Is 85% hydration right for White Whole Wheat Flour?
White Whole Wheat Flour's workable hydration range is 72–82%. Its absorption multiplier is 1.06× bread flour. 85% is above White Whole Wheat Flour's typical range. The dough will be slack and may not hold shape in a free-form hearth loaf. Either reduce hydration to 82%, or blend White Whole Wheat Flour (40–60%) with bread flour for structural support.
Absorption math for White Whole Wheat Flour at 85%
A recipe written for bread flour at 85% hydration, when substituted with 100% White Whole Wheat Flour, becomes 90% effective hydration (because White Whole Wheat Flour absorbs 6% more water). Same autolyse approach as red whole wheat (60-90 min) but slightly shorter. Pairs well with bread flour at 25-30% whole grain for balanced loaves. Increase hydration by 1.5% when substituting for refined bread flour.
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.
Worked water math for a 500 g batch
| White Whole Wheat Flour | 500 g (100%) |
| Water | 425 g (85%) |
| 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 85% exactly.
What White Whole Wheat 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.

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.
