Sourdough Bread Hydration Explained: Achieve Perfect Dough Every Time
A 5% change in water content can revolutionize your sourdough bread. The proper hydration levels determine whether your loaf turns out dense and chewy or light and airy.
Our extensive testing of different sourdough bread hydration levels taught us something important. Becoming skilled at hydration requires more than following a recipe— it requires a deep understanding of water and flour interaction to create a perfect crumb structure.
The hydration ratio is often crucial when you face sticky dough or dense loaves. Each hydration percentage, from a beginner-friendly 65% to advanced levels above 80%, produces unique results in the final bread.
Let’s examine the science behind perfect sourdough. You’ll learn everything about controlling moisture levels in your dough to achieve amazing results consistently.
Understanding Sourdough Hydration Basics
Let’s break down the meaning of sourdough hydration. Hydration simply shows the relationship between water and flour in your dough as a percentage. Bakers use this measurement to predict the outcome of their bread.
What Hydration Really Means for Your Bread
The concept of hydration in sourdough bread refers to the total water compared to flour. This mathematical relationship helps bakers understand dough behavior. For example, 70% hydration means using 70 grams of water for every 100 grams of flour.
The Science Behind Water-to-Flour Ratios
Here’s how we calculate hydration:
- Add up all water sources (including liquid in the starter)
- Add up all flour sources (including flour in the starter)
- Divide total water by total flour
- Multiply by 100 to get the percentage
How Hydration Affects Bread Texture
Your dough’s water content affects your final loaf’s characteristics by a lot:
- Lower hydration (60-65%): Creates denser crumb, easier handling, and better toasting properties
- Medium hydration (70-75%): Offers balanced texture with moderate holes
- Higher hydration (80%+): Produces open crumb, thin crispy crust, and better fermentation
Water makes fermentation possible and hydrates proteins and starches. It substantially affects the bread’s texture and flavor development. Higher hydration creates better extensibility and moisture retention. Lower hydration gives more control during shaping and results in a chewier final texture.
Mastering Hydration Through Touch and Sight
Reading your dough’s signals is vital to get consistent results in sourdough baking. You need visual and tactile awareness of your dough’s state to get the hydration right.
Visual Clues for Perfect Dough Consistency
A properly hydrated dough shows these signs:
- The surface looks smooth with slight stretching
- You can see small bubbles throughout
- The dough appears soft and pillowy
- The top has a slight tautness
- The surface shows even dimpling
Tactile Tests for Different Hydration Levels
Two reliable tests help check hydration levels. Here’s how we do it:
- The Poke Test:
- Press your finger gently into the dough
- Good hydration means the dough bounces back slowly in about 10 seconds
- Under-hydrated dough springs back quickly
- The over-hydrated dough doesn’t spring back
The windowpane test gives you another way to check: Take a small piece and stretch it gently. The dough should stretch thin enough to see light through without breaking.
Common Texture Problems and Solutions
Environmental factors cause most texture issues. In humid conditions, the dough needs 50g less water per 400g flour; environments might need extra water.
Sticky dough often means the flour type needs adjusting. Bread flour and whole wheat varieties need more water than all-purpose flour. The dough’s texture improves a lot after resting for 15 minutes before handling.
Temperature makes a big difference. The dough works best between 75°F to 78°F (23°C to 25°C) for good fermentation and water absorption.
Choosing the Right Hydration Level
Your experience matters more than ambition when selecting an ideal sourdough hydration level. We found that matching hydration to your skill level consistently guides you to better results.
Beginner-Friendly Low Hydration (60-65%)
New bakers should start with 60-65% hydration. Your dough at this level will be:
- Easier to handle and shape
- Less sticky during folding
- More forgiving during proofing
- Perfect for sandwich-style bread
- Ideal to develop simple techniques
Intermediate Medium Hydration (70-75%)
After you become skilled at lower hydration, try moving to 70-75% hydration. This sweet spot combines manageable handling with improved texture. This range produces excellent everyday sourdough with balanced characteristics. The dough becomes more extensible and creates that classic artisan-style crumb structure we all love.
Advanced Hydration (80%+)
We found that 80% or higher hydration requires solid experience and confident handling techniques. These wet doughs just need gentle coil folds rather than traditional kneading. The results make the challenge worthwhile—you can expect a dramatically open crumb structure and thin, crispy crusts.
