Absorption math for Italian Type 00 Flour at 82%
A recipe written for bread flour at 82% hydration, when substituted with 100% Italian Type 00 Flour, becomes 83% 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 82% hydration
Dough is nearly batter-like. Hand-stretch on heavily floured surface; cut into rectangles with bench scraper. No shaping, no slashing. Bake on stone with initial steam.
Worked water math for a 500 g batch
| Italian Type 00 Flour | 500 g (100%) |
| Water | 410 g (82%) |
| Salt | 10 g (2%) |
Add your levain on top of these weights; the calculator below subtracts the flour and water it already contributes so the bench numbers land at 82% exactly.
What Italian Type 00 Flour gives you at 82%
At 82% hydration you can expect a very open, glossy, holey crumb — the signature of a high-hydration hearth loaf. A very wet dough: minimal handling wins. Use wet hands and a bench scraper, coil or stitch folds only, a strong pre-shape, and a well-floured couche or banneton — this hydration rewards a light, confident touch and punishes over-working.

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.
