How We Make Mushroom Spawn

Pure Genetics, Consistent Spawn

Three million bags a year. 60+ countries. 6 continents.

Every bag starts with pure culture, stored in liquid nitrogen. Made in our own US facilities. Tested in our own lab. Trialed on real commercial farms before it ships. Nothing leaves without passing.

What Makes Amycel Spawn Different

How does Amycel ensure spawn quality?

Every stage uses modern sterile production methods. Every raw material is tested.

Every strain is verified through DNA sequencing and genetic testing. Every product is commercial-proven.

Every bag can be traced back to the strain’s mother culture, maintained in liquid nitrogen for decades for genetic stability.

32 dedicated test rooms

Genetic stability guaranteed

Testing at commercial scale

Our Process

How is commercial mushroom spawn made?

  1. Raw material quality controls

    Every raw material, pure mushroom cultures, and substrate is tested against the industry’s highest standards.

  2. Substrate preparation

    Substrates are cooked and sterilized for contaminant-free spawn.

  3. Inoculation

    Pure mushroom culture comes out of liquid nitrogen storage, gets introduced into sterilized substrate, and bagged for production.

  4. Incubation

    Bagged spawn is carefully stored, fully colonized, and cooled.

  5. Inspection and testing

    Randomized contaminant testing and visual inspection of every bag before packing and shipping.

Spawn Carrier Options

Every strain is available on three substrate options plus PAC, our premium casing spawn.

Millet is the traditional grain carrier. Exxpress is our full-synthetic, grain-free option. Onyxx is a hybrid combining synthetic speed with grain nutrition. PAC promotes even pinning and works with all Amycel strains.
