icing layers are bad (ie. exposed grains that are prone to contamination).
That said I bet it will work just fine if you don't use too much.

I think, the nature of a "frosting layer" is NEVER worth consideration. Exposed grains being more prone to contamination is only HALF of the story.
What makes frosting layers/exposed grains more prone to contamination is the fact that exposed grains tend to dry up. When grains dry up, they can no longer become colonized by mushroom mycelium and the myce. stalls, creating a nutrient-rich, breeding ground for invader spores. These spores then gain a foot-holding onto the dried grains before the mycelium'll have a chance to recover, causing infection.
Edit to Add~ OP, concerning your question about what ratio to add the spent beer grains to your sub., I think I would begin experimentation by adding the spent beer grains at roughly 3% by volume of hydrated and pasteurized substrate materials.

I know for a fact that spent grains used for brewing can be used as a substrate additive. I live in an area with a farmers market and i was talking to the local mushroom guy and he says he uses spent grains from a local microbrewing company. Not exactly sure of his ratios or anything but seems like a good experiment.

I just did a search on this subject wondering if I would find anything and here we are the last post only 11 hours ago..
I just noticed this ad from a brewery near me:
"400-500 KILOS OF SPENT GRAIN IS PRODUCED AT THIS MICROBREWERY EVERY WEEK AND IS FREE TO WHOEVER CAN USE IT! Spent grain contains roughly 20 percent crude protein and 50 percent dietary fiber, and makes great feed for cattle, pigs, chickens, goats and horses! It's also great for mushroom farming!"
Being a home brewer myself, I hit up the search for some more info.
Is anyone making practical use out of this material?

My brewer has many 50 lb (dry) spent grain sacks out every day. I would imagine them to be about 85 lbs after they are discarded. I have thrown them in my garden compost pile but may reconsider to try new things. This sounds interesting.

I walked by my local brewery and could smell the 45 gallon barrels of spent grain and thought the same thing. Any one tried it?

I'm trying out some king oyster and lions mane on some spent grain from a stout homebrew this weekend.
My mix is 40 grain, 30 sawdust, 20 popcorn, 8 cardboard, 2 lime.
I tried a 80 sawdust and 20 grain mix with lions mane and maitake a week ago and it is definitely colonizing the grain before the sawdust so I will gradually adjust my mix over the next months to find the sweet spot of grain to other woody ingredients.
I've got a local microbrewery that will be supplying 15 gallons of spent grain every couple weeks and with my homebrew efforts I should have plenty of grain to experiment with. Blue oysters should love the grain, can't wait to try that as well!

There are quite a few breweries in my location... Might have to go inquire about these spent grains. Anything to improve my grows.

Spent grains are usable as a supplement to substrates though I have not tried this myself.

Hi,
So, I am a complete noob to mycology but have more than 10 years experience in zymergy (brewing beer)...
I found this: http://plantchicago.org/2017/01/24/spent-grains-mushroom-growing
Posted in Jan this year...
The important bits are "... process in brewing strips the grain of its sugars, it is still high in proteins and cellulose. This makes it an appealing growing medium for fungi, as they feed primarily on cellulose. While the overall nutrient content depends on the type of grain used, there typically is enough to fuel fungi"
"They performed an experiment to see how well spent grain from Whiner Beer Co. could be incorporated into the mushroom growing process. They inoculated the spent grain with Pleurotus djamor (commonly known as the pink oyster mushroom), and waited for the results."
"To their surprise, they found that the mycelia (the rooting structure of a mushroom) colonized the spent grain in 5 days, compared to 10-15 days for the more traditionally used rye berries. That’s 2-3 times faster!"
And from the Journal of Cereal Science 43 (2006) 1–14 in 2004: "BSG has been successfully used as substrate for cultivation of species of Pleurotus, Agrocybe and Lentinus (Schildbach et al., 1992). BSG had a good biological efficiency and high nutritional value as a substrate for Pleurotus ostreatus, especially when water-rinsed BSG was used (Wang et al., 2001). It has been proposed that BSG favours the growth of these mushrooms not only due to its high protein content (Townsley, 1979) but also to its high moisture content and physical properties such as particle size, volume weight, specific density, porosity and waterholding capacity"
For this forum I feel the following applies; 1) No matter where you got the spent grains or how 'fresh' they are, they have to be processed like any other raw substrate material. 2) If the mycelia really do grow that much faster then the advantage at this stage is the same as for any other organism. Populating the resources before anyone else thereby starving them out... Simply put lower contamination rates. 3) From the smell of spent grains 24-46 hours after brewing, there is alot of surviving microbes. This does many things, influence the pH, improve the levels of some nutrients and decrease the level of others. Most importantly, I feel, if it feels slimy dump it.
Hope that helps answer what appears to be a previously unanswered question.
S
