Is 75% hydration right for Bread Flour?
Bread Flour's workable hydration range is 65–78%. Its absorption multiplier is 1× bread flour. At 75%, you are in the sweet spot — the dough will handle predictably and produce the crumb described above.
Absorption math for Bread Flour at 75%
A recipe written for bread flour at 75% hydration, when substituted with 100% Bread Flour, becomes 75% effective hydration (because Bread Flour matches bread flour absorption). Autolyse 30-60 minutes with water at target dough temperature before adding levain and salt. For 75-80% hydration, add 3-4 sets of stretch-and-folds over the first 2 hours of bulk. Higher hydration (82%+) benefits from coil folds instead of stretch-and-folds. Shape cold (after overnight retard) for easier handling and better ear.
Technique at 75% hydration
The sweet spot for most hearth sourdough. Requires confident stretch-and-folds (3-4 sets). Wet hands essential for shaping. Cold retard improves handling and ear development during scoring.
Worked water math for a 500 g batch
| Bread Flour | 500 g (100%) |
| Water | 375 g (75%) |
| Salt | 10 g (2%) |
Add your levain on top of these weights; the calculator below subtracts the flour and water it already contributes so the bench numbers land at 75% exactly.
What Bread Flour gives you at 75%
At 75% hydration you can expect an open, custardy crumb with irregular holes and good chew. A slack, sticky dough: work with wet hands, use coil folds rather than aggressive stretches, give a full bench rest after pre-shaping, and shape decisively — hesitation lets it spread.

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.
