Caputo "00" vs King Arthur — Which Pizza Flour Should You Buy?

Buy Caputo if you make Neapolitan pizza in a 700°F+ oven. Caputo "00" Chef's Flour (the blue bag) is what nearly every Neapolitan pizzaiolo uses, sits at ~11.5% protein, takes high hydration cleanly, and bakes into a tender, charred cornicione in 60-90 seconds.

Buy King Arthur if you bake in a home oven under 550°F. King Arthur's '00' Pizza Flour is ~12.7% protein. The extra protein produces a chewier crust that holds up better during the longer 6-8 minute bake a home oven needs — and you can find it at any U.S. grocery store for the price of a Sunday morning errand.

Both are excellent flours. The bake temperature is what should decide it, not the brand loyalty.

Caputo Chef's Flour (blue bag): ~11.5% protein. Mid-range W-strength (around W260-280 on the Italian farinographic scale), which means the dough develops a moderate gluten network — strong enough to stretch into thin Neapolitan rounds without tearing, soft enough to leoparding cleanly at high heat.

King Arthur '00' Pizza Flour: ~12.7% protein. Higher gluten development. The result is a dough with more bite and chew, which matches what you'd want for NY-style or for a home-oven bake where the longer cooking time can leave a low-protein crust feeling cardboard-dry.

For context: U.S. all-purpose runs ~10-11% protein, U.S. bread flour ~12-14%, and traditional Italian "00" sits at the lower end. Higher protein isn't "better" — it's a different feel, and it pairs with different oven temperatures.

Caputo absorbs a touch more water than King Arthur. In practice that means a recipe that runs at 65% hydration with Caputo often needs 63% with King Arthur to hit the same feel — start one or two points lower if you swap.

Caputo at high hydration (65-70%) stays extensible and easy to slap out, even after a long cold ferment. The dough feels alive in the hand: soft, pliable, almost silky. This is the texture pizzaiolos chase.

King Arthur at the same hydration is firmer and tighter — more bread-dough-like. It's easier to handle for beginners because it doesn't sag, but it takes more force to stretch and is less forgiving on a wood peel.

If this is your first time making real pizza dough, start with King Arthur at 60-62% hydration. If you've been doing this a year and want softer, more extensible dough, switch to Caputo and creep hydration up to 65%.

Our dough calculator defaults to AVPN-aligned ratios — set hydration to 65% for Caputo, 62-63% for King Arthur, and otherwise leave the math alone.

Blind taste tests don't lie about this: Caputo and King Arthur taste different.

Caputo has a distinct "Italian flour" character — slightly sweeter, faintly milky, with the wheat aroma you smell when you open a fresh bag in a pizzeria. The crust browns into a darker, more aromatic color and the leopard spots carry actual flavor.

King Arthur is cleaner and slightly nuttier. Less floral, more straightforward grain. The crust browns evenly but doesn't get the same depth of color at home-oven temperatures.

Neither is wrong. If you're chasing the Neapolitan experience — the one you remember from a wood-fired oven in Naples — Caputo gets you closer. If you're making a weeknight pizza for your family and "good dough" is the bar, King Arthur clears it just fine.

Neapolitan (broiler method, ~700°F). Caputo wins clearly. The lower protein + higher absorption combination is what the style was designed around. King Arthur works, but you'll get a chewier, less puffy cornicione. Try our Classic Margherita recipe with Caputo at 65% hydration.

New York (baking steel, ~550°F, 6-8 min bake). King Arthur is the better match. The extra protein survives the longer bake and produces the foldable, chewy slice you want. Caputo can work but tends to bake into something more cracker-like at that lower temperature. See NY Cheese Slice.

Detroit (pan, 500°F). King Arthur. Detroit needs structure to hold up the heavy toppings, and the higher protein delivers. Caputo here is a waste — the style doesn't ask for the soft Neapolitan texture.

Sourdough pizza. Either works; high-hydration sourdough has historically preferred a stronger flour, so King Arthur is the safer call unless you're already comfortable with Caputo at 70%+ hydration.

Caputo Chef's Flour (2.2 lb bag): ~$12-18 on Amazon, ~$10-14 at Italian grocers and well-stocked supermarkets. Hard to find at standard grocery chains in the U.S.

King Arthur '00' Pizza Flour (3 lb bag): ~$8-10 at any U.S. grocery store, often on the same shelf as their bread flour. The most accessible high-quality pizza flour in the country.

If you make pizza twice a month or more, buy a 2.2 lb bag of Caputo and a bag of King Arthur and run both — you'll learn more from one side-by-side bake than from ten blog posts.

Buy Caputo if you have a baking steel + broiler setup (or an outdoor pizza oven), you make Neapolitan style, and you care about the texture and aroma signatures the style is known for.

Buy King Arthur if you're new to pizza, you bake in a standard home oven below 550°F, you make NY or Detroit style, or you want to walk into any supermarket and pick up flour without planning.

Buy both if you cook pizza weekly and want to understand what your flour is actually doing to your dough. It's the cheapest education in pizza you can buy.

This isn't a brand allegiance question. It's a temperature-and-style question. Match the flour to the bake and either one will make better pizza than whichever you have right now.
