What Does “00 Flour” Actually Mean?
Tipo 00 is one of the most recognised terms in pizza making. But the number printed on the flour bag tells us much less about actual dough performance than many people assume.
Mention Italian pizza and someone will eventually say, “You need 00 flour.”
Tipo 00 is certainly important in Italian pizza making, particularly Pizza Napoletana. But 00 is a flour classification. It is not a guarantee that a flour will suit every hydration, fermentation system or pizza style.
What does 00 actually tell us?
Italian flour classifications such as 00, 0, 1 and 2 relate primarily to the degree of refinement and mineral or ash content of the flour.
A common explanation is that 00 simply means extremely finely ground flour. That is incomplete. The classification itself does not tell us everything about flour strength, absorption, extensibility or fermentation tolerance.
Look beyond the number
When I select flour for a professional pizza operation, I look beyond the 00 classification.
Flour strength, protein behaviour, W value, P/L, absorption, extensibility and stability all help us understand how that flour may behave within a dough system.
Hydration must suit the flour
Seventy percent hydration with one flour can behave very differently from seventy percent hydration with another. Higher hydration is not automatically better pizza.
The appropriate hydration depends on the flour, pizza style, fermentation system, equipment and the people who need to reproduce the dough every day.
Climate changes the system
This becomes especially important in warmer markets. A dough system that behaves comfortably in Europe may require adjustment in Delhi, Dubai, Jakarta or Kuala Lumpur.
Water temperature, flour temperature, mixer friction, refrigeration and ambient kitchen temperature all influence final dough temperature and therefore fermentation.
Simply importing an Italian flour and copying a recipe does not automatically reproduce the same pizza in another kitchen.
Different pizzas need different flour strategies
Pizza Napoletana, New York Style, Pizza e Pala, Detroit Style, Pizza al Taglio, Sicilian, Grandma Style and Thin & Crispy pizza do not place identical demands on a dough.
Even delivery changes the equation because the pizza must maintain structure and eating quality after leaving the oven.
The best flour is not simply the flour marked “00”.
It is the flour whose characteristics match the pizza style, hydration, fermentation, climate, production environment and commercial requirement.
