As home pizza makers, we’re always on the hunt for that perfect Neapolitan-inspired crust – airy yet chewy, with a complex flavor profile that transports us to the streets of Naples. Two key players in achieving this elusive balance are the age-old techniques of biga and poolish.
In the world of pizza dough, these pre-ferments are like the yin and yang, each offering its own unique advantages. Let’s dive in and explore the differences between biga and poolish, and how they can help you take your homemade pizza to new heights.
Understanding Poolish and Biga
At their core, both biga and poolish are pre-ferments – mixtures of flour, water, and a small amount of yeast or sourdough starter that are allowed to ferment before being incorporated into the final dough. The primary distinction lies in their hydration levels.
- Poolish: A high-hydration (around 100%) pre-ferment, meaning it has equal parts flour and water.
- Biga: A lower-hydration (around 60-70%) pre-ferment.
This difference in water content can have a significant impact on the final dough. The role of these pre-ferments is to kick-start the fermentation process, allowing enzymes to break down complex starches and proteins, enhancing both flavor and texture in the final pizza crust.
Flavor Development
When it comes to flavor, biga and poolish each impart their own unique stamp.
- Biga: With its lower hydration, biga tends to produce a more pronounced sour note in the dough, thanks to the increased activity of lactic acid-producing bacteria. This can result in a deeper, more complex flavor profile.
- Poolish: Leans more towards a subtle, yeasty sweetness, with a slightly milder acidity. The higher hydration levels can also contribute to a more pronounced “crust” flavor, as the evaporation of water during baking concentrates the Maillard reaction-derived compounds.
Texture and Crumb Structure
The differing hydration levels of biga and poolish also play a role in the texture and crumb structure of the final pizza crust.
- Biga: Can produce a chewier, more structured crust, with a more irregular, “holey” crumb structure.
- Poolish: Often results in a lighter, airier texture, with a more uniform, open crumb.
These textural differences can impact the overall mouthfeel and experience of your homemade Neapolitan-style pizza.
Handling and Baking Differences
When it comes to working with the dough, biga and poolish also present some notable differences.
- Biga-based doughs: Can be a bit more challenging to handle, as the lower hydration can make them stiffer and less extensible. During baking, they often exhibit a more pronounced oven spring, resulting in a taller, loftier crust.
- Poolish-based doughs: Are generally more relaxed and easier to stretch and shape. They may spread a bit more during baking, leading to a slightly flatter yet more tender and airy final product.
Pros and Cons
Both biga and poolish have their advantages and disadvantages when it comes to making Neapolitan-style pizza at home.
- Biga: Offers a more intense flavor profile and a chewier texture but requires more planning and skill to execute properly.
- Poolish: A bit more beginner-friendly, can produce a lighter, more delicate crust.
Ultimately, the choice between biga and poolish often comes down to personal preference and the specific characteristics you’re hoping to achieve in your homemade pizza.

If you’re after a deeply flavorful, chewy crust, biga may be the way to go. This pre-ferment is particularly well-suited for those with a bit more experience in the pizza-making realm, as it requires a bit more precision and handling.
Poolish, on the other hand, is an excellent choice for home cooks looking to experiment with Neapolitan-style pizza for the first time. Its higher hydration and more relaxed handling make it a bit more forgiving, while still delivering a delicious, airy crust.
Of course, the best way to find your perfect pizza dough is to try both biga and poolish and see which one resonates with your personal taste preferences and baking style. Embrace the journey, and let the quest for the ultimate Neapolitan-inspired pizza continue!
