If you’ve ever wondered whether Italian 00 flour can improve your sourdough discard pizza dough, the answer is yes—but not for the reasons most people think.
If you’re still deciding which flour to use, see our complete guide to the best flour for sourdough pizza.
Many home bakers switch to 00 flour expecting instant pizzeria-quality results. Sometimes they get them. Other times they end up with a dough that’s too soft, difficult to handle, or surprisingly lacking in chew.
The secret is understanding how 00 flour behaves differently from bread flour and how fermentation affects the final crust.
If you’re looking for the complete master recipe, start with our sourdough discard pizza dough guide. This article focuses specifically on using Italian 00 flour and how it changes dough behavior, hydration, fermentation, and crust texture. This article focuses specifically on using Italian 00 flour and how it changes dough handling, hydration, fermentation, and baking performance.
What Is 00 Flour?
00 flour refers to how finely the flour is milled rather than its protein content.
Italian flours are graded from 2, 1, 0, and 00, with 00 being the finest grind available. The result is an incredibly soft flour that produces smooth, extensible dough.
One of the biggest misconceptions is that all 00 flour is low protein. In reality, pizza-specific 00 flours often contain protein levels similar to bread flour.

Can You Use Sourdough Discard With 00 Flour?
Absolutely.
Sourdough discard and 00 flour work exceptionally well together because the fine texture of 00 flour complements the longer fermentation associated with sourdough baking.
The dough becomes easier to stretch, develops excellent extensibility, and often produces a lighter crust than bread flour alone.
Whether you’re using active starter or discard, both can create excellent pizza. If you’re unsure which one is best for your schedule, compare sourdough discard vs active starter pizza.
Why Many Pizza Makers Prefer 00 Flour
There are four major reasons serious pizza makers choose 00 flour:
Easier Stretching
The fine milling produces a silky dough that stretches more easily than many bread flour doughs.
Better Leopard Spotting
At high temperatures, 00 flour often develops the blistered spotting associated with traditional Neapolitan pizza.
Softer Interior Crumb
Many bakers find the interior texture lighter and more open.
Better High-Heat Performance
00 flour excels in pizza ovens operating above 700°F.
00 Flour vs Bread Flour
This is where many bakers get stuck.
Can You Mix 00 Flour and Bread Flour?
Yes. Many experienced pizza makers combine 50% bread flour and 50% 00 flour to get the best characteristics of both. Bread flour contributes strength and chew while 00 flour improves extensibility and produces a lighter, more delicate crust.
This blend is particularly useful for home ovens that cannot reach traditional Neapolitan temperatures because it helps maintain structure while still delivering many of the benefits associated with Italian 00 flour.
Bread Flour Advantages
- Stronger gluten development
- More chew
- Better support for heavy toppings
- Easier for beginners
00 Flour Advantages
- More extensible dough
- Easier shaping
- Authentic Neapolitan texture
- Better high-heat performance
Neither flour is objectively better.
They simply produce different styles of pizza.
Best Hydration for Sourdough Discard Pizza Dough With 00 Flour
Hydration becomes even more important when using 00 flour.
Most bakers get the best results between 65% and 70% hydration.
- 65% hydration = easiest handling
- 68% hydration = ideal balance
- 70% hydration = maximum extensibility
If hydration percentages still seem confusing, read our complete guide to sourdough hydration explained.
Does 00 Flour Work Better With Long Fermentation?
In most cases, yes.
Longer fermentation allows the gluten network to organize more completely while giving beneficial bacteria and yeast additional time to develop flavor.
Many pizza makers believe the biggest advantage of 00 flour appears during cold fermentation.

How To Stretch 00 Flour Pizza Dough
One reason bakers fall in love with 00 flour is how easy it becomes to stretch properly fermented dough.
The dough typically offers less resistance than bread flour dough and develops a silky feel that’s difficult to achieve with standard flour blends.
To prevent tearing:
- Allow sufficient fermentation.
- Let refrigerated dough warm slightly before stretching.
- Press outward from the center.
- Avoid rolling pins.
- Let gravity do the work.
If your dough tears during shaping, see our guide on stretching sourdough discard pizza dough without tearing.
Common Problems With 00 Flour Pizza Dough
Dough Feels Too Sticky
Many bakers assume the solution is adding flour.
Usually it isn’t.
The real causes are:
- Excess hydration
- Underdeveloped gluten
- Insufficient fermentation
- Warm dough temperatures
If you’re struggling with stickiness, see how to fix sticky sourdough discard pizza dough.
Dough Tears While Stretching
This often indicates:
- Under-fermentation
- Weak gluten structure
- Dough that is still too cold
Many stretching problems disappear when fermentation improves.

Crust Isn’t Crispy
Flour is rarely the culprit.
The biggest factors are:
- Oven temperature
- Stone or steel preheat
- Fermentation quality
- Dough hydration
For maximum crispness, follow the techniques in our guide to crispy sourdough discard pizza crust.
Best Baking Temperature for 00 Flour Pizza
Home Oven
- 500–550°F
- Preheated pizza steel
- 6–10 minute bake
Ooni or Pizza Oven
- 700–900°F
- 60–120 second bake
This is where 00 flour truly shines.
The combination of fine milling and extreme heat creates the blistering and leopard spotting associated with traditional Neapolitan pizza.
Frequently Asked Questions
Can I substitute 00 flour for bread flour in sourdough discard pizza dough?
Yes. Most recipes can be converted directly, although minor hydration adjustments may improve handling.
Is 00 flour better than bread flour?
It depends on your goal. Bread flour creates more chew while 00 flour creates greater extensibility and a more traditional Neapolitan texture.
What hydration is best for 00 flour pizza dough?
Most bakers achieve the best balance between handling and extensibility at 65–70% hydration.
Can you use sourdough discard with 00 flour?
Absolutely. Sourdough discard and 00 flour work exceptionally well together and can produce outstanding pizza.
Can you mix 00 flour and bread flour for pizza dough?
Yes. Many bakers use a blend of 00 flour and bread flour to combine the extensibility of 00 flour with the strength and chewiness of bread flour.
Final Thoughts
Sourdough discard pizza dough with 00 flour offers one of the easiest ways to elevate homemade pizza.
The dough stretches beautifully, performs exceptionally well during long fermentation, and produces the airy crust many bakers chase for years.
