Understanding Hydration: The Key to Texture

From 65% to 85% — what each hydration level does to crumb, crust, and handling.

Master Baker John Park2 min read

Hydration — the ratio of water to flour — has profound effects on your bread. Understanding it transforms your results.

What hydration is

Hydration = water weight ÷ flour weight, expressed as a percentage. 500g flour + 350g water = 70% hydration.

What each level does

Low (65–70%)

Easier to handle, less sticky. Tighter crumb, firmer texture. Best for beginners and sandwich bread.

Medium (72–78%)

Moderate stickiness, good balance. Open crumb with structure. The classic sourdough territory.

High (80–85%+)

Very sticky and challenging. Large irregular holes, rustic appearance. For experienced hands.

What changes hydration needs

Flour type — Bread flour absorbs more than all-purpose. Whole wheat absorbs significantly more. Rye drinks water aggressively.

Environment — High humidity = less water. Higher altitude often = more water.

Starter consistency — A thick (50%) starter requires more water in the dough than a liquid (100%) starter.

Adjusting in practice

Start conservative — lower hydration is easier to learn. It's easier to add water than remove it.

Watch for cues:

  • Right — slightly tacky, not sticky
  • Too dry — tears easily, feels tight
  • Too wet — won't hold shape, spreads

Technique by hydration

High hydration — wet hands, coil folds, bench scrapers, longer autolyse.

Low hydration — thorough mixing, traditional kneading, watch gluten development, longer fermentation.

Troubleshooting

Too sticky — resist adding flour. Use time and folding to develop structure. Wet your hands and tools. Consider whether this is normal for your hydration level.

Too stiff — gradually add water during mixing. Extend autolyse. Check flour age.

Mastering hydration takes time. Keep notes on what works for your flour and your kitchen.
