Maitake (Hen of the Woods) Liquid Culture Syringe (10cc)

About Maitake

Maitake (Grifola frondosa), known as Hen of the Woods, is a wild-foraged legend that produces cascading clusters of grey-brown fronds resembling the feathers of a fluffed hen. Found at the base of mature oaks in autumn, this mushroom is one of the most prized culinary and functional species in both Japanese and North American traditions — deeply earthy, nutty, and rich, with researched properties supporting immune function and metabolic health. Growing it is a rite of passage for serious cultivators, and a successful Maitake block is one of the most rewarding harvests in mycology.

Growing Notes

• Difficulty: Advanced
• Preferred substrate: Supplemented hardwood sawdust (oak preferred); also cultivated on oak logs
• Fruiting temperature: 55–65°F
• Colonization speed: Slow
• Special considerations: Maitake forms a dense sclerotium-like mass before fruiting — be patient, as full colonization and maturation can take 8–12 weeks. Cold-shocking the colonized block helps initiate fruiting. Requires careful humidity management to prevent the frond tips from drying out.

Culinary Uses

Maitake has a deeply earthy, nutty, and peppery flavor with a satisfying texture — the frond tips crisp up beautifully when roasted or pan-fried while the base stays tender and succulent. Roast whole clusters with olive oil and sea salt, sear in butter, or pull apart for risottos and grain bowls. Pairs exceptionally well with fall squash, wild game, and robust red wines. One of the most sought-after wild mushrooms at gourmet markets.

Functional Benefits

Maitake is rich in beta-glucans, particularly the D-fraction fraction studied for immune-modulating activity. Research has also explored maitake for potential support of blood sugar regulation and metabolic health. Traditionally used in Japanese and Chinese medicine as a tonic for vitality and immune support.

Usage Instructions

• Sanitize your work area, tools, and contact surfaces before handling.
• Prepare grain, substrate, agar, or grow kits according to your standard operating procedures.
• Introduce the liquid culture using sterile or near-sterile technique (e.g., in front of a flow hood or still-air box when applicable).
• Maintain species-appropriate incubation and fruiting conditions for temperature, humidity, and fresh air exchange.

Shelf Life & Storage

Store refrigerated at 34–39°F (1–4°C) away from direct sunlight. Under proper storage, typical shelf life is 3–6 months unopened. Always visually inspect for contamination, damage, or off-odors before use.

Quality & COA

Each batch is prepared using standardized procedures and test-inoculated on appropriate media before release. These internal checks act as our in-house Certificate of Analysis (COA) to confirm viability and cleanliness at the time of packaging.

How to Use This Liquid Culture

1. Sterilize the injection port on your grain bag with an alcohol prep pad.
2. Shake the syringe vigorously for 10-15 seconds to disperse the mycelium evenly.
3. Inject 1-2cc of liquid culture through the self-healing injection port of your grain bag. Less is more — 1cc is usually plenty.
4. Seal and incubate the bag at 70-75°F in a clean, dark space.
5. Wait for colonization — white mycelium will begin spreading through the grain within 2-4 weeks.

Temperature & Timeline: Colonization typically takes 2-4 weeks at 70-75°F. Warmer is not better — temperatures above 80°F increase contamination risk.

Signs of Success: You'll see white, fluffy mycelium spreading outward from injection points. The grain will become covered in a uniform white coating when fully colonized.

Next Steps: Once the grain is fully colonized, transfer it to a bulk substrate or introduce fruiting conditions, depending on your setup.

Common Mistake: Injecting too much liquid culture does not speed up colonization — it wastes culture and can introduce excess moisture that encourages contamination. Stick to 1-2cc per bag.
