Why Whole Grain Dark Rye Flour (9.5% Protein / 1.75% Ash) Feels Firm at 75% (363g Water)

100% Whole Grain Dark Ryeβ€”Roggen Vollkornmehl (9.5% protein, 1.75% ash)β€”uses Secale cereale secalin proteins at 75% (363g water, 75.09%) where gluten cannot cross-link. Structure across 327g + 36g water (vs 375g / 77.3%) relies on pentosan gums (96% ceiling) at pH < 4.3. Under a 75% (75.09%) regime using 363g water (327g + 36g) and 11g salt, 500g Whole Grain Dark Rye Flour requires zero VWG below its 96% cap.

SWEET-SPOT & CEILING CALIBRATION: Using 363g main water (327g soak + 36g bassinage) on 500g Whole Grain Dark Rye Flour (9.5% protein, 1.75% ash) locks 75.09% (75%) with +21% headroom below 96% vs Caputo Tipo 00 Flour.

4-Step Autolyse, Bassinage & Coil-Fold Protocol for 500g Whole Grain Dark Rye Flour @ 75%

  1. Endosperm Swelling (Whole Grain Dark Rye Flour / 9.5% Prot): Combine 500g Whole Grain Dark Rye Flour and 327g water (65% soak) for 45 min.
  2. True-75% Calibration (363g W + 100g Levain): Incorporate 100g ripe culture, 11g salt, and 36g reserved water across 550g total flour (75.09%).
  3. Lamination & Coil Cadence (1.75% Ash): Perform 1 bench lamination and 3 coil folds at 30-min intervals on your 75% Whole Grain Dark Rye Flour dough.
  4. Overnight 38Β°F Retardation: Arrest fermentation at +50% rise, stitch in a breathable liner, chill 14 hrs, and bake 20m covered + 22m uncovered.

Common Scaling & Troubleshooting Questions (CONSERVATIVE)

Is Whole Grain Dark Rye Flour malted or unmalted for a 75% (363g water) sourdough?

In the Secale cereale Pentosan Matrix category (9.5% protein, 1.75% ash), 500g Whole Grain Dark Rye Flour hydrated with 363g water (75.09% / 75%) follows a 82%–90% sweet spot and 96% ceiling.

What happens if Whole Grain Dark Rye Flour goes 21% closer to its 96% limit at 75%?

At 75% (363g water, 75.09%), 500g Whole Grain Dark Rye Flour (9.5% protein) still holds a +21% buffer before reaching its 96% (478g water) ceiling.

How much salt is needed for 500g Whole Grain Dark Rye Flour and 100g starter at 75%?

Weigh 11.0g fine sea salt (2.0% of 550g total flour: 500g Whole Grain Dark Rye Flour + 50g starter flour) alongside 363g water (327g + 36g) to tighten the 9.5% protein matrix at 75.09% (75%).
