700g Flour at 65% Low-Hydration Sourdough: 431g Water, 140g Starter & 15.4g Salt (2-Loaf Batch)
Stiff 65% formula for 700g flour (1286g dough, 2-loaf batch), deducting 24g starter water from 455g.
To bake 700g flour at 65% without suffering a 68.2% (+3.2%) soupier dough from 455g water and 140g starter, subtract 24g water. Combining 431g main water, 70g+70g levain, and 15.4g salt (1286g total) locks True Total Hydration at 65.06% (target 65%).

True (65.06%) vs Apparent (68.2%) Matrix for 700g Flour
Pre-computed gram weights around 700g main flour where 431g water locks True Total Hydration at 65.06% (target 65%).
| Batch & Seed Spec | Flour Breakdown | Levain Split | Corrected Water (65% Ref) | Salt & Dough Mass | Apparent vs Locked |
|---|---|---|---|---|---|
| 650g @ 63% (15% Seed) Smaller Loaf (-50g) | 650g + 49g = 699g (65%/700g ref) | 98g (49gF/49gW @ 100%) | 391g W (vs 410g app @ R1) | 14.0g salt (1139g dough) | 65.7% drift → 62.95% (63% goal) |
| 700g @ 63% (18% Seed) Lower Moisture (-2%) | 700g + 70g = 770g (65%/700g ref) | 126g (70gF/56gW @ 80%) | 429g W (vs 441g app @ R2) | 15.4g salt (1255g dough) | 64.5% drift → 62.99% (63% goal) |
| 700g @ 65% (20% Seed) [Calibrated Target] | 700g + 70g = 770g (65%/700g ref) | 140g (70gF/70gW @ 100%) | 431g W (vs 455g app @ R3) | 15.4g salt (1271g dough) | 68.2% drift → 65.06% (65% goal) |
| 700g @ 67% (22% Seed) Higher Moisture (+2%) | 700g + 77g = 777g (65%/700g ref) | 154g (77gF/77gW @ 100%) | 444g W (vs 469g app @ R4) | 15.5g salt (1298g dough) | 70.3% drift → 67.05% (67% goal) |
| 750g @ 67% (25% Seed) Larger Batch (+50g) | 750g + 84g = 834g (65%/700g ref) | 188g (84gF/104gW @ 125%) | 455g W (vs 503g app @ R5) | 16.7g salt (1393g dough) | 72.8% drift → 67.03% (67% goal) |

Why 65% Low-Hydration Sourdough (700g Flour / 431g Water) Holds Spring
Unadjusted baker's percentages treat 140g starter as a weightless additive on 700g flour, causing 455g water to pool at 68.2% (+3.2% excess over 65%). Accounting for 70g starter flour and 70g starter water via 431g main water (-24g) locks True Total Hydration at 65.06% (target 65%).
Farinograph torque on 700g flour at 65% (431g main water + 70g starter water = 501g over 770g flour) peaks when 388g water hydrates starch granules before 15.4g salt and 43g bassinage water arrive, balancing low stretch with high tenacity recoil.
Execution Schedule: 700g Flour, 431g Water & 140g Starter (65.06%)
- Pre-Ferment & 388g Autolyse (700g Flour): Verify 140g levain is domed, then soak 700g flour in 388g water for 40–50 min.
- Rubaud Emulsification (431g Total Main Water): Rubaud-mix 140g starter (70gF/70gW), 15.4g salt, and 43g reserved water into the 1286g mass (65%).
- Alveolar Structuring (65.06% True Moisture): Execute 4 coil folds spaced 30 min apart to manage low stretch on 770g flour.
- Retardation & Scoring (2-Loaf Batch / 1286g): Preshape, tension-stitch into a rice-floured liner, chill 12–16 hrs at 38°F, and bake at 450°F.
Cereal Chemistry & Bench Execution FAQs
Why does unadjusted 455g water cause a +3.2% surge on 700g flour at 65%?
Because 65% is below 100% starter hydration, 140g starter (70gW / 70gF) raises 455g water to 525g over 770g flour (68.2%). Cutting 24g to 431g locks 65.06%.
What is the true flour weight in a 700g flour + 140g starter dough at 65%?
Combining 700g main flour with 140g of 100% starter (70g flour + 70g water) yields 770g total system flour, paired with 501g total water (431g main + 70g starter) for 65.06% (65%).
Why does 455g water make my 700g flour dough feel like 68.2%?
Your 140g of 100% starter adds 70g water and 70g flour, turning 455g water into 525g water over 770g flour (68.2%). Dropping 24g to 431g locks True Total Hydration at 65.06% (target 65%).
