Is 80% hydration right for Italian Type 00 Flour?

Italian Type 00 Flour's workable hydration range is 5868%. Its absorption multiplier is 1.01× bread flour. 80% is above Italian Type 00 Flour's typical range. The dough will be slack and may not hold shape in a free-form hearth loaf. Either reduce hydration to 68%, or blend Italian Type 00 Flour (40–60%) with bread flour for structural support.

Absorption math for Italian Type 00 Flour at 80%

A recipe written for bread flour at 80% hydration, when substituted with 100% Italian Type 00 Flour, becomes 81% effective hydration (because Italian Type 00 Flour absorbs 1% more water). Minimal autolyse (15-20 min) — fine grind hydrates quickly. For Neapolitan pizza: 60-62% hydration, 24-48h cold bulk, short proof, extreme heat bake. For bread: treat like AP or bread flour depending on protein spec.

Technique at 80% hydration

Dough is sticky and slack. Requires 4+ coil folds. Wet hands throughout all handling. Shape only after cold retard. Free-form shaping becomes difficult — consider pan shapes.

How the math works

Total water = flour × hydration %. Your levain contributes 50 g flour + 50 g water — both count toward the totals. You add only the remainder as fresh flour and water.

Salt % is computed on total flour weight, not final-dough flour.
