Why 65% (308g Water) Is the Sweet Spot for German Type 550 Flour (11.2% Protein)
German Weizenmehl Type 550 (11.2% protein, 0.55% ash) is classified under DIN 10355 mineral standards and tested at 65% (308g water, 65.09%) on continental winter wheat (0.59 absorption). Splitting 277g autolyse from 31g bassinage (avoiding 325g / 68.2%) respects its 69% ceiling. Calibrating 500g German Type 550 Flour to 65% (65.09%) via 308g water (-17g deduction from 325g) preserves 62%–67% crumb elasticity.
DISULFIDE CROSS-LINK INTEGRITY: Staging 277g autolyse water and 31g bassinage water (308g total) on 500g German Type 550 Flour (11.2% protein, 0.55% ash) locks 65.09% (65%) with a +4% buffer under its 69% ceiling.
4-Step Autolyse, Bassinage & Coil-Fold Protocol for 500g German Type 550 Flour @ 65%
- Autolyse Soak (German Type 550 Flour @ 277g W): Mix 500g German Type 550 Flour (11.2% protein) with 277g water for 40 min.
- Levain & 31g Bassinage (308g Total W): Dimple 100g starter and 11g salt with 31g water to lock 65.09% (65%).
- Rheological Folds (DACH / Central Europe DIN 10355): Execute 3 stretch-and-folds every 45 min vs 69% cap.
- Preshape & 38°F Retard (German Type 550 Flour): Bench rest 25 min at +50% bulk rise, stitch into a rice-floured banneton, and chill 14 hrs at 38°F.
