Golden Chestnut Liquid Culture – 10 ml Sterile Syringe
Species: Pholiota aurivella | Prepared in the UK
Golden Chestnut forms radiant, honey-amber caps with fine, cinnamon flecking. Young mushrooms have a sweet-nutty bite and a satisfying crunch—well suited to cool-season blocks and autumn market mixes.
About This Culture
This 10 ml syringe contains actively growing Golden Chestnut mycelium suspended in nutrient broth, prepared under a sterile workflow. Use it to inoculate grain jars or bags, transfer to agar, or expand into fresh liquid culture in clean conditions.
Included
- 1 × 10 ml Golden Chestnut liquid culture syringe
- 1 × sterile needle
- 1 × alcohol wipe
- 1 × natural hemp bag (outer packaging)
Reusable Hemp Bag
The syringe and wipe ship inside an undyed hemp bag. After pasteurising, you can fill the bag with a substrate of your choice (e.g., coffee grounds mixed with sawdust) to create a small, plastic-free gift grow kit for a friend or classroom project.
Use
- Shake to disperse mycelium.
- Clean the injection point (grain bag port or jar lid) with the alcohol wipe.
- Attach sterile needle; flame-sterilise if working outside filtered air.
- Inject 1–2 ml per grain jar or ~3–5 ml per 1 kg grain bag (adjust to your workflow).
- Incubate grain at 20–24 °C until colonised (≈14–18 days); shake once at ~40 % if desired.
- Spawn to supplemented hardwood sawdust (e.g., ~60 % sawdust : 20 % wheat bran : 20 % millet) at 10–15 % spawn rate.
- Fruit blocks at 12–18 °C with high humidity and steady fresh-air exchange. Harvest caps while slightly domed for best texture.
Storage
Store refrigerated at 2–6 °C. Best within 2–3 weeks; typically usable up to ~2 months unopened. Do not freeze.
Batch Notes
- Produced in small lots; visually checked on agar before dispatch.
- Light sediment is normal—shake before use.
- Optionally place a drop to agar to confirm purity before larger inoculations.
Why Golden Chestnut Supports Local Food Systems
- Performs on supplemented sawdust blends, helping turn local wood by-products into fresh food.
- Cool-weather fruiting extends the season for regional growers and short supply chains.
- Compact clusters travel well from nearby farms to shops and veg-box schemes, reducing food miles.
Lead-time: Made in small batches. We keep limited stock of popular species; if marked back-order please check current lead-time information before ordering.
