Ingredients for altamura sourdough bread
Authentic Altamura sourdough begins with these eight essential ingredients—each playing a crucial role in crafting that legendary Italian crust.
| Ingredient | Amount | Notes |
|---|---|---|
| Type 00 Flour 🌾 | 4 cups | Italian 00 flour preferred for authenticity |
| Active Sourdough Starter 🍞 | 1 cup | 100% hydration, bubbly and active |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Italian preferred for authentic flavor |
| Sea Salt 🧂 | 1 ½ tsp | Fine grain preferred, Diamond Crystal ideal |
| Water 💧 | 1 ½ cups | Room temperature, filtered preferred |
| Semolina Flour 🌾 | ¼ cup | For dusting and crust development |
| Cornmeal 🌽 | ¼ cup | For baking sheet surface |
| Coarse Sea Salt 🧂 | ½ tsp | For crust scoring and finishing |
The flour is non-negotiable here. Italian 00 flour has the low protein content that creates Altamura's signature dense crumb, but King Arthur Bread Flour works in a pinch. I source mine from Eataly or Amazon for authenticity, but any high-quality bread flour will do. Your sourdough starter should be at peak activity—100% hydration with visible bubbles when dropped in water. For the olive oil, Colavita or Bertolli brands deliver that authentic Italian flavor profile. The sea salt? Diamond Crystal is my go-to for fine grain, but any pure sea salt works. Room temperature water is critical—cold water slows fermentation, ruining the bread's structure.
No Italian 00 flour? King Arthur Bread Flour plus 1 tbsp vital wheat gluten mimics the protein structure. Short on semolina? All-purpose flour works too, though it won't crisp as beautifully. The coarse sea salt for scoring can be swapped for kosher salt if that's what you have. For the starter, if yours isn't ready, you can use 1 packet active dry yeast plus 1 tbsp sugar as a temporary substitute (though true Altamura flavor requires sourdough). The olive oil can be omitted entirely if you're avoiding fat, but it's worth including for that signature Italian richness. And if you're baking in a humid climate, reduce water by 1 tbsp to prevent gummy dough.
Store your sourdough starter in the fridge between uses—it'll keep for up to 2 weeks. For the flour, keep it airtight in a cool pantry for up to 6 months. Once baked, Altamura bread is best enjoyed the same day, but slices well for 3-4 days if wrapped tightly. For reheating, wrap slices in foil and warm in a 350°F oven for 5 minutes. The crust loses crispness quickly, so always bake fresh batches when possible. Freeze dough balls for up to 3 months if you want to bake ahead—just let them rise at room temperature before baking.

Step-by-step instructions for authentic Altamura sourdough bread
Here's how to capture that legendary Italian crust with a tangy, open crumb—just like the bread that earned Altamura its UNESCO designation.
Autolyse the Dough for Maximum Development
In a large mixing bowl, combine the 4 cups Type 00 Flour and 1.5 cups Water at room temperature. Use your hands or a dough whisk to break up any dry patches until you have a shaggy, sticky mass. This initial mix is called an autolyse, and it kickstarts gluten development while hydrating the flour evenly.
Cover the bowl with a damp towel and let it rest for 30 minutes. You'll notice the dough become smoother and more elastic as the flour absorbs the water. This resting period is crucial—it creates a more extensible dough that opens beautifully in the oven, just like traditional Altamura bread.
Incorporate Starter, Oil, and Salt
After the autolyse, add the 1 cup Active Sourdough Starter and the 0.25 cup Extra-Virgin Olive Oil to the bowl. Using a dough scraper, gently fold these ingredients into the dough until fully incorporated. The oil will help create that characteristic tender crumb while contributing subtle fruity notes.
Next, sprinkle the 1.5 tsp Sea Salt evenly over the dough. Dimple your fingers into the dough to work the salt into the center. This technique ensures even distribution without overworking the gluten. Let the dough rest for another 30 minutes before beginning the stretch-and-fold routine.
Perform Stretch-and-Folds for Structure
Wet your hands to prevent sticking, then grab one side of the dough and stretch it upward while folding it over itself. Rotate the bowl and repeat this process four times, working all sides of the dough. This builds strength and elasticity without over-developing the gluten.
Repeat the stretch-and-folds every 30 minutes for a total of 2 hours. You'll know you're on the right track when the dough becomes smoother, more resistant, and develops a slight sheen on the surface. This method mimics traditional Italian dough handling techniques that create that signature open crumb structure.
Bulk Ferment and Shape the Loaves
After the final stretch-and-fold, let the dough rest for 30 minutes before dividing it into two equal portions. Shape each piece into a tight boule by pulling the edges toward the center and sealing the seam. Place the shaped loaves on a floured surface, seam-side up, and cover with a damp towel.
Let the dough undergo a 2-3 hour bulk fermentation at room temperature until it has nearly doubled in size and shows good activity at the seams. The dough should feel springy when poked gently—this indicates proper fermentation. For best results, maintain a consistent temperature around 75°F during this stage.
Final Proof and Bake for Crispy Crust
Preheat your Dutch oven with lid in a 475°F oven for 45 minutes. While it heats, score the loaves with a razor blade using a crosshatch pattern, then sprinkle generously with 0.5 tsp Coarse Sea Salt. This scoring prevents over-expansion and creates those beautiful crust patterns.
Carefully transfer the loaves to the hot Dutch oven, cover, and bake for 20 minutes. Then remove the lid and bake for another 15-20 minutes until the crust reaches a deep golden brown. The internal temperature should reach 205°F at the center. Let the bread cool on a wire rack for at least 1 hour before slicing—this ensures proper crust development and prevents a gummy interior.
