Arabica
Erecta
Also known as: Erecta (Bourbon)
Erecta is a prominent variety of Coffea canephora (Robusta) native to Uganda. Characterized by its tall, upright growth habit and slender beans, it offers a bold, full-bodied cup with distinct bitterness and higher acidity. It is a staple of Ugandan coffee production, often used in espresso blends for its strong finish and resilience.
Key Takeaways
- Erecta is one of the two indigenous Robusta varieties central to Uganda's coffee industry, alongside Nganda.
- The variety is named for its 'erect' or upright growth habit, featuring branches that point toward the sky at a 25-degree angle.
- It offers a distinct cup profile characterized by bold bitterness, high body, and a surprising level of acidity for a Robusta variety.
- Erecta is highly resilient to common coffee pests and diseases, serving as a vital genetic resource for global coffee breeding.

Erecta is a natural mutation of Bourbon, characterized by its upright (erect) growth habit, in contrast to the typical spreading habit of Bourbon. It is a lesser-known mutation that is primarily of botanical and breeding interest.
Origin
Natural mutation of Bourbon.
History
Erecta was discovered as a natural mutation of Bourbon. The mutation affects growth habit, producing a tree with upright branches rather than the typical spreading habit of Bourbon. Erecta is primarily of botanical and breeding interest and is not widely planted commercially. It is maintained in research collections.
Discovery
Discovered as a natural mutation of Bourbon.
Genetics and Lineage
Erecta is a natural mutation of Bourbon, belonging to the Bourbon genetic group. The mutation affects growth habit.
Parent Varieties
Hybrid Status: Not a hybrid. Erecta is a natural mutation of Bourbon.
Growth Characteristics
Erecta is a tall tree with upright branches, unlike the spreading habit of typical Bourbon.
Tree Size: Tall (3 to 4 meters at maturity)
Yield: Moderate.
Disease Resistance: Low. Like Bourbon, Erecta is susceptible to coffee leaf rust.
Climate and Growing Conditions
Similar to Bourbon, thrives in tropical highland conditions at elevations of 1,000 to 1,800 meters.
Climate Preferences: Tropical highland climate.
Rainfall: 1,500 to 2,000mm annually.
Elevation Range: 1,000-1,800 meters

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.
ArabicaBourbon
Sweet, complex, and balanced. Known for a pronounced sweetness, deep fruit notes (berry, stone fruit), and bright but rounded acidity. Body is medium to full with a smooth, creamy mouthfeel. Among the most sought-after cup profiles in specialty coffee.
ArabicaCaturra
Bright, clean, and sweet. Known for pronounced citric acidity, medium body, and notes of citrus, stone fruit, and caramel. Generally produces a more straightforward but vibrant cup than its parent Bourbon, with slightly less complexity but excellent clarity.

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.
Coffee ScienceCoffee Leaf Rust
Hemileia vastatrix belongs to the order Pucciniales and is an obligate biotrophic fungus, meaning it requires living host tissue to survive. The infection cycle begins when urediniospores are deposited on the abaxial (underside) surface of the coffee leaf, typically via wind or rain splash. Germination occurs only in the presence of free water—such as dew or rainfall—within a temperature range of 15°C to 28°C. Upon germination, the fungus enters the leaf through the stomata and establishes a mycelium that colonizes the internal tissue. The visual manifestation of the disease begins as small, chlorotic spots that expand into characteristic orange, powdery pustules. These pustules contain thousands of spores capable of further infection. The physiological impact includes a rapid reduction in photosynthetic capacity and the eventual abscission of the leaf. Severe cases lead to 'dieback,' where the plant's branches wither due to carbohydrate depletion, often resulting in the death of the tree or a total loss of the following year's crop.
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.
