Origin
Southern Mozambique and South Africa.
History
Coffea racemosa is a wild coffee species native to southern Mozambique and South Africa. It was scientifically described in the 19th century. Racemosa has been used locally but never commercially cultivated at scale. In recent years, racemosa has gained attention for its extreme drought tolerance, low caffeine content, and distinctive flavor. Brazilian agronomist Flavio Borem crossed racemosa with Arabica to create the Aramosa hybrid, which is being explored for climate change adaptation.
Discovery
Scientifically described in the 19th century from specimens found in southern Africa.
Genetics and Lineage
Coffea racemosa is a distinct diploid Coffea species (2n=22), separate from Arabica, Robusta, and Liberica. It is genetically distinct and represents a unique lineage within the Coffea genus.
Parent Varieties
Hybrid Status: Not a hybrid. Racemosa is a distinct Coffea species. It is a parent of the Aramosa hybrid (crossed with Arabica).
Growth Characteristics
Racemosa is a shrub or small tree adapted to hot, dry conditions. It is deciduous, losing its leaves during the dry season. The cherries are small and dark purple.
Tree Size: Shrub to small tree (1.5 to 4 meters)
Yield: Very low. Racemosa is not commercially cultivated at scale.
Disease Resistance: Potentially high. Racemosa is adapted to hot, dry conditions and may be resistant to drought and heat stress.
Climate and Growing Conditions
Racemosa thrives in hot, dry lowland conditions. It is extremely drought-tolerant, surviving in areas with as little as 500mm of rainfall.
Climate Preferences: Hot, dry tropical climate. Can tolerate temperatures above 30 degrees Celsius.
Rainfall: 500 to 1,500mm annually (very drought-tolerant).
Elevation Range: 0-600 meters
Processing Compatibility
Compatible with all processing methods. Natural processing is traditional.
Roasting Behavior
Racemosa beans are small and dense, requiring careful roasting.
Cup Profile
Racemosa produces a unique cup with very low caffeine content (approximately 0.2 to 0.4%). It has notes of jasmine, tropical fruit, honey, and sometimes savory or herbal notes. The cup is unlike any Arabica or Robusta.
Professional Cupping Notes
Racemosa is not commonly cupped in competitions, but its hybrid Aramosa has shown promising results.
Common Defects
- •Very low yield
- •Not commercially established
- •Very small beans
Brewing Recommendations
Racemosa is best brewed as pour over to highlight its unique character.

Arabica Coffee Varieties: Origin, Flavor & Genetics
Arabica is known for its complex, aromatic, and nuanced flavor. It generally has higher acidity, lighter body, and more aromatic complexity than Robusta. Notes range from floral and citrus (highland African) to chocolate and caramel (Central and South American). Sweetness is generally high, with clean, balanced cups being the hallmark of quality Arabica.

LibericaExcelsa
Excelsa has a distinctive tart, fruity, and complex flavor that differs from typical Liberica. It has a medium body, bright (but not citric) acidity, and notes of dark fruit, tamarind, and woody spice. The flavor is unique and often used in small percentages in blends to add complexity.
LibericaLiberica
Liberica is known for its bold, smoky, and distinctive flavor. It has a full, heavy body, low acidity, and notes of smoke, wood, dark chocolate, and tropical fruit. The flavor is polarizing: some find it unique and compelling, while others find it overpowering. In the Philippines, Barako coffee (Liberica) is a cultural icon.
RobustaRobusta Coffee: Flavor, Caffeine & Growing Regions
Bold, strong, and earthy. Known for heavy body, low acidity, and notes of dark chocolate, nuts, and grain. Can exhibit earthy, woody, or rubbery notes in lower-quality lots. Fine Robusta (carefully processed) can produce a cleaner, sweeter cup with chocolate and caramel notes.

Coffea Arabica: The Specialty Coffee Species Explained
Arabica coffee (Coffea arabica) is a species of coffee plant native to the highland forests of Ethiopia and South Sudan. It is the most widely cultivated coffee species worldwide, accounting for approximately 60 to 70 percent of global coffee production. Arabica is prized for its complex flavor, refined acidity, and aromatic diversity, producing notes ranging from floral and citrus to chocolate and caramel depending on origin, variety, and processing.
Origins & GeographyCoffea Robusta: The Hard-Body Coffee Species Explained
Robusta coffee (Coffea canephora) is the second most cultivated coffee species after Arabica, accounting for approximately 30 to 40 percent of global coffee production. Native to sub-Saharan Africa, Robusta is hardier, more disease resistant, and grows at lower elevations than Arabica. It contains roughly twice the caffeine of Arabica and produces a heavier body, lower acidity, and more bitter cup profile.
Coffee ScienceExtraction
Extraction is the process of dissolving soluble compounds from ground coffee into water, producing the beverage we know as coffee. During extraction, water pulls acids, sugars, lipids, carbohydrates, and melanoidins from the coffee grounds in a sequence that shapes flavor, body, and aroma.

Arabica Vs Robusta
Coffea Arabica and Coffea Canephora (Robusta) are the two dominant botanical species of coffee cultivated globally. Arabica is a tetraploid species with 44 chromosomes grown at high altitudes, producing nuanced sugars, delicate fruit acids, and low caffeine. Robusta is a diploid species with 22 chromosomes that contains nearly double the caffeine, double the chlorogenic acids, and exceptional espresso crema density.
