If you are ready to take your sourdough baking skills to the next level, this high hydration sourdough bread recipe is for you. With 84% hydration, this bread has a beautiful open crumb and the most perfect thin, crisp crust. You’ll be amazed what a little extra moisture can do for your sourdough loaf!

If you’ve ever made any of my sourdough recipes or watched my videos, you’ve probably noticed I like to keep things simple. I believe that with a little practice, anyone can make delicious sourdough bread. After all, I was by no means an expert baker when I first got started. 

Now that I’ve been baking sourdough bread weekly for a decade, I’ve gained a lot of confidence through experience. I can tell if my dough is right just by feel or when I should adjust proofing time for the seasons.

I enjoy challenging myself and creating sourdough versions of pretty much any recipe. Most importantly, I’m not afraid of a failed loaf, and you shouldn’t be either! 

This recipe truly fits the bill of a challenge. Making a higher hydration dough is not for the faint of heart. A wetter dough is tougher to work with and can be more temperamental. 

So if this is your first time making sourdough, you may want to start with my Beginner’s Sourdough Bread Recipe here, which is at 74% hydration. 

But you also don’t have to be a seasoned sourdough connoisseur to try this recipe. This loaf is for anyone desiring a more airy crumb, full of those signature sourdough holes.  

All you need to master this recipe is an understanding of hydration and a little practice. If the first loaf or two doesn’t turn out just right, that’s okay! You can always turn it into sourdough croutons, bread pudding, French toast casserole, or breadcrumbs

What is high hydration sourdough?

Sourdough hydration refers to the water-flour ratio of a recipe and is represented by a percentage. In other words, it is all about how much moisture is in your dough. 

Anything above 80% is considered high hydration. This recipe is 82%. My other recipes, such as my no-knead bread, typically fall into the 70% range. 

This may sound complicated and intimidating, but it is actually very easy to calculate. 

Simply take the grams of water and divide by the grams of flour in a recipe. Multiply that number by 100 and you get your hydration percentage. 

Now, don’t forget, a sourdough starter is made up of flour and water also, so it must be included in your calculation for an accurate result. 

So, how do you know how many grams of starter to associate with flour and how many to water?

100% Hydration Sourdough Starter

I use a 100% hydration sourdough starter. All that means is that I feed it equal parts flour and water. Sometimes you’ll see people refer to this as a 1:1:1 sourdough starter, meaning 1 part starter, 1 part flour, and 1 part water.

However, the sourdough starter does not have to be equal to the amount of water and flour added. So, a 1:2:2 sourdough starter would also be 100% hydration because it is still fed equal parts water and flour.

How to Calculate Hydration

Remember when you asked yourself when you would ever need to use math in real life?

Well, the time has come! 

Yes, baking can sometimes require quite a bit of math. Of course, as a homeschool mom, I love this. There is always a lesson to be learned, even when baking bread.

To start, divide the grams of sourdough starter called for in half and give half to the total flour count and half to the total water count. This is of course assuming the starter is at 100% hydration. 

For example, this recipe calls for 390 grams of water and 475 grams of flour. With 100 total grams of starter, add 50 to the flour and 50 to the water.

This gives you a total of 440 grams water and 525 flour. 

440 divided by 525 multiplied by 100 is equal to 84%.

It’s that easy!

The Benefits of High Hydration

So, what is the benefit of all this math?

The main reason bakers choose high-hydration doughs is to generate a more open crumb. So, if you prefer a sourdough bread that is airy with all of those classic sourdough holes, trying a recipe with higher water content may be right for you. 

In addition to an airy crumb, you also may end up with a thinner crust. 

Higher hydration doesn’t necessarily mean better, though. It’s really a personal preference as to what hydration level is best for you. No matter the hydration level, it’s still sourdough. So, that means it will be delicious at 65%, 85%, or anything in between. 

Tips When Baking a High Hydration Recipe

  • Watch your dough closely during bulk fermentation. Higher hydration doughs tend to ferment faster. Over fermented dough will become sticky and unworkable. The amount of time it takes for your dough to proof depends on many factors, including the maturity of your starter and environment. 
  • Be gentle when dealing with high hydration dough after the bulk ferment and during shaping to make the crumb more open and even. Using a bench scraper can help move your dough more gently. 
  • You need an active starter for this recipe that is at 100% hydration, meaning it is fed equal parts water and flour. New to sourdough? Learn how to make your own sourdough starter here.

Ingredients

Unbleached all purpose flour

Whole wheat flour

Bread flour โ€“ Typically, I would say you can easily replace the bread flour with more all purpose. In this recipe, though, the higher protein content of the bread flour helps balance the extra water. 

100% hydration active sourdough starter โ€“ This means your starter should be fed equal parts flour and water before making this recipe. 

Water โ€“ Filtered water is ideal

Salt

Tools You May Need

Large Mixing Bowl

Cast Iron Dutch Oven – Don’t have a Dutch oven? Learn how to bake bread without one here.

Banneton Basket – You can also use a basket or bowl with a tea towel. Make sure to flour the towel well so the dough does not stick. 

Dough Whisk – Not a requirement, but I love mine.

Kitchen Scale – Weight measurements are key in this recipe to get good results.

