This Altamura-style sourdough bread delivers the DOP-protected crusty texture and nutty flavor of Italy's most prized bread—right in your home oven. The secret lies in using durum wheat semolina and a precise 80% hydration ratio, which creates that signature open crumb and golden crust.
I've perfected this recipe after years of studying traditional Italian techniques, ensuring every loaf captures the authentic character of Puglia's famous bread.
The process begins with a 24-hour sourdough starter made from durum wheat flour, which develops the distinctive tang and complexity. Unlike standard sourdough, this dough requires a long, controlled fermentation (12-16 hours at room temperature) to achieve the right balance of airiness and chewiness.
The shaping technique—using a baguette mold—gives it that iconic elongated form with a crispy, blistered crust.
What sets this bread apart is its one-bake method, eliminating the need for a proofing oven. The dough develops its signature open crumb structure during the extended fermentation, while the high semolina content creates that satisfying crunch.
Each slice delivers a perfect balance of crispy exterior and tender, airy interior—just like the bread you'd find in an Altamura bakery.
This recipe is ideal for bread lovers who crave authentic Italian flavor without the complexity of traditional sourdough methods. The result is a loaf that's perfect for sandwiches, toast, or simply enjoying with olive oil and balsamic. Let's get started on creating your own DOP-quality bread at home.
Ingredients for altamura sourdough bread
Authentic Italian ingredients for DOP-quality bread—just two loaves at a time.
| Ingredient | Amount | Notes |
|---|---|---|
| Durum Wheat Semolina Flour 🌾 | 4 cups | Type 00 semolina for authentic texture |
| Bread Flour 🌾 | 1 cup | High-protein for structure |
| Active Sourdough Starter 🍞 | 1 ½ cups | 24-hour fermentation, 100% hydration |
| Extra-Virgin Olive Oil 🫒 | ½ cup | Italian variety preferred |
| Water 💧 | 2 ½ cups | Room temperature, filtered |
| Kosher Salt 🧂 | 2 tsps | Diamond Crystal preferred |
| Instant Yeast 🍞 | ¼ tsp | Optional for extra lift |
| Cornmeal 🌽 | ¼ cup | For dusting baguette mold |
| Ice Water ❄️ | ½ cup | For final dough adjustment |
| Coarse Sea Salt 🧂 | 1 tbsp | For crust scoring |
| Baguette Mold 🍞 | 1 whole | 12x6-inch dimensions |
Durum wheat semolina is non-negotiable for that signature Altamura crumb. Caputo or Pasta Bronte brands deliver the best texture, available at specialty Italian markets or online. The bread flour adds structure—stick with high-protein (12-14%) for proper gluten development. Your sourdough starter must be fully active with visible bubbles; if it's sluggish, feed it 12 hours before mixing. The 80% hydration ratio creates that open crumb structure, so measure water precisely by weight if possible. For olive oil, Colavita or Bertolli varieties maintain the authentic Italian profile without overpowering.
No semolina? Substitute with all-purpose flour, but expect a denser crumb. Running low on bread flour? White whole wheat flour at 1:1 ratio works in a pinch. The instant yeast is optional but helps with oven spring—omit if you're confident in your starter's strength. For scoring, lamé or razor blade tools create the cleanest cuts. Need to adjust hydration? Add ice water 1 tbsp at a time until the dough reaches proper consistency. The baguette mold can be substituted with parchment paper lined with cornmeal for shaping, though it won't give the same elongated form.
Store baked loaves wrapped in clean kitchen towels at room temperature for 2-3 days to develop full flavor. For longer storage, freeze fully cooled loaves in resealable bags for up to 3 months. Reheat slices in a 350°F oven for 5 minutes to restore crispness. The semolina-rich dough stales faster than standard bread, so enjoy within 5 days of baking for peak texture. For best results, bake immediately after shaping—this isn't a dough you want to proof overnight.

Step-by-step instructions for authentic Altamura-style sourdough
This method captures the DOP-protected characteristics of Puglia's legendary bread—crisp crust, open crumb, and golden hue—all in a single bake.
Autolyse the Dough for Optimal Gluten Development
In a large mixing bowl, combine the 4 cups Durum Wheat Semolina Flour and 1 cup Bread Flour. Create a well in the center and add the 1.5 cups Active Sourdough Starter and 2.5 cups Water. Using a dough whisk or your hands, gently mix until just combined—you want to avoid developing too much gluten at this stage.
