Absorption math for Organic Bread Flour at 72%

A recipe written for bread flour at 72% hydration, when substituted with 100% Organic Bread Flour, becomes 71% effective hydration (because Organic Bread Flour absorbs 1% less water). Same as conventional bread flour but allow 2-3% more proofing time (slightly weaker gluten on some batches). Autolyse 45-60 min. 3-4 stretch-and-folds.

Technique at 72% hydration

Dough requires strong gluten development (3-4 stretch-and-folds or coil folds). Shaping benefits from cold retard. Handle with wet hands or flour-dusted bench scraper.

How the math works

Total water = flour × hydration %. Your levain contributes 50 g flour + 50 g water — both count toward the totals. You add only the remainder as fresh flour and water.

Salt % is computed on total flour weight, not final-dough flour.
