500g Flour at 60% Low-Hydration Sourdough: 280g Water, 100g Starter & 11g Salt (1 Standard Loaf)
Stiff 60% formula for 500g flour (891g dough, 1 standard loaf), deducting 20g starter water from 300g.
To bake 500g flour at 60% without suffering a 63.6% (+3.6%) soupier dough from 300g water and 100g starter, subtract 20g water. Combining 280g main water, 50g+50g levain, and 11g salt (891g total) locks True Total Hydration at 60.0% (target 60%).

True (60.0%) vs Apparent (63.6%) Matrix for 500g Flour
Stepwise levain inoculation (15%–25%) and hydration offsets for a 891g (1 Standard Loaf) batch using 500g flour.
| Batch & Seed Spec | Flour Breakdown | Levain Split | Corrected Water (60% Ref) | Salt & Dough Mass | Apparent vs Locked |
|---|---|---|---|---|---|
| 450g @ 58% (15% Seed) Mini Scale (-50g) | 450g + 34g = 484g (60%/500g ref) | 68g (34gF/34gW @ 100%) | 247g W (vs 261g app @ R1) | 9.7g salt (765g dough) | 61.0% drift → 58.06% (58% goal) |
| 500g @ 58% (18% Seed) Tighter Crumb (-2%) | 500g + 50g = 550g (60%/500g ref) | 90g (50gF/40gW @ 80%) | 279g W (vs 290g app @ R2) | 11.0g salt (869g dough) | 60.0% drift → 58.0% (58% goal) |
| 500g @ 60% (20% Seed) [Exact Spec] | 500g + 50g = 550g (60%/500g ref) | 100g (50gF/50gW @ 100%) | 280g W (vs 300g app @ R3) | 11.0g salt (880g dough) | 63.6% drift → 60.0% (60% goal) |
| 500g @ 62% (22% Seed) Airier Crumb (+2%) | 500g + 55g = 555g (60%/500g ref) | 110g (55gF/55gW @ 100%) | 289g W (vs 310g app @ R4) | 11.1g salt (899g dough) | 65.8% drift → 61.98% (62% goal) |
| 550g @ 62% (25% Seed) Boosted Scale (+50g) | 550g + 61g = 611g (60%/500g ref) | 138g (61gF/77gW @ 125%) | 302g W (vs 341g app @ R5) | 12.2g salt (990g dough) | 68.4% drift → 62.03% (62% goal) |

Why 60% Low-Hydration Sourdough (500g Flour / 280g Water) Holds Spring
In a 891g loaf built from 500g flour, 100g starter alters the solvent-to-solids ratio by injecting 50g water alongside 50g flour. Replacing the naive 300g water weight (63.6% true moisture) with 280g (-20g cut) and 11g salt locks True Total Hydration at 60.0% (target 60%).
Viscoelastic creep tests at 60% hydration (280g water + 100g starter on 500g flour) confirm high tenacity elastic recovery when 11g salt reinforces the 550g protein matrix and 28g bassinage water is emulsified after the 252g autolyse (891g dough).
Rheological Handling Guide (1/5 Tack) for 500g Flour at 60%
- Pre-Ferment & 252g Autolyse (500g Flour): Verify 100g levain is domed, then soak 500g flour in 252g water for 40–50 min.
- Rubaud Emulsification (280g Total Main Water): Rubaud-mix 100g starter (50gF/50gW), 11g salt, and 28g reserved water into the 891g mass (60%).
- Alveolar Structuring (60.0% True Moisture): Execute 4 coil folds spaced 30 min apart to manage low stretch on 550g flour.
- Retardation & Scoring (1 Standard Loaf / 891g): Preshape, tension-stitch into a rice-floured liner, chill 12–16 hrs at 38°F, and bake at 450°F.
Key Baker's Math Questions (Strict True Hydration Water: 280g)
How many loaves does 500g flour at 60% hydration (891g) make?
A 500g flour formula with 280g water, 100g starter, and 11g salt produces 891g total dough—ideal as 1 Standard Loaf at 60.0% (60%).
What is the true flour weight in a 500g flour + 100g starter dough at 60%?
Combining 500g main flour with 100g of 100% starter (50g flour + 50g water) yields 550g total system flour, paired with 330g total water (280g main + 50g starter) for 60.0% (60%).
How sticky is a 500g flour sourdough at 60% hydration (280g water)?
At 60.0% (target 60%) with 280g water and 100g starter on 500g flour, rheology scores 1/5 stars (Beginner Friendly) with low extensibility.
