Bourbon Family Deep Dive¶

Overview¶

The Bourbon family encompasses Coffea arabica varieties descended from the Bourbon Island (now Réunion) population — a distinct Yemeni Arabica lineage that diverged from Typica on the island of Réunion (formerly Île Bourbon) in the Indian Ocean, and subsequently spread to East Africa, the Americas, and Japan. Bourbon and Typica are the two foundational Arabica lineages from which virtually all cultivated non-Ethiopian Arabica descends. Bourbon produces a genetic lineage notable for high cup quality — particularly sweetness, complex fruit acidity, and floral character — and has given rise to many of the world's most celebrated and commercially significant variety families, including Caturra, Catuaí, Pacas, Villa Sarchi, and SL28.

Origins of Bourbon¶

The Bourbon lineage originates from a separate introduction of Yemeni Arabica to Réunion (then Île Bourbon) — distinct from the Typica lineage spread via the Amsterdam Botanical Garden. Yemeni plants were brought to Réunion by the French around 1715–1718. Isolated on the island for approximately 100 years of cultivation, the Réunion population underwent genetic drift and selection, diverging from Typica and developing the characteristics that distinguish Bourbon from its ancestor.

Bourbon was subsequently re-introduced to Africa and the Americas: - East Africa: French missionaries brought Bourbon to Réunion's neighbour Zanzibar and thence to the East African mainland in the 1850s–70s; the variety became established in Kenya, Tanzania, and Rwanda - Latin America: Bourbon was brought to Brazil around 1860, and spread through the rest of Latin America through the late 19^th and early 20^th centuries

Key Varieties in the Bourbon Family¶

Bourbon¶

The reference variety; tall, higher-yielding than Typica, red or yellow cherry. Cup quality benchmark: bright, complex, fruit-forward acidity; pronounced sweetness; floral notes. See Bourbon Variety.

Caturra¶

A compact Bourbon mutation discovered in Minas Gerais, Brazil, around 1915–1935. Single recessive gene produces a dwarf plant form. High planting density (3,000–6,000 plants/ha); similar cup quality to Bourbon at altitude. Widely planted in Colombia, Brazil, and Central America. Parent of Catuaí. See Caturra.

Catuaí¶

A cross of Mundo Novo × Caturra developed by IAC (Brazil), released 1972. Compact (from Caturra), higher yield than Caturra, adapted to mechanised harvesting. The most widely planted variety in Brazil; also important in Central America. Cup quality slightly lower than Caturra or pure Bourbon at altitude but consistently adequate for commercial and specialty use.

Pacas¶

A compact Bourbon mutation from El Salvador (1949); same mutation as Caturra; adapted to Salvadoran highland conditions. Parent of Pacamara. See Pacas.

Villa Sarchi¶

A compact Bourbon mutation from Costa Rica (1950s); same mutation as Caturra and Pacas; well-adapted to cool, high-altitude Costa Rican conditions. Parent of Sarchimor. See Villa Sarchi.

Yellow Bourbon¶

A colour mutation of Bourbon producing yellow cherry instead of red; found in Brazil. Yellow-cherry Bourbon can produce a distinctly sweet and mild cup, though it is more susceptible to damage (yellow cherry is less visible and easier to over-ripen). Associated with premium Brazilian specialty lots.

Mundo Novo¶

A natural Bourbon × Typica hybrid from São Paulo, Brazil (discovered 1943, released 1952). Tall, vigorous, high-yielding. Important commercially in Brazil and as a parent of Catuaí. See Mundo Novo.

SL28 and SL34¶

Scott Laboratories selections (Kenya, 1930s–40s) from drought-resistant varieties; SL28 from a Tanganyika drought-resistant variety, SL34 from a French Mission/Bourbon-derived tree. Both express the vivid blackcurrant and red-berry Kenyan cup character associated with high-altitude Bourbon-lineage cultivation. The benchmark for Kenyan specialty quality. SL28 is considered Bourbon-lineage; SL34 is more clearly Bourbon-derived.

Heirloom Bourbon (Réunion Bourbon)¶

Pure Bourbon plants repatriated to Réunion (and to Japan by Ueshima Coffee Company/UCC in the 2000s) for cultivation. Extremely rare; represents the closest genetic approximation to the original island population.

Bourbon Cup Quality Signature¶

Bourbon-lineage varieties at appropriate altitude produce: - Bright, complex acidity — citrus, stone fruit, red berry, malic acid character - High sweetness — characteristically pronounced; caramel, brown sugar - Medium to full body — rounder and more generous than Typica - Fruit-forward flavour: Peach, plum, apple, cherry, raspberry (variety and altitude dependent) - Floral notes — jasmine, rose (particularly at high altitude in East Africa)

This profile makes Bourbon-lineage coffees the benchmark for many specialty buyers seeking expressive fruit-forward cups. The Bourbon lineage is disproportionately represented in Cup of Excellence competition winners across Latin America and East Africa.

Compact Mutation Varieties¶

Three compact Bourbon mutations have been independently identified in different countries:

Variety	Country	Discovery Year
Caturra	Brazil	1915–1935
Pacas	El Salvador	1949
Villa Sarchi	Costa Rica	1950s

All three are believed to be the same or equivalent single recessive gene controlling internode length. All produce compact plants with higher planting density potential and cup quality closely aligned with their Bourbon parent.

Disease Resistance Hybrids from Bourbon Lineage¶

Bourbon-lineage varieties (particularly compact types) have been crossed with the Timor Hybrid to produce disease-resistant hybrids:

Catimor = Caturra × Timor Hybrid
Sarchimor = Villa Sarchi × Timor Hybrid

These crosses retain the compact plant form from the Bourbon-lineage parent and leaf rust resistance from the Timor Hybrid, but carry C. canephora genetic background that can express off-notes in the cup at lower altitudes.

Key Facts¶

Bourbon is a distinct Yemeni Arabica lineage introduced to Réunion c.1715–1718; diverged from Typica during 100 years of island isolation before re-introduction to East Africa and the Americas
Key Bourbon family varieties: Bourbon, Caturra, Catuaí, Mundo Novo, Pacas, Villa Sarchi, Yellow Bourbon, SL28, SL34
Cup quality signature: bright complex acidity, high sweetness, fruit-forward flavour; benchmark for specialty quality in East Africa and Latin America
Three independent compact Bourbon mutations (Caturra, Pacas, Villa Sarchi) produced high-density compact varieties in Brazil, El Salvador, and Costa Rica
Compact Bourbon varieties used as parents in disease-resistant hybrids: Catimor (Caturra × Timor Hybrid), Sarchimor (Villa Sarchi × Timor Hybrid)
