Oldest Coffee Varieties: Typica and Bourbon Origins

When you sip a cup of single-origin coffee and wonder why it tastes the way it does, part of the answer lies in the plant’s genetic lineage. Many of the world’s most respected specialty coffees trace back to just two ancient Arabica varieties: Typica and Bourbon. These two parent varieties, cultivated for centuries, gave rise to nearly all the beloved cultivars used in high-end coffee today.

There are over 100 known coffee varieties, but Typica and Bourbon are the oldest Arabica types, originating in Ethiopia and Yemen respectively. They spread across the globe, especially to Central and South America and Asia, evolving into the diverse range of specialty coffee plants we know today—including varieties grown in Yunnan, China, which descend from Typica.

The Origins: Typica and Bourbon

Typica is the earliest known coffee variety from Ethiopia. All modern Arabica coffee varieties descend from it. Typica trees have bronze-tipped leaves and oval or thin, pointed beans. The flavour is elegant but the plant is delicate—low-yielding and highly susceptible to disease. Despite these weaknesses, elite versions of Typica are cultivated in famous regions. Examples include Jamaica Blue Mountain, Sumatra Mandheling, and Hawaii Kona.

Bourbon, meanwhile, originated as a mutation of Typica after it was brought to Yemen. The beans changed from pointed to more rounded. In 1715, French missionaries transported Yemeni Typica-like beans to the island of Bourbon (now Réunion) off East Africa, leading to the new name. By 1727, it reached Brazil and other parts of Central and South America, and in 1732 it was taken to Saint Helena Island (where Napoleon was imprisoned). Bourbon is known for consistently high cup quality and is a favourite in specialty coffee competitions across the Americas.

Mutations of Typica and Bourbon

Over time, natural and cultivated mutations of Typica and Bourbon have produced several notable specialty coffee varieties. Each comes with unique bean shape, yield, disease resistance, and flavour profiles.

• Bourbon (Bourbon Pointu or Lavado Fine): Discovered in 1810 on Bourbon Island, this rare mutation features an elongated, pointed bean shape and about half the caffeine content of regular coffee. It’s extremely fragile, low-yielding, and mostly found in lab settings.
• (Maragogype or Elephant Bean): First found in Brazil’s Bahia state in 1870, this Typica variant produces beans roughly three times larger than normal Arabica beans. It performs poorly at low altitudes but can deliver mild acidity and sweet flavours when grown at elevation.
• (Geisha): A Typica-family variety originally from the Geisha region of Ethiopia (southwest Ethiopia, near the town of Gesha), it gained little attention until planted in Panama during the 1960s. It rose to fame after 2005 due to exceptional cupping scores.
• 'SL28' 'SL34': Developed in the early 20th century by British and French researchers in Kenya, these Bourbon descendants thrive in Kenya’s high-phosphate soils. They produce the country’s signature bright, complex acidity—but don’t perform well outside Kenya.
• Bourbon (Yellow Bourbon): Found in São Paulo state, Brazil, this Bourbon mutation ripens to an orange-yellow colour rather than red. Other yellow-fruited Bourbon variants have also been found in the region.
• Caturra (Caturra): A natural single-gene mutation of Bourbon, discovered in Brazil in the 1950s. It offers better yield and disease resistance than Bourbon, doesn’t require shade, and has comparable or slightly inferior cup quality.
• (Pacas): Found in El Salvador in 1935, this Bourbon mutation was identified in 1956 after a farmer noticed higher yields. It’s now recognised as a distinct genetic mutation.
• Sarchi: A Bourbon variant discovered in the 1960s in Costa Rica, frequently appearing in high-scoring cuppings in recent years.

Hybrid Varieties from Arabica Parents

In addition to mutations, controlled crosses between different Arabica varieties have produced hybrids with improved traits for farming and flavour.

• (Mundo Novo): A natural cross between Bourbon and Typica, first found in Brazil. It’s high-yielding, resistant to pests, and became a backbone of Brazilian coffee in the 1950s—but the trees are tall and hard to harvest.
• Catuai (Catuai): A cross between Mundo Novo and Caturra. It’s shorter, wind-resistant, but often considered less complex in flavour.
• Pacamara (Pacamara): A cross between Pacas and Maragogype, developed in El Salvador in the 1950s. It produces very large beans, second only to Elephant Bean, and has earned strong cupping results in recent years.
• (Kent): An Indian Typica hybrid with high yield and disease resistance, though it hasn’t performed well in cupping competitions.

Hybrids Between Arabica and Robusta (Canephora)

Crosses between Arabica and the more robust, bitter Robusta species (Coffea canephora) were typically aimed at improving yield and disease resistance, often at the expense of cup quality.

• (Timor): A natural hybrid found in East Timor with 44 chromosomes, closer to Arabica but known for neutral flavour.
• (Catimor): Created in 1959 by crossing Caturra with Timor. It’s highly resistant to rust but generally regarded as having poor cup quality. It’s widely used in commercial coffee production.
• (Icatu): A multi-generation Brazilian hybrid that once ranked in the top ten of Brazil’s “Cup of Excellence.”
• 11 (Ruiru 11): Developed in Kenya in 1985, this high-yield hybrid prioritises quantity over quality. Hybrids between Arabica and Robusta are not considered specialty-grade, though some are used in lower-quality blends.

Frequently Asked Questions

What are the two oldest Arabica coffee varieties?

The two oldest known Arabica coffee varieties are Typica, originating in Ethiopia, and Bourbon, which evolved from Typica after being taken to Yemen. All modern Arabica varieties are descendants of these two.

Where did Typica coffee originate?

Typica originated in Ethiopia and is the parent variety of almost all Arabica coffee. It was taken to various regions and mutated into many sub-varieties, including those grown in places like Jamaica and Hawaii.

What is special about the Bourbon coffee variety?

Bourbon originated as a mutation of Typica in Yemen and was later taken to Bourbon Island (now Réunion). It has rounder beans than Typica and is known for high cup quality, making it a favourite in specialty coffee regions in the Americas.

What are some notable mutations of Typica and Bourbon?

Notable mutations include Elephant Bean (Maragogype), which has very large beans; Bourbon Pointu, which has low caffeine; Geisha, renowned for high cup quality; and Yellow Bourbon, which ripens to an orange-yellow colour.

Are there any high-quality Arabica-Robusta hybrids?

Most Arabica-Robusta hybrids, such as Catimor and Ruiru 11, were bred for disease resistance and yield, not flavour. They are generally not considered specialty-grade, though some are used in commercial blends.

Which coffee varieties are linked to high cup quality?

Varieties like Geisha, SL28, SL34, and Bourbon are associated with high cup quality, especially when grown in their ideal environments. Many have won awards in global cupping competitions.
