    Our Wine Cap is a first-generation Stropharia rugosoannulata isolate, the King Stropharia or garden giant. Colonize grain indoors, mix it into a shaded bed of hardwood chips or straw, and it fruits outdoors with almost no upkeep, often for several seasons.

    Why grow our Wine Cap culture

    Mushrooms in the yard

    No monotub, humidifier or air exchange to manage. A damp, shaded bed and the weather do the work.

    Builds your soil

    The mycelium turns wood chips into rich soil, so beds double as mulch around vegetables and fruit trees.

    Big, meaty caps

    Firm burgundy caps with a mild, earthy flavor. Grill thick slices or sauté young buttons in butter.

    Inoculating with liquid culture

    1Warm and shake

    Let the syringe reach room temperature, then shake it gently to break up and spread the mycelium through the broth.

    2Sterilize

    Flame the needle until it glows, let it cool a few seconds, and wipe the injection port with the included alcohol pad.

    3Inject

    Use 2–3cc per quart jar or 3–5cc per 3–5 lb grain bag. One 10cc syringe inoculates about 2–4 containers.

    4Incubate

    Keep it at 68–80°F in the dark. Shake once at about 30% colonization to speed things up.

    Keep the bed damp, not soaked: water a new Wine Cap bed like you would a vegetable garden. Shade and steady moisture matter more than anything else outdoors.

    Frequently asked questions

    How much liquid culture do I use per jar or bag?

    Use 2–3cc per quart grain jar and 3–5cc per 3–5 lb spawn bag. One 10cc Wine Cap syringe inoculates roughly two to four containers. Using more doesn't speed colonization much; it just uses up the syringe.

    How long does Wine Cap take to colonize grain?

    About 16 days at 68–80°F. After spawning outdoors, a bed typically fruits 14–30 days later, depending on substrate and weather, and established beds keep producing for several seasons.

    What's the best substrate for Wine Cap?

    Fresh hardwood chips, mulch or straw in a shaded outdoor bed. Mix in colonized grain spawn, cover lightly and keep it damp. It grows wild on wood chips across North America in summer and fall.

    Can I plant Wine Cap in my vegetable garden?

    Yes, and many growers do. Run a wood chip or straw bed between rows or around fruit trees. The mycelium breaks the mulch down into soil while you harvest mushrooms from it.

    How should I store the syringe?

    Refrigerate it at 35–45°F in the bag it shipped in and never freeze it; freezing ruptures the cells and kills the culture. Bring it to room temperature and shake gently before you inject.

    Why liquid culture instead of a spore syringe?

    Liquid culture is living mycelium from an isolated culture, so it skips germination, colonizes days faster and gives genetically consistent fruits. Spores have to germinate and pair up first, which is slower and more variable from grow to grow.

    Packed to arrive alive

    Liquid culture is living mycelium, so every syringe leaves our lab in a foil-lined insulated mailer. The insulation buffers it against summer heat in a delivery truck and against sub-freezing winter temperatures, so it arrives viable either way.

    When it arrives: refrigerate the syringe at 35–45°F until you're ready to inoculate. Never freeze it. Bring it to room temperature and shake gently before use.
