Is 70% hydration right for All-Purpose Flour?
All-Purpose Flour's workable hydration range is 60–72%. Its absorption multiplier is 0.97× bread flour. At 70%, you are in the sweet spot — the dough will handle predictably and produce the crumb described above.
Absorption math for All-Purpose Flour at 70%
A recipe written for bread flour at 70% hydration, when substituted with 100% All-Purpose Flour, becomes 68% 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 70% hydration
Dough becomes visibly softer and stickier. Use wet hands or bench scraper. Starts requiring more careful handling to avoid degassing. Autolyse 45-60 min helps develop structure.

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.
