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.
