Aterra Mills vs. typical US flour

Read the ingredient list. That's the difference.

Most all-purpose flour in the US is bleached and enriched with synthetic vitamins and iron. Ours is wheat. That's it.

What's in the bag

Flour with a passport.

T55 is a French classification based on how much mineral (ash) stays in the flour after milling. It gives you the silky, extensible dough French bakers use every day for baguettes, croissants and brioche. And because it swaps 1:1 for all-purpose, your cakes and quick breads come out lighter too.

Love it!

Honestly didn't expect much but this flour is really good. My bread has been coming out way better since I switched. Better crust, better texture, just overall more consistent. The 5kg bag lasts a while too. Will definitely keep buying it.

Excellent quality flour

You can tell the difference right away: lighter dough, better rise, and a cleaner flavor overall. I use it for bread and croissants mostly, and both have improved significantly. The 5kg bag is great for serious home bakers.

A versatile and balanced flour

French flours are known for their refined milling standards and consistency, which make French pastries so famous. This one produces yummy baked goods every time.

Nice upgrade from regular flour

In terms of quality and texture, it feels very fine and consistent, and it behaved predictably in my recipes. The lemon lavender loaf cake and chocolate chip banana bread I made both rose well and had a tender crumb.

Our story

It started with my sister's sourdough.

I come from a European family where food is a big deal. My sister bakes sourdough, and she noticed her bread came out completely different depending on the flour. Better rise, better texture, lighter.

We started reading labels. Most US flour is bleached and enriched with synthetic additives. The flour European families have trusted for generations is simply wheat.

Aterra Mills, "from the earth", brings that flour from French farms straight to American kitchens.

Common questions

Everything you need to know.

What exactly is T55 flour?

T55 is a French milling classification based on ash (mineral) content, 0.50 to 0.60%. It is finely milled with low bran, which gives a silkier dough and more consistent results than standard all-purpose flour.

Can I substitute it 1:1 for all-purpose flour?

Yes. Protein is 10 to 11%, close to all-purpose. For bread, start with slightly less water than your recipe calls for and adjust from there.

How does the guarantee work?

If you are not happy with your first bag, email us within 30 days of delivery and we'll refund it. You don't need to return the bag.

How does the subscription work?

You save 10% on every delivery and choose how often it ships. Skip, change or cancel anytime from your account. No commitment.

How long does shipping take?

Orders ship from Miami, FL within 1 to 2 business days. Shipping is free on 2 or more bags.

Is it gluten-free?

No. It is wheat flour and contains gluten. It is not suitable for people with celiac disease or a wheat allergy.

Why does it cost more than supermarket flour?

It is imported from France, made with traceable wheat, and has nothing added. Per loaf, it works out to under $4.

How should I store it?

Keep it sealed in a cool, dry place. A 5 kg bag usually lasts 4 to 6 weeks for someone baking 2 to 3 times a week.
