Colombia's AF Estate in Medellín: Coffee Varieties & Altitudes

If you’ve ever wondered what makes Colombian coffee from high-altitude estates like Medellín’s AF Estate stand out—especially those labeled EP 10%, Supremo, or Esmeralda—here’s where the details matter. This isn’t just about origin; it’s about how elevation, variety, and processing work together to define your cup.

In short: The AF Estate in Medellín grows mostly Arabica Caturra and Bourbon at 1400–1800m, with specific lots classified as EP 10% (1400–1600m), Supremo (1500–1800m), and Esmeralda (1500–1800m). These designations reflect both altitude and bean quality.

What Is the AF Estate in Medellín?

The AF Estate is a coffee-growing property located near Medellín, Colombia, situated within a well-known coffee-growing region of the country. While it may not yet be a globally famous name like some estates in Huila or Antioquia, it produces high-quality Arabica coffee at elevations that support slow maturation and complex cup profiles. The estate focuses on traditional varieties suited to the region’s conditions.

Which Coffee Varieties Grow at the AF Estate?

The estate primarily cultivates two classic Colombian coffee varieties: Caturra and Bourbon. Both are well-regarded for their balanced acidity, medium body, and clear fruit or floral tones. Caturra is a natural mutation of Bourbon known for higher yields and smaller tree size, making it easier to manage on steep slopes. Bourbon, meanwhile, is valued for its classic sweetness and cup complexity. These varieties thrive at the estate’s altitude range and are processed to highlight their inherent qualities.

What Are the Different Coffee Classifications from the AF Estate?

The AF Estate offers several classified lots, each defined by altitude and bean selection:

• EP 10%: Grown at 1400–1600m, this lot uses a blend of Caturra and Colombia varieties, with 10% of the beans meeting a stricter screen size or quality measure (the meaning of “EP 10%” likely refers to European Preparation with 10% oversize or premium selection). It is ideal for those seeking a balanced everyday cup with regional typicity.
• Supremo: Sourced from plants at 1500–1800m, this classification is made exclusively with Caturra. The Supremo grade indicates large bean size and high quality, often associated with a cleaner, more structured cup profile.
• Esmeralda: Also grown at 1500–1800m and made from Caturra, the Esmeralda lot may share similarities with the famed Panamanian Geisha-labeled Esmeralda in nomenclature only—but it denotes a selected, potentially floral or fruity lot, reflecting the estate’s aim for distinct offerings within the region.

Why Does Altitude Matter for Coffee from Medellín?

Altitude is one of the most critical factors influencing coffee flavor. At 1400–1800m, the AF Estate benefits from cooler temperatures and a slower ripening process. This extended maturation allows cherries to develop more sugars and complex acids, resulting in brighter acidity, greater sweetness, and more defined fruit or floral notes in the cup. The specific ranges for each classification (EP 10%: 1400–1600m, Supremo and Esmeralda: 1500–1800m) ensure that only beans meeting certain maturity and density criteria are selected.
