Description
Beech Mushroom (Hypsizygus tessellatus) Grain Master
For sale is a 1-quart jar of Beech Mushroom Spawn. This is a generation 1 grain master mushroom spawn jar used for expansion of isolate mycelium, optimized for spawn run times and bio efficiency.
Out Grow has isolated this Beech culture for even bottle-form fruiting and the firm crisp texture that makes shimeji worth growing. It is selected for uniformity rather than speed.
What a G1 Grain Master Is
A grain master is a jar of fully colonized grain made to be transferred, not consumed. Generation 1 means the mycelium in this jar came directly from one of our agar plates rather than from another bag of grain, so it sits one step from the culture library instead of three or four. That matters because every transfer is another opportunity for contamination to ride along, and because a G1 jar still has the full expansion runway ahead of it. One quart can seed several more quarts of sterile grain, and those can seed your bulk substrate.
How to Use This Jar
Rest, break, recover, transfer. Beech is a slow deliberate coloniser and you should not mistake that for a problem. Spawn to sterilized supplemented hardwood sawdust and give it the time it needs.
Beech Growing Conditions
Beech colonizes grain in 20 to 30 days at 70 to 75F and fruits at 55 to 65F, with a deliberate cold shock before pinning to bring the clusters in evenly. It is traditionally top fruited from bottles or bags. The longer colonization is characteristic of the species and the resulting mushroom is worth the schedule: firm, crisp, and holding its texture through any cooking method you apply. Sterilized supplemented hardwood sawdust is the substrate of choice.
| Spawn run | 70 to 75F |
|---|---|
| Grain colonization | 20 to 30 days |
| Fruiting temperature | 55 to 65F |
| Substrates | Supplemented hardwood sawdust, Master's Mix |
| Difficulty | Intermediate |
| Season | Cool season |
| Note | Benefits from a cold shock before pinning. Must be cooked |
Storage and Shelf Life
Refrigerate at 35 to 40F. Warm to room temperature for a day before transferring. Do not freeze.
In the Kitchen
Never eat it raw, the flavour is bitter and unpleasant until heat hits it. Cooked it turns sweet and nutty with a crisp bite that holds up in stir fry, soup and roasting.
Guarantee and Live Shipping
Every jar is inspected before it leaves our lab and guaranteed to arrive alive and contamination free. If it does not, photograph the jar sealed and unopened and contact us within 48 hours of delivery for a replacement or refund. Live spawn is temperature sensitive, so we hold shipments during extreme heat and cold rather than sending something that will not survive the trip.
