10 Best Organic Flour Mills 2025 in the United States

King Arthur Unbleached Organic Bread Flour is a top choice for home bakers who want high-protein flour to make yeasted breads, pizza dough, and artisan loaves. With 12.7% protein, it helps dough rise well and gives bread a nice texture—better than many standard flours. Being organic, non-GMO, and kosher certified, it appeals to those seeking clean, high-quality ingredients without preservatives.

The 5-pound packaging is a practical size for regular baking and should be stored in a cool, dry place to maintain freshness. Since this is a pre-milled flour, it doesn't require any grinding, making it very easy to use for anyone who wants to skip the grinding step. If you're specifically looking for a flour mill to control grind size or experiment with fresh grain, this product won't meet that need.

This flour suits bakers who prefer convenience paired with premium quality flour. King Arthur's long-standing reputation adds trust, and the flour works well for a wide range of yeast baking tasks. It is an excellent organic bread flour for home bakers focused on flavor and performance, but not suitable if you want to mill your own grain.

The Great River Milling Organic All-Purpose Flour offers a versatile and high-quality option for various baking needs. This flour stands out due to its USDA-certified organic status, ensuring no synthetic pesticides or fertilizers are used. It is also unbromated and unbleached, enhancing its nutritional value and natural flavor.

The flour boasts balanced protein and gluten levels, making it suitable for bread makers and other baked goods where a good rise is desired. The 25 lb pack is ideal for serious family cooks or small businesses, adding convenience for bulk use in bakeries, cafés, and restaurants.

Made from a blend of non-GMO hard red spring wheats, this flour is packed with essential vitamins and minerals, contributing to a healthier diet. The large package size might be cumbersome for casual home bakers with limited storage space.
