Ancient Coffee Varieties: The Original Arabica Types

When you’re exploring specialty coffee, you’ll often hear terms like Typica, Bourbon, and Geisha—but what do they really mean? These aren’t just names on bags, they are among the earliest and most influential coffee varieties, forming the genetic backbone of much of the world’s high-quality Arabica coffee.

There are at least 100 known coffee varieties in the Coffea genus, but when it comes to specialty coffee, most trace back to just two: Typica and Bourbon. These, along with a handful of their natural mutations and hybrids, represent the core of classic, high-elevation Arabica cultivation.

The Core Ancient Coffee Varieties

Specialty coffee mainly comes from carefully grown, high-altitude Arabica plants. Within this group, a few historic varieties stand out—not just for their age, but for the unique flavours and growing traits they’ve passed down. The most important of these are the ‘ancient’ or ‘original’ Arabica types, beginning with Typica and Bourbon.

Typica

Typica is the oldest known Arabica variety, originating in Ethiopia. Every other Arabica variety descended from it, either directly or indirectly. It has bronze-tipped leaves and typically produces oval or slightly pointed beans. Typica is known for its delicate, clean flavour profile, but it’s also very susceptible to disease and has low yields. Despite its weaknesses, it’s the parent of many classic coffees, including Jamaica Blue Mountain, Sumatra Mandheling, and Hawaii Kona—all estate-grown Typica varieties.

Bourbon

Bourbon originated as a natural mutation of Typica after it was taken to Yemen. The beans changed from pointed to rounded, and the plant was later taken to Bourbon Island (now Réunion) in 1715. From there, it spread to Brazil by 1727 and to the island of Saint Helena by 1732. Bourbon produces rounder beans and is favoured for its balanced cup, often excelling in cupping competitions across the Americas. It’s a reliable producer of sweet, complex flavours and remains one of the most important foundation varieties in specialty coffee.

Natural Mutations of Arabica

Over time, some Arabica plants mutated naturally, creating distinct varieties with different bean shapes, cup profiles, and growth characteristics. These genetic mutations—some rare, others more common—have played a big role in diversifying specialty coffee beyond Typica and Bourbon.

Bourbon Pointu (Slender Bourbon)

Discovered in 1810 on Bourbon Island, this rare mutation features slender, pointed beans and has roughly half the caffeine content of regular coffee. It’s known for exceptional cup quality but is extremely delicate, with low yield and poor disease resistance. Most examples are found only in lab settings or highly controlled environments.

Maragogype (Elephant Bean)

This mutation was first found in Brazil’s Bahia region in 1870. Maragogype beans are at least three times larger than standard Arabica beans, hence the nickname ‘elephant bean.’ While low-altitude-grown examples often lack complexity, high-altitude Maragogypes can produce sweet, smooth cups with gentle acidity and pleasant aromatics.

Geisha (Gesha)

Originally from the Gesha region of Ethiopia (whose name is coincidentally similar to the Japanese word for geisha), this Typica-family variety was brought to Panama in the 1960s and remained obscure until it won major cupping competitions around 2005. Now celebrated globally, Geisha is known for its jasmine-like floral notes, citrus brightness, tea-like body, and exceptionally high cup quality.

Kenyan SL28 and SL34

Developed by British and French researchers in Kenya during the early 20th century, these two Bourbon-related varieties were selected specifically for Kenya’s high-phosphorus soils. They produce some of the world’s most distinctive coffees, with pronounced high acidity, complex fruit notes, and deep sweetness. Though they thrive in Kenya, they typically underperform when grown elsewhere.

Yellow Bourbon

This Brazilian variation of Bourbon ripens to an orange-yellow colour instead of red. It’s otherwise similar to standard Bourbon but offers visual distinction and sometimes subtle flavour differences. Other yellow-fruited Bourbon variants have also been observed in Brazil.

Caturra

Discovered in Brazil during the 1950s, Caturra is a natural single-gene mutation of Bourbon. It’s more compact than Bourbon, easier to harvest, and shows better disease resistance—though its cup quality is generally on par with or slightly below Bourbon.

Pacas

First identified in El Salvador in 1956, Pacas is another natural mutation of Bourbon. It was discovered after a farmer noticed higher yields from a particular tree. Though related to Bourbon, it has a distinct enough profile to be considered its own variety, often used in blends or as part of specialty lots.

