Description
King Stropharia (Wine Cap) Liquid Culture Syringe (10cc) — Stropharia rugosoannulata, first-generation (G1) isolated genetics from Myco Labs. Wine Cap is the garden mushroom. It is grown in outdoor beds of wood chips and mulch rather than in a chamber, producing broad reddish-brown caps the size of a hand — which is why growers call it the Garden Giant.

Why Growers Choose Wine Cap
Wine Cap is the easiest way to put mushrooms in your yard. You colonize grain spawn indoors, mix it into a bed of hardwood chips or straw somewhere shaded, keep it damp, and let the weather do the rest. No monotub, no humidifier, no fresh air exchange to manage — and once a bed is established it will often fruit for several seasons running.
It also earns its keep in the garden itself. The mycelium breaks down wood chips into rich soil, and growers frequently run Wine Cap beds through vegetable rows and around fruit trees as a mulch system that happens to produce dinner. It appears naturally across North America through summer and fall, so it is well suited to most of the country.
On the plate the caps are firm and substantial with a mild, earthy flavor, and young buttons have a faint potato-like quality. They are excellent grilled in thick slices or sautéed in butter with herbs.
What's In the Package

How to Use Your Liquid Culture Syringe
- Let the syringe come to room temperature, then shake gently to redistribute the mycelium evenly through the broth.
- Flame-sterilize the needle until it glows orange and let it cool for a few seconds.
- Wipe the injection port on your grain spawn bag or jar with the alcohol prep pad.
- Inject 2–3cc per quart jar, or 3–5cc per 3–5 lb spawn bag. One 10cc syringe inoculates roughly 2–4 containers.
- Incubate at 68–80°F in the dark for around sixteen days until the grain is fully colonized.
- Break the spawn into a shaded outdoor bed of hardwood chips, mulch or straw, four to six inches deep. Water it in, keep it damp, and let the season take over.
Frequently Asked Questions
Can you grow Wine Cap indoors?
Yes, but it is genuinely difficult and we would not recommend it as a first project. We have fruited Wine Cap indoors on grain bags and even in monotubs — the photo below is one of our own indoor trays — but it took freezing the colonized substrate and working through a fairly involved process to trigger pinning. Outdoors in a wood-chip bed, the same culture fruits with almost no intervention. If you want a straightforward indoor grow, choose an oyster or Lion's Mane; if you want Wine Cap, give it a garden bed.
How do I start a Wine Cap bed?
Colonize grain spawn indoors first, then choose a shaded spot with good drainage. Lay down four to six inches of hardwood chips, straw or mixed mulch, break the spawn through it in layers, water thoroughly and keep the bed damp. Spring and fall are the best planting windows. Beds under trees or along the shaded side of a garden row work well.
How long until my Wine Cap bed produces?
Fruiting typically begins fourteen to thirty days after conditions are right, but outdoor beds run on the weather rather than a schedule — a bed planted in spring may not produce until late summer or fall. Once established, a healthy bed will often fruit for several seasons, and topping it up with fresh chips each year extends it further.
What does Wine Cap taste like?
Mild and earthy with a firm, substantial texture — closer to a portobello than an oyster. Young buttons carry a faint potato-like note. The caps get large enough to slice thick and grill like a steak, and they hold up well to sautéing with butter and herbs. Always cook them thoroughly.
Can I plant Wine Cap in my vegetable garden?
Yes, and many growers do exactly that. Wine Cap mycelium digests wood chips into soil, so a bed doubles as a mulch layer through vegetable rows or around fruit trees. Keep it shaded and damp, and avoid mixing it into ground you plan to till, since disturbance breaks up the mycelial network.
How much liquid culture do I use per bag or jar?
Use 2–3cc per quart grain jar and 3–5cc per 3–5 lb spawn bag. A single 10cc Wine Cap syringe will inoculate roughly two to four containers, which is enough spawn for a decent starter bed. Adding more than the recommended dose does not speed colonization meaningfully.
How should I store the syringe before use?
Keep it refrigerated between 35 and 45°F and never freeze it — freezing ruptures the cell walls and kills the culture. Store it in the sealed bag it shipped in, away from strong odors. Bring it back to room temperature and shake gently before injecting.
Packed to Arrive Alive
A liquid culture syringe is living mycelium, and the trip from our Illinois lab to your door is the part of its life you have the least control over. That is why every Myco Labs liquid culture ships inside a foil-lined insulated mailer rather than a plain envelope. The insulation buffers the syringe against summer heat sitting in a delivery truck and against sub-freezing temperatures in winter, so your culture arrives viable in either extreme.
When it arrives: move the syringe to the refrigerator at 35–45°F until you are ready to inoculate. Never freeze it. Bring it back to room temperature and shake gently before use.
