Country 74% Sourdough Formula for 1000g Flour: 714g Water & 200g Levain (2-Loaf Batch)

True 74.0% vs 76.4% apparent breakdown for 1000g flour (1936g 2-loaf batch, -26g water cut).

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

Scaling a 1000g sourdough build to 74% with 200g 1:1:1 levain means an unadjusted 740g water pour drifts to 76.4% (+2.4% excess) from 100g hidden liquid and 100g fermented flour. Weighing 714g main water (-26g offset) plus 22g sea salt locks True Total Hydration at 74.0% (target 74%) across a 1936g loaf.

Open Crumb & Gluten Physics at 74% Hydration (1000g Flour + 714g Water)

Hydrating 1000g flour with 740g water plus 200g starter forces 1100g total flour to absorb 840g water (76.4%). Staging 643g autolyse water and 71g bassinage water (714g total, -26g deduction) with 22g salt in your 1936g dough locks True Total Hydration at 74.0% (target 74%).

Because 100g starter flour inside 200g levain carries lactic proteolysis into 1000g fresh flour, unadjusted 740g water (76.4%) causes slack tearing. Deducting 26g to 714g water (74.0%, 3/5 stickiness) keeps the 1936g loaf inside the moderate window.

Bench & Dutch Oven Protocol for 2-Loaf Batch (1000g Flour @ 74% Hydration)

  1. Stage-1 Hydration (643g of 714g Water): Whisk 643g water into 1000g base flour and cover for 45 min while 200g starter peaks.
  2. Stage-2 Double Hydration (+71g Splash & 22g Salt): Slap-and-fold 200g culture (100gF/100gW), 22g salt, and 71g water to lock 74.0% (74%).
  3. Gluten Organization (Moderate): Use damp fingers across 4 coil-fold sets to organize the 1936g (1100g total flour) matrix.
  4. Banneton Retard & Steam Bake (2-Loaf Batch): Shape tightly at +50% bulk volume, chill overnight at 38°F, and load into a 450°F Dutch oven.

Cereal Chemistry & Bench Execution FAQs

Why does 740g water make my 1000g flour dough feel like 76.4%?

Your 200g of 100% starter adds 100g water and 100g flour, turning 740g water into 840g water over 1100g flour (76.4%). Dropping 26g to 714g locks True Total Hydration at 74.0% (target 74%).

Is 74% hydration too wet for 1000g of bread flour?

At 74% (714g water + 200g starter on 1000g flour), use 12.7%+ bread flour and stage 71g bassinage water after a 643g autolyse to handle 3/5 stickiness.

Can I scale this 1000g / 74% formula down by 50g to 950g flour?

At 950g flour and 74% hydration (vs 1000g / 714g water), use 190g starter and 678g corrected water.
