70% Hydration Bread Flour

Is 70% hydration right for Bread Flour?

Bread Flour's workable hydration range is 65–78%. Its absorption multiplier is 1× bread flour. At 70%, you are in the sweet spot — the dough will handle predictably and produce the crumb described above.

Absorption math for Bread Flour at 70%

A recipe written for bread flour at 70% hydration, when substituted with 100% Bread Flour, becomes 70% 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 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.

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 70% exactly.

What Bread Flour gives you at 70%

At 70% hydration you can expect an open, custardy crumb with irregular holes and good chew. A medium dough: three to four sets of stretch-and-folds in the first two hours build the structure, and a light dusting of flour is enough for shaping. It handles predictably.
