The Two Species
Coffea arabica accounts for roughly 60 % of global production. It thrives at high altitudes (900–2 000 m), has lower caffeine, and produces complex, nuanced flavours. Coffea canephora (robusta) grows at lower elevations, contains nearly twice the caffeine, and delivers the punch behind classic Italian espresso blends.
Major Growing Regions
| Region | Country examples | Flavour notes |
|---|---|---|
| East Africa | Ethiopia, Kenya, Rwanda | Bright acidity, blueberry, jasmine, citrus |
| Central America | Guatemala, Costa Rica, Honduras | Caramel, hazelnut, mild sweetness |
| South America | Brazil, Colombia, Peru | Chocolate, nutty, low acidity |
| Southeast Asia | Indonesia, Vietnam, Yemen | Earthy, full body, syrupy |
| Caribbean / Pacific | Jamaica, Hawaii, Papua New Guinea | Mild, clean, floral |
From Cherry to Green Bean
Coffee grows as a fruit — the cherry — and the processing method used to remove the pulp profoundly shapes the final flavour:
- Washed (wet): Pulp removed before drying. Clean, bright, expressive acidity.
- Natural (dry): Whole cherry dried in the sun. Fruity, wine-like, complex.
- Honey: Partial pulp left on during drying. Sweet, balanced, between the two.
Ethiopia — The Birthplace
The Kaffa region of southwest Ethiopia is widely considered the genetic homeland of Coffea arabica. Wild coffee trees still grow in forest understorey there, and smallholder farmers have cultivated hundreds of landrace varieties for centuries. Ethiopian coffees — especially those from Yirgacheffe, Sidamo, and Harrar — remain some of the most sought-after in the world for their extraordinary floral and fruit complexity.
