The humble rye grain, Seceale cereale, has been around for possibly 13,000 years according to Wikipedia, however it was only in 1973, Birmingham, UK, where Jonathan Bourbon decided to lend his namesake to a new drink that he’d invented and made it matter. Before this everyone had assumed that rye was absolutely pointless unless you were on Slimming World and needed to eat crackers. At this time, they were correct.
However, thanks to the boffins in the MycoPunks lab, humanity has since discovered that rye actually makes a pretty sweet bit of food for mushrooms to eat, because they don’t care about eating things that taste nice, they just want the nutrient source. Rye’s got that in abundance, so thanks to modern science we’ve now discovered a staggering two things you can do with rye, you can make it into bourbon to put in a nice drink or you can grow some happy mycelium on it.
Just to get in front of any little contrarians out there: Bourbon biscuits have nothing to do with rye grain so if you try and bring biscuits up on our helpful Discord community channel then you’ll be soundly mocked by the Rye Crew.
What do we do with the rye to make it ready to grow mushrooms on? We wash it, then we soak for 24 hours, then we simmer it for a little bit. This makes sure that the grain is a bit easier for the mycelium to access, and helps the rye absorb a bit more moisture. We then put it into either a 4T or a 10T Unicorn bag, depending on how big you want it, and we pressure cook it for 2.5hrs at 15psi so that anything nasty that might have been in there is as dead as fuck.
Why choose rye for your mushroom grow? It can absorb a fair bit of moisture without bursting, and it’s full of copper, magnesium, various proteins, and B vitamins, which makes sure your mycelium gets the best possible start in life. Awwww, that’s nice, isn’t it?
✅ Perfectly hydrated rye keeps your mycelium in top nick
✅ Sterilised for 2.5 hours at 15 PSI so proper clean
✅ We use official Injection port Unicorn Bags, not stick on injection ports.
✅ Loved by most of the mushrooms that you’d bother to grow
✅ Excellent bulk discounts available
✅ Needs to be added to your substrate of choice once colonised

Storage:
- Remove from the packaging straight away

Sterile Organic Rye Grain for Mushroom Spawn Production
Video Instructions for inoculation
We made a nice little video ages ago which shows how to inoculate your grain bag.

As a beginner, I wanted grains that I could inoculate and trust I would get perfect results even if I didn’t follow the helpful advice from the mycopunks video tutorial. These guys clean, steam and sterilise everything, using the best unicorn bags! It’s the best spawn grain I’ve used.
I’m consistently amazed how quickly I see that white mat of mycorrhizal growth starting to appear with these.
Great spawn, easy to use.
One of the two bags I bought ended up contaminated after leaving it in the packaging for a couple months. Would have expected they'd be sterile for a long time if left untouched
Hi Ben,
The reason we put stickers on the parcels telling you to remove from the packaging is because condensation builds up on the filter and allows contamination to bridge through into the bag. Whilst we would expect them to stay sterile out of the packaging the grain will dry substationally over time and quality will decrease.
All the best,
Chris
Great so far. Fast delivery, great company & staff
Great product, fully colonised with my jmf ss ! No issues, no contamination, and great support from myco as always! Repeat customer !
I've Tried a Few. I Can't Fault This Stuff.
This and red milo/ Giant millet
are my new go too. Quick and easy.
Brought two bags one was good the other contaminated hoping next time Will be better
Quick delivery, quality product, my myclium baby is spreading across it as a rapid rate
Seamless experience
Lovely package. Lovely team behind everything!
Best grain around! I don't go anywhere else!
5/5
I ordered a bag of sterilised maize, it was an economic option and it arrived promptly. I have inoculated the bag and the mycelium seems to be growing OK. I have used maize to grow Lion's Mane before and I am glad that Mycopunks have started to supply this as well as the more common grains.
Ok very Good
Grain colonised really well, perhaps not as quickly as anticipated, but solidly with zero issues.
Thanks for a speedy delivery and a top quality service/product.
Your loyalty system is well valued and appreciated.
I'll be definitely shopping again soon!
Reliable, sterile products that do the job every single time. The level of care and class put into these products really shows, flawless!
Fab company quick to answer any questions a d fast delivery
At the present time of writing this my mycelium is doing very well, I think I have the Reishi in this one, sorry if it seems a touch vague but I have several others on the go at the same time. I have Oyster, Lions Mane (which I’m well surprised as to how that one is just going bananas) also Reishi and a couple of three other types on the go. I am using millet, CVG, and two others which @ 10-2-12 just escapes me at present. But I definitely love the millet. So if you’re interested in it defo give it a try, and I doubt if you don’t order more after your first purchase, you’ll see great results as I have. Good growing.
Over all very good
I order 5 bags at a time now
The last 3 times
One in 5 of those bags has contaminated
Excellent and fast delivery
great stuff
Working very well for jar spawn, not made sterile before and needing some quickly so I got this stuff
Good quality, fast delivery, very happy
Awesome
Fantastic grain every time.
Fast turn around.
