Is 95% hydration right for Durum Semolina?

Durum Semolina's workable hydration range is 6572%. Its absorption multiplier is 1.02× bread flour. 95% is above Durum Semolina's typical range. The dough will be slack and may not hold shape in a free-form hearth loaf. Either reduce hydration to 72%, or blend Durum Semolina (40–60%) with bread flour for structural support.

Absorption math for Durum Semolina at 95%

A recipe written for bread flour at 95% hydration, when substituted with 100% Durum Semolina, becomes 97% 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 95% hydration

Only expert bakers attempt this reliably. Requires olive oil (5%) in dough, stand mixer to develop structure, oiled work surfaces, bench scrapers throughout. Cannot be free-form shaped.

Worked water math for a 500 g batch

Durum Semolina ingredient weights for 500 g flour at 95% hydration
Durum Semolina500 g (100%)
Water475 g (95%)
Salt10 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 95% exactly.

What Durum Semolina gives you at 95%

At 95% 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.
