450g Flour at 60% Low-Hydration Sourdough: 252g Water, 90g Starter & 9.9g Salt (1 Standard Loaf)
Stiff 60% formula for 450g flour (802g dough, 1 standard loaf), deducting 18g starter water from 270g.
Scaling a 450g sourdough build to 60% with 90g 1:1:1 levain means an unadjusted 270g water pour drifts to 63.6% (+3.6% excess) from 45g hidden liquid and 45g fermented flour. Weighing 252g main water (-18g offset) plus 9.9g sea salt locks True Total Hydration at 60.0% (target 60%) across a 802g loaf.

450g Flour at 60% Hydration: 2D Scale & Starter Sensitivity Matrix
System flour (495g) and total water (297g) mass-balance rows around 450g flour at 60% (60.0%).
| Batch & Seed Spec | Flour Breakdown | Levain Split | Corrected Water (60% Ref) | Salt & Dough Mass | Apparent vs Locked |
|---|---|---|---|---|---|
| 400g @ 58% (15% Seed) Smaller Loaf (-50g) | 400g + 30g = 430g (60%/450g ref) | 60g (30gF/30gW @ 100%) | 219g W (vs 232g app @ R1) | 8.6g salt (679g dough) | 60.9% drift → 57.91% (58% goal) |
| 450g @ 58% (18% Seed) Lower Moisture (-2%) | 450g + 45g = 495g (60%/450g ref) | 81g (45gF/36gW @ 80%) | 251g W (vs 261g app @ R2) | 9.9g salt (782g dough) | 60.0% drift → 57.98% (58% goal) |
| 450g @ 60% (20% Seed) [Calibrated Target] | 450g + 45g = 495g (60%/450g ref) | 90g (45gF/45gW @ 100%) | 252g W (vs 270g app @ R3) | 9.9g salt (792g dough) | 63.6% drift → 60.0% (60% goal) |

Why 60% Low-Hydration Sourdough (450g Flour / 252g Water) Holds Spring
Hydrating 450g flour with 270g water plus 90g starter forces 495g total flour to absorb 315g water (63.6%). Staging 227g autolyse water and 25g bassinage water (252g total, -18g deduction) with 9.9g salt in your 802g dough locks True Total Hydration at 60.0% (target 60%).
Because 45g starter flour inside 90g levain carries lactic proteolysis into 450g fresh flour, unadjusted 270g water (63.6%) causes slack tearing. Deducting 18g to 252g water (60.0%, 1/5 stickiness) keeps the 802g loaf inside the beginner friendly window.
Bench & Dutch Oven Protocol for 1 Standard Loaf (450g Flour @ 60% Hydration)
- Enzymatic Rest (450g Flour + 227g Water): Blend 227g water into 450g flour (holding back 25g of 252g) for 45 min.
- True-60% Calibration (-18g Deduction): Incorporate 90g starter, 9.9g sea salt, and 25g water to yield 802g dough at 60.0% (vs 63.6%).
- Tension Alignment (495g System Flour): Perform 4 damp-hand coil folds every 30 min tailored to 1/5 stickiness and high tenacity elasticity.
- Overnight Retard & Cast-Iron Bake (1 Standard Loaf): Terminate bulk at +50% rise, cold-proof at 38°F, score deeply, and bake at 450°F.
Key Baker's Math Questions (Strict True Hydration Water: 252g)
Why does 270g water make my 450g flour dough feel like 63.6%?
Your 90g of 100% starter adds 45g water and 45g flour, turning 270g water into 315g water over 495g flour (63.6%). Dropping 18g to 252g locks True Total Hydration at 60.0% (target 60%).
Is 60% hydration too wet for 450g of bread flour?
At 60% (252g water on 450g flour, 802g dough), the 60.0% formula sits comfortably inside standard 11.7%–12.7% protein flour limits (1/5 tack).
Can I scale this 450g / 60% formula down by 50g to 400g flour?
At 400g flour and 60% hydration (vs 450g / 252g water), use 80g starter and 224g corrected water.
