800g Flour at 62% Low-Hydration Sourdough: 466g Water, 160g Starter & 17.6g Salt (2-Loaf Batch)

Stiff 62% formula for 800g flour (1444g dough, 2-loaf batch), deducting 30g starter water from 496g.

Executive Baker's Math Summary (Hydration × Flour Weight Formula)

Across 880g combined flour (800g base + 80g from 160g starter), an unadjusted 496g water weight produces 576g total liquid or 65.5% (+3.5% surge). Restricting main water to 466g (-30g) with 17.6g salt (1444g dough) locks True Total Hydration at 62.05% (target 62%).

Why 62% Low-Hydration Sourdough (800g Flour / 466g Water) Holds Spring

Hydrating 800g flour with 496g water plus 160g starter forces 880g total flour to absorb 576g water (65.5%). Staging 419g autolyse water and 47g bassinage water (466g total, -30g deduction) with 17.6g salt in your 1444g dough locks True Total Hydration at 62.05% (target 62%).

At 62.05% true hydration (546g total water ÷ 880g flour), your 800g flour dough exhibits beginner friendly handling (1/5 stars). Cutting 30g from 496g down to 466g (419g + 47g) with 17.6g salt prevents serum weeping.

Step-by-Step Mixing & Folding Protocol for a 1444g Batch (800g @ 62%)

  1. 90% Water Autolyse (419g / 466g): Mix 800g unbleached flour with 419g water and rest covered 45 min to initiate glutenin linking.
  2. 10% Bassinage & Starter Addition (47g W + 160g Levain): Add 160g starter (80gF/80gW), 17.6g salt, and 47g water for 62.05% (62%) across 880g flour.
  3. Viscoelastic Folding (1444g Batch, Beginner Friendly): Complete 4 coil folds at 30-min intervals to balance low extensibility.
  4. Cold Fermentation & Bake (800g Base): Shape into a taut 2-loaf batch, chill 14 hrs at 38°F, and bake 42 min total at 450°F.

Cereal Chemistry & Bench Execution FAQs

Why is salt 17.6g instead of 16g for 800g flour at 62%?

True 2.0% salinity counts the 80g flour inside your 160g starter (800g + 80g = 880g total flour × 2% = 17.6g salt), stabilizing the 1444g loaf at 62.05% (62%).

How many loaves does 800g flour at 62% hydration (1444g) make?

A 800g flour formula with 466g water, 160g starter, and 17.6g salt produces 1444g total dough—ideal as 2-Loaf Batch at 62.05% (62%).

How much water do I need for 800g of flour at 62% hydration?

Multiplying 800g by 62% gives 496g apparent water, which drifts to 65.5% (+3.5%) with 160g starter. Weighing 466g main water (-30g cut) locks True Total Hydration at 62.05% (target 62%).
