Is 65% hydration right for High-Extraction Flour?
High-Extraction Flour's workable hydration range is 72–82%. Its absorption multiplier is 1.03× bread flour. 65% is below High-Extraction Flour's typical range. The dough will be stiff and hard to fully develop. Consider moving up to 72% for better extensibility.
Absorption math for High-Extraction Flour at 65%
A recipe written for bread flour at 65% hydration, when substituted with 100% High-Extraction Flour, becomes 67% effective hydration (because High-Extraction Flour absorbs 3% more water). Autolyse 45-60 min. 3-4 stretch-and-folds. Supports 78-80% hydration reliably. Excellent base for country-loaf-style hearth breads.
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.
Worked water math for a 500 g batch
| High-Extraction Flour | 500 g (100%) |
| Water | 325 g (65%) |
| 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 65% exactly.
What High-Extraction Flour gives you at 65%
At 65% hydration you can expect a moderately open, structured crumb with a crisp crust. 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.
High-Extraction Flour at 65% — FAQ
How much water do I use for High-Extraction Flour at 65% hydration?

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.
