Turn a measured batch into a cost input

Weigh the dry grain before milling, then weigh the flour you intend to use after the same sifting and collection choices you want to compare. The notebook calculates usable yield as output ÷ input × 100.

For example, 1,000 g of grain and 950 g of usable flour is a 95.0% measured yield. If a more heavily sifted batch produces 850 g, enter 85.0% instead. That difference describes what you kept for those batches; it does not by itself measure mill performance.

Save the batch, copy its yield below, then open the flour cost calculator and enter the percentage in Usable flour yield. Use the current delivered cost of the same grain. One batch is an input for a scenario, not a promise about future savings.

Compare repeat batches fairly

Keep the grain, scale and definition of usable flour consistent, and change one documented setting or sifting choice at a time. Compare the notes as well as the percentage: a lower yield can be the intended result of removing more bran, not evidence of a machine problem.

Grain-to-flour yield, sifting and flour identity

Measure grain-to-flour yield by weight, understand what sifting removes and learn why a fine grind alone does not make white or all-purpose flour.

How to use a grain mill for your first batch

Record the details you will need next time

Give the grain a useful name, such as its variety plus a supplier or bag reference that helps distinguish it from your other grain. Add the exact mill and the setting you used. In the notes, record whether you sifted, changed a recipe or noticed a collection loss. A setting such as “3” is most useful alongside the model and grain; it is not a transferable fineness measurement for another mill.

Measure usable flour consistently

Both weight fields use grams. Weigh the grain before milling and record the flour you intend to use after any sifting or collection losses. The notebook divides usable output by grain input and displays the percentage. An illustrative 1,000 g input and 920 g output gives 92% yield. Record removed bran or other losses in the notes rather than silently changing what “usable” means between batches. The yield guide explains the distinction.

Make a comparison you can interpret

When you want to refine a routine, keep the grain and weighing method consistent and change one recorded choice at a time where your mill’s instructions permit it. Compare the notes as well as the percentage: a lower yield may reflect a deliberate sifting choice. Yield alone does not tell you whether a flour performed better in a recipe. Your records can supply a measured yield for the flour cost calculator without turning one batch into a guarantee.

Keep a separate copy of records that matter

Entries stay in this browser profile on this device. Confirm that a saved batch appears in the list, then use Export JSON backup to download a separate copy when you need one. Export does not create an account, sync devices or restore records automatically; this notebook has no import control. Clearing site data or losing access to the browser can remove the working notebook. Deleting an entry here does not delete a previously downloaded copy. Keep sensitive personal details out of notes.
