Is 70% hydration right for Organic Bread Flour?
Organic Bread Flour's workable hydration range is 64–77%. Its absorption multiplier is 0.99× bread flour. At 70%, you are in the sweet spot — the dough will handle predictably and produce the crumb described above.
Absorption math for Organic Bread Flour at 70%
A recipe written for bread flour at 70% hydration, when substituted with 100% Organic Bread Flour, becomes 69% 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 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.
