Extreme 82% Hydration Sourdough (1000g Flour): 722g Base + 80g Bassinage (2-Loaf Batch)

Ciabatta-style 82% formula on 1000g flour (2024g batch) with 80g bassinage staging and -18g starter deduction.

Instant Lab Reference Verdict (Hydration × Flour Weight Formula)

In a 1000g flour formula at 82%, naive baker's math (820g water + 200g starter) overshoots to 83.6% (+1.6% above spec) across 1100g total flour. Setting your scale to 802g water (-18g deduction) and 22g salt in a 2024g batch locks True Total Hydration at 82.0% (target 82%).

Bassinage Mechanics for 1000g Flour at 82% Hydration (802g Water)

Introducing 200g ripe culture into 1000g flour contributes 100g degraded gluten and 100g organic-acid water, pushing an unadjusted 820g pour to 83.6% (+1.6% surge). Weighing 802g water (722g autolyse + 80g bassinage) and 22g salt across 1100g flour locks True Total Hydration at 82.0% (target 82%).

Farinograph torque on 1000g flour at 82% (802g main water + 100g starter water = 902g over 1100g flour) peaks when 722g water hydrates starch granules before 22g salt and 80g bassinage water arrive, balancing extreme stretch with supple recoil.

Double-Hydration (722g + 80g) Mixing Steps on 1000g Flour

  1. Pre-Ferment & 722g Autolyse (1000g Flour): Verify 200g levain is domed, then soak 1000g flour in 722g water for 40–50 min.
  2. Rubaud Emulsification (802g Total Main Water): Rubaud-mix 200g starter (100gF/100gW), 22g salt, and 80g reserved water into the 2024g mass (82%).
  3. Alveolar Structuring (82.0% True Moisture): Execute 4 coil folds spaced 30 min apart to manage extreme stretch on 1100g flour.
  4. Retardation & Scoring (2-Loaf Batch / 2024g): Preshape, tension-stitch into a rice-floured liner, chill 12–16 hrs at 38°F, and bake at 450°F.

Frequently Asked Questions for This Hydration × Flour Weight Formula Spec

How many loaves does 1000g flour at 82% hydration (2024g) make?

A 1000g flour formula with 802g water, 200g starter, and 22g salt produces 2024g total dough—ideal as 2-Loaf Batch at 82.0% (82%).

How much starter and salt go into 1000g flour at 82% hydration?

At 20% inoculation and 2% total-flour salt, combine 1000g flour with 200g active starter (100gF + 100gW), 802g water, and 22g salt (2% of 1100g total flour) for a 2024g batch.

How does 722g autolyse water improve a 1000g loaf at 82%?

Soaking 1000g flour in 722g water for 45 minutes before adding 200g acidic starter, 22g salt, and 80g water (802g total) builds supple elasticity across the 2024g dough.
