Why Caputo Tipo 00 Flour (13% Protein / 0.50% Ash) Feels Firm at 62% (291g Water)
Caputo Tipo 00 Chef Flour (13.0% protein, 0.50% ash, W300–W320) is soft-milled in Naples for 62% (291g water, 62.0%) builds with ultra-fine granulation and low Alveograph P/L (0.55). Its intact starch binds less water during a 262g soak + 29g splash than 310g (65.5%), capping at 74%. At 62% extreme benchmark (291g main water locking 62.0% vs 65.5% apparent), Caputo Tipo 00 Flour (0.50% ash) demands 29g staged bassinage water.
CAPILLARY WATER BINDING (Caputo Tipo 00 Flour @ 62.0%): With 13% protein and 0.50% ash, 500g Caputo Tipo 00 Flour absorbs 291g corrected water (62% target, -19g from 310g) cleanly, sitting +12% inside its 74% limit (64%–70% sweet spot).
Recommended Mixing Strategy for Caputo Tipo 00 Flour at 62% (291g Water)
- Ash & Starch Hydration (0.50% Ash / 262g W): Whisk 262g water into 500g Caputo Tipo 00 Flour for 35 min.
- Starter & Salt Integration (291g Corrected W): Pinch 100g peaked levain (50gF/50gW), 11g sea salt, and 29g water into 500g Caputo Tipo 00 Flour (62.0%).
- Gluten Alignment (13% Protein @ 62%): Space 4 coil folds 30 min apart to manage [CONSERVATIVE] viscosity.
- Cold Proof & 450°F Bake: Shape tightly after +50% aliquot expansion, retard 12–16 hrs at 38°F, and bake in cast iron at 450°F.
