Grinder Flour Fineness Page

Flours from the different grinders We start out with the coarsest grinds on the left and progress to ever finer flours as we move to the right. The finer the grind, the better the gluten will develop - the better the flour for bread making.

1. First pass through the Corona or Victoria grinder. The wheat is just cracked. Some whole kernels of wheat make it through. Grind Fineness: 1.
2. Second pass through the Corona or Victoria grinder. It's finer than the first grind, but still has the coarseness of cracked wheat. This is not a good grinder for bread making. Grind Fineness: 2.
3. Germade. This is a reference point to give you some idea where the surrounding flours are on the scale. Grind Fineness: 4.
4. Back to Basics or Family Grain Grinder after the first grind. The flour is still too coarse to make good bread in my opinion. Grind Fineness: 6.
5. Back to Basics or Family Grain Grinder after the second grind. The flour fineness now approximates the Country Living Mill's fineness after it's first grind. Grind Fineness: 8.
6. The Country Living Mill, Diamant, Little Ark with burrs and Silver Nugget with burrs. This is not a super fine flour but good enough for bread making. Grind Fineness: 8.
7. The Silver Nugget with Stones. Grind Fineness 8.5.
8. The Little Ark with Stones. Grind Fineness 8.5.
7 & 8. The Nugget and Ark produce a really nice, fine flour, but not quite as fine as my electric impact grinder (flour #9) Grind Fineness: 9. These particular samples were ground with the stone spacing at 0.005". Later, I ground some wheat with the stones just touching. On that grind the wheat was turned into flour equal to what my impact grinder could produce. The less the stone spacing the slower the grind but the finer the flour. These manual grinders can also just crack the wheat if their stones/burrs are set far enough apart.
9. Flour ground with my impact grinder - almost the consistency of white, processed flour. This sample, coming from an electric grinder, was also a reference point to compare the other flours to. It's a little darker in color than white flour because of the wheat bran but if you conduct 'Al's Pinch Test' you will feel very little difference between the two flours.
10. White, processed flour - reference point. Flour Fineness: 10.

Al's Pinch Test: Take a small pinch of flour between your thumb and index finger... Or if you are comparing two different flours, take a pinch of each flour with each hand pinching the flour between your thumb and index finger. Move your fingers back and forth as the flour falls out from between the loosely pinched fingers. Feel the roughness of the flour. There's not a thing scientific about it, but it does give some idea of flour fineness. The finest flours are completely powdery with no granules felt. I call this a fineness of #10. Cornstarch and baking powder would also have a fineness of #10. Next comes #9 where there is just a hint of something being there besides powder. #10 is so close to #9 that you must be feeling the two different flours at the same time with two different hands to tell the incredibly small difference. Flours where tiny granules can easily be felt I have given a rating of #8. Fineness #6 is a coarse flour with large granules and very little powder between them But #6 is still finer than salt or white sugar. Salt and sugar would fall around #5. I'd put dry germade, or Cream of Wheat at about a fineness of #4. And cracked wheat gets a fineness of #1 or #2 depending on how coarse it is. This paragraph should help you understand the graph below.

E- Country Living Mill and the Diamant
F- Little Ark with burrs
G- Silver Nugget with burrs
H- Little Ark with stones
 I- Silver Nugget with stones
