Origin

Developed at the Coffee Research Station, Balehonnur, India, in the 1940s-1950s.

History

S795 was developed in India in the 1940s-1950s by the Coffee Research Station in Balehonnur (now the Central Coffee Research Institute). It is a cross between Kent (a Typica selection from India) and S288 (a natural hybrid between Arabica and Liberica). S795 was developed for resistance to coffee leaf rust and was released in the 1950s. It became one of the most widely planted Arabica varieties in India and was also distributed to Indonesia and other Asian coffee-producing countries. S795 is known locally in India as 'S.795' and in Indonesia as 'Jember.'

Discovery

Developed at the Coffee Research Station in Balehonnur, India, in the 1940s-1950s.

Genetics and Lineage

S795 is a hybrid of Kent (Typica group, Arabica) and S288 (a natural Arabica-Liberica hybrid). It has predominantly Arabica genetics with some Liberica ancestry from S288, which contributes to its disease resistance.

Parent Varieties

Kent (Typica)S288 (Arabica x Liberica natural hybrid)

Hybrid Status: S795 is a hybrid between Kent (Typica) and S288 (Arabica x Liberica). The Liberica ancestry from S288 provides some disease resistance.

Rainfall: 1,200 to 2,000mm annually.

Elevation Range: 800-1,500 meters

Processing Compatibility

S795 is compatible with all processing methods. Washed (wet) processing is traditional in India and Indonesia.

Roasting Behavior

S795 beans are medium density and roast evenly. Medium roasts are typical.

Cup Profile

S795 produces a smooth, balanced cup with low to medium acidity, medium body, and notes of spice, chocolate, nuts, and sometimes caramel. The cup is...

Acidity

Low to medium.

Sweetness

Moderate.

Body

Medium, smooth.

Professional Cupping Notes

S795 lots typically score 82 to 86 points in SCA cupping.

Common Defects

  • •Resistance to coffee leaf rust has diminished with new rust races

Brewing Recommendations

S795 works well as filtered coffee, espresso, and in blends. Recommended brewing temperature: 90 to 96 degrees Celsius.

Sensory & Tasting

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.

Sensory & Tasting

Body

Body, also called mouthfeel, refers to the physical weight, texture, and viscosity of coffee as it is perceived in the mouth. It is a tactile sensation rather than a taste, ranging from thin and tea-like to thick and syrupy. Body is influenced by brewing method, coffee oils, suspended solids, roast level, and the variety and origin of the coffee.

Origins & Geography

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 Science

Coffee 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 Science

Extraction

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.

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.

Varietals & Cultivars

Typica Coffee Variety

Typica is the foundational arabica variety from which nearly all cultivated coffee descends. Originating in Ethiopia and Yemen, then carried to Java and the Americas, its tall trees and elongated cherries produce a clean, sweet, delicately floral cup that defined specialty coffee's earliest standards.

Comparison

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.

Varietals & Cultivars

Hibrido De Timor Coffee

Hibrido de Timor is a natural cross of arabica and robusta discovered on Timor Island. It inherited robusta's disease resistance and arabica's cup quality, making it the foundational parent of most modern disease-resistant varieties including Catimor, Sarchimor, and Ruiru 11.
