Stone burr mills are the most traditional and produce an exceptionally fine quality of flour. Mills use a pair of grinding stones made from a durable material, such as granite or a similar material, to slowly grind the grains into flour. This method ensures a consistent texture and preserves the nutritional value of the grain.
