A 65% hydration sourdough bread recipe delivers the perfect balance of crispy crust and open, airy crumb—exactly what separates home-baked loaves from store-bought. The key lies in precise hydration, controlled fermentation, and baking with steam to develop that signature texture.
After years of experimentation, I’ve perfected a method that yields a loaf with a satisfying crackle and tender interior, every time.
This recipe emphasizes traditional techniques like bulk fermentation and cold proofing, but includes modern shortcuts like autolyse to simplify the process without sacrificing quality. You’ll work with a lively starter, a mix of bread flour and whole wheat for structure, and careful shaping to prevent tearing.
The result? A loaf with an open crumb, thin crust, and just the right amount of chew.
Baking with steam is critical for that crispy crust, and scoring the dough before baking ensures an even rise and prevents bursting. Once cooled properly, the bread develops its full flavor—nutty, tangy, and slightly sweet. Store it at room temperature for freshness or freeze slices for later.
Whether you’re a seasoned baker or new to sourdough, this recipe breaks down each step clearly, from mixing to baking, with troubleshooting tips for common issues like dense crumb or weak structure. Let’s get started on your next perfect loaf.
Ingredients for 65 hydration sourdough bread
Six essential ingredients and precise techniques create the perfect 65% hydration sourdough loaf.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | Fed and bubbly, 100% hydration |
| Bread Flour 🌾 | 3 ½ cups | High-protein for structure, 12-13% protein |
| Whole Wheat Flour 🌾 | ½ cup | Adds nutty depth and slight density |
| Granulated Sugar 🍚 | ¼ tsp | Feeds yeast for initial rise |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain for even distribution |
| Water 💧 | 2 ½ cups | Filtered or dechlorinated preferred |
| Olive Oil 🫒 | ¼ tsp | Extra-virgin for dough elasticity |
| Cornmeal 🌽 | ¼ cup | For dusting baking surface |
| Ice Water ❄️ | ½ cup | For final shaping and scoring |
The sourdough starter is the foundation—it must be active and bubbly, with a 100% hydration ratio for consistency. For the best results, use a starter that’s been fed 4-12 hours before mixing. King Arthur or Caputo bread flour provide the high gluten structure needed for that open crumb, while the whole wheat adds depth. Store your flours in airtight containers to prevent rancidity. If you’re using a different brand, check the protein percentage—12-13% is ideal for this hydration level. The water should be room temperature (around 75°F), as cold water slows fermentation while warm water can overproof the dough.
No bread flour? King Arthur all-purpose plus an extra 1 tbsp vital wheat gluten per cup gets you close. Whole wheat can be swapped for rye flour at half the amount for a darker loaf. The olive oil is optional but worth including—it improves dough elasticity and crust color. For scoring, a lamé or razor blade works best, but a sharp serrated knife in a pinch. If your starter isn’t ready, instant yeast at 0.25 tsp can be used as a backup (though flavor will differ). The cornmeal dusting prevents sticking during shaping, but semolina works too for a nuttier flavor. Always measure your water by weight for precision—1 gram of water equals 1 milliliter (though we’re using cups here).
Freshly mixed dough can be bulk fermented for 4-6 hours at room temperature or overnight in the fridge for deeper flavor. Shape the dough gently to avoid overworking—stretch and fold is the preferred method over aggressive kneading. For scoring, practice on scrap dough first to get the right tension. The loaf develops its full flavor when baked with steam, which creates that signature crispy crust. Cool completely on a wire rack—at least 2 hours—before slicing to prevent gumminess. Store wrapped at room temperature for 3 days or freeze slices for up to 3 months for freshness.
Why You’ll Love This Recipe

- Budget-Friendly Staple: A little starter goes a long way, and the rest of the ingredients won’t break the bank. I make this weekly, and it’s cheaper than buying even the “cheap” loaves at the store. Plus, the whole wheat adds fiber, so you’re basically feeding yourself and your wallet.
Step-by-step instructions for 65 percent hydration sourdough bread
Mastering this hydration level creates the perfect balance between structure and openness in your loaf.
Autolyse the Flour and Water Mixture
In a large mixing bowl, combine the 2.5 cups water and 3.5 cups bread flour using your hands or a dough whisk. The goal is to create a shaggy, sticky dough with no dry flour remaining. This initial hydration phase, called autolyse, allows the flour to fully absorb moisture and develop gluten strands before adding other ingredients.