Note that flour type greatly affects hydration needs. Whole grain flours are “thirstier” and can handle higher hydration levels, while all-purpose flour typically needs less water for optimal results. Start conservatively with hydration and increase gradually as your confidence grows.
Troubleshooting Hydration Issues
Making sourdough can feel like solving a puzzle, especially when dealing with hydration problems. We’ve been in many sticky situations and found some reliable fixes for common issues.
Fixing Overly Wet or Dry Dough
These signs tell us there’s a hydration problem:
- Your dough spreads like a pancake – cut back water by 50g per 400g of lour
- Your hands get super sticky – add flour bit by bit during folds
- The dough feels dry and tough – add water 25g at a time
- You get dense, heavy bread – check your bulk fermentation time
The “hold-out water” method works great for wet dough. Start with 75% of the recipe’s water, then add the rest only if needed.
Adjusting for Different Flour Types
Each flour type affects water absorption significantly. Here’s what works best:
- Strong bread flour (14%+ protein) handles more water well
- All-purpose flour needs 5-10% less water
- Whole grain flours need 10-15% more water
- Rye flour needs close watching because it soaks up water slowly
Environmental Factors Affecting Hydration
In humid weather, you should cut water by 3-4% to balance the moisture in the air. Cold water or even ice works great in summer for both starter and dough to keep fermentation just right.
Dry conditions require a bit more water and careful temperature monitoring. Room temperature between 75-80°F (23-26°C) gives reliable results regardless of humidity level.
Tough environments might need 2.5-3% salt to control fermentation and strengthen the dough. This small change helps a lot with tricky hydration issues.
Conclusion
Becoming skilled at sourdough hydration turns challenging dough into beautiful, consistent bread. Countless bakes have taught us that success comes from understanding simple techniques, reading dough signals, and matching hydration levels to your experience.
The right hydration needs practice and patience. Your journey should begin with lower hydration dough at 65%.

FAQs
What is the ideal hydration level for sourdough bread? The perfect hydration level for sourdough bread typically ranges between 70% and 90%. However, beginners may start with lower hydration levels, around 60-65%, for easier handling. As you gain experience, you can gradually increase the hydration to achieve more open crumb structures and better fermentation. Remember that optimal hydration can vary depending on the type of flour used and environmental factors.
How can I strengthen high-hydration sourdough dough? To strengthen high-hydration sourdough (around 85%), try these techniques:
- Use strong wheat flour with a high protein content
- Build a levain using 25% of your total flour a day in advance
- Add salt to help improve the structure
- Perform a short autolyze (no longer than an hour) with the remaining flour
- After kneading, do at least four stretch and fold sessions to develop gluten
Is 75% hydration sourdough difficult to work with? A 75% hydration dough can be slightly more challenging to handle compared to lower hydration doughs, especially for beginners. However, this hydration level offers a good balance between workability and desirable bread characteristics. It can result in a more open crumb structure and better keeping qualities. You can successfully manage 75% hydration dough with practice and proper techniques.
How do you create a 100% hydration sourdough starter? A 100% hydration sourdough starter is made by combining equal parts water and flour by weight. For example, you would use 100 grams of water for every 100 grams of flour. This 1:1 ratio makes it easy to maintain and use in recipes, as most are designed with this hydration level in mind. To create one, mix equal flour and water weights, then feed it regularly with the same ratio to maintain 100% hydration.
What’s the relationship between hydration and oven spring? Hydration plays a crucial role in achieving optimal oven springs. Higher hydration levels (70-80%) generally contribute to better ovenspringsg due to increased steam production during baking. This steam helps create a crispy crust and allows for maximum expansion. However, extremely high hydration can lead to dough that’s too weak to hold its shape. Finding the right balance for your flour type and baking conditions is key to achieving the best oven spring.
How does flour type affect hydration in sourdough? Different flour types have varying water absorption capacities, which significantly impact hydration:
- Strong bread flour (high protein content) can handle higher hydration levels
- All-purpose flour typically requires less water (reduce hydration by 5-10%)
- Whole grain flours are more absorbent and may need 10-15% more water
- Rye flour absorbs water slowly and requires careful maintenance. To achieve the desired dough consistency, constantly adjust your hydration based on the specifics you use.
