Best flour for pizza: 00, bread flour or high-gluten?
The best flour for pizza is the one whose strength matches how long your dough ferments. Same-day dough: about 11% protein (Italian W 180–220). 24–48 hours in the cooler: bread flour around 12.5–13% (W 250–290). 72 hours or more: high-gluten, 13.5–14% (W 300–380). “00” tells you how finely milled and white the flour is, not how strong. American bread flour works well for 24–48 h doughs in a deck oven.
“00”, bread or high-gluten: what the bag actually tells you
Italian, French and German flours carry a type number based on ash (the mineral content left after milling). In Italy that’s 00, 0, 1, 2 and integrale; 00 means at most 0.55% ash and at least 9% protein, nothing more. American flour has no type numbers: you buy all-purpose, bread flour, high-gluten or whole wheat, sorted roughly by protein — and the mill prints the protein on the spec sheet.
Strength is a different measure. Italian mills quote W, from the Chopin alveograph: the energy needed to blow a sheet of dough into a bubble until it bursts. High W means gluten that holds up through a long, cold fermentation. Protein percentage is a rough proxy. A “00” can be a weak cake flour at W 150 or a long-ferment flour at W 350.
| US label | Typical protein | Rough Italian equivalent | Pizza use |
|---|---|---|---|
| All-purpose | 10–12% | 00 at W 180–220 | Same-day dough; weak for long ferments |
| Bread flour | 12–13% | 00/0 at W 260–300 | 24–48 h dough, deck ovens |
| High-gluten (the classic NY slice flour) | 13.5–14.5% | Manitoba, W 350+ | 48–72 h+ NY-style, pan pizza, biga |
| “00” pizza flour (Caputo, Polselli…) | 11.5–13% | As labeled, W 220–330 | Neapolitan, high-heat ovens |
Typical values. King Arthur’s professional line, for example, lists Sir Galahad all-purpose at 11.7% and Sir Lancelot high-gluten at 14%. Ask for the spec sheet of the lot you buy.
Which strength for which fermentation time?
| Fermentation | W | Protein | Hydration | Examples |
|---|---|---|---|---|
| Same day, 6–8 h | 180–220 | 10.5–11.5% | 55–58% | All-purpose, Pivetti Margherita |
| 24–48 h cold | 250–290 | 12–12.5% | 57–60% | Caputo Pizzeria (W 260–280), many bread flours |
| 48–72 h | 270–330 | 12.5–13% | 58–62% | Caputo Nuvola (W 270–290), strong bread flour |
| 72 h+ | 330–380 | 13–14%+ | 60–64% | High-gluten, Pivetti Girasole |

Italian mills that grade flours by days give a handy rule: a “2-day” flour around 57% water, a “3-day” flour around 58%, a “4-day-plus” flour around 59%. High-gluten flour on a same-day dough makes a tough, rubbery crust; it needs time and water. Stronger flour drinks more water, so settle the flour first and the hydration second.
How much water your flour can take
Does “00” brown in a deck oven?
Most American pizzerias bake in gas deck or conveyor ovens at roughly 500–650 °F, where a pie spends several minutes. Unmalted “00”, designed for 60–90 seconds at 850 °F, browns poorly there and dries out. Most American bread and high-gluten flours are malted (check the ingredient list for malted barley flour), which is exactly why they color well in a deck. If you run an unmalted flour, a small dose of diastatic (not roasted) malt powder fixes it — follow the supplier’s rate, usually well under 1% of the flour. More than that makes a sticky dough and a dark, sweet crust.
A practical blend for a deck oven and 48-hour dough: 70% Italian “00” at W 260–300, 30% American bread flour. You get the extensibility of the “00” and the color of the malted flour.
Enriched or not: read the ingredient list
Most American white flour is sold enriched. Under the federal standard for enriched flour, that means added niacin, iron, thiamin, riboflavin and folic acid. It does not change how dough behaves. It does change your ingredient list: “enriched wheat flour (wheat flour, malted barley flour, niacin, iron, thiamin mononitrate, riboflavin, folic acid)” on a domestic bag, against just “wheat flour” on most imported Italian “00”. If you publish ingredients online or sell anything packaged, update them when you switch.
Pizza premixes and dough conditioners: convenience vs control
Some pizza flour blends add malt, dough conditioners, extra vital wheat gluten, enzymes or emulsifiers. They forgive a lot and hold well in the cooler. The trade-off is a longer ingredient list for your allergen records, dependence on one supplier and poor results with poolish or biga. Plain flour gives you control.

How to switch flour without wrecking a weekend
- Make a 10 lb test batch on a slow day. Change only the flour; keep yeast and salt.
- Adjust water by 2 points at most, adding the last of it late in the mix.
- Check final dough temperature (73–77 °F) and your cooler with a probe.
- Bake at your real service temperature, with the oven loaded.
- Hold a month of stock if the importer has long lead times.

Cost per pizza, bags and storage
Do the math from your own invoice. A 9 oz dough ball at 60% hydration holds about 5½ oz of flour, a little over a third of a pound. Divide the price of a 50-pound bag by 50 to get your price per pound: at $30 a bag that is about 20 cents of flour per pie, and even an imported “00” at twice the price adds cents — less than an extra quarter-ounce of mozzarella. Store bags off the floor on pallets or dunnage racks, dry, below about 70 °F, first in first out.
“48-hour dough, Italian flour” is a selling point nobody sees on a delivery app listing. On your own site, you can say it and keep the margin.
Where American pizzerias buy flour
- Broadline distributors: Sysco, US Foods and regional houses carry bread and high-gluten flours from the big mills, plus some Italian “00”.
- Cash-and-carry and warehouse clubs: Restaurant Depot, Costco Business Center and Sam’s Club stock 50-pound bags.
- Italian importers and specialty distributors: full ranges (Caputo, Polselli, 5 Stagioni) and spec sheets on request.
- Mills directly: King Arthur, Ardent Mills, General Mills and regional mills sell professional lines with published specs.
FAQ
Is “00” flour always best for pizza?
No. “00” means fine milling and low ash. It can be weak or strong. Match protein (or W) to your fermentation time; around 12.5–13% protein suits most 24–72 h pizzeria doughs.
Can I use bread flour for pizza?
Yes. At 12–13% protein it suits 24–48 h dough and browns well in deck ovens because it is usually malted. It’s less extensible than “00”, so balls take longer to open. Blending with “00” fixes that.
What is high-gluten flour for?
Long cold ferments and the chewy, foldable New York–style slice. At 13.5–14% protein it needs 48 hours or more and 62–65% water; on a same-day dough it is tough.
What does W mean on Italian flour?
W is the alveograph strength: how much energy it takes to stretch dough to bursting. Below 200 is weak, 250–300 medium-strong, above 330 very strong.
