Flour Types & W-Value: The Complete Pizza Flour Guide

Tipo 00, Tipo 0, German Type 405, US bread flour — what actually matters for pizza is grind, ash content, protein and the W-value. Here is the no-nonsense guide.

Quick Answer

What is the difference between Tipo 00 and Tipo 0?

Tipo 00 is more finely milled and has a lower ash content (max 0.55%) than Tipo 0 (max 0.65%). Tipo 00 feels powder-fine; Tipo 0 is slightly coarser. The grade says nothing about protein or strength — a Tipo 00 cake flour and a Tipo 00 pizza flour are completely different products. Always check the W-value and protein percentage on the side label.

Why Flour Confuses Everyone (and Why It Shouldn't)

Walk into any supermarket in Italy, Germany and the US and you will find three completely different flour systems on the shelf. None of them measure the same thing. "Tipo 00" tells you about grind. "Type 405" tells you about ash. "Bread flour" tells you about protein. Pick the wrong one for your pizza and the dough will fight you for hours.

This guide cuts through the noise: what each label actually means, what the W-value is, and how to translate between the three systems so you can buy the right bag — wherever you are.

Italian Flour: Tipo 00, 0, 1, 2 and Integrale

Italian flour grades describe how finely the wheat is milled and how much of the bran was sifted out. They say nothing about protein.

TypeTextureAsh (max)Typical use
Tipo 00Powder-fine, almost talc0.55%Neapolitan pizza, fresh pasta, cakes
Tipo 0Fine, slightly coarser0.65%Pizza in teglia, bread, longer ferments
Tipo 1Visible specks of bran0.80%Rustic pizza, sourdough, pinsa
Tipo 2Coarse, semi-wholegrain0.95%Country bread, high-flavor pizza
IntegraleWholegrainup to ~1.7%Wholewheat bread, blends
Ash content is the mineral residue left after burning a flour sample. The lower the number, the whiter and more refined the flour.

So Tipo 00 is "The Best"?

No. Tipo 00 is just the finest grind. A Tipo 00 cake flour and a Tipo 00 pizza flour share the grade but behave nothing alike — because the protein and the W-value are different. Always read the second label on the bag: the technical data.

The W-Value: Flour's Real Strength Rating

The W-value (sometimes "W index" or "alveographic strength") is the single most useful number on a bag of Italian pizza flour. It measures how much work is needed to inflate a thin sheet of dough until it bursts, using a Chopin alveograph.

Simply put: higher W = stronger gluten = longer fermentation possible.

W-valueStrengthBest forMax ferment
W 90–160Weak (deboli)Cakes, biscuits, short doughsup to 4 h
W 160–250MediumSame-day pizza, focaccia, ciabatta4–12 h
W 250–310Strong (forti)24–48 h pizza, classic Neapolitan12–48 h
W 310–370Very strong48–72 h cold ferment, panettone, biga48–72 h+
W 370+Special / "Manitoba"Blends, very long ferments, brioche72 h+
### How the W-Value Is Measured

The Chopin alveograph test is brutally physical:

  • A standard dough is mixed from the flour with a fixed amount of salted water.
  • A small disc is cut and rested.
  • Air is blown into the disc until it inflates into a bubble and bursts.
  • A pressure curve is recorded. The area under that curve is the W-value, expressed in 10⁻⁴ joules.
  • Two other numbers come from the same test and matter for pizza:

    • P — tenacity (resistance to stretching)
    • L — extensibility (how far the dough stretches before tearing)
    • P/L ratio — balance between the two. 0.45–0.60 is the sweet spot for pizza. Above 0.7 the dough snaps back; below 0.4 it tears.

    W-Value vs. Protein: They Are Not the Same

    Protein percentage tells you how much gluten-forming protein is in the flour. The W-value tells you how good that protein is at building a strong, elastic network.

    Two flours can both have 13% protein but very different W-values, depending on the wheat variety and how it was grown. For pizza, W is the more honest number — but you will mostly see it on Italian bags. Outside Italy, protein percentage is your best proxy.

    Fermentation Time × W-Value: The Cheat Sheet

    Match your flour to your schedule, not the other way around.

    Your planTarget WTarget protein
    Same-day, 4–8 h at room temp220–26011–12%
    24 h (mostly cold)260–30012–13%
    48 h cold ferment300–34013–14%
    72 h cold ferment or biga/poolish340+14%+
    Rule of thumb: weak flour + long ferment = a slack, sticky, blown-out dough. Strong flour + short ferment = a tight, rubbery crust that never relaxes.

    German vs. Italian vs. American Soft Wheat Flour

    All three countries grade flour differently. Here is a practical translation table for soft wheat (Triticum aestivum) — the wheat used for pizza, bread and pastry.

