Was headed out camping and walked by my coffee grounds bucket, and was shocked by what I saw!
This what the project looked like in April.
I had been around this area earlier in the week and didn’t notice anything!
Beautiful luxurious Oyster Mushrooms! They are growing quite well, and I can’t wait to eat them. This marks a growing success for me, because this was the Oyster growing project I was most interested in.
Tons and tons of coffee grounds are wasted in our landfills each year. This proves that food can be produced using this waste product. Not only does it keep this valuable resource out of our landfills, but the mushrooms also neutralize the caffeine in the grounds.
Once again the process was low cost and not labor intensive. The spawn was just simply mixed into the coffee grounds and left to grow on it’s own. I can see a real use for these mushrooms in poor countries with shortages of food, and plenty of waste.
Thanks again to Wild Joe’s for the organic coffee grounds, and Garden City Fungi for the spawn.
This is the best use of a waste product I have ever seen. Especially when there is plenty of coffee ground waste in America . Wonderful invention can go a long way contributing to malnutrition. Thank You
Thank you, and yes I agree! I could not stand for organic coffee grounds to be thrown away. The next step will be to grow reishi and shiitake on the coffee grounds. An added bonus is the mushrooms eat the caffeine and keep it out of our water.

Hi,
Pls email instructions on how to prepare coffee grounds before adding spawn or liquid culture to coffee grounds.
Thankyou
Hello,
Thank you for your response!
Coffee grounds don’t need any preparation for inoculation. Fresh out of the coffee maker, they are moist and pasteurized. When they come to room temperature, you can add the spawn. It gets trickier when they mold, which they do very quickly. Since they are pasteurized, they are a perfect environment for mold, as well as spawn. I have inoculated moldy coffee grounds, and they flushed with oyster mushrooms. Oyster spawn is very aggressive and it overtook the mold. Otherwise you would have to pasteurize or sterilize the coffee grounds. This would be way to expensive and messy for production. One way to keep your coffee grounds from getting moldy is to keep them frozen until you are ready to inoculate. There is quite a bit about oysters growing on coffee grounds on the site under oysters or coffee grounds. Let us know how you do,
Dean
