Are you a coffee lover looking to experiment with new ways to grow your own gourmet mushrooms? Then you have come to the right place! In this blog, we will explore how mushroom spawn can be used in coffee grounds to produce delicious and nutritious mushroom varieties. This sustainable method not only helps in mushroom cultivation but also contributes to the reduction of coffee waste. Get ready to dive into the wonderful world of fungal growth and coffee mash-ups with Mr Mushroom!
Why Use Coffee Grounds for Growing Mushrooms?
Coffee grounds are an excellent substrate for growing mushrooms for several reasons:
- Rich in nutrients: Coffee grounds are packed with essential nutrients such as nitrogen, potassium, and phosphorous, all of which are crucial for healthy mushroom growth.
- Sustainable practice: Using coffee grounds diverts waste from landfills, making it a sustainable and environmentally friendly alternative to other substrates.
- Texture: The fine particles in used coffee grounds create an optimal environment for mycelium colonization and mushroom growth.
- Accessibility: Coffee grounds are readily available from local coffee shops that are usually more than happy to give away their used grounds for free.
Choosing the Right Mushroom Spawn
Not all mushroom varieties are suitable for growing in coffee grounds; it's essential to pick the right mushroom spawn that can thrive in this unique medium. The following are some of the best species for coffee ground cultivation:
- Oyster mushrooms: One of the most popular and easy-to-grow varieties, oyster mushrooms (Pleurotus spp.) thrive in coffee grounds due to their ability to break down complex compounds quickly.
- Lion's mane: A gourmet and medicinal mushroom, lion's mane (Hericium erinaceus) is another great option for growing in a coffee ground substrate. They contain compounds that support cognitive function and digestive health.
- Shiitake: A versatile and delicious mushroom, shiitake (Lentinula edodes) can be grown using coffee grounds mixed with other substrates like hardwood sawdust to achieve optimal growth conditions.
Preparing Your Coffee Grounds
Before introducing your mushroom spawn to coffee grounds, it is necessary to properly prepare the substrate. Follow these steps to get your coffee grounds ready for cultivation:
- Collect used coffee grounds: Visit local cafes and ask for their used coffee grounds. Store them in a sealable container or bag to prevent contamination.
- Pasteurize the coffee grounds: To eliminate any unwanted microorganisms, pasteurize the coffee grounds by heating them in water at 140°F (60°C) for 1-2 hours. Then, drain and cool the grounds to room temperature.
- Adjust moisture content: Aim for a moisture content of around 60% by gently squeezing the grounds until they form a ball that holds its shape. It should not release excess water when pressed.

Assuming you have chosen to grow oyster mushrooms in your coffee grounds, follow this example to set up your mushroom cultivation.
Materials:
- Oyster mushroom spawn
- Pasteurized coffee grounds
- Plastic containers or grow bags
- Scalpel or clean knife
- Spray bottle with water
Instructions:
- Break up the oyster mushroom spawn into small pieces with your hands or a sterilized knife.
- Mix the spawn with pasteurized coffee grounds, ensuring an even distribution throughout the substrate.
- Fill the plastic containers or grow bags with the spawn and coffee ground mixture, leaving some headspace for air exchange.
- Poke small holes in the container lid or bag for gas exchange and cover it with a breathable material like a coffee filter or micropore tape.
- Place the container in a dark, humid, and warm area (60-75°F, or 15-24°C) for 2-3 weeks to allow for mycelium colonization.
- Once the mycelium has colonized the entire substrate, induce fruiting by exposing the container to fresh air, light, and lower temperatures (about 55-65°F, or 13-18°C).
- Maintain humidity levels around 90% by misting the substrate with water daily.
- Harvest the mushrooms once they have reached their mature stage by gently twisting them from the substrate, taking care not to damage the mycelium.
