Biga in Pizza Dough: Fermentation, Structure and Professional Use

Biga in Pizza Dough: Fermentation, Structure and Professional Use

Biga is one of the most widely used Italian preferments in professional pizza making.

When managed correctly, it can improve dough structure, aroma, extensibility and fermentation performance.

Unlike a liquid preferment such as poolish, biga is prepared with relatively low hydration. This creates a firm and irregular dough that ferments slowly before being incorporated into the final dough.

For a deeper understanding of preferments, fermentation and professional dough production, visit the Professional Pizza Technical Manual.

WHAT IS BIGA ?


Traditional biga is made with three basic ingredients:

Flour • Water • Yeast

Hydration is generally around 44–50%, although the exact percentage depends on the flour, fermentation time, temperature and production method.

Only a small quantity of yeast is normally required because biga is fermented for many hours.

The purpose of the preferment is not simply to make the dough rise.

It creates controlled fermentation and enzymatic activity before the final mixing stage.

WHY USE BIGA IN PIZZA DOUGH ?

When correctly managed, biga can contribute to:


• More complex aroma and flavour
• Improved dough structure
• Better gas retention
• Good extensibility
• A lighter internal crumb
• More pronounced fermentation characteristics
• Improved baking performance


These benefits depend on correct management of temperature, hydration and fermentation.

Biga is not automatically better than direct dough. It is simply a different fermentation method that gives the pizza maker greater control over the final dough.

HYDRATION AND MIXING


Biga should not be mixed like a finished pizza dough.

The purpose of the first mixing stage is to distribute the water and yeast through the flour without fully developing the gluten.

Start by dispersing the yeast in the measured water.

Add the water gradually to the flour while mixing at low speed.

Mix only until the flour has absorbed the water sufficiently and the characteristic fragmented structure begins to form.

The finished biga should be:


• Firm
• Coarse
• Irregular
• Fragmented
• Relatively dry


It should not become a smooth or elastic dough ball.

There should be no large quantities of completely dry flour, but the gluten should remain only partially developed.

With a spiral mixer, use low speed and stop mixing once the mixture forms irregular pieces of dough.

The exact mixing time depends on the mixer, batch size, flour and hydration.

For this reason, visual and physical assessment is more important than following a fixed number of minutes.

Overmixing should be avoided.

If the biga becomes smooth, elastic and strongly developed, too much gluten development has already taken place.

Undermixing should also be avoided because large areas of dry flour indicate poor water distribution.

The correct result is:

Hydrated enough to ferment evenly, but mixed only enough to remain coarse, firm and irregular.

FERMENTATION TEMPERATURE


Temperature is one of the most important variables when working with biga.

If the temperature is too high, fermentation can progress too quickly.

If it is too low, fermentation may develop too slowly.

The pizza maker must consider:

Flour temperature + Water temperature + Room temperature + Fermentation time

These factors work together and determine the final condition of the biga.

The objective is controlled fermentation, not maximum fermentation.


HOW LONG SHOULD BIGA FERMENT ?


There is no single fermentation time suitable for every biga.

The correct duration depends on:


• Yeast quantity
• Flour strength
• Hydration
• Ambient temperature
• Refrigeration
• Percentage of biga used


A commonly used professional method is approximately 16–20 hours of fermentation.

However, this should not be treated as a fixed rule.

The condition of the preferment is more important than the number of hours alone.

RECOGNISING A PROPERLY FERMENTED BIGA

A mature biga should develop a clear fermented aroma and an open internal structure while maintaining its characteristic firmness.

It should not become excessively wet, collapsed or strongly acidic.

An over-fermented biga can weaken the final dough.

An under-fermented biga may not provide the expected aromatic and structural benefits.

PERCENTAGE OF BIGA IN THE FINAL DOUGH

Biga can represent different percentages of the total flour.

For example:


30% Biga
50% Biga
70% Biga
100% Biga


Increasing the percentage changes the behaviour of the dough and requires adjustments to hydration, mixing, fermentation and temperature management.

To calculate flour, water, hydration, salt, yeast and dough quantities accurately, use the Vincicoppolas Dough Calculator.

FINAL DOUGH MIXING


During the final mixing stage, the mature biga is combined with the remaining ingredients to create the finished dough.

Unlike the first mixing stage, the objective now is to develop the required gluten structure.

Break the mature biga into smaller pieces to help it incorporate evenly.

Add the remaining water progressively, especially when working with higher final hydration.

The final hydration must always be calculated using the total flour and total water in the complete recipe, including the flour and water already contained in the biga.

You can calculate these quantities with the Vincicoppolas Dough Calculator.


BIGA AND FLOUR STRENGTH

Flour selection is particularly important when using long preferments.

The flour must have sufficient strength and stability to tolerate the planned fermentation without excessive gluten degradation.

Fermentation time, temperature and hydration all influence dough strength.

Flour should therefore be selected according to the complete production process rather than protein percentage alone.

For more detailed information about flour strength, fermentation, hydration, biga, poolish and professional dough management, visit the Professional Pizza Technical Manual.


BIGA VS DIRECT DOUGH

A direct dough can produce excellent pizza and is often easier to control.

Biga introduces an additional fermentation stage and therefore more variables.

Its advantage is greater control over flavour, structure and fermentation characteristics.

However, mistakes during the preferment stage can affect the entire final dough.

Professional consistency comes from understanding and controlling these variables rather than following a formula mechanically.

FINAL CONSIDERATIONS

Biga is a powerful professional technique, but its effectiveness depends on control.

Flour strength, hydration, yeast, temperature and fermentation time must work together.

Once these variables are understood, biga becomes more than a recipe.

It becomes a fermentation system that allows the pizza maker to design dough with specific structural, aromatic and baking characteristics.
