Why Coffee Bean Size Matters More in Colombia Than You Think

If you’ve ever bought Colombian coffee labeled "Supremo" thinking it’s the best, you’re not alone—but you might be disappointed. The truth? Size (17–18 mesh) doesn’t guarantee great flavor. Many so-called "Supremo" beans come from commercial blends with no origin listed, often the lower-grade MAM. For real quality, ignore the mesh size and look at where the coffee comes from.

The key to great Colombian coffee isn’t the bean grade—it’s the region and variety. Southern high-altitude zones like Huila, Popayán (Cauca), and Tolima produce superior lots with bright acidity, berry notes, caramel, and rich sweetness. If the bag doesn’t name a province or farm, it’s likely a generic commercial lot—not specialty.

Colombia’s Coffee Regions: Where Quality Lives

Colombia’s finest specialty coffee grows mainly in the southern highlands, above 1,500 meters. Key areas include:

• Huila (e.g., San Agustín)—known for delicate acidity, berry, and caramel tones
• Cauca (Popayán)—produces vibrant, complex profiles
• Tolima—another high-altitude zone yielding sweet, structured cups

These regions explicitly label their beans by province or farm name. If your coffee bag lacks that detail, chances are it’s a blended MAM grade, not a single-origin specialty lot.

Why Bean Size Misleads: Typica vs. Hybrids

Colombia historically grew Typica (including the large Maragogype 'elephant bean' variant), prized for its size and flavor—but low yields and disease susceptibility made it nearly extinct by the 1980s. By 1970, Caturra had replaced most Typica due to better disease resistance and higher productivity. Then in 1982, the hybrid Colombia variety (Castillo’s predecessor) took over, further pushing Typica to just 20% of production today.

The irony? While modern varieties yield more and resist disease, many specialty roasters and cuppers agree: the classic Typica-based coffees once defined Colombia’s premium reputation. Today, those complex, high-acid profiles are mostly found in legacy farms or small southern lots sticking to traditional varieties.

What Really Determines Coffee Flavor

Here’s the breakdown of what actually affects Colombian coffee quality:

• Region: Southern departments (Huila, Cauca, Tolima) at 1,500+ meters produce the most awarded, flavorful profiles.
• Variety: Caturra dominates modern lots; Typica and Maragogype exist but are rare.
• Processing: Almost all Colombian coffee is washed (wet-processed), resulting in clean, blue-green beans—but appearance alone doesn’t predict cup quality.
• Bean Grade: Supremo (17–18 mesh) is large but not inherently better. Many commercial MAM beans also fall into this size range with no origin details.

Cupping data consistently shows southern Caturra lots—especially from Huila farms—winning national and international competitions. Mesh size matters far less than traceability and terroir.

Frequently Asked Questions

Does Supremo mean better coffee?

No. Supremo refers only to bean size (17–18 mesh) under Colombia’s grading system. Many Supremo beans are commercial-grade MAM with no origin, often blended and bland. Specialty quality depends on region and farm, not size.

Why is Colombian coffee not as good as it used to be?

Most experts blame the shift from traditional Typica to disease-resistant hybrids like Colombia and Caturra. While these varieties improved yield and durability, many palates find them less complex and vibrant than the classic Typica-based coffees of the past.

Which Colombian coffee regions produce the best specialty beans?

The southern regions—Huila, Cauca (especially Popayán), and Tolima—consistently produce the highest-rated specialty lots. These areas grow at 1,500+ meters and often specify origin on the bag, a sign of quality commitment.

Is Typica still grown in Colombia?

Yes, but rarely. Typica and its large-bean variant Maragogype once dominated, but now account for only around 20% of Colombia’s crop due to low yields and disease vulnerability. Most surviving Typica is in heritage farms or specialty micro-lots.

Does washed processing affect Colombian coffee flavor?

Yes. Almost all Colombian coffee is washed (wet-processed), which results in clean, bright cups with a typical blue-green bean color. However, processing alone doesn’t guarantee quality—origin and variety are bigger factors.

What coffee mesh size is considered premium in Colombia?

Supremo (17–18 mesh) is graded as premium based on size. But many Supremo beans are commercial MAM with no origin. Specialty buyers prioritize traceable regional lots over size alone.
