How White Whole Wheat Flour behaves at each hydration

White whole wheat is milled from hard white wheat (not red). Same whole-kernel nutrition as red whole wheat but with a milder, sweeter flavor profile and slightly lighter crumb color. Protein is ~0.5% lower than red whole wheat, and absorption is ~1.5% less. Good gateway for bakers transitioning from refined flours. King Arthur's White Whole Wheat is the US reference. Excellent in 20-40% blends with bread flour for everyday sourdough that's more nutritious than 100% refined but less intense than 100% red whole wheat.

Substituting White Whole Wheat Flour for bread flour

Absorption multiplier: 1.060×. When substituting for bread flour, add about 6% more water. For example: a 75% bread-flour recipe becomes 80% when using 100% White Whole Wheat Flour.

The calculator below is pre-set to 77%. Adjust the slider to match your target. Salt and levain percentages are the flour-independent defaults (2.0% and 20%).

Technique at target hydration

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.

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.

The gear that makes the math work

A short, honest baking kit. The scale matters most — every weight on this page is in grams. The Dutch oven is what turns a good crumb into a great crust.
