The beauty of this method is its adaptability. Use it for sandwiches, toast, or even French toast—each slice will be packed with flavor. Whether you're a beginner or an experienced baker, this 65% hydration sourdough recipe will become your go-to for homemade bread that's worth the wait.
Ingredients for 65 hydration sourdough bread
Six simple ingredients transform into a loaf with crispy crust and airy crumb.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| All-Purpose Flour 🌾 | 3 ½ cups | Bread flour preferred for better structure |
| Whole Wheat Flour 🌾 | ½ cup | For added flavor and nutrition |
| Water 💧 | 1 ½ cups | Room temperature, filtered preferred |
| Salt 🧂 | 1 ½ tsp | Fine sea salt or kosher salt |
| Olive Oil 🫒 | 1 tbsp | For dusting and scoring |
| Cornmeal 🌽 | ¼ cup | For dusting parchment paper |
| Rice Flour 🌾 | 2 tbsp | For dusting inside Dutch oven |
| Ice Water ❄️ | ½ cup | For final shaping and chilling |
The sourdough starter is your flavor foundation—it should be bubbly and active when you use it. If yours is sluggish, feed it 12-24 hours ahead. For flour, King Arthur bread flour gives the best structure, but all-purpose works in a pinch. I always grab mine from Whole Foods or King Arthur's website—their packaging keeps it fresh. The whole wheat flour adds depth, but if you're short on time, skip it entirely. Salt matters here: Maldon flaky sea salt dissolves beautifully, but regular kosher salt works too. Just measure carefully—too much can inhibit fermentation.
No bread flour? Add 1 tbsp vital wheat gluten per cup of all-purpose flour for better gluten development. Running low on rice flour for the Dutch oven? Semolina works just as well. The ice water might sound odd, but it's key for a tight, smooth final shape—just pour it into your mixing bowl before handling the dough. For scoring, a lamé or razor blade makes clean cuts, but a sharp knife works too. If your starter isn't ready, you can use 1 tbsp active dry yeast instead, but the flavor won't be quite the same. And trust me, the olive oil makes all the difference—California avocado oil has a neutral taste that won't overpower.
This dough is best baked fresh, but you can shape it and refrigerate it overnight for 12-24 hours—the slow fermentation adds even more flavor. Once baked, the loaf stays fresh for 3-4 days at room temperature, wrapped in a clean kitchen towel. For longer storage, freeze slices for up to 3 months. I always make an extra batch—it's perfect for French toast or garlic bread later in the week. The key to reheating? Wrap cooled slices in foil and warm in a 350°F oven for 5-7 minutes—crispy crust, every time.

Step-by-step instructions for 65 percent hydration sourdough bread
Here's how to make a loaf with a crispy crust and perfect fermented tang—no shortcuts, just reliable technique.
Mix Dough Using the Autolyse Method
In a large mixing bowl, combine the 3.5 cups all-purpose flour, 0.5 cup whole wheat flour, and the 1.5 cups water at room temperature. Mix with your hands or a dough whisk until just combined—no dry bits should remain. This initial mix is called an autolyse, and it helps develop gluten while allowing the flour to fully hydrate.
Cover the bowl with a damp towel and let it rest for 30 minutes. You'll notice the dough becomes smoother and more pliable during this time. This step is crucial for creating a lighter, more open crumb structure in your bread. Don't skip it—patience here pays off in texture.
Add Starter, Salt, and Olive Oil
After the autolyse, add the 0.5 cup active sourdough starter and the 1.5 tsp salt to the bowl. Mix well to distribute evenly. Then, drizzle in the 1 tbsp olive oil and incorporate it by hand, pressing it into the dough. The oil helps create a tender crumb and contributes to that signature crispy crust we're aiming for.
At this point, the dough will feel sticky but manageable. If it's too wet, you can add 1 tablespoon of flour at a time until it comes together without sticking to your fingers. Now, perform a series of stretch and folds every 30 minutes for 2 hours. This builds strength and elasticity in the gluten structure, which is essential for that perfect oven spring later.
Bulk Ferment Until Ready for Shaping
After the final set of stretch and folds, let the dough rest, covered, for 30 minutes to relax. Then, shape it into a loose round by gathering the edges toward the center and tucking them under. Place the dough seam-side up in a lightly oiled bowl, cover it, and let it bulk ferment at room temperature for 4-6 hours, or until it has nearly doubled in size and looks puffy with bubbles on the surface.
Here's where the magic happens: the dough should feel jiggly when gently tapped, and it should spring back slowly when poked with a finger. If your kitchen is cool, this might take longer—don't rush it. A proper bulk fermentation develops maximum flavor and ensures that crispy crust we're after. I like to check it every hour during the last few hours to monitor progress.
Pre-Shape, Bench Rest, and Final Shape
Turn the dough out onto a lightly floured surface and gently pre-shape it into a round by pushing the edges toward the center. Let it rest for 20-30 minutes—this bench rest relaxes the gluten so it holds its shape better during final shaping. While it rests, dust a piece of parchment paper with 2 tbsp rice flour and place it on your baking sheet.
After the rest, shape the dough into a tight boule by pulling the edges up and under, creating surface tension. Place it seam-side down on the prepared parchment. Cover loosely and let it proof at room temperature for 1-2 hours, or until it has visibly risen by about 50% and feels light when tapped. The dough should feel springy but not overly tight—this is the perfect moment for baking.
Score, Bake, and Achieve That Crispy Crust
Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. Meanwhile, score the dough with a sharp razor blade or lame by making a deep cut down the center. This controls expansion and creates that beautiful ear you see on artisanal loaves. Dust the outside of the Dutch oven with 0.25 cup cornmeal for easy removal.
