Why Bob's Red Mill Bread Flour (12.5% Protein / 0.55% Ash) Feels Firm at 65% (308g Water)

Bob's Red Mill Artisan Bread Flour (12.5% protein, 0.55% ash) pairs hard red wheat at 65% (308g water, 65.09%) with diastatic malted barley, boosting amylase maltose cleavage during a 277g autolyse. Because enzymatic dextrin softening accelerates near 68.2% (325g water), stage 31g bassinage water carefully. Under a 65% (65.09%) regime using 308g water (277g + 31g) and 11g salt, 500g Bob's Red Mill Bread Flour requires zero VWG below its 78% cap.

OPTIMAL STARCH-PROTEIN HYDRATION: For 500g Bob's Red Mill Bread Flour (US Malted Hard Red Wheat, 12.5% protein, 0.55% ash), 308g main water and 11g salt locks 65.09% (65%), avoiding 68.2% apparent drift while keeping +13% safety headroom below 78%.
