Whole Wheat Flour
1.075× absorption · 13.00–14.00% protein · hydration 75–85%
For sourdough, Whole Wheat Flour works best at 75–85% hydration. With 13.00–14.00% protein, it absorbs about 7% more water than standard bread flour.

What is Whole Wheat Flour?
Whole wheat flour contains the entire wheat kernel — bran, germ, and endosperm. Bran absorbs ~7.5% more water than refined flour, and the sharp bran particles cut through gluten strands, reducing effective gluten structure. Protein is higher by weight (13-14%) but functional gluten is lower. Result: whole wheat needs higher hydration (typically 80%+) and produces a denser, more flavorful crumb. WSU Bread Lab research shows hard red winter wheat varieties (Yecora Rojo, Warthog) mill into premium whole wheat for sourdough. King Arthur's Traditional Whole Wheat is a reliable reference.
How do you bake with Whole Wheat Flour?
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.
What hydration % for Whole Wheat Flour?
Baker's-percentage workable range: 75% — 85%. Absorption is 1.075× bread-flour baseline, so recipes written for bread flour need 7% more water when substituting Whole Wheat Flour.

Whole Wheat Flour at every hydration level
Whole Wheat Flour usually works between 75% and 85% hydration — drier gives a stiffer dough, wetter a slacker one. Tap a level for the technique, the absorption math and a calculator set to it.
