A poolish is a highly hydrated preferment made from equal parts flour and water with a small amount of commercial yeast. After fermenting for several hours or overnight, it develops organic acids and aromatic compounds that improve the dough's flavor, fermentation, extensibility, and crust color. The result is pizza dough that is easier to stretch, bakes with better oven spring, and produces a lighter, more open crumb.
Rather than estimating ingredient amounts, professional pizza makers calculate the poolish as a percentage of the recipe's total flour. This ensures the final dough maintains the intended hydration, salt level, and dough weight while delivering consistent results from one batch to the next.
A poolish (pronounced pwah-lish) is a liquid preferment made with equal parts flour and water (100% hydration) and a small amount of commercial yeast. After fermenting for 12–16 hours, it becomes active and develops the flavor, aroma, and fermentation strength needed for high-quality pizza dough.
Incorporating a poolish into the final dough improves flavor, gluten development, and dough extensibility, making it easier to stretch into a pizza base. It also promotes better oven spring, a lighter open crumb, and a crisp, well-browned crust. For these reasons, poolish is widely used in artisan pizza and bread baking.
The benefits of using a poolish extend beyond flavor alone. A well-fermented poolish improves every stage of the dough—from mixing and shaping to baking—resulting in a pizza that is easier to work with and produces a superior crust.
Slow fermentation develops organic acids and aromatic compounds that give pizza dough a deeper, more balanced flavor than a typical same-day dough.
A mature poolish improves dough extensibility, making it easier to stretch into thin, even pizza bases with less tearing and shrinkage.
Improved fermentation helps retain more gas during baking, producing a crust with better oven spring, a more open crumb, and crisp edges.
Poolish pizza dough is prepared in two stages: the poolish, which ferments for 12–16 hours, and the final dough, mixed the following day. Every ingredient is calculated from the recipe's total flour weight, ensuring consistent hydration, dough yield, and flavor at any batch size.
This calculator handles the entire poolish pizza dough workflow — from overnight preferment to final dough — with precise baker's percentage math.
Enter the number of dough balls and their desired weight. The calculator multiplies these to determine your total dough weight target.
Set hydration (total), salt, oil, poolish percentage (how much flour goes into the poolish), and poolish hydration (typically 100%).
Using reverse baker's percentage: Total Flour = Dough Weight ÷ (1 + Hydration + Salt% + Oil%). Total water is flour × hydration.
The poolish gets the specified percentage of the total flour and matching water at its hydration level. Everything else goes into the final dough.
Results show the poolish ingredients (make the night before) and the final dough ingredients (add the next day), with all weights in your chosen unit.
The timing of your poolish affects both flavor and convenience. Here are the two most common approaches for home bakers and pizzerias.

A poolish improves pizza dough in three ways: (1) Flavor — long fermentation develops complex, wheaty, slightly nutty flavors. (2) Texture — the gluten becomes more extensible, so the dough stretches easily without tearing. (3) Crust — more gas retention during baking creates a lighter, airier crust with a crisp exterior and open, airy interior.
No — the key difference is the pre-fermentation. Regular pizza dough (direct method) mixes all ingredients at once and proofs for 1–4 hours. Poolish pizza dough uses a preferment that ferments for 12–16 hours before the final dough is mixed. This extra time creates better flavor and texture but adds a day of planning to your baking schedule.
No — they are both preferments but differ in consistency. A poolish is wet (100% hydration, equal parts flour and water) and fermented at room temperature for 12–16 hours. A biga is stiff (50–60% hydration) and typically fermented for 16–24 hours. Poolish produces a softer, more extensible dough; biga gives a stronger, more structured dough with a slightly different flavor profile. For Neapolitan pizza, poolish is more common.
The sweet spot for most pizza doughs is 30–50% of the total flour in the poolish. A 40% poolish is the most common, giving a good balance of flavor development and convenience. Lower percentages (20–30%) still improve flavor but require a higher yeast percentage to build enough fermentation activity. Higher percentages (50–60%) produce a more intensely flavored dough but require careful timing to avoid over-fermentation.
Yes — but it is technically a sourdough poolish and behaves differently. A sourdough poolish ferments slower and produces more acidic, tangy flavors. The timeline changes from 12–16 hours to 16–24 hours, depending on starter strength and temperature. You would also need to account for the flour and water in the starter when calculating percentages. This calculator assumes commercial yeast for the poolish — see our Sourdough Pizza Dough Calculator for sourdough options.
A ready poolish has three signs: (1) The surface is covered with bubbles, some bursting. (2) The texture is webbed and lacy with a network of gluten strands underneath. (3) It has a pleasant, slightly yeasty smell (not sour or acidic). The volume should have increased significantly — at least doubled. A poolish that is over-fermented will smell strongly of alcohol and have a thin, watery consistency — discard it and start again.
A poolish is a simple preferment that can significantly improve the flavor, fermentation, and handling of pizza dough. By fermenting a portion of the flour before the final mix, it develops a more complex aroma, improves dough extensibility, and helps produce a lighter, well-browned crust.
Using the correct ingredient ratios is just as important as the fermentation itself. This Poolish Pizza Dough Calculator calculates the exact flour, water, yeast, salt, oil, and poolish required for your recipe, making it easy to scale batches while maintaining consistent hydration and baker's percentages.
