Why Central Milling ABC+ Flour (11.5% Protein) Slumps at 78% (+1% Over 77% Cap)

Central Milling Organic ABC+ Flour (11.5% protein, 0.58% ash) is stone-and-roller milled in Utah for 78% (379g water, 78.0%) Tartine-style loaves from organic Hard Red Winter wheat and malted barley. Across a 341g autolyse and 38g bassinage (vs 390g / 80%), its high-polymer glutenin supports a 77% ceiling. Calibrating 500g Central Milling ABC+ Flour to 78% (78.0%) via 379g water (-11g deduction from 390g) preserves 70%–75% crumb elasticity.

GLUTEN FILM WEAKENING (78% vs 77% Max): Mixing 500g Central Milling ABC+ Flour (11.5% protein) with 379g water (78.0%) leaves 6g unabsorbed liquid (+1% over ceiling). Rescue tenacity by adding 3g Vital Wheat Gluten during the 341g autolyse or scaling water to 374g.

Gluten Conditioning Workflow: 500g Central Milling ABC+ Flour, 341g Soak + 38g Splash

  1. 90% Base Autolyse (500g Central Milling ABC+ Flour + 341g W): Hydrate 500g Central Milling ABC+ Flour with 341g water (withholding 38g of 379g) for 45 min.
  2. 10% Double-Hydration Mix (-11g Cut): Rubaud-mix 100g starter, 11g salt, and 38g water to lock 78.0% (78% vs 80%).
  3. Tenacity Conditioning (70–75% Sweet Spot): Apply 4 damp-hand folds every 30 min tailored to Central Milling ABC+ Flour (77% max).
  4. Banneton Tension & Steam Bake: Divide or preshape 500g Central Milling ABC+ Flour batch, rest 20 min, cold-retard overnight at 38°F, and score at 45°.

Key Baker's Math Questions (Absorption Status: OVER)

How does Central Milling ABC+ Flour's 0.58% ash content affect 78% sourdough?

In 500g Central Milling ABC+ Flour (11.5% protein, 0.58% mineral ash) hydrated with 379g water (78.0% / 78%), the 0.58% ash fraction buffers pH and sets its 77% absorption ceiling.

Can I substitute Marriage's Manitoba Strong Flour for Central Milling ABC+ Flour at 78% hydration?

Swapping 500g Central Milling ABC+ Flour (77% cap, 70%–75% sweet spot) for Marriage's Manitoba Strong Flour (88% cap, 14.9% protein) at 78% (379g water) shifts ceiling margin by 11%.

How much water should I hold back for bassinage with 500g Central Milling ABC+ Flour at 78%?

Out of 379g corrected water for 500g Central Milling ABC+ Flour at 78% (78.0%), mix 341g (90%) during the autolyse and trickle in 38g (10%) with 100g starter and 11g salt.
