Caramel and milk chocolate sweetness, a rounded body, and at high altitude a lift of stone fruit, citrus or flowers. That's Bourbon at its best, and it comes with a long family tree attached.
Bourbon is one of the most important varieties in the history of arabica. It takes its name from Île Bourbon, now Réunion, where coffee plants brought from Yemen were cultivated from the early 1700s. From there it spread to Brazil and across Latin America, and it became the starting point for a long list of varieties still grown today.
It comes with a familiar trade-off. Bourbon can make excellent coffee, particularly at higher elevations, but the plants are relatively low-yielding and susceptible to several major coffee diseases. That has made it less attractive for large-scale production, though it remains important in specialty coffee and in breeding programmes around the world.
From Réunion to Latin America
The story of Bourbon begins on the island of Bourbon, a French colony in the Indian Ocean now known as Réunion. According to World Coffee Research, the French made three attempts to bring coffee from Yemen to the island, in 1708, 1715 and 1718, and recent genetic studies back that up. Plants from the second and third attempts survived, and the population that developed there became known as Bourbon.
Bourbon stayed on the island for roughly 150 years. From the middle of the 19th century, French missionaries carried it to new footholds in Africa and the Americas. It reached Brazil around 1860, near Campinas, and spread north through South and Central America from there.
Once established in Latin America, Bourbon met other coffee populations and became part of an increasingly tangled family tree. Some varieties were natural mutations of Bourbon, while others were crosses involving Bourbon and other arabica populations. Caturra, Pacas and Villa Sarchi are all naturally occurring Bourbon mutations with a dwarf growth habit.
Bourbon in East Africa has its own history. WCR notes that many Bourbon-like varieties are now found there, but they don't necessarily match the Bourbon traditionally grown in Latin America.
The Bourbon family tree
The Bourbon family tree
Bourbon
One of the most culturally and genetically significant arabica varieties. Bourbon sits alongside Typica as a descendant of Yemeni seed, and it tends towards sweeter, more rounded cups with very good quality potential at high altitude. Yields are lower than modern hybrids and disease resistance is poor, but it remains prized in specialty coffee. Parent or ancestor to Caturra, Pacas and Mundo Novo, and related to SL28.
What does a Bourbon plant look like?
Bourbon is a tall coffee plant with relatively wide branching. The cherries tend to be rounder than those of Typica, and the beans are average in size for arabica. Young leaves are generally green, although individual Bourbon populations can show some variation.
Caturra, Pacas and Villa Sarchi carry a mutation that gives them a compact growth habit. Bourbon doesn't, and it's naturally tall. The plants need more room and can be harder to manage and harvest than dwarf or compact varieties.
WCR rates Bourbon's yield potential as medium. That's one reason it has gradually been replaced by more productive varieties in many commercial coffee-growing areas. In Latin America, varieties descended from Bourbon, including Caturra, Catuaí and Mundo Novo, now account for much of the production that was once based on traditional Bourbon itself.
Red, yellow, orange, pink and striped Bourbon
You'll often see Bourbon described by the colour of its ripe cherries. The differences are real, but they don't give us a simple set of rules for how the coffees will taste. Flavour is shaped by far more than cherry colour, including genetics, altitude, climate, harvesting and processing.
Red Bourbon is the classic form of the variety, with red cherries when ripe, widely cultivated across Latin America and East Africa.
Yellow Bourbon is a well-established selection, particularly associated with Brazil. It's believed to have first appeared around 1930 on a Red Bourbon farm near Pederneiras in São Paulo state. By 1942, Carlos Arnaldo Krug and his colleagues at the Instituto Agronômico in Campinas had shown that yellow fruit is controlled by a single genetic factor, which they named xanthocarpa. Where Yellow Bourbon itself came from is still open. It may be a mutation of Red Bourbon, or a natural cross between Red Bourbon and Amarelo de Botucatu, a yellow-fruited Typica.
Orange Bourbon is usually described in the trade as a natural colour mutation of Red Bourbon, and it's strongly associated with El Salvador. The published genetics are much thinner than they are for Yellow Bourbon, and whether the same colour factor is involved isn't settled.
