The most delicious mushrooms are the ones you cook within 180 seconds of picking.
We learned this from a farmer in Anhui who wouldn't let us leave with his shiitake. "Cook these now — don't wait." We did. The umami was something else — deep, almost meaty, with the clean sweetness of pine forests. Nothing like the supermarket.
We spent five years building a chamber that lets you recreate that moment at home, on your kitchen counter. No supply chain. No four-day-old fungi. No compromise.

From the shiitake that anchors miso to the lion's mane that takes the place of crab cakes — six culinary mushrooms, calibrated separately, harvested on your schedule.
Shiitake
Deep umami, the original. For stir-fries, broths, and the family that takes dinner seriously.
Golden Oyster
Bright, floral, almost citrusy. The Sunday-morning scramble mushroom.
Oyster
The weeknight default. Mild, buttery, ready for anything in your fridge.
Lion's Mane
Crispy sear, crab-like texture. The wellness crowd can't stop talking about it.
King Oyster
Meaty stems, scallop-like when seared. For the dish you've been meaning to cook.
Maitake
Hen-of-the-woods. Roasted whole, finished with soy and butter. Worth the wait.
Seven days, then dinner.
Grown on logs engineered with Seven-Rivers Biotech.
