Ingredients for altamura sourdough bread
Authentic Italian ingredients meet traditional techniques for this signature Altamura sourdough with its iconic crust.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| Type 00 Italian Flour 🌾 | 3 ½ cups | High-protein, 12-14% protein content |
| Filtered Water 💧 | 2 ¼ cups | Room temperature, 75-78°F |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain, sea salt preferred |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For dough handling and scoring |
| All-Purpose Flour 🌾 | ½ cup | For dusting and shaping |
| Aluminum Foil 📄 | 1 sheet | Heavy-duty, for sealed rise |
| Cornmeal 🌽 | ¼ cup | For baking surface preparation |
| Lame Razor ✂️ | 1 whole | For precise dough scoring |
The Type 00 Italian flour is non-negotiable for authentic texture—look for brands like Caputo or Molino Pizzofalcone at specialty stores or online. If unavailable, King Arthur Bread Flour (13% protein) works in a pinch, though texture may differ slightly. Your sourdough starter should be fully active with visible bubbles and a tangy aroma—feed it daily for 5-7 days if reviving from storage. For salt, Diamond Crystal kosher dissolves more easily than table salt, ensuring even distribution in the dough. The olive oil should be extra-virgin and fruity—avoid refined oils that lack flavor complexity.
No Type 00 flour? High-gluten bread flour (14% protein) is the next best option, though it may yield a slightly denser crumb. Running short on starter? 10% of your flour weight in commercial yeast can kickstart fermentation, though flavor will lack the authentic sourdough tang. For scoring, a sharp razor blade or serrated knife works if a lame isn't available—just make deeper cuts to compensate. The foil-sealed rise requires heavy-duty aluminum foil—standard foil tears easily. Substitute with a parchment-lined baking sheet if needed, though texture may vary slightly.
Store active starter in an airtight jar at room temperature, feeding daily with equal parts flour and water. The dough can be shaped up to 24 hours ahead and refrigerated, then proceed with the foil-sealed rise when ready to bake. Freshly baked loaves cool on a wire rack for at least 2 hours to prevent soggy crust. For longer storage, wrap cooled loaves in beeswax wrap or parchment, then place in a bread box—keeps for 3-5 days at room temperature. Freeze unsliced loaves for up to 3 months by wrapping tightly in plastic and foil.
Why You'll Love This Recipe
- Four-Hour Magic: I swear, this bread is done in a fraction of the time I used to spend on baguettes. Just mix the Type 00 flour with your active starter, a splash of filtered water, and a pinch of that flaky kosher salt—no kneading, no fuss. The olive oil finish seals the deal with minimal effort.
- Crusty-Creamy Perfection: That golden crust cracking open? Chef’s kiss. The Type 00’s fine texture gives it a tender crumb, while the sourdough starter’s tang cuts through like a bright, airy whisper. Drizzle it with olive oil while warm, and you’ve got a flavor punch that’ll have you reaching for seconds.
- Weeknight Hero: Between us—this is my go-to for sandwiches, charcuterie boards, or even toasted with tomato and basil. The sourdough’s robustness handles everything from hearty prosciutto to simple jam, and it keeps beautifully for days. (Yes, even on a Tuesday night.)
- Budget-Friendly Staple: A single batch feeds my family for days—think toast, croutons, or even breadcrumbs for dishes. Type 00 flour is affordable, and a well-fed starter means no wasted dough. Plus, homemade always tastes better than store-bought, but costs less than half. Win-win.
Step-by-step instructions for authentic Altamura sourdough bread
This method captures the essence of Puglia's legendary bread—crisp crust, open crumb, and that unmistakable tang.
Autolyse the Dough for Optimal Gluten Development
In a large mixing bowl, combine the 3.5 cups Type 00 Italian Flour with the 2.25 cups Filtered Water at room temperature. Use your hands or a dough whisk to break up any dry pockets, but avoid overmixing. The dough will appear shaggy at first, which is normal. Cover the bowl with a damp kitchen towel and let it rest for 30 minutes at room temperature.
This autolyse stage allows the gluten to begin developing naturally without salt or starter interference. You'll notice the dough gradually become smoother and more cohesive as the flour absorbs the water. The high-protein Type 00 flour creates that signature open crumb structure Altamura bread is known for.
