Is 72% hydration right for All-Purpose Flour?

All-Purpose Flour's workable hydration range is 6072%. Its absorption multiplier is 0.97× bread flour. At 72%, you are in the sweet spot — the dough will handle predictably and produce the crumb described above.

Absorption math for All-Purpose Flour at 72%

A recipe written for bread flour at 72% hydration, when substituted with 100% All-Purpose Flour, becomes 70% effective hydration (because All-Purpose Flour absorbs 3% less water). Shorter autolyse (20-30 min) — longer autolyses over-soften the gluten. Fewer stretch-and-folds (2-3 sets) to avoid tearing the weaker gluten structure. Best for beginner hydration range 65-70%.

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.
