Understanding Dough Hydration: The Key to Better Bread

If you’ve ever dived into the world of bread-making, you’ve likely heard the term dough hydration. But what exactly does it mean, and why does it play such a crucial role in achieving the perfect loaf?

Whether you’re baking a simple sandwich bread, an artisan sourdough, or a rustic ciabatta, hydration is one of the most important factors that determines your dough’s texture, handling, and final crumb structure.

Let’s break it down in a simple, easy-to-understand way.

What Is Dough Hydration?

Dough hydration refers to the percentage of water in a dough relative to the amount of flour. It is always calculated by weight, not volume, because weight provides accuracy—unlike measuring cups, which can vary depending on how flour is packed.

The formula is straightforward:

(Water weight ÷ Flour weight) × 100 = Hydration percentage

Examples of Dough Hydration:

  • 500g flour + 250g water → 50% hydration (Firmer dough, holds its shape well)
  • 500g flour + 340g water → 68% hydration (Soft, slightly sticky dough, common for artisan loaves)
  • 500g flour + 400g water → 80% hydration (Very wet dough, produces an open crumb like ciabatta)

Hydration levels impact dough consistency, fermentation, gluten development, and the final texture of the bread.

Why Does Hydration Matter?

Hydration directly affects how dough behaves during mixing, shaping, and baking. Different hydration levels lead to different types of bread:

Low Hydration (50%–60%)

  • Firm, dense, and easy to handle
  • Holds shape well, with a tight crumb
  • Used for bagels, sandwich bread, and pizza dough

Medium Hydration (65%–75%)

  • More extensible and slightly sticky
  • Yields a balanced, soft crumb with good structure
  • Ideal for artisan bread, dinner rolls, and soft sandwich loaves

High Hydration (80%–100%)

  • Very wet and sticky, difficult to shape
  • Requires stretch-and-fold techniques instead of kneading
  • Produces an open, airy crumb with large holes
  • Used for ciabatta, focaccia, and rustic sourdough

How Does Hydration Affect Dough Handling?

  • Lower hydration dough is easy to shape and knead but results in a denser crumb.
  • Higher hydration dough is sticky and harder to manage but creates a lighter, more open structure in the final loaf.

Mastering hydration levels allows you to tailor your dough to specific bread textures and styles.

Does Hydration Only Apply to Sourdough?

No. Hydration applies to all bread types, not just sourdough. However, sourdough bakers talk about hydration more frequently because:

  • Sourdough ferments for longer, making hydration levels even more crucial for gluten development.
  • High-hydration sourdough produces lighter, airier loaves with complex flavors.

But whether you’re baking with commercial yeast or a sourdough starter, understanding hydration helps you fine-tune your dough for better results.

How to Adjust Hydration for Better Baking

If you want to modify your dough’s hydration, follow these simple guidelines:

  • Want a firmer dough? Reduce the water slightly for easier handling and shaping.
  • Want a softer, airier bread? Increase hydration to develop an open crumb.
  • Dough too sticky? Let it rest for 10–15 minutes to absorb moisture before adding more flour.
  • Dough too dry? Add a tablespoon of water at a time, mixing well before adjusting further.

Final Thoughts: Why You Should Understand Dough Hydration

Understanding dough hydration allows you to:

  • Control the consistency of your dough for easier handling.
  • Troubleshoot common baking issues, like dense loaves or sticky dough.
  • Improve your bread-making skills by adjusting hydration to suit your recipe.

Next time you’re baking, take a closer look at your dough’s hydration level—it might be the key to achieving the perfect loaf.
