Why Brazilian Coffee Beans Don’t Have a No.1 Grade

When you buy Brazilian coffee, you might see labels like ‘Santos #18 No.2’ — but why is there no No.1? And what does that number really mean for the beans you’re brewing? If you’ve ever wondered why your Brazilian beans are graded the way they are, or whether bigger beans taste better, this article breaks down the facts behind Brazil’s unique coffee classification system.

Brazilian coffee beans are commonly graded as No.2, not No.1 — because Brazilian coffee authorities don’t believe any bean is truly perfect. That’s why the highest official grade is No.2, even though No.1 exists for other origins like Jamaica’s Blue Mountain.

How Brazilian Coffee Is Graded

Most global coffee trading still relies on origin-based grading systems. In Brazil, the two most common methods are by bean size (measured in mesh or screen size) and by the ratio of defective beans. For example, a label like ‘Santos #18 No.2’ means the beans passed through an 18/64-inch (about 7.1mm) round hole sieve — the largest standard being 19/64-inch (No.19) — and were sorted to a No.2 defect standard, the highest commercial grade in Brazil.

Why No.1 Doesn’t Exist for Brazilian Beans

Brazilian coffee graders intentionally cap their top grade at No.2. The reasoning is straightforward: no coffee bean is flawless. Where other origins, such as Jamaica with its Blue Mountain No.1, award a No.1 grade, Brazil maintains that perfection is unattainable — hence, the best you’ll officially get is No.2.

Does Mesh Size Matter? Why Most Beans Are #18

A common question is whether larger beans — like No.19 — are better. In practice, 19-mesh beans are simply too big. Their larger size can cause uneven roasting, especially when used in blends where consistency matters. Most Brazilian beans are graded #18 because that size works well both for single-origin brewing and as a blending base. Importantly, bean size doesn’t strongly influence flavor — it’s more about roast uniformity and blend balance.

What Really Determines Coffee Quality

While mesh size and defect rates are useful sorting tools, they don’t tell you how the coffee will taste. Factors like processing method, altitude, varietal, and roast level matter far more for cup quality. Brazilian beans are known for their low acidity, balanced body, and notes of nuts, chocolate, and caramel — qualities that come out best with a medium roast.

Frequently Asked Questions

Why is Brazilian coffee graded No.2 and not No.1?

Brazilian coffee authorities consider no bean to be truly perfect, so they cap their top commercial grade at No.2. Other origins, like Jamaica with Blue Mountain No.1, do award a No.1 grade, but Brazil intentionally stops at No.2 as its highest official classification.

What does ‘Santos #18 No.2’ mean?

This label means the coffee beans are sized to pass through an 18/64-inch (approximately 7.1mm) sieve (No.18) and have been sorted to a No.2 defect standard, which is the highest grade in the Brazilian classification system.

Are 19-mesh coffee beans better than 18-mesh?

Not necessarily. While 19-mesh beans are larger, they are often considered too big for even roasting, especially in blends. Most Brazilian coffee is graded No.18 because that size offers a good balance for both single-origin and blend applications without compromising roast consistency.

Does bean size affect coffee flavor?

Bean size has minimal direct impact on flavor. Instead, factors like processing method, altitude, varietal, roast level, and brewing technique play a much larger role in determining the taste profile of the coffee.

Why are most Brazilian beans used in blends?

Brazilian beans are valued for their low acidity, chocolatey sweetness, and nutty body, making them an excellent base for espresso blends. Their consistency and balance help round out more vibrant or acidic beans in a mix.
