Why King Arthur Bread Flour (12.7% Protein / 0.52% Ash) Feels Firm at 65% (308g Water)

King Arthur Unbleached Bread Flour (12.7% protein, 0.52% ash) is roller-milled for 65% (308g water) sourdough from unmalted US Hard Red wheat with high Alveograph P/L tenacity (65.09% true hydration). With zero malted barley amylase across a 277g autolyse and 31g bassinage, its starch resists liquefaction vs 325g (68.2%). Hydrating 500g King Arthur Bread Flour with 308g water and 100g starter to lock 65.09% (65% target, avoiding 68.2%) leaves 15% headroom under its 80% ceiling.

CONTROLLED EXTENSIBILITY WINDOW: Pairing 500g King Arthur Bread Flour (12.7% protein, 0.52% ash) with 308g water (-17g vs 325g / 68.2%) locks 65.09% (65%), preserving +15% reserve capacity under 80%.
