How to Understand Sourdough Hydration for Beginners
Sourdough hydration is a significant factor that determines successful bread baking. The bread’s texture, crumb structure, and final flavor depend on this fundamental concept. Many beginners find it challenging to understand hydration levels during their bread-making trip.
Successful baking requires bakers to learn everything in hydration. This piece explains how to calculate hydration percentages and explores ranges from 60% to 75% and above. Bakers will discover how different hydration levels shape their bread’s characteristics. The content provides practical techniques to handle both low and high hydration doughs and shares useful tips to adjust moisture based on flour types.
What is Sourdough Hydration?
The first step to master sourdough lies in learning about hydration. Sourdough hydration shows the water-to-flour ratio in a recipe as a percentage. Bakers calculate this percentage by dividing the water weight by flour weight and multiplying the result by 100.
Definition of hydration percentage
Sourdough’s hydration percentage represents the relationship between water and flour weights, not just water content in the dough. To cite an instance, a recipe with 500g of flour and 350g of water yields 70% hydration. Bakers use this mathematical relationship to scale recipes while achieving consistent results.
How hydration affects bread texture and flavor
Water content substantially influences everything in sourdough bread:
- Fermentation Rate: Higher hydration speeds up fermentation
- Crumb Structure: Additional water creates larger holes and opens up the crumb
- Crust Development: Water levels shape the crust’s thickness and texture
- Dough Handling: Less water makes the dough firmer and easier to work with
- Keeping Quality: More water helps the bread stay moist longer
Common hydration ranges for sourdough
Sourdough bakers use different hydration levels that serve specific purposes:
| Hydration Range | Characteristics | Best For |
|---|---|---|
| 60-65% | Firm, easier to handle | Beginners, shaped loaves |
| 65-75% | Balanced texture | All-purpose baking |
| 75-90% | Wet, open crumb | Advanced bakers |
Bakers choose their preferred hydration level based on multiple factors. Experience level, flour type, and the desired end result play crucial roles in this decision. Whole grain flours need more water than white flour because of their higher absorption rate. The perfect hydration level for any recipe can shift based on local climate conditions. Humidity and altitude make a significant difference.
How to Calculate Sourdough Hydration
Sourdough hydration calculations need you to think over all water and flour sources in a recipe. Some bakers look at just the main dough ingredients, but proper hydration math must account for the starter’s flour and water too.
Simple hydration formula
A baker’s math principles guide the calculation of hydration percentage. The process requires these steps:
- Calculate the sum of all water weights (including starter water)
- Calculate the sum of all flour weights (including starter flour)
- Divide the total water amount by total flour
- Multiply your result by 100
Including starter in calculations
Sourdough bakers need to consider their starter’s hydration level at the time of mixing. A 100% hydration starter has equal amounts of flour and water. The math becomes clear with a simple example: 200g of starter at 100% hydration adds these ingredients to your recipe:
- 100g flour to total flour weight
- 100g water to total water weight
Bakers can calculate ingredients for starters with different hydration levels using this formula:
Amount of starter = flour + (hydration × flour)
Examples of hydration calculations
Let’s look at a recipe with:
- 500g all-purpose flour
- 350g water
- 200g starter (100% hydration)
Total flour calculation:
- Main recipe flour: 500g
- Starter flour: 100g
- Total flour = 600g
Total water calculation:
- Main recipe water: 350g
- Starter water: 100g
- Total water = 450g
Final hydration calculation:
450g ÷ 600g × 100 = 75% hydration
Starters with different hydration levels, like 80%, need separate flour and water calculations. The starter’s composition changes at different hydration levels. An 80% hydration starter has more flour than water – each 100g contains 56g flour and 44g water.
Effects of Different Hydration Levels
Different hydration levels in sourdough baking create distinct characteristics that change how you handle the dough and shape your bread’s final structure. Each hydration range is a chance to explore different baking techniques and overcome specific challenges.
Low hydration (60-65%)
Low hydration doughs yield breads with a tighter, more uniform crumb structure. These doughs are substantially firmer and easier to handle. Beginners find this dough type particularly suitable. The dough’s reduced water content creates a thicker, chewier crust and needs more time to ferment. Bakers prefer this hydration range when making sandwich loaves that need a consistent structure with fewer holes.
