Is 75% hydration right for White Whole Wheat Flour?

White Whole Wheat Flour's workable hydration range is 7282%. Its absorption multiplier is 1.06× bread flour. At 75%, you are in the sweet spot — the dough will handle predictably and produce the crumb described above.

Absorption math for White Whole Wheat Flour at 75%

A recipe written for bread flour at 75% hydration, when substituted with 100% White Whole Wheat Flour, becomes 80% 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 75% hydration

The sweet spot for most hearth sourdough. Requires confident stretch-and-folds (3-4 sets). Wet hands essential for shaping. Cold retard improves handling and ear development during scoring.

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.