Villa Sarchi

This dwarf mutation of Bourbon was found in Costa Rica in the 1960s. Its small size makes it easier to harvest, and it has gained attention in recent years for appearing consistently in high-scoring cupping tables.

Hybrids Within Arabica (Intraspecific)

Breeders have also created hybrids by crossing different Arabica varieties to combine desirable traits such as yield, disease resistance, and cup quality. These intraspecific hybrids are all Arabica-to-Arabica crosses, and while they vary in flavour, some have earned respect in specialty circles.

Mundo Novo

A natural cross between Bourbon and Typica, Mundo Novo was first found in Brazil. It offers high yields and strong resistance to pests and disease, but its taller trees make harvesting more difficult. It became a workhorse variety in Brazil during the mid-20th century.

Catuai

A cross between Mundo Novo and Caturra, Catuai was bred for its compact growth and wind resistance. It’s widely planted in Central and South America but is often criticised for having a simpler flavour profile compared to its parents.

Pacamara

This hybrid of Pacas and Maragogype was developed in El Salvador in the 1950s. It produces very large beans—second only to pure Maragogype—and has earned positive cupping results in recent years for its balance and complexity.

Kent

Discovered in India, Kent is a hybrid of Typica with unknown parentage. It’s valued for its high yield and disease resistance, especially to leaf rust, but it hasn’t achieved notable success in specialty cupping evaluations.

Arabica × Robusta Hybrids (Interspecific)

Hybrids between Arabica and the harsher, more disease-resistant Robusta (Coffea canephora) were created to improve hardiness. However, these interspecific crosses usually sacrifice cup quality and are rarely considered specialty-grade. Most are used in commercial or blended coffees rather than single-origin offerings.

Timor

Found in East Timor, Timor is a natural hybrid with 44 chromosomes, closer to Arabica than Robusta. While it offers disease resistance, its flavour is generally considered bland and unremarkable.

Catimor

Developed in Portugal in 1959 by crossing Caturra with Timor, Catimor is highly resistant to coffee leaf rust. It’s widely cultivated for commercial production but is typically excluded from specialty coffee due to its often harsh or flat cup profile.

Icatu

A multi-generation Brazilian hybrid, Icatu has appeared in the top ten of Brazil’s Cup of Excellence competition, showing that careful breeding can still produce respectable cups even from interspecific lines.

Ruiru 11

Developed in Kenya in 1985, Ruiru 11 was bred primarily for high yield and disease resistance, with little focus on cup quality. It’s rarely seen in specialty contexts.

Frequently Asked Questions

What are the original coffee varieties in specialty coffee?

The original coffee varieties most important to specialty coffee are Typica and Bourbon. These two originated in Ethiopia and Yemen respectively, and nearly all high-quality Arabica coffees trace their lineage back to one or both of them.

What is the difference between Typica and Bourbon coffee?

Typica has oval or slightly pointed beans and bronze-tipped leaves, and is known for a clean, delicate flavour but low yield and poor disease resistance. Bourbon has rounder beans, higher yields, and often produces sweeter, more complex cups, with better overall plant vigour.

What is Geisha coffee and where does it come from?

Geisha (or Gesha) is a rare coffee variety originating from the Gesha region of Ethiopia. It gained global fame after being planted in Panama and winning major cupping competitions around 2005. It’s known for its floral, citrusy, and tea-like profile with exceptional sweetness and acidity.

Are Maragogype beans better than normal Arabica beans?

Maragogype beans are much larger than standard Arabica beans, but size alone doesn’t determine quality. When grown at high altitudes, they can produce smooth, sweet, and aromatic cups, but at lower altitudes, they often lack complexity and are not considered superior.

Why are Kenyan SL28 and SL34 so special?

SL28 and SL34 were developed in Kenya to thrive in high-phosphorus soils. They’re renowned for their bright acidity, intense fruit flavours, and deep sweetness—qualities that make them stand out in global cupping competitions, though they perform best only in Kenya.

Are Arabica-Robusta hybrids considered specialty coffee?

No, hybrids between Arabica and Robusta (such as Catimor or Timor) are generally not considered specialty coffee due to their typically lower cup quality, despite offering benefits like disease resistance and higher yields.