Incorporate Starter, Salt, and Olive Oil
After the autolyse, add the 0.5 cup Active Sourdough Starter to the bowl. Using a dough scraper, gently fold the starter into the outer edges of the dough, working from the bottom up. Sprinkle the 1.5 tsp Diamond Crystal Kosher Salt evenly over the dough, then add the 1 tbsp Extra-Virgin Olive Oil. Continue folding for 5 minutes by hand, turning the dough over itself to incorporate all ingredients uniformly.
The starter should be visibly bubbly and active, indicating proper fermentation. The olive oil adds tenderness while preventing excessive gluten development. You're aiming for a dough that's tacky but not sticky—if it's too wet, add 1 tablespoon of the Type 00 Italian Flour at a time until it reaches the right consistency.
Bulk Fermentation with Controlled Environment
Shape the dough into a loose round and place it back in the bowl. Cover with the damp towel and let it ferment at 75°F (24°C) for 4-6 hours, until it has nearly doubled in volume. I prefer using a proofing box for consistent temperature control, but a warm oven with the light on works too. The dough should feel springy when poked gently—it should leave a slow, deliberate impression rather than bouncing back immediately.
During this time, the starter will continue to ferment, developing that characteristic tang. The dough's surface should show small bubbles and have increased by about 50-75%. If you're working in a cooler environment, extend the fermentation time by 1-2 hours—patience here ensures maximum flavor development. Avoid overproofing, which leads to a dense, gummy crumb.
Final Shape and Foil-Sealed Rise
Lightly dust a clean work surface with 0.25 cup Cornmeal and turn out the dough. Gently shape it into a round boules by pulling the dough toward you in a motion that creates surface tension. For Altamura bread, we'll create a slightly flattened round rather than a tight boule to encourage that characteristic open crumb. Place the shaped dough on a parchment-lined baking sheet.
Cut a 12x12-inch piece from the Aluminum Foil sheet. Place it over the dough and seal tightly around the edges, creating an airtight environment. This sealed rise mimics traditional baking methods in Puglia, where bread was often baked in large quantities. Let the dough rise at 75°F (24°C) for 1-2 hours, until it has expanded to fill about 75% of the foil container. The dough should feel firm but still yield slightly when pressed gently.
Score and Bake for Crisp Crust
Preheat your oven to 450°F (232°C) with a baking stone or inverted baking sheet inside for 45 minutes. Remove the foil from the dough and use the Lame Razor to make 4-6 diagonal cuts about ¼-inch deep, starting from the center and working outward. This creates steam channels that allow the bread to expand properly during baking.
Bake the bread on the preheated stone for 25-30 minutes, rotating the pan halfway through for even browning. The bread is done when it develops a deep golden-brown crust and sounds hollow when tapped on the bottom. The internal temperature should reach 190-200°F (88-93°C). For maximum crispness, transfer the bread to a wire rack and let it cool for 10 minutes before slicing.
Pro Tips For Making Altamura Sourdough Bread
- Use Room-Temp Flour: Altamura’s low hydration works best when your Type 00 flour is at room temperature—about 70°F (21°C). I used to skip this and ended up with a denser crumb, like my dough was fighting me the whole time. Weigh it out first, then let it sit in a bowl for 30 minutes while you prep.
- Shape Tight, Score Deep: The secret to that iconic Altamura crust isn’t just steam—it’s tension. Stretch your dough into a taut rectangle before scoring, and cut the slashes all the way through with a razor. Shallow cuts mean weak spots that tear open too soon, and nobody wants a sad, uneven bake.
- Salt the Water Hard: Diamond Crystal kosher salt dissolves slower than table salt, so use 1.5 teaspoons per 500g of water (yes, more than the recipe says). I learned this after my first loaf tasted bland—turns out, "just add salt" isn’t enough when you’re working with a delicate starter. Taste the water before mixing; it should be noticeably salty.
- Bake with a Lid First: Preheat your Dutch oven and place a metal lid (or baking sheet) inside for 20 minutes. When you add the dough, cover it immediately—this traps steam longer than steamers alone. I tried skipping this once, and the crust never got that crisp, blistered edge. Sounds weird, but it works.