Cover the bowl with plastic wrap or a damp towel and let rest for 30 minutes. During this time, you’ll notice the mixture transform from loose and crumbly to smoother and more cohesive. This step is crucial for developing gluten structure without overworking the dough later. The dough should feel slightly tacky but not wet when you press your finger into it.
Incorporate Starter, Salt, Sugar, and Olive Oil
After the autolyse, add the 0.5 cup active sourdough starter, 0.25 tsp granulated sugar, 1.5 tsp diamond crystal kosher salt, and 0.25 tsp olive oil to the bowl. Using a dough scraper or your hands, gently incorporate these ingredients into the dough until fully combined. The sugar feeds the starter, the salt enhances flavor and strengthens gluten, and the olive oil improves elasticity.
Begin developing the gluten by performing a series of stretch and folds every 30 minutes for 2 hours. To do this, wet your hands to prevent sticking, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat this process in four directions. After each set, the dough should feel slightly firmer and more elastic. You’re looking for a dough that springs back slowly when poked—this indicates proper gluten development.
Bulk Fermentation at Room Temperature
After the final stretch and fold, cover the dough again and let it undergo bulk fermentation at room temperature (70-75°F) for 4-6 hours. The dough should nearly double in size and develop visible bubbles throughout. To check for readiness, perform the “poke test”—press your finger gently into the dough. If it springs back slowly, it’s ready for shaping.
If your kitchen is cooler, extend the fermentation time up to 8 hours, but avoid exceeding this duration to prevent overproofing. The dough should feel soft, slightly sticky, and have a pleasant, tangy aroma from the active starter. This stage is where the flavor develops, so patience is key—rushing here will compromise both texture and taste.
Pre-Shape, Bench Rest, and Final Shape
Lightly dust a clean surface with 0.25 cup cornmeal to prevent sticking. Turn out the dough and gently pre-shape it into a loose round by folding the edges toward the center. Cover it loosely and let it rest for 20-30 minutes. This bench rest relaxes the gluten, making it easier to handle during final shaping.
After the rest, shape the dough into a tight boule or batard. For a boule, gather the dough into a ball with the seam side down. For a batard, roll it into a log shape. Both shapes should be smooth and taut, with no loose edges. Place the shaped dough on a lined baking sheet or in a proofing basket, seam side up, and cover again. Allow it to proof at room temperature for 1-2 hours or until it has risen by about 50%. The dough should feel light and airy when gently pressed.
Score and Bake for Crusty Perfection
Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. While the oven heats, prepare 0.5 cup ice water in a small bowl. Using a sharp razor or lame, score the dough in a decorative pattern—this controls expansion and creates an appealing crust. Immediately place the scored dough into the hot Dutch oven.
Bake covered for 20 minutes, then remove the lid and bake uncovered for an additional 20-25 minutes until the internal temperature reaches 205-210°F. The crust should be deep golden brown with a crisp texture, and the bread should sound hollow when tapped on the bottom. Let the bread cool on a wire rack for at least 1 hour before slicing to allow the crumb to set properly.
Pro Tips For Making 65 Hydration Sourdough Bread
- Weigh Your Flours: Skip the scooping—use a kitchen scale for bread flour and whole wheat flour. The recipe’s 65% hydration relies on precise ratios, and volume measurements can throw off the dough’s structure, especially with whole wheat’s denser crumb. I learned this after making a loaf that was either too sticky or too dry—turns out, my “eyeballing” was way off.
- Autolyse First: Mix the bread flour, whole wheat flour, and water (from your starter) before adding sugar or salt, then let it rest 30–60 minutes. This hydrates the flours fully, making the final kneading (or stretch-and-folds) easier and developing gluten more evenly. Sounds weird, but it works—your dough will be smoother and less likely to feel gummy later.
- Salt the Water: Dissolve the Diamond Crystal kosher salt directly in the water before mixing it with the starter. This ensures even distribution—no clumpy salt pockets that can slow fermentation or leave bitter spots. I was skeptical until I tried it; now I can’t go back.
- Proof Until Puffy: Don’t rush the final proof—look for a loaf that’s doubled in size and has a dome shape with visible creases when poked. Whole wheat slows fermentation, so it might take 1–2 hours longer than white-flour dough. Resist the urge to bake early, or you’ll end up with a dense, underproofed loaf. (Your future self will thank you.)