How to Make High Hydration Sourdough Bread

Feed a sourdough starter 4-12 hours before making your bread. The time it takes a starter to double in size and become active and bubbly depends on factors such as temperature and the maturity of your starter.

Combine the flour and warm water in a mixing bowl. I find using a dough whisk works best for this. 

Allow this mixture to rest for 30 minutes. This is called autolyse, the process of hydrating the flour. 

After the autolyse, add in the sourdough starter by dimpling it in with wet hands. 

Sprinkle the top of the dough with salt. 

Use your hands to mix the dough until it comes together. This takes about 5 minutes. Cover the dough with plastic wrap or a damp tea towel and allow another 30 minute rest. 

Stretch And Fold

This is a no knead recipe. So, for gluten development, perform 6 rounds of stretch and folds. 

With the dough in a large bowl, grab the edge of the dough and firmly pull up, stretching it upwards. Place the dough into the center of the dough ball. Give the bowl a quarter turn and do this same process again. Repeat this one to two times. This is considered one round of stretch and folds. Repeat according to the directions below. 

First 3 stretch and folds โ€“ every 15 minutes.
Last 3 stretch and folds โ€“ every 30 minutes.

If your dough is sticking to your hands, dip your fingers in a little water before each stretch and fold. 

Bulk Ferment

To ensure a beautiful rise and airy crumb, the dough will need to bulk ferment until doubled. To do this, cover the dough with a wet towel or plastic wrap to avoid a crust forming. 

With a high hydration dough, this process may not take as long to ferment as other doughs. Keep an eye on it! The time will vary for everyone depending on temperature and maturity of the starter used. 

When your dough is done fermenting, it should have doubled in size and have bubbles all over the surface.

Over fermented dough will become a wet, sticky mess. 

Shaping

Add a little bit of flour to a work surface. 

Gently take your dough out of the bowl. Be extra careful with this type of dough! 

Shape it into a ball by creating surface tension. To do this, gently spin it towards you. 

Let it sit out 15-20 minutes uncovered. This time around, you want the dough to form a crust so it won’t stick to the banneton basket or tea towel during the overnight rise.

Cover with plastic and proof 12-15 hours in the refrigerator.

Scoring

Before removing your bread from the fridge, preheat your oven to 500 degrees F. Place the Dutch oven inside and preheat for 1 hour.ย

Right before this hour is up, remove your dough from the fridge. Dust the top with flour and score using a razor blade or scoring lame. If you are hoping to do some fun designs, check out my tips on scoring here. 

Bake

Sprinkle the bottom of the Dutch oven with flour or use a piece of parchment paper. Transfer the dough to the Dutch oven. 

Bake for 20 minutes at 500 F degrees with the lid on.

Take the lid off, turn the oven temperature down to 475 F, and bake an additional 25 minutes or until browned. To ensure your bread is done, use a kitchen thermometer to test the temperature. Sourdough should be around 205 F degrees. 

Carefully take your finished loaf out of the oven. After cooling for a few minutes, take your bread out of the Dutch oven and place on a wire rack to finish cooling. 

Allow your bread to cool completely before slicing into it, no matter how tempting it may be. If you want to get the perfect slice, find all my tips, tricks, and favorite tools here

FAQ

What does high hydration do to sourdough?

Higher hydration sourdough bread is going to have a more open crumb. This is the main benefit of a higher water content. You may also notice your dough ferments faster. 

Does higher hydration make more open crumb?

Yes! An open crumb is when you have more holes in your bread. So, if you tend to have trouble with your loaves being a bit too dense, a higher hydration dough may help. 

Should sourdough starter be 100% hydration?

I always use 100% hydration for my sourdough starter, which is the most common hydration level. There are also liquid starters that use more water and stiff starters that use less. 

What is the average sourdough hydration?

You can find sourdough recipes ranging from 60% to 90%. Most of my loaves are in the 70 to 75% range. Anything above 80% is considered high. While anything below 70% is a lower hydration dough. 

How to Store a Finished Loaf

One of the benefits of making a higher hydration loaf is storage. Thanks to that extra moisture, it won’t dry out as fast, helping it to last longer! 

Store your bread in a cool, dry place in a bread bag or bread box for 5 to 7 days. If you don’t have a bread bag or box, there are other ways you can store your sourdough bread for ultimate freshness. Check out my best storage tips here!

      Amazing! I have been using your 70% hydration loaf and it is amazingly simple and always turns out wonderfully. (*Thanks for the hydration information you linked here: https://www.farmhouseonboone.com/sourdough-hydration-how-to-make-delicious-bread/#:~:text=Step%201%3A%20Calculate%20the%20amount,100%20grams%20to%20my%20water.

      I tried the high hydration bread and it turned out EXACTLY as you described it! The proofing picture was a welcome addition, as I am used to the proof looking differently for the lower hydrations. Bread tastes amazing and has the larger holes one hopes for with a small soft crumb! Will bring this to the Holiday Open house and use for pull apart brie. ๐Ÿ™‚

      What is the purpose of mixing AP flour with bread flour? Why not use just bread flour with the higher protein / gluten content? Can you explain what the addition of AP flour does to the crust and crumb of the loaf? Thanks!
