85% Hydration Bread Flour

Is 85% hydration right for Bread Flour?

Bread Flour's workable hydration range is 65–78%. Its absorption multiplier is 1× bread flour. 85% 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 85%

A recipe written for bread flour at 85% hydration, when substituted with 100% Bread Flour, becomes 85% 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 85% hydration

Pan-baked or stretched on floured surface — not bannetoned or shaped. Requires high-protein bread flour (or rye's pentosan structure). Advanced technique territory.

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 85% exactly.

What Bread Flour gives you at 85%

At 85% hydration you can expect a very open, glossy, holey crumb — the signature of a high-hydration hearth loaf. A very wet dough: minimal handling wins. Use wet hands and a bench scraper, coil or stitch folds only, a strong pre-shape, and a well-floured couche or banneton — this hydration rewards a light, confident touch and punishes over-working.
