Is 95% hydration right for Whole Wheat Flour?
Whole Wheat Flour's workable hydration range is 75–85%. Its absorption multiplier is 1.075× bread flour. 95% is above 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 85%, or blend Whole Wheat Flour (40–60%) with bread flour for structural support.
Absorption math for Whole Wheat Flour at 95%
A recipe written for bread flour at 95% hydration, when substituted with 100% Whole Wheat Flour, becomes 102% effective hydration (because Whole Wheat Flour absorbs 7% more water). Extended autolyse (60-90 min) allows bran to fully hydrate and soften, improving gluten development. Warmer water (80-85°F) during autolyse accelerates this. Use at 15-30% of flour in blended doughs for flavor without overwhelming structure; use at 100% for true whole-grain loaves accepting denser crumb. Add 2% extra hydration beyond recipe baseline when substituting whole wheat.
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.
