Mycology Basics Rye Berries for Mushroom Spawn - Organic, Triple-Washed Rye Grain (5 lbs)

Premium, Purified Rye Berries for Mushroom Spawn

Mycology Basics Rye Berries are designed for reliability. Each berry is organic, regeneratively grown, and triple washed, delivering a clean substrate that's ready for your next cultivation project.

What makes these rye berries stand out

Our washing process goes beyond the standard rinse: three rounds at elevated temperatures helps remove errant seeds, stalks, dust, and debris. The result is a grain that's closer to ready-to-use out of the bag, saving you prep time and reducing contamination concerns.

• The cleanest rye money can buy—less stray material and fewer issues to wash away.
• Washed longer and at higher temperatures to reduce contaminants for mycological use.
• Resealable bag for reliable storage and long shelf life.

Performance you can count on

Rehydration is a key benefit: the berries absorb water to roughly 2x their dry mass, compared to about 1.7x for lower-quality rye. This means you reach the needed moisture level faster and with less guesswork during your prep.

• Higher hydrated weight than many conventional grains, supporting consistent inoculation workflows.
• Certified OMRI Organic and non-GMO, grown with regenerative farming practices for nutrient-dense grain.

Typical uses and outcomes

Whether you hydrate for grainspawn, mill for flour, or create a rye mash, these berries offer dependable performance in professional and home labs alike. The official rye berries of choice for several Midwestern breweries and distilleries speak to their clean nature and protein content.

Storage and sustainability

Packaged in a resealable bag, the rye stays fresh between uses. Choosing regenerative farming practices supports soil health and reduces environmental impact over time.