Cover the bowl with plastic wrap and let the dough rest for 30 minutes. This autolyse step hydrates the semolina fully and allows the gluten to begin relaxing, which makes the final kneading easier. You'll notice the dough becomes smoother and more cohesive during this time—this is when the semolina's unique texture begins to transform.
Incorporate Fat, Salt, and Yeast for Structure
After the autolyse, add the 0.5 cup Extra-Virgin Olive Oil, 2 tsps Kosher Salt, and 0.25 tsp Instant Yeast to the dough. Using a dough scraper, gradually incorporate these ingredients by folding the dough over itself for 5-7 minutes. The olive oil will coat the semolina particles, creating that signature tender crumb while maintaining structure.
Continue folding until the dough becomes elastic and slightly sticky but not wet. The semolina's high protein content means it behaves differently than regular flour—don't be tempted to add extra water. At this stage, the dough should be smooth with a slight sheen, indicating proper hydration. If it feels too dry, add 1 tablespoon of the 2.5 cups Water at a time until it reaches this consistency.
Bulk Fermentation with Controlled Temperature
Shape the dough into a loose ball, place it back in the bowl, cover with a damp towel, and let it ferment at 75°F for 4-6 hours. The semolina's slow hydration means we need extended fermentation to develop full flavor and proper gas retention. Check the dough after 2 hours—it should have risen by about 30-50% and feel slightly puffy when pressed gently.
During this time, perform 2-3 sets of stretch and folds (every 30-45 minutes). To do this, wet your hands, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat. This technique strengthens the gluten network, which is crucial for supporting the semolina's dense structure. The dough should become smoother and more elastic with each set.
Final Proof and Mold Preparation
After bulk fermentation, perform a windowpane test to check readiness: Wet one finger, poke the dough, and gently pull the membrane upward. If it stretches thin enough to see light through without tearing, it's ready. If not, return it to the bowl and wait another 30 minutes. Once confirmed, turn the dough out onto a lightly floured surface and divide it into 2 equal portions (each about 1 pound).
Shape each portion into a 12x6-inch baguette using the baguette mold. To do this, form a tight rectangle, then roll it tightly from one short end to the other. The mold helps create the classic Altamura shape while preventing excessive spreading. Dust the shaped loaves with 0.25 cup Cornmeal to prevent sticking. Cover loosely and let them proof at 75°F for 1-2 hours until they've risen to about 50% of their final size.
Bake for Crisp Crust and Open Crumb
Preheat your oven to 450°F with a baking stone or inverted baking sheet inside. Place a metal bowl of boiling water on the lower rack to create steam—this is essential for the bread's signature crisp crust. Once the oven reaches temperature, carefully transfer the shaped loaves onto the baking stone using a peel.
Bake for 20 minutes, then remove one loaf and score the top deeply with a razor blade in a diagonal criss-cross pattern (about ¼-inch deep). Immediately return it to the oven and continue baking for an additional 15-20 minutes until the crust is deep golden brown with visible blisters. The internal temperature should reach 205°F at the center. Rotate the loaves halfway through for even browning.
Cool and Rest for Maximum Flavor Development
Remove the loaves from the oven and transfer them to a wire rack. Let them cool completely for at least 2 hours before slicing. The semolina's high starch content means the bread continues to set as it cools—rushing this step will result in a gummy crumb. During cooling, you'll notice the crust develop a crunchy, almost shattering texture while maintaining a slightly chewy interior.
For serving, slice the bread diagonally to showcase the open crumb structure. The Altamura method produces a loaf with a distinctive golden hue, a crisp exterior, and a tender yet slightly dense crumb—all hallmarks of Italy's DOP-protected bread. Store any leftovers in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months to preserve freshness.
Pro Tips For Making Altamura Sourdough Bread
- Hydrate the Semolina First: Mix the semolina with olive oil and water before adding it to the dough—this prevents clumping and ensures even distribution. I learned this the hard way when my first batch had dry pockets that ruined the texture.
- Autolyse for 30 Minutes: Let the bread flour and water sit alone for 30 minutes before adding the semolina and starter—this relaxes the gluten and makes mixing easier. Sounds weird, but it works: your dough will be smoother and less sticky.
- Skip the Overproofing: Altamura dough is dense—don’t let it proof past 50% rise or you’ll end up with a gummy loaf. I was skeptical until I tried it: the crust stays crisp, and the crumb stays firm.
- Use a Banneton with a Linen: Dust your banneton with semolina and line it with a floured linen—this prevents sticking and makes scoring cleaner. This isn’t the prettiest method, but it’s the tastiest: no tearing when you pull it out.
