Is 90% hydration right for Emmer Flour (Farro)?
Emmer Flour (Farro)'s workable hydration range is 65–75%. Its absorption multiplier is 0.95× bread flour. 90% is above Emmer Flour (Farro)'s typical range. The dough will be slack and may not hold shape in a free-form hearth loaf. Either reduce hydration to 75%, or blend Emmer Flour (Farro) (40–60%) with bread flour for structural support.
Absorption math for Emmer Flour (Farro) at 90%
A recipe written for bread flour at 90% hydration, when substituted with 100% Emmer Flour (Farro), becomes 86% effective hydration (because Emmer Flour (Farro) absorbs 5% less water). Medium autolyse (30-45 min). 2-3 gentle stretch-and-folds. Moderately extended bulk (similar to bread flour). Emmer tolerates retarded proofing well. Pair with 20-30% bread flour for structure support in free-form hearth loaves.
Technique at 90% hydration
Dough handling requires constant wet hands, bench scrapers, and oiled surfaces. Include 5% olive oil for lubrication. Pan-baked only. Expert-level technique.

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.
