Introduction:Colombian coffee is renowned worldwide for its balanced and delicate flavors. Its rigorous grading system and diverse regional characteristics serve as key references when selecting coffee beans. This article delves into the grading standards of Colombian coffee, from Supremo to Excelso, and explores the unique flavor profiles of the central MAM region and the Nariño region, helping you choose the most suitable coffee beans based on your pour over preferences.
Colombian coffee is known for its mild and delicate taste, with its grading system and regional features being focal points of interest for coffee lovers globally. From the highest grade of Supremo (SUPERMO) to the next level, Excelso (EXCELSO), each grade has clearly defined quality criteria, while altitude is a key factor influencing both flavor and grade.
Colombia primarily grows Arabica varieties, commonly known as small-bean coffee. Compared to the more common Robusta (large-bean coffee), Arabica offers a softer flavor with moderate acidity. Among the many Arabica variants, Colombian coffee beans, thanks to their uniform growing conditions and unique microclimates, produce a premium, delicate taste, often described as the "gentlemen of the coffee world."
The country’s coffee grading system is subdivided into over 200 categories, mainly based on bean size, altitude, and processing method. Among these, only Grade 18 beans with a diameter of 18/64 inch or more qualify as high-quality specialty coffee, which is also one of the basic requirements for Supremo and Excelso grades.
Although Colombian coffee is grown across a wide range of regions, the central area is the most famous. The three major producing regions—Medellín, Armenia, and Manizales—are customarily grouped together as "MAM." Coffee from these areas typically has a rich flavor and full body, making it a top choice for many baristas when performing pour overs.
Beyond the MAM regions, Nariño is also gradually making a name for itself. This high-altitude region produces coffee known for its bright acidity and complex floral notes, attracting attention in the international market. It is reported that Starbucks once secured exclusive purchasing rights for Nariño Supremo-grade coffee beans, further boosting the coffee’s prominence within the specialty coffee community.
Colombian coffee grades are mainly determined by cultivation altitude and are roughly divided into three to seven grades, measured in meters:
• Supreme beans: above 1,500 meters
• High-grade beans: 1,200 to 1,500 meters
• Medium-grade beans: 1,000 to 1,200 meters
• Supreme washed beans: 900 to 1,000 meters
• High-grade washed beans: 760 to 900 meters
• Premium washed beans: 610 to 760 meters
• Standard washed beans: below 610 meters
The higher the altitude, the slower the coffee grows, resulting in denser beans with richer flavors, brighter acidity, and pronounced sweetness—ideal for coffee enthusiasts who enjoy the delicate flavors of pour over. While lower-altitude coffee may be of a lower grade, it can still provide a full body and rich mouthfeel in certain blends.
In summary, understanding the grading and regional characteristics of Colombian coffee can help guide your selection. Whether you prefer the full-bodied taste of the MAM region or the high-altitude floral and fruity notes of Nariño, you can find the perfect coffee beans tailored to your personal pour over preferences.