Make-ahead tips for this altamura sourdough bread
Starter Prep Ahead
Create your sourdough starter 5-7 days before baking to ensure it's robust and active. Store it in an airtight jar at room temperature, feeding it daily with equal parts Type 00 Italian flour and filtered water.
The starter should be fully bubbly with a tangy aroma before using—this means it's ready to deliver that authentic Altamura tang. I keep mine on the counter near my oven for consistent warmth. 💫
Dough Pre-Shaping
Shape your dough into a loose round up to 24 hours ahead and refrigerate it in an airtight container. When you're ready to bake, simply remove it from the fridge and proceed with the foil-sealed rise at room temperature.
This slow cold fermentation enhances flavor development and makes the dough easier to handle when warm. I often prep dough the night before for a stress-free morning baking session.
Foil-Sealed Rise Flexibility
The foil-sealed rise can be done at room temperature for 1-2 hours or extended to 4-6 hours in the refrigerator for a slower, more flavorful development. If refrigerating, let the dough sit at room temperature for 30-60 minutes before scoring and baking to ensure even expansion.
The foil creates a steam chamber that mimics traditional wood-fired ovens, giving you that signature crisp crust without burning. 🔥
Baking in Batches
Make two loaves at once by dividing the dough into equal portions before shaping. Use two parchment-lined baking sheets and foil-seal each separately. Bake them simultaneously for efficiency, rotating pans halfway through.
Store any extra loaves in a bread box or beeswax wrap to maintain freshness for up to 5 days. For longer storage, freeze baked loaves wrapped tightly in plastic and foil for up to 3 months.
Reviving Stale Bread
To refresh slightly stale Altamura sourdough, wrap it in aluminum foil and reheat in a 350°F (175°C) oven for 5-10 minutes. The heat will revive the crust while keeping the interior soft.
For a quicker fix, place the bread in a paper bag and microwave for 10-15 seconds—this method works best for toasting slices. I always keep a loaf on hand for quick bruschetta or soup dipping. ✨
Freezer-Friendly Dough
Shape your dough, wrap it tightly in plastic, and freeze it for up to 1 month. When ready to bake, thaw the dough in the refrigerator overnight, then proceed with the foil-sealed rise as directed.
This method is perfect for busy schedules—just pull it out in the morning and bake by lunchtime. The dough's flavor remains vibrant after freezing, though the texture may be slightly denser. 💡

Frequently asked questions
Why does Altamura sourdough bread need a foil-sealed rise?
The foil-sealed rise creates a steam chamber that mimics traditional wood-fired ovens in Puglia. This method produces the bread's signature crisp crust without burning while developing that open, airy crumb structure. The sealed environment also helps control fermentation speed, giving you consistent results even in cooler kitchens.
Can I substitute Type 00 flour with regular all-purpose flour?
While you can use all-purpose flour, it won't give you the same authentic texture. Type 00's 12-14% protein content creates that signature open crumb. For best results, use high-gluten bread flour (14% protein)—just expect a slightly denser crumb. The flavor will still be delicious, though!
How do I know when my sourdough starter is ready for Altamura bread?
Your starter should be fully bubbly with a tangy aroma (like yogurt or vinegar) and double in size within 4-6 hours after feeding. It should also float in water—drop a spoonful in a glass of water and if it stays afloat, it's ready! This ensures maximum flavor development in your bread.
Why did my Altamura bread turn out dense instead of airy?
Dense bread usually means overproofing or insufficient gluten development. Check your fermentation time—the dough should be 50-75% larger but still springy, not collapsing. Also ensure you're using high-protein flour and autolysing properly. If your kitchen is cool (below 70°F/21°C), extend bulk fermentation by 1-2 hours for better rise.
What's the best way to store leftover Altamura sourdough?
Wrap cooled loaves in beeswax wrap or parchment and store at room temperature in a bread box for 3-5 days. For longer storage, freeze sliced bread (wrapped tightly) for up to 3 months. To revive stale bread, reheat at 350°F (175°C) for 5-10 minutes or toast slices in a paper bag.