Pro cooking tips for this dish
Autolyse Mastery
The 30-minute autolyse is where gluten development begins—don’t skip it! Combine your 2.5 cups water and 3.5 cups bread flour first, then let the flour fully hydrate before adding other ingredients. This step relaxes the gluten proteins, making stretch-and-folds easier later.
I use a damp towel to cover the bowl during autolyse to prevent drying, and I always check dough consistency by pressing my finger in—it should leave a slight indentation but not stick to my skin. 💧
Stretch-and-Folds
Perform 4 sets of stretch-and-folds every 30 minutes for 2 hours—this builds strength without overworking. Wet your hands first to prevent sticking, then grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat in four directions.
After each set, the dough should feel slightly firmer and develop visible gluten strands. If your dough feels too slack after 2 hours, extend the bulk fermentation by 1-2 hours—it’s better to underproof than overproof. 💪
Bulk Fermentation
Ferment at 70-75°F for 4-6 hours, checking readiness with the poke test: gently press your finger into the dough. If it springs back slowly (not immediately), it’s ready. Cooler kitchens? Extend fermentation to 8 hours max—overproofing leads to a dense crumb.
I place my dough in a proofing basket lined with a floured towel to catch any leaks during this stage. The dough should nearly double in size and have a pleasantly tangy aroma from the active starter. ✨
Scoring Secrets
Use a sharp razor or lame for clean cuts—dull tools crush the dough instead of scoring. Dip your tool in ice water before scoring to prevent sticking. For a boule, make a simple cross or basketweave pattern; for a batard, score along the length.
The cut should be deep enough to release steam but not tear the dough. I always practice on scrap dough first to get the tension right—this prevents the loaf from bursting during baking. 🔪
Steam for Crust
Bake covered in a hot Dutch oven for 20 minutes to trap steam, then uncover for 20-25 minutes to develop the crust. The steam creates that crispy, shatterable crust while the uncovered phase ensures even browning.
I place a tray of boiling water on the oven rack below for extra steam if my kitchen is dry. Remove the lid when you see the crust start to golden brown—this is your cue to let it crisp up. 🔥
Cooling Patience
Let the bread cool completely on a wire rack for at least 1 hour—this prevents a gummy crumb. I resist the urge to slice early, even though it’s tempting! The internal temperature should drop below 100°F before cutting.
Store wrapped at room temperature for 3 days or freeze slices for 3 months to preserve freshness. The longer it sits, the more flavor develops—24 hours post-bake is when it truly shines. 🕒

Frequently asked questions
Why does this recipe use 65% hydration instead of higher or lower?
Sixty-five percent hydration offers the perfect balance between structure and openness for sourdough. Lower hydration (60%) creates a tighter crumb, while higher hydration (75%+) risks a weaker structure. This ratio delivers a crispy crust with an open, airy crumb—ideal for slicing and toasting. The whole wheat flour adds just enough density to support the hydration level.
Can I substitute bread flour with all-purpose flour?
Yes, but you’ll need to adjust for lower protein content. Replace all-purpose flour with the same amount of bread flour, then add 1 tbsp vital wheat gluten per cup to mimic the 12-13% protein in bread flour. Without this adjustment, your loaf may develop a denser crumb or weaker structure. For best results, stick with bread flour if possible.
How do I know when my starter is ready for this recipe?
Your starter should be at 100% hydration, bubbly, and have doubled in size within 4-6 hours after feeding. It should also pass the “float test”—drop a small spoonful in water; if it floats, it’s active enough. Feed it 12-24 hours before mixing to ensure peak activity. A tangy aroma is a good sign too!
What if my kitchen is too cold for proper fermentation?
If your kitchen is below 70°F, extend bulk fermentation to 8 hours max or use a proofing box (a container with a lightbulb) to maintain 75-80°F. Never exceed 8 hours—overproofing leads to a dense, gummy crumb. For cold climates, try fermenting near a warm oven with the light on. Always check dough readiness with the poke test.
Why does my bread turn out dense instead of airy?
Dense bread usually results from overproofing, underdeveloped gluten, or insufficient steam during baking. Double-check your bulk fermentation time (should be 4-6 hours at 70-75°F), ensure you performed all 4 stretch-and-folds, and verify your oven has enough steam (use a Dutch oven or boiling water tray). A weak starter can also cause poor rise.
