Is 78% hydration right for Emmer Flour (Farro)?
Emmer Flour (Farro)'s workable hydration range is 65–75%. Its absorption multiplier is 0.95× bread flour. 78% 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 78%
A recipe written for bread flour at 78% hydration, when substituted with 100% Emmer Flour (Farro), becomes 74% 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 78% hydration
Upper range of 'standard' hearth hydration. Benefits from high-extraction flour which tolerates the hydration. Use coil folds instead of stretch-and-folds to build structure without deflating. Cold retard mandatory.

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.
