Process, ferment, dry, or value-add? Apply for Field-Grade pricing.
Stone & Spore supplies bulk-grade specialty mushrooms — same fresh harvest as our chef accounts, sorted for processing utility rather than retail display. Flat Rate across all five varieties: Blue Oyster, King Black Pearl, Chestnut, Lion's Mane, and Same-Day Fancy Oysters.
Approved Field-Grade partners get:
- Wholesale pricing across all five varieties
- "What's in the Bin" weekly surplus availability notifications (your selected cadence)
- Bulk pickup at our Berryville facility
- No retail-display sorting penalty — same fresh harvest, processing-grade tier
- Access to our Mushroom Culinary Guide for handling and storage best practices
Who this is for: butchers, farm stores, catering kitchens, value-add producers (sauces, dried blends, ferments, pâtés), and livestock/animal feed operations.
What to expect: Field-Grade product is structurally sound and harvested fresh, but may include broken stems, asymmetric clusters, or minor cap tearing. It's sorted for processing utility — ideal for kitchens that grind, ferment, dry, or otherwise transform the mushroom rather than plate it intact.
Pickup at the Farm in Berryville is required. Bulk volumes aren't economical to deliver. 5 lb minimum per pickup.
Most applications are reviewed within two business days.