Pro Tips For Making Altamura Sourdough Bread
- Weigh Your Starter Precisely: Altamura bread relies on that sourdough starter’s strength—too much or too little throws off hydration and rise. Use a digital scale to measure it to the gram (I’ve ruined batches by eyeballing it), and aim for 10-15% of your total flour weight. A balanced starter means a lighter, airier crumb, not a dense brick.
- Autolyse First, Always: Mix the Type 00 flour and water before adding starter or salt—this resting step (20-30 minutes) lets gluten relax and develop more evenly. I used to skip it, thinking it wasted time, but now I see the difference: a smoother dough that handles shaping like butter, not a stubborn lump.
- Score Deep, Score Fast: Use a razor blade or very sharp knife to slash the loaf—shallow cuts won’t steam properly, and deep ones risk tearing. Work quickly: once you slash, get it in the oven within 10 seconds. Hesitate, and the dough will start sealing itself shut, ruining that perfect oven spring.
- Upgrade with Olive Oil: Altamura’s signature flavor comes from the olive oil—don’t skimp. Use 1-2 tablespoons of good extra-virgin (the kind you’d drizzle on pasta), and add it to the dough after the autolyse but before the starter. It keeps the crumb tender and adds a subtle fruity note that cheap oil can’t match. (Yes, even if you’re not a fan of olive oil in bread.)
Dietary considerations for altamura sourdough bread
Gluten-Free Adaptations
Altamura bread's signature texture comes from its low-protein flour, but you can adapt it for gluten-free diets using a 1:1 gluten-free flour blend like King Arthur Measure for Measure or Bob's Red Mill 1-to-1.
Replace the 4 cups Type 00 flour with 4 cups gluten-free blend, then add 1 tbsp xanthan gum to mimic gluten's structure. Increase water by 2 tbsp—gluten-free dough tends to be drier. Ferment time may extend to 3-4 hours due to slower gluten development. 🌾
Vegan-Friendly Options
The original recipe uses extra-virgin olive oil and sea salt, both naturally vegan, but traditional sourdough starter contains honey. Replace it with a vegan sourdough starter made from flour and water only—feed it with equal parts flour and water daily.
For extra tang, add 1 tsp apple cider vinegar to the starter. The flavor will develop similarly over 5-7 days. No other adjustments are needed—this maintains the bread's authentic profile.
Lower-Carb Modifications
To reduce carbs, replace 2 cups of Type 00 flour with 2 cups almond flour or coconut flour. Note that coconut flour absorbs 10x its volume in liquid, so reduce water by 1 cup initially. Add 1 extra egg (or 1 tbsp psyllium husk) for binding.
Ferment time may shorten to 1.5-2 hours—monitor closely. Expect a denser, sweeter bread with less open crumb. For best results, use a Dutch oven with steam to compensate for reduced gluten structure. 💪
Allergen-Free Considerations
For nut allergies, avoid almond flour substitutions and stick to certified gluten-free blends. Egg-free versions work with 1 tbsp flaxseed meal + 3 tbsp water per egg replaced. Always check labels on sea salt (some contain anti-caking agents with allergens) and olive oil (rare, but some brands process with soy).
When using semolina or cornmeal for dusting, verify they're processed in allergen-free facilities. Cross-contamination risks are highest with shared kitchen tools—wash everything thoroughly between batches.
Keto-Friendly Adjustments
Creating a keto version requires radical changes: replace all flour with 1 cup finely ground psyllium husk (mixed with 1 cup almond flour) and 1 tbsp vital wheat gluten (for structure). Use 3 eggs as binders and reduce water to 1 cup.
Ferment for only 1 hour—keto doughs ferment faster. Bake at 375°F for 30-35 minutes in a Dutch oven to prevent burning. Expect a dense, cake-like texture with minimal open crumb. Net carbs will be ~3g per slice—prioritize portion control. 🥖

Frequently asked questions
Why does Altamura sourdough need such a long fermentation?
The extended 2-3 hour bulk fermentation develops the bread's signature tangy flavor and open crumb structure. This slow process allows natural yeasts in the sourdough starter to break down starches into sugars, creating complex flavors and a lighter texture. Traditional Italian bakers use this method to achieve the bread's characteristic chewiness and crisp crust.
Can I make this bread without a Dutch oven?
Yes, but you'll need to create steam for proper crust development. Place a baking sheet on the oven rack below your loaf pan, then pour 1 cup hot water into it when baking. This mimics the steam of a Dutch oven and helps create that crispy crust. Bake at 475°F for 25-30 minutes total, rotating the pan halfway for even browning.
How do I know when my sourdough starter is ready?
Your starter should float in water (the "float test") and have visible bubbles when dropped in water. It should also double in size within 4-6 hours after feeding. For Altamura bread, aim for a starter that's 100% hydration (equal parts flour and water) and has a slightly tangy, yeasty aroma. Feed it daily with equal parts flour and water for best results.
Why did my bread turn out dense instead of open-crumb?
This usually happens from either underproofing (not enough fermentation time) or overworking the dough during mixing. For Altamura, focus on gentle handling during stretch-and-folds and ensure your bulk fermentation reaches 2-3 hours at 75°F. Also check your flour—Italian 00 has lower protein content which creates that signature dense yet open crumb.
How should I store Altamura sourdough?
Wrap cooled loaves tightly in plastic wrap or place in a bread box to maintain freshness. Store at room temperature for 3-4 days or freeze dough balls for up to 3 months. For reheating, wrap slices in foil and warm in a 350°F oven for 5 minutes to restore crust crispness. Never refrigerate—this makes bread stale faster.
