Colombian Coffee Varieties and Grade Breakdown

If you’ve ever wondered why some Colombian coffees taste balanced and smooth while others have bold regional character, the answer lies in both variety and grade. Colombia grows mostly Arabica—specifically smaller-seeded, higher-quality Typica-related cultivars—not the harsher Robusta common in Africa. But not all Colombian beans are equal: the country uses a detailed grading system based on bean size, density, and origin. So what makes a Colombian coffee 'special,' and how do you find the best ones?

In short: The highest-grade Colombian coffee is Supremo (17/64”+ beans), with Excelso just below. Only beans over 18/64” in the Supremo grade qualify as 'selected' specialty coffee. The best-flavored come from central regions like Medellin, Armenia, and Manizales (collectively called 'MAM'), and southern zones like Narino, known for bright, complex cups. Starbucks reportedly holds exclusive rights to Narino Supremo beans.

What Coffee Varieties Grow in Colombia?

Colombia’s coffee crop is overwhelmingly Arabica—Coffea arabica, the small-seed species also known as 'small coffee.' This contrasts with Coffea canephora (Robusta), the larger-seeded, more bitter variety typically grown in Africa, including Madagascar. Within Arabica, Colombia cultivates several Typica-related cultivars adapted to its terrain. Compared to Brazil’s larger, high-yield beans, Colombian coffee plants produce smaller seeds but with more refined cup quality, thanks to the country’s unique climate and elevation.

How Is Colombian Coffee Graded?

Colombia uses a 200+ level grading system with strong regional distinctions. The top official grade is Supremo—beans sized 17/64” (about 6.75mm) or larger. Just below that is Excelso, a slightly smaller bean grade. However, to qualify as 'selected' or truly specialty-grade Colombian coffee, beans must be Supremo and measure 18/64” (approximately 7.15mm) or more in diameter. This strict sizing correlates with bean density and often, cup quality.

Which Colombian Regions Produce the Best Coffee?

While coffee is grown throughout Colombia’s three main regions—northern, central, and southern—the most renowned flavors come from the central highlands and the southern zones. The 'MAM' group includes the well-known Medellin, Armenia, and Manizales regions, celebrated for full-bodied, structured profiles. In the south, Narino stands out for its vibrant, high-altitude beans that offer exceptional cup complexity. According to industry reports, Starbucks holds an exclusive purchase agreement for Narino Supremo beans, which frequently appear in their stores.

Why Does Elevation and Region Matter So Much?

Colombia’s mountainous geography creates a wide range of microclimates. The Andes split into three cordilleras, each offering volcanic, organic-rich soils and elevations between 800–2300 meters. Coffee trees grown at higher altitudes experience cooler temperatures, slower maturation, and more concentrated sugars and aromatic compounds. That’s why southern regions like Narino, often above 1500 meters, produce some of the country’s most sought-after beans. The consistent cloud cover and narrow diurnal temperature swings further slow ripening, enhancing cup quality.

Frequently Asked Questions

What are the main coffee bean varieties grown in Colombia?

Colombia primarily grows Arabica (Coffea arabica), specifically smaller-seeded cultivars related to Typica. Robusta (Coffea canephora) is rarely cultivated there, unlike in Africa. Colombian Arabica varieties are adapted to high altitudes and are known for finer cup characteristics compared to larger-beaned, higher-yield Brazilian beans.

How is Colombian coffee graded?

Colombian coffee is graded by bean size, with Supremo being the highest official grade (beans 17/64” or larger in diameter). Excelso is a slightly smaller grade. To be considered 'selected' specialty-grade coffee, beans must be Supremo and at least 18/64” (about 7.15mm) in diameter. This size indicates higher density and often better cup quality.

Which Colombian coffee regions are most famous?

The most famous regions are Medellin, Armenia, and Manizales—grouped as 'MAM'—known for full-bodied, balanced profiles. Southern regions like Narino are also highly regarded for bright, complex, and high-altitude coffees. Narino beans are so prized that Starbucks holds exclusive rights to Narino Supremo beans.

What does 'selected' coffee mean in Colombia?

'Selected' Colombian coffee refers to Supremo-grade beans that are 18/64” (approximately 7.15mm) in diameter or larger. These beans are considered premium due to their size, density, and typically superior cup characteristics, distinguishing them from standard Supremo or Excelso grades.

Why does altitude affect Colombian coffee flavor?

Higher altitudes in regions like Narino slow coffee cherry ripening due to cooler temperatures and significant day-to-night temperature shifts. This results in denser beans with more concentrated sugars and acids, leading to a more complex and flavorful cup compared to lower-grown beans.
