Italian Type 00 Flour

Italian Type 00 is the finest-ground wheat flour category in the Italian classification system. Low ash content (0.45% max), very fine particle size, protein typically 11-12.5% for pizza and 13-14% for bread variants. Caputo's Pizzeria 00 (11-12%) is the global reference for Neapolitan pizza dough. Caputo Pizza Napoletana Cuoco (13-13.5%) is the bread-focused variant. Absorption is marginally higher than bread flour (1%) due to fine grind. Optimal for pizza (60-65% hydration), focaccia (75-80%), and sandwich loaves (65-68%).

All-Purpose Flour

All-purpose flour (AP) sits between cake flour and bread flour in protein content. At 10.5-11.7% protein, it produces softer sourdough with more tender crumb but less oven spring than bread flour. Absorption is ~3% lower than bread flour baseline. King Arthur's AP is the US reference (11.7% protein); Gold Medal and Pillsbury run slightly lower (10.5-11%). Use AP when you want a softer hearth loaf, a sandwich-style sourdough pan loaf, or when blending into enriched doughs like brioche. AP absorbs less water — recipes designed for bread flour need hydration reduced by ~3% when substituting AP.

Substitution math

When substituting Italian Type 00 Flour for All-Purpose Flour in a recipe, adjust hydration by about 4% — add more water because Italian Type 00 Flour absorbs more than All-Purpose Flour.
