The secret to loaf mastery. Your choice of flour makes a very big difference in bread baking: flours with a higher protein content create loftier yeasted breads. Our 100% organic bread flour is 12.7% protein - a full point higher than other national brands. It strengthens the rise, so your breads are lofty and perfectly textured every time. Certified 100 percent organic by Quality Assurance International (QAI) and approved organic by the USDA. Certified kosher. Use it for all your yeast baking, from bread (including bread machine loaves) to rolls to pizza. Combine it with whole wheat flour to add extra height to dense whole grain baked goods that need a little lift. Flour this good doesn't happen by accident. It's the result of attention to detail, consistency in milling, and our desire to ensure that each and every person has the very best baking experience possible. Founded in 1790, King Arthur Flour is a 100% Employee-Owned Company and the nation’s premier baking resource, offering everything from top-quality baking products to inspiring recipes.
