Our USDA-certified organic chestnut (Pholiota adiposa) grain spawn features a popular strain widely cultivated in Japan. It produces velvety, small-to-medium, delightfully speckled mushrooms with caps resembling the color of their namesake nut. When cooked, they have a woodsy aroma, a meaty heaviness, and a rich, nutty, mildly-sweet flavor.

Chestnuts can be a bit finicky, but generally grow well indoors. They prefer cooler temperatures and are prone to drying out or stopping their growth if humidity is not maintained when the mushrooms are still in their early stages. However, when they grow successfully you can expect significant and commercially-viable harvests. Note that chestnuts do not reliably produce second flushes.

"5 of the Best Chestnut Mushroom Recipes"

Recommended use:

  • Chestnut grain spawn can be used for indoor production using sawdust-based sterile substrate.
  • Do not use grain spawn for log inoculation.
  • This is not a mushroom grow kit. Chestnut grain spawn must be combined with a substrate in order to fruit. 

Upon receiving your spawn:

Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Scroll down for specifications, growing, and storage guides.

  • Weight: Approximately 6 lbs
  • Hydration: Average of 47%
  • Bags: Gusseted 2.2 mil polypropylene
  • Filter: High efficiency .2 micron
  • Inoculation Rates: 6 lb. bag of grain will inoculate between 120-165 lb. sterilized sawdust, and 100-130 lb. pasteurized straw
  • Sterilization method: Commercial grade autoclave sterilized
Fruiting temps 60-70 degrees F
Humidity 88-95%
CO2 Sensitivity <1,000 ppm

 

  • Fruiting - The phase of growth in which visible mushrooms begin to appear.
  • CO2 sensitivity - When CO2 levels are too high, yields will decrease, stems will become long and stringy, caps will be small, and/or growth will halt.

Chestnut mushroom grain spawn can be mixed into sterilized hardwood sawdust to create chestnut substrate blocks.

Note: Grain spawn must be mixed with bulk substrate before you can fruit it. If you are new to growing mushrooms, we recommend purchasing a book on mushroom cultivation.

If you don't plan to use immediately, you can refrigerate your spawn for up to 4 months.

"5 of the Best Chestnut Mushroom Recipes"

For those who enjoy the distinct nutty flavor of chestnut mushrooms, we recommend frying them up with butter and garlic or adding them to your favorite creamy soup or pasta dish. As with other mushrooms, chestnut mushrooms require thorough cooking. However, given their lower moisture content, they do not require “sweating” in the pan.

Our grain spawn is USDA certified organic and made using organic cultures from our own culture bank. It contains a blend of locally sourced, organic, and non-GMO ingredients from farms in New England and North America.

If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.
