White Beech Shimeji Liquid Culture Syringe (10cc)

About White Beech Shimeji

White Beech Shimeji (Hypsizygus tessellatus, white variety) is the pale, elegant sibling of Brown Beech — same species, selected for its creamy white coloration. It produces tight, beautiful clusters of small mushrooms with a crisp texture and a sweet, nutty flavor that's highly sought after in Japanese and Korean cuisine. The pristine white caps make for stunning plate presentation.

Culinary Uses

White Beech Shimeji offers a crisp, satisfying texture and a sweet, lightly nutty flavor that elevates miso soup, ramen, stir-fries, and rice dishes. The firm stems hold their snap even when cooked briefly, making them a favorite for quick sautés and one-pot meals. Their clean white appearance adds visual appeal to any dish. Separate clusters at the base before cooking.

Growing Notes

• Difficulty: Intermediate
• Preferred substrate: Supplemented hardwood sawdust blocks
• Fruiting temperature: 55–65°F (13–18°C)
• Colonization speed: Moderate
• Special considerations: Like the brown variety, White Beech fruits best in cooler conditions with high humidity and a casing layer for even pin formation. Maintain stable temperatures for consistent cluster development. The white coloration is a selected trait — keep fruiting conditions clean to preserve visual quality.

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.
