Whole wheat usually means one of two disappointments: a loaf with the nutrition and none of the flavour, or a loaf with flavour and the texture of a doormat. The fix here is small and mechanical. Sift the bran out of the 40% whole wheat fraction, toast that bran in a dry pan until it smells like hazelnut, and stir it back in with the salt. The loaf gains the toasted note that raw bran never develops, and the dough still behaves like a 60% white flour dough.

Sifting, and what the numbers look like

From 400 g of stone-ground whole wheat I get about 340 g of endosperm flour and 60 g of bran. The flour goes into the autolyse; the bran goes into a dry skillet over medium heat for 4-5 minutes until it smells nutty and darkens by one shade. Sifting costs you the very fine bran that passes through, which is fine — that fraction is what makes wholemeal dough gritty.

Hydration at 82% and why the bran is not in the water

Bran absorbs roughly three times its weight in water. If it sits in the dough from the start it takes that water away from the gluten and you get a tight, dry loaf that feels underhydrated even though the scale said 82%. Toasted bran added late absorbs far less because the toasting has gelatinised and hardened part of its surface. The dough stays extensible and the crumb stays open.

Bulk, folds and the box cut

Five coil folds at 35-minute intervals, 3.75 hours of bulk at 26 °C, then 11 hours cold. Shaping is a round boule with the seam down. Scoring is a square box cut with a 10 mm lip: four cuts that meet at the corners and form a lid that lifts off. It is the most forgiving score for a 40% whole grain loaf because it does not depend on one clean ear forming.

  • Preheat the stone 50 minutes at 240 °C.
  • 25 minutes with steam, then 25 minutes dry.
  • Total bake 50 minutes; the crust goes a deep chestnut brown and stays thin.

Whole wheat with sifted, toasted bran keeps for four days in a paper bag. The same loaf with un-toasted bran tastes stale on day two — the difference is not imagination, it is the raw bran going rancid at the surface.
