How to Mill Your Own Flour at Home
Feed clean, dry whole grain into a grain mill set to your desired fineness, collect the flour, and use or store it quickly. Fresh whole-grain flour has natural oils that go stale fast, so mill close to baking or freeze what you keep.
Milling your own flour is simpler than it sounds: dry grain goes in, fresh flour comes out. What you gain is flavour and nutrition from the whole grain; what you must manage is that fresh flour does not keep like the bag from the shop.
Step by step
- Start with clean, dry grain. Only dry, hard grains and legumes mill well, see what grains you can mill.
- Set the fineness. Choose coarse (meal) to fine (flour) on your mill. Finer flour suits bread and cakes; coarser suits polenta or porridge.
- Mill in the amount you need. Feed grain steadily; let the mill work at its own pace.
- Sift if you want it lighter. Whole-grain flour bakes fine as-is; sifting out some bran gives a finer crumb.
- Use it fresh, or store cold. Bake soon, or refrigerate/freeze the rest.
Adjusting for baking
Fresh whole-grain flour absorbs water differently from white flour and can bake denser. Expect to adjust hydration slightly and, for lighter loaves, blend with sifted or white flour while you learn. A finer grind and a well-developed dough help.
Storing fresh flour
| Storage | Best-quality window |
|---|---|
| Room temperature | A few days |
| Refrigerated (airtight) | A couple of weeks |
| Frozen (airtight) | Several months |
Airtight storage is essential; a vacuum sealer or vacuum container helps slow the oils going off. Choosing a mill? See the best electric grain mills and the best grain mill for home baking.
Frequently asked questions
Is home-milled flour better than store-bought?
Fresher, and it keeps the whole grain (bran and germ) with more flavour and nutrients. The trade-off is those oils go rancid faster, so it does not store as long as white flour.
Do I need to sift home-milled flour?
Only if you want lighter results. Whole-grain flour bakes as-is; sifting out some bran gives a finer crumb closer to white flour.
How long does fresh-milled flour last?
Use within a few days at room temperature for best flavour; refrigerate for a couple of weeks or freeze for months, as the germ oils oxidise quickly.
