72% Hydration Spelt Flour

Is 72% hydration right for Spelt Flour?

Spelt Flour's workable hydration range is 60–70%. Its absorption multiplier is 0.96× bread flour. 72% is above Spelt Flour's typical range. The dough will be slack and may not hold shape in a free-form hearth loaf. Either reduce hydration to 70%, or blend Spelt Flour (40–60%) with bread flour for structural support.

Absorption math for Spelt Flour at 72%

A recipe written for bread flour at 72% hydration, when substituted with 100% Spelt Flour, becomes 69% effective hydration (because Spelt Flour absorbs 4% less water). Short autolyse (20-30 min max). Gentle stretch-and-folds (2 sets). Shorter bulk ferment (15-20% less time than bread flour). Spelt over-proofs quickly — watch for signs and shape slightly underproofed. Cold retard is essential for handling.

Technique at 72% hydration

Dough requires strong gluten development (3-4 stretch-and-folds or coil folds). Shaping benefits from cold retard. Handle with wet hands or flour-dusted bench scraper.

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 72% exactly.

What Spelt Flour gives you at 72%

At 72% hydration you can expect an open, custardy crumb with irregular holes and good chew. A slack, sticky dough: work with wet hands, use coil folds rather than aggressive stretches, give a full bench rest after pre-shaping, and shape decisively — hesitation lets it spread.

Spelt Flour at every hydration level

Spelt Flour usually works between 60% and 70% hydration — drier gives a stiffer dough, wetter a slacker one. Tap a level for the technique, the absorption math and a calculator set to it.
