- What is Biga and why do Italian pizzerias use it?
- Biga (pronounced BEE-gah) is an Italian stiff pre-ferment: flour + water (44–50% hydration) + a tiny amount of yeast (0.5–1%), fermented 16–20 hours at 16–18°C. Italian pizzamakers and bakers use Biga because it produces complex organic acids (lactic and acetic), develops deep flavour, strengthens gluten structure, and makes the final pizza more digestible than a direct-method dough.
- What is Poolish and how is it different from Biga?
- Poolish (from Polish bakers who introduced it to France) is a liquid pre-ferment with equal weights of flour and water (100% hydration) and a very small amount of yeast. It's more active than Biga and ferments in 8–16 hours at room temperature. Poolish gives a more open crumb and milder acidity than Biga. Both are called 'indirect method' (metodo indiretto) in Italian bakeries.
- What percentage of Biga should I use in pizza dough?
- Typical Biga percentages in Italian professional doughs: 30–50% for moderate flavour enhancement, 50–80% for pronounced flavour and extended shelf life, above 80% (called 'Biga al 100%') for extreme flavour complexity used in artisan bread. For home pizza, 40–60% Biga is a good starting point. The calculator lets you set any percentage from 10% to 100%.
- How do I incorporate Biga or Poolish into the final dough?
- Break the matured Biga into small pieces (it should look slightly dry and have a clean fermented aroma) and add it to the remaining flour and water. Start the mixer at low speed, gradually adding the remaining ingredients. For Poolish (which is liquid), pour it into the remaining flour and mix from the start. Add salt only in the last few minutes of mixing.
- How does Biga affect pizza dough handling?
- Biga-enriched doughs are generally more extensible (less elastic) than direct doughs of the same age, making them easier to stretch by hand. The pre-fermentation also produces glutathione (a natural reducing agent) that relaxes gluten. Pizza Napoletana made with Biga tends to stretch more easily and develop larger, irregular cornicione bubbles.
- Can I use Biga or Poolish for all Italian pizza styles?
- Yes. Biga is widely used for Pizza Napoletana, pizza in teglia (al taglio) and pizza in pala. Poolish is popular in Roman-style doughs and bread production. High-hydration teglia doughs with 50–70% Biga and 75–80% final hydration are a classic combination in Roman pizzerie. The indirect method is considered a mark of quality in Italian pizza culture.
