Why Brazil Doesn’t Have a No.1 Coffee Bean Grade

When you buy specialty coffee, you might assume that higher numbers mean better beans—like Jamaica’s Blue Mountain No.1. But if you’ve seen Brazilian coffee labeled ‘Santos #18 No.2’, you may wonder: why is No.2 better than No.1? And why are most Brazilian beans sized at 18 mesh? The truth lies in how Brazil grades its coffee—and why that system differs from global expectations.

Brazil does not grade its top coffee as No.1 because local standards consider no bean perfect. The highest commercial grade is No.2, even though No.1 exists. So when you see ‘Santos #18 No.2’, it means 18-mesh beans with the second-highest defect tolerance. That’s the top tier in Brazil’s system.

How Brazilian Coffee Is Graded

Brazil primarily uses two methods for grading green coffee: mesh size (bean diameter) and defect rate. Mesh size refers to the number of beans per unit area, with larger numbers indicating bigger beans. The maximum mesh size is 19, but 18 is most common for exported Brazilian coffee. Defect grading evaluates how many flawed beans are allowed per sample.

Why Most Brazilian Coffee Is 18 Mesh

The 18 mesh size is standard for Brazilian exports because beans that are too large—like those at 19 mesh—can cause uneven roasting, especially in blends. Roasters often use Brazilian beans as a base in blends, and inconsistent bean size leads to uneven heat absorption. While bean size doesn’t directly affect flavor, uniformity does impact roast quality. That’s why 18 mesh is the practical choice for both export consistency and roasting performance.

Why There’s No Brazilian No.1 Coffee Bean

Unlike Jamaica, where the prestigious Blue Mountain coffee has a No.1 grade, Brazil intentionally stops at No.2. The reasoning is cultural and practical: Brazilian coffee graders believe no bean is truly flawless. Even the best beans may have minor imperfections, so the top official export grade is No.2. This doesn’t mean No.1 beans don’t exist—they just aren’t used for export grading. In Brazil’s system, No.2 represents the highest commercial standard.

What Mesh Size Really Means for Coffee Quality

Mesh size mainly affects roasting consistency, not flavor profile. Larger beans like 19 mesh can roast unevenly, especially in blends with smaller beans. That’s why 18 mesh is optimal for balanced roasting. While some assume bigger beans mean better quality, in Brazil’s system, defect rate and roast suitability matter more than size alone. The focus is on producing coffee that roasts evenly and tastes balanced, whether as a single origin or blend component.

Frequently Asked Questions

Does Brazil produce No.1 grade coffee beans?

Brazil does have a No.1 grade internally, but it is not used for exported coffee. The highest official export grade is No.2, reflecting Brazil’s grading philosophy that no bean is perfect. This is different from other origins like Jamaica, which labels its top Blue Mountain coffee as No.1.

Why is 18 mesh the standard for Brazilian coffee?

18 mesh is the most common export size because it balances size and roast consistency. Beans sized at 19 mesh are too large and can roast unevenly, especially in blends. Most Brazilian coffee is used as a blend base, so 18 mesh ensures even roasting and compatibility with other beans.

Does bean size affect coffee flavor?

Bean size does not directly influence flavor. However, uniform size helps ensure even roasting, which impacts extraction and cup quality. In Brazil’s grading system, defect rate and roast performance are more critical to final coffee quality than mere size.

Why does Brazil not use No.1 as the top grade?

Brazilian grading standards reflect a belief that no coffee bean is entirely free of defects. Therefore, the top export grade is No.2, even though No.1 beans may exist. This contrasts with origins like Jamaica, where No.1 is the highest marketed grade.

What does ‘Santos #18 No.2’ mean?

This label means the coffee is 18 mesh in size (a common export grade) and graded as No.2, which is the highest official commercial grade in Brazil’s system. It indicates a specific balance of size and defect tolerance for export-quality beans.

Can I use Brazilian coffee as a single origin?

Yes. Brazilian coffee is often used for single origin brewing, especially when medium roasted. It typically shows balanced flavors with notes of nuts, chocolate, and mild acidity. FrontStreet Coffee offers several Brazilian single origin options suitable for pour-over, French press, and espresso.
