Tutorials/Harvest/Drying and Storage
Fresh mushrooms are mostly water, around 90%, and start breaking down within days. Drying them properly lets you keep a harvest for a year or more. Colorado's dry air is a real advantage here.
Fresh storage
If you'll use them within a few days:
- Don't wash them. Brush off any substrate.
- Store them in a paper bag in the fridge. Plastic traps moisture and turns them slimy.
- Most keep about 5–7 days this way.
Drying
The goal is cracker dry: a stem should snap cleanly with an audible crack, not bend. Anything less than cracker dry can mold in storage.
Food dehydrator (most reliable)
- Clean off substrate and trim any dirty stem bases.
- Cut large mushrooms in half lengthwise so they dry evenly.
- Spread them on the trays in a single layer, not touching.
- Dry on a low setting, roughly 95–120°F. High heat dries faster but can cook them and darken the color.
- Most batches take 6–24 hours, depending on size. Check by snapping the thickest stem.
Fan and air drying
Indoor air in Colorado is often 10–25% humidity, which is dry enough to air-dry mushrooms without heat.
- Lay the mushrooms on a wire rack or screen so air reaches every side.
- Point a fan at them. Moving air is what does the work.
- Expect them to reach a leathery stage in a day or two. This is usually not fully dry; finish them in a dehydrator or with desiccant (below).
Desiccant finish
For a guaranteed dry, seal fan-dried or dehydrator-dried mushrooms in an airtight container with a few silica gel packets for a day or two. The silica pulls out the last of the moisture.
Long-term storage
- Airtight containers: mason jars or vacuum-sealed bags.
- Add a desiccant packet (food-safe silica gel) to each container.
- Store them cool, dark, and dry. Light and heat degrade dried mushrooms over time.
- Label each container with the strain and harvest date.
- Check jars occasionally for the first few weeks. Any softness, condensation, or musty smell means they weren't fully dry; re-dry them right away.
Dried properly and stored this way, mushrooms keep well for a year or more.
Rehydrating
Soak dried mushrooms in warm water for 20–30 minutes. Keep the soaking liquid; it carries a lot of flavor for cooking.
