Exact 68% Sourdough Ratio for 600g Flour: 389g Water vs 408g Apparent (1 Standard Loaf)
Baker's math for 600g flour at 68% (1122g dough, 1 standard loaf): 389g corrected water vs 70.9% drift.
Target 68% hydration on 600g flour requires accounting for 120g levain (60g flour / 60g water); otherwise 408g water yields 70.9% (+2.9% jump). Pouring 389g water (350g base + 39g splash) and 13.2g salt for a 1122g dough locks True Total Hydration at 68.03% (target 68%).

True 68.03% vs 70.9% Apparent Hydration on 600g Flour (120g Starter)
Introducing 120g ripe culture into 600g flour contributes 60g degraded gluten and 60g organic-acid water, pushing an unadjusted 408g pour to 70.9% (+2.9% surge). Weighing 389g water (350g autolyse + 39g bassinage) and 13.2g salt across 660g flour locks True Total Hydration at 68.03% (target 68%).
Farinograph torque on 600g flour at 68% (389g main water + 60g starter water = 449g over 660g flour) peaks when 350g water hydrates starch granules before 13.2g salt and 39g bassinage water arrive, balancing balanced stretch with balanced recoil.
Double-Hydration (350g + 39g) Mixing Steps on 600g Flour
- Stage-1 Hydration (350g of 389g Water): Whisk 350g water into 600g base flour and cover for 45 min while 120g starter peaks.
- Stage-2 Double Hydration (+39g Splash & 13.2g Salt): Slap-and-fold 120g culture (60gF/60gW), 13.2g salt, and 39g water to lock 68.03% (68%).
- Gluten Organization (Beginner Friendly): Use damp fingers across 4 coil-fold sets to organize the 1122g (660g total flour) matrix.
- Banneton Retard & Steam Bake (1 Standard Loaf): Shape tightly at +50% bulk volume, chill overnight at 38°F, and load into a 450°F Dutch oven.