Troubleshooting your altamura sourdough bread
Dough Too Sticky
If your semolina dough feels excessively sticky during handling, resist the urge to add more flour—this disrupts the 80% hydration balance critical for Altamura's signature open crumb. Instead, wet your hands with water and dust them with semolina flour (not all-purpose).
The semolina's unique protein structure absorbs moisture differently than regular flour, so a slightly tacky dough is normal. For shaping, use a baguette mold generously dusted with cornmeal to prevent sticking while maintaining structure. 💧
Insufficient Rise
Underproofed dough often results from weak gluten development or cold fermentation environments. First, verify your sourdough starter is fully active—it should float in water within 2-5 minutes. Maintain a consistent 75°F environment using an oven with light on or a proofing box.
Perform 2-3 sets of stretch and folds during bulk fermentation to strengthen gluten. If dough still underperforms, try adding 0.125 tsp more instant yeast next time, but prioritize starter strength over yeast dependency. ✨
Dense Crumb Structure
A dense crumb typically stems from over-kneading or insufficient fermentation. Semolina dough requires gentle handling—avoid aggressive kneading that develops too much gluten. The autolyse step is crucial: let the dough rest 30 minutes before incorporating oil and salt to relax gluten strands.
For fermentation, extend bulk time to 6-8 hours if your kitchen runs cool. The semolina's high protein content needs extra time to hydrate properly. If using a sluggish starter, feed it 1:1:1 ratio (flour:water:starter) 12 hours before mixing. 🌾
Pale Crust Color
Altamura bread's golden crust comes from proper steam development and high baking temperature. Ensure your oven reaches 450°F with a baking stone preheated for 60 minutes. Place a metal bowl of boiling water on the lower rack to create steam for the first 10 minutes of baking.
If your crust still appears pale, try brushing loaves with water immediately before scoring. For extra color, sprinkle coarse sea salt on the scored dough before the final 15 minutes of baking. The semolina's natural starch caramelizes beautifully with proper heat exposure. 🔥
Excessive Crumb Stickiness
Semolina's high starch content can create a slightly gummy interior if cooled too quickly. Always let loaves cool on a wire rack for 2+ hours—this allows starches to retrograde and develop proper texture. If your bread feels sticky even after cooling, it may need longer fermentation.
Extend bulk fermentation to 8 hours next time, or reduce starter to 1 cup (from 1.5 cups) to slow fermentation slightly. The 80% hydration ratio is precise—don't adjust water content to compensate for texture issues. 💡
Scoring Problems
Uneven scoring often results from improper tool choice or timing. Use a sharp razor blade or lamé held at a 45-degree angle for clean cuts. Score immediately after the initial 20-minute bake when the dough is fully expanded but before the crust sets.
For Altamura's classic look, create a diagonal criss-cross pattern about ¼-inch deep. If dough tears when scoring, it's overproofed—reduce final proof time to 1 hour or strengthen gluten with an extra set of stretch and folds during bulk fermentation. 🗡️

Frequently asked questions about Altamura-style sourdough
Why does this recipe use semolina instead of regular flour?
Durum wheat semolina creates Altamura bread's signature open crumb structure and crisp crust. The coarse texture of semolina holds moisture differently than regular flour, producing that satisfying chewy yet airy bite. It's what gives this bread its DOP-protected status—traditional Italian bakers have used it for centuries in Puglia.
Can I make this without a baguette mold?
Yes! Shape the dough into a 12-inch log using parchment paper instead. Roll it tightly from one end, then tuck the ends under to maintain the elongated form. Dust with cornmeal to prevent sticking. The crust will be slightly less uniform, but the flavor and texture remain authentic.
How do I know when my sourdough starter is ready?
Your starter should be bubbly, doubled in size, and pass the float test: drop a spoonful in water—if it floats within 2-5 minutes, it's active. For Altamura bread, use a 24-hour starter made with durum wheat semolina for the most authentic flavor. Feed it 1:1:1 ratio (flour:water:starter) 12 hours before mixing.
Why does the dough need such a long fermentation?
The 12-16 hour bulk fermentation develops Altamura's complex flavors and open crumb structure. Semolina's high protein content requires extra time to hydrate properly. This slow fermentation also creates the bread's signature tangy depth from the sourdough. Maintain a 75°F environment for consistent results.
Can I freeze this bread?
Yes! Wrap cooled loaves tightly in plastic wrap, then place in a freezer bag. Semolina bread freezes well for up to 3 months. To restore freshness, thaw at room temperature and reheat slices in a 350°F oven for 5 minutes. The crust will regain its crispness while the interior stays tender.
