Whoever spends time in specialty coffee will sooner or later come across names such as Geisha, SL28, or Pink Bourbon. These refer to coffee varieties — genetic subtypes within the Coffea Arabica species.

An important distinction: this article focuses exclusively on Arabica varieties. While several coffee species exist worldwide — most notably Arabica and Robusta — specialty coffee is overwhelmingly dominated by Arabica. The reason is simple: Arabica generally offers greater aromatic complexity, more refined acidity structures, a wider range of flavor nuances in the cup, and significantly lower caffeine content.

So when names such as Bourbon, Caturra, or Geisha appear on specialty coffee bags, they almost always refer to varieties within the Arabica species.

Of course, flavor and quality are never determined by genetics alone. Altitude, climate, soil, harvesting methods, processing, and brewing all play a major role. Still, the variety itself often provides a useful first indication of where a coffee's flavor profile is likely headed.

Africa – Floral, Complex, Vibrant Acidity

African coffees, especially from Ethiopia and Kenya, are often known for their high aromatic complexity and expressive fruit characteristics.

Typical cup profile: Floral, juicy, and complex.

Central America – Balance and Sweetness

Many of the classic varieties in specialty coffee originate from Central America and continue to form the foundation of countless coffee farms today.

Typical cup profile: Clean, sweet, and balanced.

South America – Chocolate Meets Fruit

Brazil and Colombia have long shaped many classic specialty coffee profiles, although both origins are now increasingly experimenting with new varieties.

Peru is also an origin worth paying attention to. In recent years, the country has seen major investment in specialty coffee: more microlots, stronger quality focus, improved processing methods, and increasingly exciting varieties such as Geisha and Bourbon. As a result, Peruvian coffees are appearing more frequently in international competitions and on the menus of specialty roasters around the world.

Typical cup profile: Sweetness, chocolate, and increasingly exotic fruit notes.

Asia & Pacific – Spice and Body

In regions such as Indonesia, India, and Papua New Guinea, quality often goes hand in hand with a focus on resilient plant varieties.

Typical cup profile: More spice, fuller body, often earthy.

Arabica Varieties Worth Knowing – Quick Overview

If you see these names on a specialty coffee bag, they are worth a closer look:

• Geisha → Floral, tea-like, complex
• SL28 → Berry notes, vibrant acidity
• Bourbon → Sweet and balanced
• Typica → Elegant and clean
• Pacamara → Large, fruity, distinctive

Conclusion

In specialty coffee, we are almost always talking about Arabica — and within that species, about different varieties. They are not a guarantee of flavor, but they provide useful orientation. Once you start paying attention to varieties, patterns quickly begin to emerge, helping explain why two coffees from the same country can taste completely different.

The name printed on a coffee bag is often already the first clue about what will eventually end up in your cup.