Carefully transfer the scored dough to the hot Dutch oven, cover it, and bake for 20 minutes. Then, remove the lid and bake for another 20-25 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should reach 190-200°F when checked with an instant-read thermometer.
Let the bread cool on a wire rack for at least 1 hour before slicing—this allows the steam to escape and the crumb to set properly. You'll be rewarded with a loaf that has a crispy, crackly crust and a tangy, open crumb perfect for sandwiches or toast. The ice water we held back? We'll use it next time for a quick refresh of our starter!
Pro Tips For Making 65 Hydration Sourdough Bread
- Scale Your Starter: Weigh your active starter before mixing—it’s the most common math error. A 65% hydration dough demands precision, and guessing leads to either a gummy loaf or wasted flour. I learned this the hard way when my first batch turned out like a brick because I eyeballed the starter.
- Mix Whole Wheat Last: Add the whole wheat flour after the autolyse, then mix it in gently. It’s denser and absorbs water slower, so forcing it in early can create a lumpy dough that’s harder to stretch and fold. Trust me, your kneading will thank you.
- Bulk Ferment at 72°F: If your kitchen runs hotter or colder, adjust accordingly—72°F is the Goldilocks zone for this dough. Too cold? It’ll take forever. Too hot? The whole wheat will sour too fast. I use a proofing box set to 72°F and time my bulk ferment to 4–5 hours for consistent results.
- Score Deep and Slow: Use a razor blade (not a lame serrated knife) and cut just deep enough to release steam without tearing the crust. Drag it across the dough at a 45-degree angle—too shallow, and your loaf won’t expand properly; too deep, and you’ll lose structure. Practice on a scrap dough first if you’re nervous.
Dietary considerations for this dish
Gluten-Free Adaptations
If you need a gluten-free version, replace the all-purpose and whole wheat flours with a 1:1 gluten-free flour blend like King Arthur Measure for Measure. Add 1 tbsp xanthan gum per cup of flour blend to mimic gluten's structure.
The hydration ratio stays the same, but your dough will be stickier—work quickly and use extra rice flour for dusting. Expect a denser crumb, but the tangy flavor from the sourdough starter remains intact. 🌾
Low-FODMAP Options
For low-FODMAP diets, swap the whole wheat flour for certified gluten-free oat flour (check for cross-contamination). Use 1 cup water instead of your starter—mix 1 tbsp active dry yeast with 1 tbsp honey to replace the fermentation.
Reduce the bulk fermentation time to 3-4 hours since yeast ferments faster. The result is still flavorful but gentler on digestion. Always verify all ingredients are certified low-FODMAP.
Keto-Friendly Modifications
This recipe isn't naturally keto, but you can create a low-carb version by replacing flours with almond flour and coconut flour (use 2:1 ratio almond to coconut). Add 1 extra egg and 1 tbsp psyllium husk powder to bind the dough.
Reduce water to 1 cup and increase starter to 0.75 cup for fermentation. Bake at 375°F for 30-35 minutes—the result is a dense, nutty loaf perfect for keto diets. 🥜
Allergen-Free Considerations
For nut-free kitchens, use sunflower seed flour instead of almond flour in keto versions. Ensure your starter contains no dairy (many contain milk powder). Check salt for iodine additives if avoiding all allergens.
For egg-free modifications, add 1 tbsp ground flaxseed mixed with 3 tbsp water as a binder. Always verify all ingredients for hidden allergens—cross-contamination is a real risk in shared kitchens.
Dairy-Free Substitutions
This recipe is already dairy-free, but if your starter contains milk powder, make your own with just flour and water. For extra richness, add 1 tbsp melted coconut oil instead of olive oil.
The flavor remains tangy and robust—dairy isn't needed for authentic sourdough character. If you notice the crust is too pale, brush with coconut milk before baking for color and moisture. 🥥
Nutrition facts
Frequently asked questions about 65% hydration sourdough bread
Why does hydration matter in sourdough?
The 65% hydration means the dough contains 65% water by weight relative to flour, creating a balance between manageability and flavor. Lower hydration (60%) yields a firmer dough with a thicker crust, while higher hydration (75%) produces a more open crumb but can be trickier to shape. This ratio delivers that perfect mix of crispy crust and tender interior without being overly sticky.
Can I skip the autolyse step?
While possible, skipping the 30-minute autolyse weakens gluten development, leading to a denser crumb and less oven spring. This rest period hydrates the flour fully and relaxes the proteins, making stretch-and-folds more effective. For beginners, it’s worth the wait—it’s the secret to that light, airy texture we all crave.
How do I know when bulk fermentation is done?
Your dough is ready when it’s 50-75% larger, jiggly when tapped, and springs back slowly when poked. Look for bubbles on the surface and a slightly domed shape. In cooler climates (65°F or below), this may take 6-8 hours—patience ensures maximum flavor and rise. A dough that’s too firm or hasn’t risen enough will yield a dense loaf.
What if my dough is too sticky to handle?
If the dough feels unmanageable, dust your work surface with rice flour (not all-purpose) and wet your hands slightly to prevent sticking. For extra grip, use a dough scraper** to lift and fold. If it’s extremely wet, add 1 tbsp flour at a time until it’s just workable—but avoid over-drying, which can inhibit fermentation. The goal is a dough that’s sticky but not gluey.
How can I get a darker crust without burning?
For a deeper color, bake uncovered for the last 10-15 minutes at 425°F after removing the lid. Brush the crust with water or coconut milk before baking for a glossy finish. Avoid opening the oven door early—temperature drops cause uneven browning. A preheated Dutch oven with steam is key for that artisanal look.
