Bread Hydration (Lean Dough)

100%

Flour (bread flour or AP) — Higher-protein bread flour (12–13% protein) handles the full range; AP flour works at the lower end

60–65%

Water — Cold water slows fermentation; room-temperature water is standard for same-day bakes

1.8–2%

Salt — Added after autolyse if used; strengthens gluten and moderates yeast

0.5–1%

Instant yeast — Lower for long-ferment; higher for a single same-day rise

0–3%

Optional: olive oil or butter — Tiny fat additions soften crumb without crossing into enriched-dough territory

1. Combine flour and 90% of water; rest 20–30 minutes (autolyse) to hydrate flour evenly. 2. Add yeast, salt, and remaining water; mix until smooth and developed. 3. Bulk ferment at room temperature 1–2 hours with periodic folds, or overnight in the refrigerator. 4. Shape with confidence — at 60–65% hydration the dough holds its form without sticking excessively. 5. Proof in a loaf pan or on a floured couche; bake in a hot oven (220–230 °C / 425–450 °F) ideally with steam.

• Use kitchen scales — off-by-5% on a bathroom scale shifts hydration enough to noticeably change crumb structure.
• Flour protein content changes effective hydration: high-gluten flour (13–14%) can absorb 2–4% more water than all-purpose at the same 'feel.'
• Water temperature matters as much as quantity: target a final dough temperature of 24–26 °C (75–79 °F) — use the DDT formula (desired dough temp × 3) minus room and flour temperatures to find the correct water temp.
• Autolyse (resting flour and water before adding salt and yeast) markedly improves gluten development at 60–65% hydration, reducing total mixing time.
• If the dough tears rather than stretches, it is under-hydrated or under-developed, not necessarily too stiff — check mixing time before adding water.
• A properly hydrated lean dough passes the windowpane test: a small piece stretched thin should be translucent without tearing.

• 55–59% (stiff dough)

  Used for bagels, pretzels, and some rye breads; chewy, dense crumb; requires more mechanical mixing to develop gluten

• 66–74% (mid-range)

  Produces more open crumb; requires some bench skill but manages without special technique; typical for everyday sourdough loaves

• 75–85% (high hydration)

  Open, irregular crumb; dough is very slack; demands wet-hand technique, bench scraper, and banneton proofing — see Sourdough Hydration entry

• Whole wheat adjustment

  Whole wheat absorbs more water; add 5% water per 10% whole-wheat substitution to maintain the same handling feel

• Baker's Percentage System

  Hydration is always expressed as a baker's percentage with flour as 100%

• Sourdough Hydration (65–85%)

  The higher-hydration extension of this range for open-crumb loaves

• Salt to Flour Ratio in Bread (1.8–2.2%)

  Salt percentage pairs with hydration in every lean bread formula

• Pizza Dough Hydration

  Neapolitan pizza sits at 58–62%, the low end of this range
