Dough

Bulk fermentation, balling and final proof for pizza

After kneading, dough goes through three stages: bulk fermentation, a rest in one mass that builds structure and flavour; balling, which shapes the dough balls; and the final proof, which makes them extensible and fills them with gas. Before any fridge rest I always start fermentation with 30 minutes to 1 hour at room temperature, and I let direct-dough balls warm above 17–18 °C (63–64 °F) before stretching.

Three rests, three goals

Once the dough is kneaded, most of the work happens while it rests. I split that time into three stages, each with its own purpose:

StageWhat happensMain goal
Bulk fermentationThe dough rests in one massStructure (strength) and flavour
BallingThe dough is divided and shaped into ballsSurface tension and the right weight for the pizza
Final proofThe dough balls rest until bakingExtensibility for stretching, gas for the cornicione

These three stages are also your main levers for balancing gluten strength and extensibility.

Bulk fermentation

What it does

During bulk fermentation the gluten network recovers from kneading, and fermentation and maturation get under way. It has two goals:

  • build structure: bulk fermentation acts directly on the dough’s strength, and you adjust it to the product;
  • develop flavour: a dough that has had a proper bulk simply tastes better, thanks to fermentation and maturation.

For Neapolitan pizza, the aim during bulk is a medium level of fermentation that gives a balanced structure. Some biga protocols, on the other hand, skip bulk fermentation entirely to avoid adding strength.

The container

I bulk the dough in an airtight, lightly oiled container, ideally transparent so I can follow fermentation and the rise in volume. A fairly narrow, tall container encourages the dough to rise upwards.

Room temperature or fridge

Bulk fermentation can happen at room temperature or at a controlled temperature (the fridge). Orders of magnitude from my direct protocols:

ApproachGuide
Traditional Neapolitan30–60 min on the bench at 20–24 °C (68–75 °F), then balling
Bulk entirely at room temperature3–5 h at 20–25 °C (68–77 °F)
Room temperature, then fridge2–4 h at 20–24 °C, then 8–10 h at 5–7 °C (41–45 °F)
Fridge bulk30 min–1 h at 20–24 °C, then about 24 h at 5–7 °C

How long that pause lasts depends on the dough temperature at the end of kneading and on the room: count 30 minutes to 1 hour, longer if your kitchen is cool. In the fridge I aim for 6–8 °C (43–46 °F): above 4 °C (39 °F) fermentation and maturation carry on slowly; below it they almost stop and the dough no longer works.

Balling

Balling means shaping the dough balls. Two parameters matter.

Surface tension

The more tension you put on the surface of the dough ball, the more elasticity you give it. It is a very useful fine-tuning tool: if bulk fermentation did not give the dough enough strength, tighter balling makes up for it. Once shaped, the dough balls are sealed underneath and stored in an airtight tray.

Dough ball weight

Matching pizza size and dough ball weight optimises baking and keeps the pizza light.

StyleDiameterDough ball weight
Traditional Neapolitan30–33 cm (12–13 in)200–220 g (7–7.8 oz)
Contemporary Neapolitan, direct28–33 cm (11–13 in)240–265 g (8.5–9.3 oz)
Contemporary with biga30 cm (12 in)250–255 g (8.8–9 oz)
Contemporary with biga33 cm (13 in)260–265 g (9.2–9.3 oz)

The dough ball weight calculator does the matching for you.

Final proof

What it does

The final proof is the last rest before baking. It lets the dough balls:

  1. reach the extensibility needed for stretching;
  2. build up the gas that gives an airy pizza.

A long final proof favours extensibility. In the fridge, it suits very extensible products like Neapolitan pizza; at room temperature, it suits stronger products and indirect doughs better.

Room temperature or fridge

ApproachGuide
Direct dough, fridge proof30 min–1 h at room temperature, then about 24 h at 5–8 °C (41–46 °F)
Traditional Neapolitan, fridgeAbout 24 h at 5–6 °C (41–43 °F)
Biga dough, room temperature4–5 h at 22–24 °C (72–75 °F), the last 2–3 h in the fridge
Biga dough, fridgeUp to 24 h at 6–8 °C (43–46 °F)
Indirect doughs in general, room temperatureDough balls usable after 3–4 h at 22–25 °C (72–77 °F)

The same rule as for bulk applies: a room-temperature pause before the fridge to get the dough balls fermenting. The dough schedule planner helps you fit these times around mealtime.

Bringing dough balls back to temperature

A dough ball straight from the fridge is cold, which makes it strong and hard to open. For a direct dough, I let it warm up at room temperature and finish rising before stretching: 30 minutes to 2 hours for a traditional dough, at least 2 hours for a contemporary one, depending on the room and how far fermentation has gone. The ideal is a dough ball above 17–18 °C (63–64 °F); you can start from 16–17 °C (61–63 °F). In a very warm kitchen a slightly colder ball is fine, because it warms up a lot while you stretch it.

Biga dough balls are the exception: they can be stretched straight from the fridge. And if their final proof was at room temperature, I give them a few hours in the fridge before stretching.

A thermometer is your best friend here: the role of each temperature is explained in why temperature drives dough.

Frequently asked questions

What is the difference between bulk fermentation and final proof?

Bulk fermentation is the rest of the dough in a single mass right after kneading: it builds structure and flavour. The final proof is the last rest, once the dough balls are shaped: it gives them the extensibility needed for stretching and builds up the gas that will puff up the cornicione.

Can I put the dough straight into the fridge after kneading?

I don’t recommend it. Dough that goes into the fridge too early may never get its fermentation going. Leave it 30 minutes to 1 hour at room temperature first, more or less depending on how warm the room and the dough are.

How heavy should a Neapolitan dough ball be?

For a 30–33 cm (12–13 in) traditional Neapolitan, 200 to 220 g. For a contemporary one, 240 to 265 g for 28–33 cm (11–13 in); with a biga, 250–255 g for 30 cm and 260–265 g for 33 cm. The bigger the pizza, the heavier the ball.

How long should dough balls sit out of the fridge before stretching?

30 minutes to 2 hours for a traditional dough, at least 2 hours for a contemporary one, depending on room temperature and how far fermentation has gone. I aim for a dough ball above 17–18 °C (63–64 °F). Biga dough balls, on the other hand, can be stretched straight from the fridge.
