Milling Your Own Flour for Bread

Milling your own flour is the deepest rabbit hole in bread baking — and one of the most rewarding. Fresh flour smells sweet and nutty in a way bagged flour never does, and it carries flavour and nutrition that’s lost within days of milling commercially. The catch is that it behaves like a different ingredient, so a few adjustments make the difference between a revelation and a dense disappointment.

Why mill your own?

Store-bought flour is milled and then usually stripped of the germ so it can sit on a shelf for months. Home milling keeps the whole grain intact.

More flavour — the intact germ and bran give a sweet, nutty depth that fades fast in commercial flour.

More nutrition — you keep the germ's oils, vitamins, and minerals that white flour discards.

Full control — choose the grain, the coarseness, and how much bran to keep.

But it's perishable — those same oils go rancid quickly — fresh flour is a use-it-soon ingredient.

Choosing a mill

Two main types dominate home kitchens, and both can make flour fine enough for bread.

Stone (burr) mills Grind grain between two stones for an even, traditional flour. Prized for flavour and versatility across coarseness settings. Examples: Mockmill, KoMo.

Impact (micronizer) mills Spin steel fins at high speed to shatter the grain into a very fine flour, fast. Great for light loaves and pastry. Example: NutriMill Classic.

Attachments & manual Stand-mixer mill attachments and hand-crank mills work but are slower and less fine — fine for occasional milling or a workout.

Choosing your grain

The berry you buy decides the bread you get. For strong, well-risen loaves you want hard, high-protein wheat.

Hard red robust, classic wheat flavour

Hard white milder, lighter colour

Spelt / einkorn / rye distinct flavours, often blended

Buy whole berries from a mill or homebrew/baking supplier, store them dry, and mill only what you need for a bake. Soft wheat is for cakes and pastry — it won’t build the gluten a loaf needs.

Baking with fresh flour

Fresh whole-grain flour is thirstier and livelier than bagged white flour. Two adjustments cover most of it.

1
Raise the hydration The intact bran absorbs a lot of water. Add more water than your white-flour recipe calls for, and rest the dough so the bran can fully hydrate.
2
Shorten the bulk The active bran and germ ferment fast — watch for a 30–50% rise rather than a doubling, and don't leave it as long as a white loaf.
3
Handle gently Whole-grain dough has more bran cutting the gluten, so build strength with folds rather than aggressive kneading.
4
Expect a denser crumb A 100% fresh-milled loaf is naturally tighter than white. Sifting (next) lightens it if you want more lift.

Sifting for lighter loaves

If you want a loaf closer to white bread but with fresh-flour flavour, sift out some of the bran. Pass the milled flour through a fine sieve or bolting cloth and set aside the coarse bran that stays behind — what passes through is a higher-extraction “white” flour that rises taller with a more open crumb. Sift out more for a lighter loaf, less for a heartier one. Save the reserved bran to add to another bake, sprinkle on crusts, or stir into porridge.

Storing fresh flour & berries

×Fresh flour goes rancid within days to weeks at room temperature — the germ oils oxidise
×For best flavour, mill just before you bake
×Store leftover flour airtight in the fridge (weeks) or freezer (months)
×Let chilled or frozen flour warm to room temperature before mixing
×Whole berries keep for a year or more stored cool, dry, and airtight

Whole wheat berries are shelf-stable, so the simplest routine is to store berries, not flour, and mill fresh each bake. That way you always get peak flavour and never lose a batch of flour to rancidity.

Frequently asked questions

Is it worth milling your own flour?+

For flavour and nutrition, yes. Freshly milled flour keeps the whole grain — bran, germ, and oils — so it's more flavourful and nutritious than store-bought flour, which is usually stripped of the germ for shelf life. The trade-offs are the cost of a mill, the effort, and that fresh flour is perishable and behaves differently in the dough.

What kind of mill do I need to make bread flour?+

A countertop grain mill. Stone (burr) mills grind between two stones for a traditional, even flour, while impact (micronizer) mills use spinning steel to make a very fine flour fast. Popular home options include Mockmill, KoMo, and NutriMill. Both types can make flour fine enough for bread; stone mills are prized for flavour, impact mills for speed and fineness.

Which wheat berries are best for bread?+

Hard wheat, which is high in protein and forms strong gluten. Hard red winter or spring wheat gives a robust, classic wheaty flavour; hard white wheat is milder and lighter in colour. Soft wheat is for pastry, not bread. Spelt, einkorn, and rye are also popular for their distinctive flavours, often blended with hard wheat.

Do I need to change my recipe for fresh-milled flour?+

Yes. Fresh whole-grain flour absorbs more water, so raise your hydration and give the dough a longer rest to let the bran hydrate. It also ferments faster thanks to the active bran and germ, so shorten your bulk. Expect a denser crumb than white flour unless you sift some bran out.

Should I sift home-milled flour?+

It depends on the loaf. Sifting removes some of the coarse bran, giving a lighter, taller loaf with a more open crumb — this is called adjusting the extraction rate. For a rustic, 100% whole-grain loaf, don't sift. For something closer to a white loaf but with fresh-flour flavour, sift out a portion of the bran (you can save it to add back or use elsewhere).

How long does fresh-milled flour last?+

Not long at room temperature. Because the oil-rich germ is intact, fresh flour starts to go rancid within days to a couple of weeks at room temperature. For best flavour, mill just before baking. To store, keep it airtight in the fridge for a few weeks or the freezer for several months, and let it come to room temperature before using.
