Why home-milled flour is worth the effort

There are few smells more satisfying than freshly milled wheat. When you grind grain at home, you keep the bran, germ and endosperm together. That wholegrain flour is alive with enzymes and oils that begin to fade within days of milling. The result in a loaf is a deep, nutty sweetness, a creamy crumb and a crust that colours beautifully in the oven. Buy wheat berries in 5kg or 10kg sacks, store them cool and dry, and mill only what you need for the next bake or two. Treat your grain like the fresh produce it is.

Home-milled wholemeal behaves differently from shop-bought strong white. It drinks more water, ferments faster and can feel sticky and unruly. Work with it rather than against it, and you will be rewarded with a loaf that tastes of the field it came from.

Feeding a starter with wholegrain flour

A lively starter is the engine of good sourdough. Feed yours with the same home-milled flour you plan to bake with, so the microbial community is already adapted to that grain. A simple schedule works well: keep 50g of starter, add 50g lukewarm water and 50g flour, stir, cover and leave somewhere warm for four to eight hours. It should double, smell yeasty and slightly sour, and be full of bubbles.

If you bake only once a week, store the starter in the fridge and revive it with two or three feeds at room temperature before baking. In a cold country kitchen, stand the jar in a bowl of warm water or beside a woodburner. If the starter smells of acetone or nail varnish, it is hungry — feed it more often and discard more before each feed. Use lukewarm water, around 22–25C, never hot.

Autolyse: the quiet start

Weigh 500g of home-milled flour and 375g of water — about 75% hydration — into a large bowl. Mix with a spoon until no dry patches remain, cover and leave for one to two hours. This rest, called autolyse, lets the bran soften and the gluten begin to form without any kneading. The dough will become smoother and more extensible on its own.

After the rest, add 100g of active starter and 10g of salt. Squeeze and fold the dough until everything is combined. Wholemeal can often take 80% hydration or more, so hold back 50g of the water and add it if the dough feels stiff after the autolyse. A wetter dough gives a more open crumb, but it is harder to handle.

Bulk ferment, shaping and the cold prove

Bulk ferment at 22–24C for four to six hours, giving the dough four sets of stretch and folds in the first two hours. The dough should rise by 50–70%, feel airy and show bubbles at the edges. In a cold kitchen in January, this can take eight hours or more. In a July heatwave, it may be ready in three.

• Summer: use cool water, keep the dough in the coolest spot in the house and shorten the bulk ferment.
• Winter: use warm water, keep the dough near a stove or in a cool box with a hot water bottle, and be patient.

Shape the dough into a tight round or batard, place it in a floured banneton, cover and refrigerate for 8–16 hours. This long cold prove deepens the flavour and firms the dough, making it much easier to score.

Baking in a hot Dutch oven

Preheat your oven and Dutch oven to 240C for at least 45 minutes. Turn the cold dough out onto baking parchment and score it deeply at a shallow angle. Lower it into the pot, put the lid on and bake for 20 minutes. Remove the lid, drop the heat to 220C and bake for another 20–25 minutes until the crust is deep brown and the loaf sounds hollow when tapped. An internal temperature of 96–99C means it is done.

Cool on a wire rack for at least two hours before cutting. If you cut too soon, the crumb will be gummy. No Dutch oven? Use a heavy casserole with a lid, or a baking stone with a metal bowl inverted over the loaf for the first part of the bake.

Adapting to the season and your own grain

Every sack of grain is different. Freshly milled flour, older flour, hard red wheat or soft white wheat will all change how much water the dough takes. Keep notes: flour weight, water weight, room temperature, timings and how the loaf turns out. If the loaf is dense and gummy, ferment it longer next time. If it spreads rather than rises, your starter was weak or the final prove went too far.

Baking with home-milled flour is a conversation with the season. The loaves you make in February will not taste like those in August, and that is exactly the point. Cut a thick slice, butter it while it is still warm, and enjoy the work of your own hands.
