Also known as the "Garden Giant," Wine Cap (Stropharia rugoso-annulata) is a delicious mushroom with a mild, earthy flavor reminiscent of artichokes and potatoes. It's an ideal mushroom for beginners as it colonizes quickly and yields reliable flushes.
Wine Cap can fruit in as little as two months and will produce in the same bed for several years. Fresh woody material (like hardwood chips) can be added each year to maintain the health of the bed. Inoculated material from one bed can also be used as spawn to inoculate new beds!
Recommended use:
- Wine cap sawdust spawn is only recommended for use in outdoor beds or top-fruiting containers.
- This is not a mushroom grow kit. Wine cap sawdust spawn must be combined with a substrate (like wood chips) in order to fruit.
- Please note: Wine cap does not grow on logs.
Upon receiving your spawn:
Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Wine Cap is a vigorous mushroom that grows naturally on outdoor beds of woody debris. It grows best on straw (not hay), hardwood chips or sawdust. Hardwood recommendations are soft maple, poplar, box elder, and magnolia. They can tolerate a mixture that includes some softwoods - generally no more than 25%. You can also mix different woody materials.
Wine Cap seems to do better if the beds have a variety of particle sizes, such as a mix of both sawdust and wood chips. Avoid branches or other very large pieces of wood as these take longer to colonize and can create too much air space in the bed. Freshly cut wood is preferred, though Wine Cap can also grow well on more aged materials. Many folks are having success with the chip mixes coming from roadside crews pruning under power lines -- and it's a free resource!
Wine Cap does best in partial shade but can tolerate some direct sun. Ideal locations would be at the edge of fields and woods, around the base of trees, in perennial gardens, or as part of the mulch in vegetable gardens, where annual veggies will provide some shade. Once established, Wine Cap beds require little maintenance. During dry periods, the bed can be watered but do not over-water, as excessive watering can suffocate the mycelium.
- In a suitable location, remove any leaves, etc., down to either bare ground or plain grass. No need to dig a trench, but the bed should be in contact with the soil. One bag of sawdust spawn is enough to inoculate approximately 16 square feet.
- Spread mixed woody material over the soil, about 1'' deep.
- Break up the Wine Cap sawdust spawn and evenly sprinkle the spawn on top of the layer of woody debris.
- Add a second layer of woody debris about 2-3'' thick.
- Thoroughly water the bed.
-
If you don't plan to use immediately, refrigerate your Wine Cap sawdust spawn. Use within 6 months of receipt.

Wine Cap mushrooms are best when braised, grilled, or sauteed. When young, Wine Cap mushrooms can be eaten with the stem and offer a tender yet crunchy texture when lightly cooked in oil. They can also be sliced and mixed into meat sauces or risotto, roasted or braised along with other fall vegetables and served with meat, fowl or fish, added to soups, or stuffed and baked. If using the larger, more mature mushrooms, it is recommended to remove the stems as they become stringy and to slice or chop the cap to ensure even cooking. Wine Cap mushrooms pair well with lemon juice, wine, ramps, nutmeg, fennel, polenta, pasta, quinoa, and rice.

All our spawn is made using organic cultures from our own culture bank. Our sawdust spawn is handmade from a blend of locally sourced, all-natural, organic, and non-GMO woods and supplements from farms and forests in New England and North America.

If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.

Great gift
I bought this as a gift for my father-in-law. He enjoyed reading up on growing mushrooms and the preparation of the growing site. This one gift will probably turn into a hobby and future purchases.

Thanks Thomas! That's awesome to hear! We love to read reviews like this! It makes what we do all the more worth it.

So excited!
Just harvested my first wine cap yesterday - only 2 months after planting! This certainly gives me confidence! I am new to this and am thrilled that it worked. The instructions were clear and easy to follow, and it looks like it will become a solid bed. So pleased! Thanks!

We're so glad the wine caps worked out! Our team is here if you need anything!

it's been 2 whole weeks now
since the package arrived. it was in good condition, very dense with spawn and arrived promptly. i enjoyed prepping the soil and scattering the spawn. i s'pose it's a bit early to expect my first flush? i never ate these kind of mushrooms... this is my second attempt to grow mushrooms at home (seems you can't just buy shitake at the store and put them in the ground, huh?), and i never saw these wine caps "in the field," so to speak. only once ever found morels and... not relevant, huh? yeah, i like the site/store/services. Give it a shot.

Thanks so much, Jason! We really appreciate the kind review.

Wine cap mushroom
This is the 3rd year I’ve ordered these. I have had success with the 2 previous orders but it is too soon to tell for the last order as the local conditions haven’t been right for fruiting to occur.
North Spore
Thanks for sharing, Edward! If you need help with anything, please reach out.

So easy and fun!
This project was so easy and rewarding. We just threw down some straw and aspen shavings, and had little mushies about 3 months later.

First year trying: what a success
This was fun and so successful. Want to try morels next!

Superb mushroom quality!
Newbie here. This my 2nd time buying mushroom sawdust spawn and my first time buying from North Spore. And what a difference in quality! The spawn was very well packed and the smell when you open the package is amazing! I already out the on a straw and mulch bed and they’re colonizing already. I can’t wait for some fall wine cap mushrooms! Will eventually buy other types of mushrooms.

Easy Wine Caps
Wine caps are delicious and so easy to grow. I bought my first kit pretty new to these. I cleared a section out under some trees, laid down a 4' X 4' section of straw, then a layer of wood chips (untreated), broke up the block across the area, another thin layer of straw, and topped it off with more woodchips. I soaked the area real well and then each day I watered like any other garden vegetable. I was impressed how quick they started popping up and how many I had. Now I'm buying more and expanding my mushroom garden.

Clean mycelium
I transferred to agar and to burlap. It is the most beautiful rhizomorphic growth I have ever seen. Burlap took well and is now in the garden walkways and a small shaded patch
