Is 65% hydration right for Medium Rye Flour?
Medium Rye Flour's workable hydration range is 80–95%. Its absorption multiplier is 1.08× bread flour. 65% is below Medium Rye Flour's typical range. The dough will be stiff and hard to fully develop. Consider moving up to 80% for better extensibility.
Absorption math for Medium Rye Flour at 65%
A recipe written for bread flour at 65% hydration, when substituted with 100% Medium Rye Flour, becomes 70% effective hydration (because Medium Rye Flour absorbs 8% more water). Do NOT knead rye dough (tears pentosan structure). Mix to incorporate, then rest. Very short bulk ferment (2-3 hours at 76°F) — rye ferments fast. Wet hands for shaping. Use a pan or tight banneton. Bake at higher initial temp (500°F) for 15 minutes, then reduce. Internal temp 205-210°F for doneness.
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
| Medium Rye 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 Medium Rye 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.

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.
