Is 70% hydration right for Whole Wheat Flour?
Whole Wheat Flour's workable hydration range is 75–85%. Its absorption multiplier is 1.075× bread flour. 70% 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 70%
A recipe written for bread flour at 70% hydration, when substituted with 100% Whole Wheat Flour, becomes 75% 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 70% hydration
Dough becomes visibly softer and stickier. Use wet hands or bench scraper. Starts requiring more careful handling to avoid degassing. Autolyse 45-60 min helps develop structure.
Worked water math for a 500 g batch
| Whole Wheat Flour | 500 g (100%) |
| Water | 350 g (70%) |
| Salt | 10 g (2%) |
Add your levain on top of these weights; the calculator below subtracts the flour and water it already contributes so the bench numbers land at 70% exactly.
What Whole Wheat Flour gives you at 70%
At 70% hydration you can expect an open, custardy crumb with irregular holes and good chew. A medium dough: three to four sets of stretch-and-folds in the first two hours build the structure, and a light dusting of flour is enough for shaping. It handles predictably.
Whole Wheat Flour at 70% — FAQ
How much water do I use for Whole Wheat Flour at 70% hydration?
Multiply the flour weight by 0.7. For a 500 g batch of Whole Wheat Flour that's 350 g water, plus about 10 g salt (2%). Whole Wheat Flour absorbs 1.075× as much water as white bread flour, so it will feel a touch stiffer than the 70% number suggests.
Is 70% hydration right for Whole Wheat Flour?
70% is below Whole Wheat Flour's usual 75–85% range — the dough will be stiff and hard to develop. Move up toward 75% for better extensibility.
What crumb will Whole Wheat Flour at 70% give me?
Expect an open, custardy crumb with irregular holes and good chew. Medium cells with some larger bubbles. Noticeable holes appearing. Chewy, moist, balanced.
Is Whole Wheat Flour at 70% beginner-friendly?
This hydration is rated intermediate. A medium dough: three to four sets of stretch-and-folds in the first two hours build the structure, and a light dusting of flour is enough for shaping. It handles predictably.
Calculator pre-set to 70%
Weights below assume 100% Whole Wheat Flour. For blends, use the main calculator on a recipe page.

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.
