Wheat germ and bran bread with poolish
A poolish loaf with 10% whole wheat, wheat germ and bran; suited to focaccia.
Method
01 · Build poolish
12–14 h at 18–21°CUse: P
Mix P flour and yeast, then stir in all P water until thoroughly combined. Cover and leave at 18–21°C.Ready when: Bubbly and roughly tripled; bubbles break at the surface every few seconds.

01 Build poolishUse the poolish when it is well expanded and covered in lively bubbles. 02 · Mix final dough
A few minutesUse: D + all mature P
Mix the D flour(s), salt and yeast, wheat germ and dough bran. Pour D water around the poolish to release it, then tip all of it into D. Wet your hand and alternate 5–6 thumb-and-forefinger pinch cuts with folds until evenly combined. No autolyse is used.Ready when: Uniform dough with no unmixed lumps of preferment.

02 Mix final doughMix in all the ripe poolish, wheat germ and dough bran; pinch and fold to a uniform flecked dough. 03 · Fold and bulk
2–3 h from end of final mixUse: Mixed dough
Apply 2 sets during the first hour. For each set, wet your hand; stretch one edge upward only to resistance and fold across. Repeat around 4–5 edges until the dough firms, then turn the whole mass seam down. Let it relax before the next set. Cover between folds and during the remaining rise.Ready when: About 2½ times its initial volume.

03 Fold and bulkFold gently to build strength while keeping the dough connected and untorn. 04 · Divide and shape
A few minutesUse: Risen dough; dusting flour
Ease dough onto a lightly floured counter without tearing. Divide equally. Fold each piece’s edges inward to enclose it, turn seam down onto a clean unfloured patch, and cup and drag toward you while turning to make a medium-tight ball. If using the optional bran coating, prepare the baskets and moisten the seam as in the next row before placing the loaves. Otherwise set seam DOWN in a well-floured basket; flour the top and cover.Ready when: Two rounds with moderate tension and intact surfaces.

04 Divide and shapeDivide evenly and cup the two rounds until their surfaces hold gentle tension. 05 · Optional bran crust
During shapingUse: Extra finish bran and spritz water
Before placing the shaped loaves in their baskets, dust each empty basket with flour, then scatter 10 g extra bran inside. Lightly moisten the seam side of each shaped loaf and place seam DOWN onto the bran. Flour the tops lightly and cover.Ready when: A light, even coating; avoid loose piles of bran.

05 Optional bran crustFor the optional coating, scatter a thin layer of bran into the floured baskets before adding the moistened seam sides. 06 · Proof
About 1 h; preheat promptlyUse: Shaped loaves
Proof covered. Gently press the loaf with a floured fingertip to make a small dent: a slow, incomplete return indicates readiness; immediate spring-back means wait; no return with a slack loaf suggests overproofing.Ready when: Loaf aerated and expanded; indentation recovers slowly and incompletely.

06 ProofProof with the seam-side coating underneath in the baskets. Judge expansion and slow partial recovery from a gentle press. 07 · Preheat during proof
At least 45 min at 245°CUse: Oven and lidded pots
Put lidded Dutch ovens on the middle rack and heat fully. If using one pot, refrigerate the second room-proofing loaf about 20 minutes before baking the first; reheat the empty pot 5 minutes between loaves.Ready when: Pots and oven fully heat-soaked.

07 Preheat during proofHeat the covered pots thoroughly while the loaves finish proofing. 08 · Load and bake
245°C throughoutUse: Proofed loaf
Invert the loaf onto a lightly floured counter, then carefully lower it seam UP into the hot pot, avoiding the hot sides. No scoring is needed: the seam opens naturally. Use mitts for the pot and lid. Bake covered 30 minutes, then uncovered about 20 min. Check from 15 minutes uncovered.Ready when: Crust at least medium-dark brown all around; bran can be deeply colored.

08 Load and bakeThe optional bran coating can brown quickly, so begin checking after the first part of the uncovered bake. 09 · Cool
At least 20 minUse: Baked loaves
Turn the bread out and cool on a rack with air beneath it. Wait at least 20 minutes before slicing; allow longer if the center is still very hot.Ready when: Crumb begins to set; crust stays aired on the rack.

09 CoolCool the bran-coated loaves on an open rack before slicing.
What to look for
| Stage | Look and feel | Needs attention |
|---|---|---|
| Mature poolish | Bubbly and roughly tripled; bubbles break at the surface every few seconds. | Using a quiet, underdeveloped build or waiting until it has collapsed well past peak. |
| Bulk dough | About 2½ times its initial volume. Folds should give increasing support. | Tearing the dough during folds or judging only by time. |
| Proof | A gentle finger dent returns slowly and incompletely. | Waiting until the whole loaf is fragile or collapses at a touch. |
Troubleshooting
| If you see | Likely cause | What to do now | Next time |
|---|---|---|---|
| Poolish is ready too early | The room was warmer than the reference recipe’s overnight reference temperature. | Use the build at its mature stage if possible; do not deliberately leave it collapsing for hours. | Use a cooler location or adjust the next build’s water temperature and timing. |
| Little rise by the stated time | Cooler dough or room; weak or inaccurate yeast dose. | Check dough temperature and expansion. Allow more time in a gently warm place; continue only when the recipe’s volume cue is reached. | Weigh yeast carefully and record final dough temperature; adjust the next batch’s water temperature. |
| Loaf spreads or collapses at loading | Final proof went too far or shaping left insufficient tension. | Load gently and bake promptly; expect reduced height. | Begin checking early, particularly in warmth. Shape with moderate tension and refrigerate a second loaf while the first bakes. |
| Dark bottom but pale upper crust | Uneven oven heat or a rack too close to the bottom element. | Check oven temperature and finish by crust color while monitoring the base. | Use the middle rack and a fully heated pot; verify actual oven temperature. |
Recipe notes
- The P ingredients are part of the total formula. The D row saying “all of P” is a transfer, not another portion of flour, water or yeast.
- Plan the overnight rise for 18–21°C; warmer rooms shorten preferment maturity and dough rise.
- The poolish’s useful peak lasts about 2 hours in a cool room, nearer 1 hour above 24°C.
- Use the entire poolish build, including its small yeast dose; its mass is about 1,000 g.
- Nominal baker’s percentages use 1,000 g flour. The additional 50 g wheat germ and 20 g bran are listed at 5% and 2%; neither is added to that denominator. Bran coating is extra.
