Overview¶

Bourbon is one of the two foundational Arabica coffee varieties, alongside Typica, and the genetic ancestor of numerous modern cultivated varieties including Caturra, Catuaí, Mundo Novo, Pacas, Villa Sarchi, and SL28. Originating from a distinct Yemeni Arabica population introduced to the island of Réunion (formerly Île Bourbon) around 1715–1718, Bourbon underwent genetic divergence through isolation before being re-introduced to East Africa and the Americas from the mid-nineteenth century. It remains highly valued in specialty coffee for exceptional sweetness and cup complexity, despite susceptibility to coffee leaf rust and lower productivity than modern varieties.

Historical Origins¶

Coffee was introduced to Réunion from Yemen by French colonists around 1715–1718. Isolated on the island for approximately one hundred years of cultivation, the population underwent genetic drift and natural selection, diverging from the Typica lineage and developing the morphological and cup characteristics that define Bourbon.

From Réunion, Bourbon spread: - 1860s–1870s: Introduced to Brazil - Late 1800s: Spread through Latin America - Early 1900s: Introduced to East Africa — Rwanda, Burundi, Tanzania - 1930s–1950s: Became a foundation variety in Central America

Plant Characteristics¶

Height: Medium, 2.5–3.5 metres; shorter and broader than Typica.

Leaves: Young tips are green (diagnostic characteristic; Typica produces bronze tips). Mature leaves broad with wavy edges.

Cherries: Round to slightly oval, larger than Typica; red when ripe in the standard form. Colour variants — Yellow Bourbon, Pink Bourbon, Orange Bourbon — occur as spontaneous mutations.

Branching: Wide lateral branch angles; bushy structure with shorter internodes than Typica.

Yield: 20–30% higher than Typica but significantly lower than modern compact varieties (Caturra, Catuaí, Catimor). Typical yield: 2,000–3,000 kg cherry per hectare under good management.

Biennial bearing: Moderate to strong tendency for alternating heavy and light crop years.

Altitude: Optimal range 1,200–1,800 metres; expresses best cup quality at higher elevations where cherry maturation is slower.

Disease Susceptibility¶

Bourbon is highly susceptible to Coffee Leaf Rust (Hemileia vastatrix), coffee berry disease, and root nematodes. The Central American rust epidemic of 2008–2013 drove significant replacement of Bourbon with disease-resistant varieties across the region. Maintaining Bourbon requires fungicide programmes, active monitoring, and higher management costs than resistant varieties.

Cup Quality¶

Bourbon is known for: - Sweetness: Complex, distinctive sweetness — brown sugar, caramel, honey; a signature characteristic that distinguishes it from Typica - Acidity: Balanced and pleasant; bright citrus to mellow stone fruit depending on altitude, origin, and processing - Body: Medium to medium-full; smooth texture - Flavour notes: Caramel, toffee, brown sugar, milk chocolate, stone fruit (apricot, peach, plum), red fruit (cherry, apple), almond - Complexity: Layered profile that evolves as the cup cools

Well-processed Bourbon typically scores 83–88 on the SCA scale; exceptional lots from ideal altitudes reach 89–91+.

Regional Expression¶

El Salvador: The country with the highest proportion of Bourbon cultivation globally (60–70%); Bourbon defines Salvadoran coffee identity.

Rwanda and Burundi: Bourbon is the dominant variety in both countries (70–90% of production), producing the bright, clean, complex profiles for which these origins are known in specialty markets.

Guatemala: Significant Bourbon presence, particularly in Antigua and Huehuetenango, though partially displaced by disease-resistant varieties.

Brazil: Yellow Bourbon is an important Brazilian specialty variety; standard red Bourbon largely replaced by higher-yielding cultivars.

Colour Variants¶

Yellow Bourbon: Produces yellow cherry rather than red; associated with pronounced sweetness and mild acidity in the cup. Important in Brazilian specialty production.

Pink Bourbon: A rare variety; disputed genetics (possibly not true Bourbon in all reported instances); described as exceptionally sweet when authentic.

Orange Bourbon: A very rare mutation.

Varieties Descended from Bourbon¶

Bourbon's genetics underpin many of the world's most important coffee varieties:

Variety	Derivation
Caturra	Spontaneous dwarf mutation of Bourbon (Brazil, c.1915–1935)
Pacas	Independent dwarf mutation (El Salvador, 1949)
Villa Sarchi	Independent dwarf mutation (Costa Rica, 1950s)
Mundo Novo	Natural Bourbon × Typica hybrid (Brazil, discovered 1943)
Catuaí	Mundo Novo × Caturra cross (Brazil, released 1972)
SL28	Scott Laboratories selection from a Bourbon-lineage Tanganyika drought-resistant variety (Kenya, 1931)
Catimor	Caturra × Timor Hybrid (disease-resistant cross)
Sarchimor	Villa Sarchi × Timor Hybrid (disease-resistant cross)

Key Facts¶

Bourbon is a foundational Arabica variety introduced to Réunion c.1715–1718; 100 years of island isolation produced genetic divergence from the Typica lineage
Cup quality signature: pronounced sweetness, balanced fruit acidity, medium-full body; scores 83–91+ SCA
Highly susceptible to coffee leaf rust; requires active disease management; largely replaced in Central America after the 2008–2013 epidemic
El Salvador, Rwanda, and Burundi maintain the highest proportions of Bourbon cultivation
Parent variety of Caturra, Catuaí, Mundo Novo, Pacas, Villa Sarchi, SL28, and by extension most modern compact and hybrid Arabica varieties
