A grain mill is a device used to grind grains into flour or meal. It can be powered by hand, electricity, or water, and comes in various types, including stone mills, hammer mills, and roller mills. Grain mills are commonly used by bakers and home cooks to create fresh flour from grains like wheat, corn, and rice. Using a grain mill allows for better control over the texture and freshness of the flour. Freshly milled flour retains more nutrients and flavor compared to store-bought options. Many people enjoy using grain mills for making homemade bread, pastries, and other baked goods.
