65% Hydration Whole Wheat Flour

Moderate cells, fairly uniform. Balanced chew — not dense, not fluffy. Classic sandwich bread territory.

Is 65% hydration right for Whole Wheat Flour?

Whole Wheat Flour's workable hydration range is 7585%. Its absorption multiplier is 1.075× bread flour. 65% is below Whole Wheat Flour's typical range. The dough will be stiff and hard to fully develop. Consider moving up to 75% for better extensibility.

Absorption math for Whole Wheat Flour at 65%

A recipe written for bread flour at 65% hydration, when substituted with 100% Whole Wheat Flour, becomes 70% 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 65% hydration

The traditional baguette hydration. Dough feels firm and shapes easily. Good starting hydration for hearth loaves without extreme-open-crumb expectations. Autolyse 30 min, 2-3 stretch-and-folds.

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.
