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

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.

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
