Absorption math for Light Rye Flour at 55%

A recipe written for bread flour at 55% hydration, when substituted with 100% Light Rye Flour, becomes 57% effective hydration (because Light Rye Flour absorbs 3% more water). Handles closer to wheat than medium or dark rye — light stretch-and-folds are fine at low percentages. Keep the bulk ferment a touch shorter than an all-wheat dough; rye enzymes speed fermentation. Above ~40% rye, switch to no-knead rye handling (mix, rest, wet hands, tight banneton).

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.

The gear that makes the math work

A short, honest baking kit. The scale matters most — every weight on this page is in grams. The Dutch oven is what turns a good crumb into a great crust.

  • Digital kitchen scale (0.1 g)

    Baker's percentage is by weight, not volume — a 0.1 g scale is what makes the math on this page accurate.

  • Dutch oven / combo cooker

    Traps steam for the first bake phase — the single biggest factor in oven spring and a blistered, glossy crust.

  • Banneton proofing basket

    Wicks moisture and holds shape during the final proof, so high-hydration dough doesn't spread flat.

  • Bread lame

    A sharp lame scores clean ears — the cut that decides whether the loaf opens up or bursts at the side.

  • Bench scraper

    Steel scraper handles wet, sticky high-hydration dough without tearing the gluten you just built.

  • High-protein bread flour

    The math assumes ~12–14% protein. Real bread flour absorbs the hydration you calculate — all-purpose won't.
