Baking with freshly milled flour

What is different about fresh flour?

• It contains everything. Whole-grain flour includes bran and germ. Bran soaks up water slowly and its sharp edges cut gluten strands; the germ adds oil and flavour.
• It is lively. Whole grain carries more nutrients for yeast and bacteria, so fermentation tends to run faster than with white flour.
• It is warm. Flour comes off the stones a little above room temperature. Use slightly cooler water if you aim for a specific dough temperature.

Water: more than you think, added in stages

Whole-wheat doughs usually want 75–85% hydration (water as a percentage of flour), compared with 60–70% for many white-flour breads. Bran keeps absorbing water for half an hour or more, so a dough that feels sticky at mixing often firms up later. Mix with most of the water, rest, then add the rest if the dough still feels stiff.

Autolyse and soakers

An autolyse means mixing just flour and water and leaving it 30–60 minutes before adding salt and leaven. With whole-grain flour it softens bran and makes the dough noticeably smoother. For coarse-milled grain or cracked kernels, use a soaker: cover the coarse part with water (and the recipe's salt) the night before.

Handling bran

For a lighter loaf without losing the nutrition, sift out the coarse bran, then soak it in some of the recipe water (or scald it with boiling water) and add it back at the end of mixing. It still ends up in the bread, but it no longer cuts the gluten while you knead.

Fermentation timing

Because whole grain ferments faster, judge by the dough, not the clock. Look for a dough that has grown noticeably, feels airy and shows bubbles on the sides of the container. If your dough over-proofs, reduce the leaven (for example from 20% to 10% starter) or ferment cooler.

A first 100% whole-wheat sourdough

1. Mill the wheat on the finest setting. Mix it with 360 g of the water; rest 45 minutes.
2. Add starter, salt and the remaining water; squeeze and fold until even.
3. Ferment at room temperature with three or four sets of stretch-and-folds in the first two hours, until the dough has grown by roughly half and looks airy.
4. Shape, place in a floured basket or tin, and proof (or refrigerate overnight).
5. Bake hot, covered for the first part, until deep brown. Cool completely before slicing.

The quantities above are a starting formula, not a guarantee. Grain, mill setting and kitchen temperature all change the result.

Different grains, different rules

Spelt prefers less water and gentle mixing. Rye needs sourdough acidity and a tin rather than kneading. Einkorn makes a sticky, weak dough that bakes best in a tin or as flatbread. Details for each are in the grain guide.

Frequently asked questions

Do I have to age freshly milled flour?

No. Plenty of home millers bake with flour minutes after milling and get excellent bread. Commercial white flour was traditionally aged to improve its baking behaviour; if a fresh-flour dough feels slack to you, try a slightly lower hydration, a longer autolyse, or letting the flour rest before use, and see what works for your grain.

Why is my whole-grain loaf dense?

The usual causes are too little water (whole-grain flour needs more), under-fermentation, or sharp bran cutting the gluten. Raise hydration, give the dough an autolyse, and watch the dough rather than the clock.

Can I swap fresh flour 1:1 into a white-flour recipe?

By weight, roughly yes, but add water: start with about 5–10% more and adjust. Expect a faster fermentation and a denser, more flavourful crumb.

Why does my fresh rye dough turn gummy?

Rye is rich in starch-digesting enzymes. Sourdough acidity tames them, which is why traditional rye breads are almost always sourdough breads. Bake rye fully and let it rest a day before slicing.