Medium hydration (65-75%)
Many bakers consider medium hydration their sweet spot because it strikes the perfect balance between easy handling and bread quality. The dough at this level shows stronger fermentation activity but remains easy to shape. Bakers can expect these characteristics in their final bread:
| Characteristic | Description |
|---|---|
| Crumb Structure | Moderately open with balanced hole distribution |
| Crust Quality | Medium thickness with good crispness |
| Handling | Manageable with standard techniques |
| Fermentation | Steady, predictable progression |
High hydration (75%+)
High hydration doughs offer unique opportunities and challenges. These doughs create the coveted open crumb structure that artisan bakers love. Extra water in the dough leads to:
- Better extensibility during fermentation
- More pronounced flavor development
- Thinner, crispier crusts
- Longer shelf life
Working with high hydration needs advanced skills. The dough gets sticky and just needs careful handling techniques. Fermentation happens faster than in lower-hydration doughs, so bakers must monitor it carefully. Professional bakers prefer coil folds over traditional stretch-and-folds to handle these wet doughs better.
Your flour choice substantially changes how different hydration levels behave. Whole grain flour’s water absorption rate exceeds all-purpose flour’s needs. A 75% hydration dough with all-purpose flour feels much softer than one made with whole wheat flour.
Tips for Working with Different Hydration Levels
Bakers need to understand how to work with doughs at different hydration levels to become skilled at making sourdough. The success of your baking goes beyond just the hydration percentage. You must adapt your techniques based on your flour choice and the temperature and humidity around you.
Handling low hydration dough
Low hydration dough (60-65%) demands specific techniques to achieve optimal results. Traditional kneading methods work effectively to develop the dough’s gluten structure. Temperature management plays a significant role since these doughs need more time to ferment. The baker’s schedule should factor in extra time to ensure proper development.
The best approach to working with low hydration doughs includes:
- The dough temperature should stay between 75-80°F
- Shaping requires firm, confident movements
- Fermentation takes longer than wetter doughs
- Signs of under-fermentation need careful monitoring
Techniques for high hydration dough
High hydration doughs (75%+) just need different handling approaches. Bakers should use specialized folding techniques instead of traditional kneading.
| Fold Type | When to Use | Purpose |
|---|---|---|
| Bowl Fold | Early fermentation | Original structure development |
| Coil Fold | Mid fermentation | Builds dough strength |
| Lamination | Later stages | Increases elasticity |
Cold fermentation works great with high hydration doughs, especially when you have to score them. Chilling shaped loaves overnight creates a firmer surface that’s easier to score and helps control fermentation timing. Bakers can work around their schedule rather than following the dough’s timeline with this technique.
Adjusting hydration based on flour type
Each flour type absorbs water differently, so bakers must adjust hydration levels accordingly. Strong bread flour handles higher hydration levels well – up to 80% compared to all-purpose flour. Whole grain flours need more water than white flours. The difference usually ranges between 5-10% extra hydration.
Weather conditions affect dough behavior substantially. Doughs feel softer in warmer temperatures above 80°F and might need less water. Cold weather often calls for extra hydration to maintain the right dough consistency. Bakers should begin with less water and add more gradually. The process depends on several factors:
- Flour protein content
- Ambient temperature
- Relative humidity
- Personal skill level
Success comes from finding the perfect balance for your specific conditions rather than following recipe hydration levels blindly. Bakers develop an accessible understanding of their local environment’s effects on dough through regular practice and careful observation.
Conclusion

FAQs
How can I determine the hydration level of my sourdough starter?
To find out the hydration percentage of your sourdough starter, use the formula: (Water (g) / Flour (g)) x 100. Remember to include the flour and water from your leaven as well. For instance, if your starter is made with equal parts flour and water, a 100g leaven would consist of 50g flour and 50g water.
What is meant by a 100% hydration sourdough starter?
A 100% hydration sourdough starter is maintained by feeding it equal weights of water and flour, such as 5 ounces of water to 5 ounces of flour. Conversely, a 166% hydration starter is fed with equal volumes, typically one cup of water (8.3 oz) and one cup of flour (5 oz).
What does a 75% hydration sourdough starter entail?
A 75% hydration in a sourdough starter indicates that the water content is 75% of the flour’s weight. For example, if you’re feeding your starter with equal amounts of flour and water, you’re maintaining it at 100% hydration. The final dough hydration can vary based on personal preference and there isn’t a universally ideal percentage.
What does an 80% hydration level signify in bread recipes?
An 80% hydration means that the water is 80% of the flour’s weight in the recipe. This ratio affects the texture and handling of the dough.
How should I choose the right hydration level for my sourdough bread?
Selecting the hydration level for your sourdough depends on several factors including the desired texture of the bread, your local climate, and the specific flour used. Generally, lower hydration results in denser bread, while higher hydration leads to lighter, airier loaves. It often requires experimentation to find the best hydration for your specific conditions and preferences.
