Autolyse Calculator

Autolyse is the flour + water rest before adding salt and levain. The table below shows the water weights for common flour amounts at 70-85% hydration targets.

Autolyse water by flour weight

Use 90% of total recipe water for autolyse; reserve 10% for incorporating salt and levain afterward. Mix flour + autolyse water, rest, then add remaining water + salt + levain.

How long to autolyse?

  • Bread flour: 30-45 min. Extends gluten, reduces mix time.
  • Whole wheat: 60-90 min. Bran needs time to hydrate.
  • Rye (any): Skip autolyse. Mix once and rest; autolyse damages rye structure.
  • Spelt / einkorn: 15-20 min max. Ancient-wheat gluten degrades quickly.
  • Type 00: 15-20 min. Fine grind hydrates fast.

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 + bench scraper

    A sharp lame scores clean ears; a steel bench scraper handles wet, sticky dough without tearing the gluten.

  • High-protein bread flour

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

  • Danish dough whisk

    Mixes shaggy, high-hydration dough in seconds without the gluey mess of a spoon or your hands.

The numbers here are the what; a good baking book is the why. An Audible trial gets you any title free — Michael Pollan’s Cooked(the “Air” chapter is the best story ever told about why bread rises) is a perfect first listen.
