Mushroom cultivation has piqued the curiosity of many health enthusiasts and home growers alike, especially those interested in the superfood Lion's Mane. This mushroom has taken the wellness world by storm due to its cognitive and mental health benefits. But the question is, will Lion's Mane mushrooms grow on coffee grounds? In this article, we will explore this intriguing question and provide you with comprehensive insights into the cultivation process for Lion's Mane mushrooms on this unconventional medium, which is coffee grounds.
Why Cultivate Lion's Mane Mushrooms?
Lion's Mane mushrooms, scientifically known as Hericium erinaceus, are a popular choice for mushroom cultivation due to their numerous health benefits such as:
- Enhancing cognitive function and memory
- Supporting nerve regeneration
- Boosting the immune system
- Reducing inflammation
- Improve mood and alleviate anxiety and depression
Moreover, Lion's Mane has a unique flavor profile, often described as seafood-like, similar to crab or lobster, making it a desirable ingredient in various dishes.
Why Use Coffee Grounds?
Coffee grounds are an organic waste material that is often discarded. However, they can be a valuable resource for mushroom cultivation for several reasons:
- Environmentally friendly: Repurposing coffee grounds helps in reducing waste and promoting sustainability.
- Nutrient-rich: Coffee grounds contain essential nutrients and minerals like nitrogen, phosphorus, and potassium which are beneficial for mushroom growth.
- Low-cost: Coffee grounds can be obtained for free or at a low cost from local coffee shops or even from your own kitchen.
- Antibacterial properties: Coffee grounds have innate antibacterial properties, which can hinder the growth of unwanted bacteria in the mushroom cultivation process.

Step 1: Preparation of Coffee Grounds
First, collect fresh, used coffee grounds, preferably from a drip coffee maker or espresso machine, and ensure there is no added sugar or milk. Spread out the coffee grounds on a clean surface and allow them to dry for at least 24 hours. This is essential as excess moisture in the coffee grounds can lead to contamination.
Step 2: Sterilization
Sterilize the coffee grounds by pasteurization. Place the dried coffee grounds in a pot of water at approximately 160°F (71°C) and hold that temperature for 1-2 hours. Drain the coffee grounds and let them cool before proceeding to the next step.
Step 3: Inoculation
Inoculate the sterilized coffee grounds with Lion's Mane mushroom spawn. You can purchase spawn from a reputable supplier or make it from a previously grown Lion's Mane mushroom. Evenly mix the spawn with the coffee grounds at a 10-20% ratio (spawn to coffee grounds).
Step 4: Incubation
Place the inoculated coffee ground mixture into a breathable container or grow bag and seal it. Store it in a dark, well-ventilated area with a temperature of around 65-75°F (18-24°C). The spawn will colonize the coffee grounds within two to three weeks, turning it white.
Step 5: Fruiting
Once fully colonized, move the container to an area with indirect sunlight and ambient humidity levels of 80-90%. Ensure that the substrate remains moist but not soggy. Within a week or so, small Lion's Mane fruiting bodies will begin to develop.
Step 6: Harvesting
Harvest the mature Lion's Mane mushrooms, typically when the spines are 0.5-1 inch long. You can expect harvests several times every few weeks until the substrate is exhausted.
Will Lion's Mane Mushroom Grow On Coffee Grounds Example:
Sam decided to try growing Lion's Mane mushrooms on coffee grounds. He collected fresh coffee grounds from his favorite café and dried them for a day. He then pasteurized, inoculated, and incubated the coffee grounds with Lion's Mane mushroom spawn. After a few weeks, the coffee grounds were fully colonized, and he moved them to a spot with indirect sunlight. Soon enough, tiny Lion's Mane fruiting bodies emerged, and eventually, Sam harvested his first batch of delicious, nutritious, home-grown Lion's Mane mushrooms.
In conclusion, Lion's Mane mushrooms will indeed grow on coffee grounds! Not only does this method promote sustainability, but it also offers a cost-effective option for home growers.
