Is 55% hydration right for Organic Bread Flour?

Organic Bread Flour's workable hydration range is 6477%. Its absorption multiplier is 0.99× bread flour. 55% is below Organic Bread Flour's typical range. The dough will be stiff and hard to fully develop. Consider moving up to 64% for better extensibility.

Absorption math for Organic Bread Flour at 55%

A recipe written for bread flour at 55% hydration, when substituted with 100% Organic Bread Flour, becomes 54% effective hydration (because Organic Bread Flour absorbs 1% less water). Same as conventional bread flour but allow 2-3% more proofing time (slightly weaker gluten on some batches). Autolyse 45-60 min. 3-4 stretch-and-folds.

Technique at 55% hydration

Stiff dough, easy to handle. Use stand mixer for enriched versions. Low-hydration doughs tolerate mistakes well — good starting point for new bakers. Appropriate for pan-shaped loaves, enriched breads, and styles requiring dense texture like bagels and pretzels.

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.
