Is 70% hydration right for Durum Semolina?
Durum Semolina's workable hydration range is 65–72%. Its absorption multiplier is 1.02× bread flour. At 70%, you are in the sweet spot — the dough will handle predictably and produce the crumb described above.
Absorption math for Durum Semolina at 70%
A recipe written for bread flour at 70% hydration, when substituted with 100% Durum Semolina, becomes 71% 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 70% hydration
Dough becomes visibly softer and stickier. Use wet hands or bench scraper. Starts requiring more careful handling to avoid degassing. Autolyse 45-60 min helps develop structure.

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.
