Great River Organic Milling 25 Pound

I have been using this product in my mycology hobby. It is good quality and clean at a reasonable price. 2/1/2026 received my latest order, good quality as usual.

I use this as grain spawn for mycology and it's nice because it's so clean right out of the bag, there's little to no dust, or other plant particles that need to be cleaned out. I love eating it raw after it's soaked and lightly boiled.

Great River Milling grain are just that, great. Timely delivery and awesome product. I will be baking today after growing a fresh starter in three days.

I was kind of torn on whether or not to order because reviews were so mixed however, I was pleasantly surprised to see there were no bugs and little to no pieces of anything other than grain. I really wanted to start milling my own flour for my sourdough starter, but finding grain that’s organic and yet at a reasonable price is really hard. As of right now, this is the best grain that’s ready to use I have found, price and quality wise. I will continue to order from them in future, however the moment the quality changes I will update my review.

I bake my rye bread using Great River Organic whole Grain Rye. Berries for years and the product never disappoints. The bread is delicious and rises pretty well for rye flour. The packaging is very good. Will buy it again.

Exactly what I ordered. Perfect price and product. Fast shipping.

I wanted to use this as a cover crop, it works however I had to pick through it because of a small amount of weed seeds. It's not ergot ergot is very light and fluffy. These seeds are just as heavy as rye and about the same shape, probably impossible to separate by mechanical equipment.

I’ve been using these rye berries as grain spawn for mycology and I’ve had great success. Yes, some grains will burst after boiling or pressure cooking but that’s to be expected (it’s less than 1% in my case). I’ve soaked for 12-36 hours with no visible mold growth, but yea they will gain a fermented kinda funk to them after a long soak, but that’s the point - you want latent spores to germinate so pressure cooking will kill them off. Dormant endospores are very heat resistant, you need them to germinate to kill them off. Anyhow, you can probably get a lot more cheaper at a tractor supply store but this was more than enough grain to last me over a year, and delivered to my door. Best deal I’ve seen for rye berries on Amazon by far, and I’m highly satisfied with the quality.
