Beech Woodchips Substrate | 10 L Bag

Beech is the hardwood of choice for cultivating wood-loving gourmet mushrooms. Our 10 L bag of cleanly screened beech woodchips gives you a uniform, low-residue substrate ready for hot-water pasteurisation or supplemented sterilisation.

Product specifications

• Net volume: 10 L bag
• Chip size: ~3 mm screened — uniform pieces for even colonisation
• Species: pure European beech (Fagus sylvatica), no fillers
• Treatment: untreated, kiln-dried, free of resins and tannins
• Use: bulk substrate for wood-loving fungi after pasteurisation or supplemented sterilisation

Which mushrooms grow on beech woodchips

Beech is the textbook substrate for wood-loving gourmet and functional species. From our own catalogue, beech woodchips are the matching bulk substrate for our two functional Liquid Cultures:

• Lion's Mane Liquid Culture — Hericium erinaceus, the textbook beech-loving gourmet
• Reishi Liquid Culture — Ganoderma lingzhi, hardwood-grown functional mushroom

For advanced wood-loving Psilocybe experiments, beech chips also support Psilocybe zapotecorum 'Popocatépetl Volcano' Liquid Culture — a wood- and loam-loving Psilocybe from the Mexican highlands (warm, advanced cultivation).

Beech is also the classic substrate for these gourmet wood-lovers (not currently in our LC range):

• Lentinula edodes — shiitake
• Pleurotus ostreatus — oyster mushroom (with added straw)
• Flammulina velutipes — enoki

For manure-loving species like Psilocybe cubensis and Psilocybe natalensis, use a coir-based mix instead: Sterile CVG Substrate Mix .

How to prepare beech woodchips

1. Hydrate — soak chips in clean water for 12–24 hours until fully saturated
2. Drain — let excess water drain off to "field capacity"
3. Pasteurise — heat to 65–82 °C for 1–2 hours (hot-water bath or oven), or supplement with bran and pressure-sterilise at 121 °C / 15 PSI for 90–120 minutes
4. Cool — drop the substrate to 24–27 °C before inoculation
5. Inoculate — combine with fully colonised grain spawn at 1:5 to 1:10 by weight
6. Incubate — keep at 22–26 °C in the dark until fully colonised (3–8 weeks depending on species)
7. Fruit — induce pinning with cooler temperatures, light and fresh air

Pasteurise or sterilise?

Plain unsupplemented beech chips can be pasteurised (65–82 °C for 1–2 hours) — the low nutrient profile keeps contamination risk manageable. If you supplement the chips with wheat bran, soy hulls or grain to boost yields, switch to pressure sterilisation (121 °C / 15 PSI / 90–120 min) because the added nutrients invite competing moulds.

Pair with grain spawn

Beech woodchips colonise reliably when paired with vigorous grain spawn: Sterile Sorghum Spawn Bag is a strong match for hardwoods. For oyster on a straw-chip mix, see our wheat straw substrate.

Storage

Keep the unopened bag in a cool, dry place, away from direct sunlight. The chips have a shelf life of 12+ months when stored dry.