Striped Bourbon is the newest name in the line-up: cherries with pale and dark bands running from stem to tip, sold as separated lots from several farms in Colombia. At Finca La Huella in Nicaragua, Orange Bourbon trees ripen either solid orange or striped, and the two make noticeably different coffees from the same land and the same washed process. There's no published genetic study on what a stripe means, so for now it's a description rather than a variety. We went deep on this in what colour tells you about a coffee cherry.
Pink Bourbon is more complicated. It has traditionally been described in the trade as a Bourbon-related variety, often as a cross or mutation involving Red and Yellow Bourbon. Genetic testing tells a different story. In 2017, two plants sold as Pink Bourbon came back closest to wild Ethiopian coffee, and in 2023 RD2 Vision's Christophe Montagnon concluded that Pink Bourbon is an Ethiopian landrace with nothing to do with Bourbon. Of the five samples tested that year, only one was pure Pink Bourbon, and the rest were mixed with Bourbon or Catimor. That doesn't settle the identity of every coffee sold under the name, but it does mean the name shouldn't be treated as proof of Bourbon ancestry.
Pink Bourbon has become particularly well known in Colombian specialty coffee, where high-altitude lots are often intensely floral and fruit-driven. Its popularity has grown faster than the scientific consensus around its ancestry, and that gap shows how variety names can drift in coffee.
What does Bourbon taste like?
There isn't one Bourbon flavour profile, but the variety has a strong reputation for quality. WCR rates Bourbon's quality potential at high altitude as very good.
In the cup, Bourbon is often associated with sweetness, balance and a rounded structure. Depending on the coffee, that might mean caramel, chocolate, stone fruit, citrus or floral flavours. The growing environment and processing method can shift the result considerably, so it makes more sense to think of Bourbon as leaning towards quality and balance than as having a fixed flavour profile.
Origin makes a difference too. Traditional Bourbon from Central America can taste quite different from Bourbon grown in East Africa, where different Bourbon-related populations, environments and processing traditions come into play. Even two Bourbon coffees from the same country can be markedly different.
Why isn't Bourbon grown everywhere?
The biggest problem is agronomy. Bourbon is susceptible to coffee leaf rust, coffee berry disease and nematodes. WCR currently rates its resistance to all three as low or susceptible.
A producer doesn't choose a variety on flavour alone. Yield, disease pressure, climate, labour, altitude and the cost of managing the farm all have to make sense together.
Bourbon's medium yield and disease susceptibility have encouraged farmers and breeders to look for alternatives. Some of the most successful have kept useful Bourbon characteristics while adding compact growth, higher productivity or disease resistance.
That's also why Bourbon is still found on farms where producers are prepared to manage those risks. At the right altitude and under the right conditions, the quality potential can make a lower-yielding variety worth growing.
Bourbon's genetic legacy
This is where Bourbon's influence becomes clear. It sits behind a large part of the arabica family tree cultivated across Latin America and Africa.
Caturra is a natural mutation of Bourbon discovered in Brazil between 1915 and 1918. A single-gene mutation gave it a compact growth habit, allowing plants to be grown more closely together and managed at a smaller size.
Pacas is another natural Bourbon mutation, discovered in El Salvador in 1949. Like Caturra, it carries the dwarfing mutation that gives it a compact structure.
Villa Sarchi appeared in Costa Rica in the 1950s or 1960s and is also a natural mutation of Bourbon. Its compact growth and ability to perform at high elevations made it useful in Costa Rican coffee and, later, in breeding programmes.
Mundo Novo has a different story. It's the result of a natural cross between Bourbon and Typica discovered in Brazil in 1943. Selections from that population became commercially important, and a later cross between Mundo Novo and Caturra produced Catuaí.
SL28, one of Kenya's best-known varieties, is Bourbon related too. It was selected in the 1930s from a population known as Tanganyika Drought Resistant, and WCR places it in the Bourbon-Typica genetic group.
There are many more examples. Once you start looking at the genealogy of arabica, Bourbon turns up again and again.
Why Bourbon still matters
Bourbon has been grown for centuries, and it still matters today. It remains one of the foundational varieties of modern arabica, with very good quality potential at high altitude and a genetic contribution that runs through countless other varieties.
It also shows why coffee varieties are always a compromise. The characteristics that make a variety desirable in the cup don't necessarily make it the easiest or most profitable plant to grow.
That balance between quality, yield and resilience explains much of coffee breeding over the last century. Bourbon is part of that story from the beginning, and plenty of the varieties developed since still carry something of its genetic legacy.
