Wine Cap Mushroom (Stropharia rugosoannulata) Grain Master
For sale is a 1-quart jar of Wine Cap 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 Wine Cap culture, also sold as King Stropharia, for aggressive bed colonization and large burgundy caps.
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. Wine Cap is an outdoor bed species and this jar is best used either to expand into more grain, or to inoculate a hardwood chip or straw bed directly. Spread it through the bed material rather than layering it on top.
Wine Cap Growing Conditions
Wine Cap, also sold as King Stropharia, is one of the most productive outdoor mushrooms you can grow. Build a bed of hardwood chips or straw in a shaded spot, work the spawn through the material rather than layering it on top, keep it damp, and it will produce for several seasons while improving the soil underneath. Grain colonizes in two to four weeks at 70 to 81F and beds fruit at 50 to 70F. Indoor fruiting is possible with a pasteurized casing layer, though the outdoor bed is where this species genuinely excels. Caps run burgundy red and can reach dinner plate size in a well established bed.
| Spawn run | 70 to 81F |
|---|---|
| Grain colonization | 2 to 4 weeks |
| Fruiting temperature | 50 to 70F outdoors |
| Substrates | Hardwood wood chips, straw, chip and straw beds |
| Difficulty | Beginner outdoors |
| Season | Outdoor, spring through autumn |
| Also known as | King Stropharia |
| Note | Outdoor wood chip or straw bed cultivation |
Storage and Shelf Life
Refrigerate at 35 to 40F. Warm to room temperature for a day before transferring. Do not freeze.
In the Kitchen
Large firm caps with a texture closer to a portobello than an oyster. The stems are tough and best discarded. Excellent grilled or roasted whole.
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.
