What Is Stone Milling?

Stone milling is an old world process where the grain is sheared into flour by rotating stones. This low-temperature process preserves the integrity and nutrition of the whole grain. Even our more finely sifted flours have part of the whole grain in them. Our flours are completely untreated, so no bleach, bromate or enrichments are added.  Instead, you will experience enhanced flavor and wholesome nutrition.  Because all the natural oils in the grain is preserved, our products have a shelf life of one year, or longer if you store them in your fridge or freezer. 


Most of our products are shelf stable for up to one year after it’s milled and packaged.

“Best by” dates are printed on each product.

To extend the life of your product and keep it at peak freshness, we recommend storing it in your fridge or freezer to preserve its natural oils.

Do you have an onsite store at the mill in Queen Creek, AZ?

We are not able to accommodate onsite purchases at this time. We are planning to offer an “order online, pick up in person” program very soon. Subscribe to our emails to be the first to know when this service starts.

In the meantime, please shop online where we ship direct from the mill and offer free shipping on orders over $75 and flat rate shipping on all other orders.

Are your grains genetically modified (gmo)?

We don’t grow or sell any GMO products. And fortunately, there is no GMO wheat commercially available for production or sale in North America at this time. Our corn products are certified non-GMO.

Are your grains Organic? Pesticide free?

Our heritage grains are not certified organic but they are grown using natural farming methods. We do not use chemical fertilizers, pesticides or glyphosate. We use a mild herbicide on the field borders before our wheat reaches the grassy stage. But we never spray the wheat berries themselves with anything whatsoever.

Do you mill at the historic Hayden Flour Mills in Tempe?

No. Our stone mill is not at the historic Tempe Mill. The old mill is now a historic site owned by the City of Tempe and used as an event space. We currently mill our flour on Sossaman Farms in Queen Creek -- this is the same farm where our grains are grown!


At Hayden Flour Mills, our goal is to provide our community with the highest quality of goods, so we strive to ensure our milling practices reflect that.

If you have an issue with your order, please reach out to us at info@haydenflourmills.com and we will assist you. Please note, due to our food safety and sanitary protocols, we do not accept returns.
