Hydration & flour ratios

Hydration is the single number most bakers obsess over. Here's what it actually controls — and how flour protein content changes the math.

The hydration ladder

Hydration

60–65%

Crumb & handling

Dense, tight crumb. Easy to handle. Good for beginners.

Best for

Sandwich loaves, beginners.

Hydration

70–75%

Crumb & handling

Open, irregular crumb. Some shaping challenge.

Best for

Country loaves, everyday baking.

Hydration

78–82%

Crumb & handling

Very open, honeycombed. Slack, requires bench skill.

Best for

High-skill batards, ciabatta-style.

Hydration

85%+

Crumb & handling

Extremely open to foccacia-like. Bakes in a pan.

Best for

Pan loaves, focaccia, very experienced bakers.

Flour protein changes the math

Hydration percentages are always relative to flour absorption. A 75% dough with 11% protein flour (all-purpose) is noticeably wetter than 75% with 13% protein (strong bread flour) or 14%+ (high-gluten flour).

Whole wheat / rye

Bran absorbs water — add 5% more liquid for equivalent feel.

All-purpose (11%)

Lower protein = weaker gluten. Keep hydration ≤72% until your shaping is solid.

Strong bread flour (13%)

The reference point. Standard hydration calculations assume this baseline.
