Origin
Sidikalang area, Dairi regency, North Sumatra, Indonesia. Typica-related, introduced during Dutch colonial era.
History
Sidikalang is named after the Sidikalang area in the Dairi regency of North Sumatra, Indonesia. The variety was introduced during the Dutch colonial era and is believed to be Typica-related. It has been cultivated in the highland areas of North Sumatra for over a century. Sidikalang is processed using the traditional Sumatran wet-hulling method (giling basah), which contributes to the distinctive cup profile of Sumatran coffee.
Discovery
Introduced to North Sumatra during the Dutch colonial era.
Genetics and Lineage
Sidikalang is a Typica-related variety, belonging to the Typica genetic group. It has been adapted to the highland conditions of North Sumatra over more than a century of cultivation.
Parent Varieties
Hybrid Status: Not a hybrid. Sidikalang is a Typica selection adapted to North Sumatra.
Growth Characteristics
Sidikalang is a tall tree with bronze-tipped young leaves, typical of Typica varieties.
Tree Size: Tall (3 to 4 meters at maturity)
Yield: Moderate. Sidikalang yields less than modern varieties but is valued for its contribution to Sumatran coffee character.
Disease Resistance: Low. Like Typica, Sidikalang is susceptible to coffee leaf rust.
Climate and Growing Conditions
Sidikalang thrives in the highland conditions of North Sumatra at elevations of 1,200 to 1,600 meters. It requires shade and consistent rainfall.
Climate Preferences: Tropical highland, equatorial climate. Optimal temperatures 16 to 24 degrees Celsius.
Rainfall: 2,000 to 3,000mm annually (high rainfall, equatorial).
Elevation Range: 1,200-1,600 meters
Processing Compatibility
Sidikalang is traditionally processed using the wet-hulling method (giling basah), which is unique to Indonesia and produces the distinctive Sumatran cup profile. Washed and natural processing are less common but possible.
Roasting Behavior
Sidikalang beans are medium density. Medium to dark roasts are traditional and bring out the earthy, spicy character of Sumatran coffee.
Cup Profile
Sidikalang produces a full-bodied, low-acidity cup characteristic of Sumatran coffee. It has notes of earth, cedar, spice, chocolate, and sometimes tobacco or leather. The wet-hulling process contributes to the unique, earthy character.
Professional Cupping Notes
Sidikalang lots typically score 82 to 86 points in SCA cupping, valued for their body and uniqueness rather than clarity.
Common Defects
- •Susceptible to coffee leaf rust
- •Wet-hulling can produce earthy or musty defects if not done properly
Brewing Recommendations
Sidikalang works well as espresso, French press, and filtered coffee. Recommended brewing temperature: 92 to 96 degrees Celsius.

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.

Acidity
In coffee tasting, acidity refers to the bright, vibrant, and often fruity quality that gives coffee its liveliness and structure. Unlike the negative connotation of acidity in everyday language, coffee acidity is a desirable characteristic when balanced. It is perceived as a pleasant tartness or brightness on the palate, similar to the acidity in wine or fruit.
Origins & GeographyCoffea 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 ScienceDefects
Coffee defects are imperfections in green or roasted coffee beans that negatively affect flavor, aroma, or appearance. The SCA Green Coffee Classification limits defects in specialty-grade coffee to a maximum of 5 full defects per 300g.
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.
