Is 95% hydration right for Bread Flour?

Bread Flour's workable hydration range is 6578%. Its absorption multiplier is 1× bread flour. 95% is above Bread Flour's typical range. The dough will be slack and may not hold shape in a free-form hearth loaf. Either reduce hydration to 78%, or blend Bread Flour (40–60%) with bread flour for structural support.

Absorption math for Bread Flour at 95%

A recipe written for bread flour at 95% hydration, when substituted with 100% Bread Flour, becomes 95% 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 95% hydration

Only expert bakers attempt this reliably. Requires olive oil (5%) in dough, stand mixer to develop structure, oiled work surfaces, bench scrapers throughout. Cannot be free-form shaped.

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.
