Absorption math for Durum Semolina at 65%

A recipe written for bread flour at 65% hydration, when substituted with 100% Durum Semolina, becomes 66% effective hydration (because Durum Semolina absorbs 2% more water). Long autolyse (60+ min) — durum is slow to hydrate fully. Firm dough: 68-72% hydration max. Use coil folds rather than stretch-and-folds. Shape with wet hands. Excellent for pan di Altamura-style boule shaping.

Technique at 65% hydration

The traditional baguette hydration. Dough feels firm and shapes easily. Good starting hydration for hearth loaves without extreme-open-crumb expectations. Autolyse 30 min, 2-3 stretch-and-folds.

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.
