Royal Lee Organics often receives questions about the fineness of the whole grain flour our mill produces. Different recipes call for different degrees of fineness, but for bread and pastry, people want very fine flour. Fine flour makes a light, airy batter and produces a better texture in bread and pastry. We’ve always stood behind the ability of our stone mill to make pastry-fine flour, but we wondered exactly how the flour our mill ground compared to other mills.
So, we put the Lee Household Flour Mill to the test and compared it to two other household mills, as well as two commercial flours. Using the Camsizer XT, a particle size analyzer, the percentage of flour that passes through various mesh sizes determines the fineness of the flour. The results can be seen in the chart below. The horizontal numbers indicate the mesh size. The smallest mesh is at the left, and the widest mesh is at the right. The vertical numbers indicate the percentage of flour that passed through the mesh at the corresponding mesh size.
When used at the finest setting, the Lee Household Flour Mill grinds the whole grain, including the germ and bran, fine enough that more of it passes through the finest mesh than the other household mills, as well as the commercial flours. The wider the mesh, the more the other flours pass through, but this shows how fine the Lee Household Mill is capable of grinding compared to some other options.
