Bakery Flour Guide: 00 vs Bread vs Pastry Flour (and When to Buy in Bulk)

Flour is the one ingredient every bakery, pizzeria and pastry shop buys every week, and choosing the wrong type shows up immediately in the crumb, the crust and the cost. This guide compares the main flour types, what each one is for, and how to buy flour in bulk without waste.

The short answer

• Bread, bagels, rolls: high-protein bread flour.
• Neapolitan pizza, fresh pasta: Italian 00 flour.
• Cakes, muffins, cookies: lower-protein pastry or cake flour, or all-purpose.
• Everything in between: all-purpose flour.

Why protein content matters

Protein in flour forms gluten when it is mixed with water. More gluten means a stronger, chewier dough that holds gas well, which is what you want in bread. Less gluten gives a tender, soft crumb, which is what you want in cakes and pastries. As a rough guide, bread flours sit around 12–14% protein, all-purpose around 10–12%, and pastry and cake flours below 10%. Always check the specification on the bag, because brands and mills differ.

00 flour: what it is and who needs it

“00” is an Italian grading that describes how finely the flour is milled, not how strong it is. 00 flours are very fine and give a smooth, extensible dough. Pizza-specific 00 flours are milled from wheat suited to long fermentation and very hot ovens, while some 00 flours are made for fresh pasta or general baking.

At Beta Shop you will find Mulino Caputo 00 Pizzeria and 00 Chef’s flour in 1 kg bags and cases, Caputo Napoletana pizza flour in 25 kg sacks, and 5 Stagione 00 Napoletana, Manitoba-style 00 and fresh pasta flour in 10–25 kg bags.

Bread flour

Choose a high-protein bread flour for pan breads, artisan loaves, bagels and enriched doughs that need structure. Stronger flour also tolerates longer mixing and fermentation.

All-purpose flour

A medium-protein flour that covers most everyday baking. Canadian all-purpose flour is typically milled from hard wheat and is a little stronger than many all-purpose flours elsewhere, so it works well for both breads and quick breads.

Pastry and cake flour

Low-protein flours give tender cakes, delicate pastries and soft cookies. If a recipe calls for cake flour and you only stock all-purpose, test before switching, as the texture will change.

Specialty flours

Semolina and rimacinata (re-milled semolina) are used for pasta and for dusting pizza peels. Gluten-free flour blends let you offer a gluten-free line, but they need their own recipes and separate handling to avoid cross-contact.

Buying flour in bulk: practical tips

• Match the bag to your usage. A 20–25 kg sack is the cheapest per kilo, but only if you use it before it goes stale. Small cafés may be better off with cases of 1 kg bags.
• Store it right. Keep flour sealed, off the floor, in a cool, dry place away from strong smells. Rotate stock first-in, first-out.
• Plan for weight. Flour is heavy, so shipping is calculated by weight. Combining flour with your other supplies in one order makes the most of free delivery thresholds.
• Keep the spec sheet. Note the brand and type that works for each product so every batch comes out the same.