    ### The Trap Most People Fall Into Tipo 00 ≠ Type 405. They look similar (both pale, both fine), but:
    • Italian Tipo 00 pizza flour is milled from strong wheat with 12–13% protein and a W of 260–340.
    • German Type 405 is milled from soft wheat with ~9.5% protein and almost no strength. It is for cakes.

    Using Type 405 for Neapolitan pizza is the single most common reason German home bakers complain about "torn, leathery dough."

    What to Buy Outside Italy

    • Germany: Look for Type 550 (same-day) or Type 812 (24–48 h). For genuine Neapolitan, buy imported Caputo Pizzeria, Cuoco or 5 Stagioni Pizza Napoletana.
    • USA: Bread flour (~12–13% protein) covers most pizza styles. King Arthur Bread Flour or Central Milling Type 00 are reliable. For Neapolitan, again, imported Italian Tipo 00 is the gold standard.
    • UK: Strong white bread flour = roughly Italian Tipo 0. For 00, buy imported.

    How to Read an Italian Flour Bag in 30 Seconds

    The front says "Farina di grano tenero Tipo 00." That is just the grade. Flip to the side panel and look for:

  • W (e.g. W 300) — strength
  • P/L (e.g. 0.55) — balance
  • Proteine (e.g. 13.5 g per 100 g) — protein content
  • Maturazione consigliata — recommended maturation time
  • If those four numbers match your plan, you bought the right bag.

    Quick-Pick Recommendations by Style

    • Neapolitan, 24 h: Tipo 00, W 260–300, 12.5–13% protein. Caputo Pizzeria is the classic.
    • Neapolitan, 48–72 h cold: Tipo 00, W 320–360. Caputo Cuoco, 5 Stagioni Manitoba blend.
    • Roman al taglio (high hydration): Tipo 0 or Tipo 1, W 300–340.
    • NY style: US bread flour, 12.5–13.5% protein.
    • Pinsa Romana: Blend of Tipo 0, rice flour and soy — or pre-mixed Pinsa flour.
    • Sourdough pizza: Tipo 1 or a 70/30 blend of Tipo 00 + Tipo 1 for flavor.

    The honest truth: there is no single "best pizza flour." There is the right flour for your fermentation schedule and your style — and now you know how to find it.

    FAQ

    What is the difference between Tipo 00 and Tipo 0?

    Tipo 00 is more finely milled and has a lower ash content (max 0.55%) than Tipo 0 (max 0.65%). Tipo 00 feels powder-fine; Tipo 0 is slightly coarser. The grade says nothing about protein or strength — a Tipo 00 cake flour and a Tipo 00 pizza flour are completely different products. Always check the W-value and protein percentage on the side label.

    What does the W-value on Italian flour mean?

    The W-value measures how much work is needed to inflate a sheet of dough until it bursts, using a Chopin alveograph. Higher W = stronger gluten = longer fermentation possible. For 24-hour pizza, target W 260–300. For 48–72 hour cold ferments, target W 300–360. Below W 220 the flour is too weak for long pizza fermentations.

    Can I use German Type 405 for Neapolitan pizza?

    No. Type 405 is a German cake flour with ~9.5% protein and very weak gluten — despite looking similar to Italian Tipo 00. For pizza, use German Type 550 (same-day) or Type 812 (24–48 h), or buy imported Italian Tipo 00 pizza flour like Caputo Pizzeria or 5 Stagioni.

    What is the American equivalent of Italian Tipo 00 pizza flour?

    There is no exact equivalent. American bread flour (~12–13% protein) is the closest match for most pizza styles and works well for New York style. For authentic Neapolitan pizza, you need genuine Italian Tipo 00 with W 260–340 — brands like Caputo or 5 Stagioni are widely imported in the US.

    Is W-value the same as protein percentage?

    No. Protein percentage tells you how much gluten-forming protein is in the flour. W-value tells you how strong and elastic that gluten network can become. Two flours with the same 13% protein can have very different W-values depending on wheat variety and growing conditions. For pizza, W is the more reliable number when available.

    Which flour should I use for a 48-hour cold ferment?

    Choose a strong flour with W 300–340 and 13–14% protein. In Italy: Tipo 00 marked Cuoco or similar high-strength labels. In Germany: Type 812 or imported Italian flour. In the US: bread flour with 13%+ protein, or imported Caputo Cuoco. Weak flour will collapse over 48 hours and produce a slack, sticky dough.

    What does the P/L ratio mean on a flour bag?

    P is tenacity (how much the dough resists stretching), L is extensibility (how far it stretches before tearing). The P/L ratio balances the two. For pizza, the sweet spot is 0.45–0.60. Above 0.7, the dough snaps back and is hard to shape. Below 0.4, it tears easily during stretching.
