At Proof, we’re passionate about grains that tell a story. Each flour we mill connects us to centuries of baking traditions, bringing history and flavor to every loaf. Here’s a closer look at a few of our most special grains:

Rouge de Bordeaux: Grown just outside our city, this ancient grain dates back to the 1600s in France. Its deep red hue and high protein content make it perfect for bread, whether as a base flour or on its own for a rich, darker loaf.

White Sonora: Often called Arizona’s flour, this heirloom grain was introduced hundreds of years ago and is ideal for cookies, breads, and blends. Its mild flavor and fine texture make it a versatile favorite.

Khorasan: Known for its golden hue and exceptional crust development, this Persian-origin grain shines when used as a scald or blended with other flours.

Rye: A naturally sourdough-friendly flour, rye adds bold flavor even in small quantities. Use it on its own for a traditional loaf or as part of a wheat blend.

Buckwheat: Technically a legume, buckwheat is gluten-free and rich in flavor. It’s a great addition to wheat-based recipes or can be used on its own for gluten-free baking.

We’re also improving how we share these flours with you:

Smarter Packaging: New, compact bags for better storage and shipping.

Lower Shipping Costs: Expanding to more carriers to make delivery more affordable nationwide.
Our freshly milled flours are packed with flavor, aroma, and nutrition—perfect for those who want to bake breads and pastries that are as unique as their journey. These are grains you won’t find in grocery stores, rooted in heritage and tradition.

Our next online flour release is coming soon, and quantities are limited. In our last trial, we sold out in just five hours—so if you’re eager to bake with Proof flour, stay tuned for updates!

Thank you for supporting this passion project and helping us bring heirloom grains to home bakers across the country.
