Mushrooms are biologically distinct from plant- and animal-derived foods, including fruits, vegetables, grains, dairy, legumes, nuts, and seeds. However, grain spawn, also known as mushroom spawn, is an essential ingredient in mushroom cultivation. It is a mixture of sterilized grains, such as rye or wheat, that have been inoculated with mushroom mycelium. This mycelium forms a network of fungal cells that colonize the grains, resulting in a highly concentrated source of mushroom spores. This process of making grain spawn is almost identical for growing different kinds of mushrooms.

What You'll Learn
Mushrooms are not grains, they are fungi
The process of creating grain spawn is essential for anyone cultivating mushrooms. It involves selecting the right grain, sterilising it, inoculating it with mycelium, incubating it, and then transitioning it to the fruiting stage, where mushrooms begin to grow. The grain spawn provides the necessary nutrients and support for the mycelium to flourish and produce mushrooms.
Mushroom cultivation is a delicate and intricate process that requires careful attention to detail, especially during sterilisation. The grain must be completely sterilised to eliminate any potential contaminants and ensure a clean environment for the mycelium to colonise. This is typically done using a pressure cooker or autoclave, which kills off any mould spores or bacteria that could compete with the mycelium.
While mushrooms are not grains, they are often grown using grains as a substrate. This is because grains provide a nutritious food source for the mushroom mycelium, which needs starch and sugars to grow. Additionally, grains have the right moisture content and provide a large number of "inoculation points" for the mycelium to spread.
In summary, mushrooms are not grains but are instead a type of fungi. Grain spawn, made from sterilised and inoculated grains, plays a crucial role in mushroom cultivation by providing the necessary nutrients and environment for mushrooms to grow and thrive.

Grains are used to grow mushrooms
Mushrooms are not grains, but grains are used to grow them. Grain spawn is a traditional way to propagate mushroom cultures. It is a substrate created by sterilizing grains and introducing mushroom spores or mycelium. The mycelium will continue to grow and eventually produce mushrooms.
Grains are highly nutritious and full of starch and sugars. When properly hydrated, they serve as an ideal food source for mushroom mycelium. However, this environment is also ideal for the growth of mould and bacteria, which can grow much faster and stronger than mushroom mycelium. Therefore, grains must be completely sterilized before use, usually in a pressure cooker or autoclave.
There are many types of grains that can be used for grain spawn, including wheat, rye, brown rice, white rice, wild bird seed, millet, and even popcorn. The most common grain used for mushroom cultivation is rye, due to its water-absorbing qualities, nutrient composition, and the fact that mushrooms seem to thrive on it. Smaller grains like millet are also preferred for their higher number of inoculation points. Other grains, such as wheat berries, sorghum, barley, and brown rice, can also be used, although they may not perform as well as rye.
Grain spawn is crucial for achieving consistent and uniform mushroom crops, making it indispensable in commercial mushroom production. It provides a reliable source of mycelium, contributing to the even growth and development of mushrooms. By using grain spawn, growers can achieve consistent colonization and fruiting, resulting in a greater yield and superior quality of mushrooms.

Popular grains for growing mushrooms include rye, wheat, and barley
Mushrooms are not grains, but grains are used to grow mushrooms. Popular grains for growing mushrooms include rye, wheat, and barley. Millet, brown rice, white rice, wild bird seed, and even popcorn can also be used as grain spawn for mushroom cultivation. However, rye is the most common grain used for this purpose due to its water-absorbing qualities, nutrient composition, and mushroom growth compatibility.
When preparing rye grain for mushroom cultivation, it is important to start by removing any impurities, such as bugs or dust, and then hydrating and sterilizing the grain. The rye should be soaked in water for 12 to 24 hours and then cooked for 15 to 20 minutes to ensure proper hydration. After cooking, the grains should be drained and allowed to steam dry until they are dry on the outside but still hydrated on the inside.
Wheat berries, or wheat grain/seeds, are another excellent choice for mushroom cultivation and can be prepared using a similar method as rye grain. However, wheat cannot hold as much water and is more prone to breaking during processing. Organic wheat berries can often be found at bulk food stores.
Barley is another cereal grain that can be used for mushroom spawn, although it may not be ideal due to the tendency of the grains to become mushy and wet. Some people have reported success in growing mushrooms with barley by soaking it in diluted coffee before sterilization.
Overall, while mushrooms themselves are not grains, grains play a crucial role in mushroom cultivation by providing a nutritious and hydrating growth medium for the mushroom mycelium to thrive in.

The grains used to grow mushrooms must be sterilized
Mushrooms are not grains, but grains are often used to grow them. The grain spawn is a traditional way to propagate mushroom cultures. It is made from sterilized grains that have been inoculated with a live mycelium culture. The fully colonized grain spawn can be used as a starter culture for growing mushrooms.
Grain spawn contains a lot of energy for the mycelium to consume. It is a bit like rocket fuel for mushrooms. Once it’s added to your substrate, it takes off like wildfire. Mother Nature works her magic using spores, but in a controlled environment, you need to tip the scales in your favour by using clean, high-quality grain spawn to ensure success.
The most common grain used for mushroom cultivation is rye. This is because of its water-absorbing qualities, nutrient makeup, and the fact that mushrooms seem to love it. Other grains used for grain spawn include wheat, brown rice, white rice, wild bird seed, millet, and even popcorn.
To avoid contamination, some mushroom substrate varieties require sterilization. The nutrient level of the substrate is the most crucial aspect in determining whether you need to sterilize it. Manure, for example, should always be sterilized as it is teeming with germs and microbial life. All substrate materials that could be considered food, such as rye grain, popcorn, brown rice, and wheat berries, should also be sterilized as they attract a wide variety of fungus and mould.
Sterilization involves heating a substrate to temperatures above 120°C under pressure to kill any living or dormant contaminants. This can be done in a pressure cooker, which reaches temperatures high enough to destroy bacteria and mould spores.

Mushrooms are nutritious and can contribute to a healthy diet
Mushrooms are a nutritious food that can be incorporated into a healthy diet in various ways. They are a fungus, and only a small fraction of fungi are edible mushrooms. They are low in calories and can be eaten raw or cooked, adding flavour to many recipes without significantly increasing fat, calorie, or sodium content.
Mushrooms are a good source of vitamins, minerals, and antioxidants, which can help prevent several health conditions and improve overall health. For example, they contain vitamin D, which helps with calcium absorption for strong bones and immune function. They are also a source of vitamin B6, which aids in the formation of red blood cells, and selenium, which helps prevent cell damage. Additionally, mushrooms are a rich source of potassium, which can help regulate blood pressure and reduce the negative impact of sodium on the body.
The nutritional profiles of mushrooms vary between types, with some species being toxic to humans. Popular edible mushrooms include cremini, maitake, shiitake, oyster, and king oyster mushrooms. These mushrooms can be added to recipes such as pizza, salads, pasta sauce, or cooked meats.
Mushrooms are also easy to incorporate into a daily diet as they are readily available in grocery stores or health food stores. They can be purchased fresh, canned, or dried, and can be cooked in various ways, such as simmering, sautéing, or sprinkling raw over meals.
In addition to their nutritional benefits, mushrooms are also used in grain spawn, a traditional way to propagate mushroom cultures. Various grains, such as rye, wheat, and millet, are sterilized and inoculated with a live mycelium culture to create grain spawn, which serves as a food source for mushroom mycelium and promotes its growth.
