Pacas is a natural mutation of Bourbon, discovered in El Salvador in 1949. It is a dwarf variety known for its compact growth habit, good cup quality, and high productivity. Pacas is widely planted in El Salvador and is a parent of the Pacamara hybrid.

Origin

Discovered on the Pacas family farm in El Salvador in 1949. Natural mutation of Bourbon.

History

Pacas was discovered in 1949 on the Pacas family farm in El Salvador. It is a natural mutation of Bourbon, characterized by its dwarf growth habit (similar to Caturra). The Pacas family noticed the compact trees and selected them for propagation. Pacas was officially released as a variety in 1960 and became widely planted in El Salvador due to its compact size (allowing high-density planting), good cup quality, and high productivity. Pacas is also a parent of the Pacamara hybrid (crossed with Maragogipe).

Discovery

Discovered on the Pacas family farm in El Salvador in 1949.

Genetics and Lineage

Pacas is a natural mutation of Bourbon, belonging to the Bourbon genetic group. The mutation affects growth habit, producing a dwarf plant. Pacas is genetically similar to Caturra, another Bourbon dwarf mutation.

Parent Varieties

Bourbon

Hybrid Status: Not a hybrid. Pacas is a natural mutation of Bourbon. It is a parent of the Pacamara hybrid (crossed with Maragogipe).

Growth Characteristics

Pacas is a dwarf tree with compact growth habit, similar to Caturra. It has short internodes, allowing high-density planting. The tree produces red cherries.

Tree Size: Dwarf (1.5 to 2.5 meters at maturity)

Yield: High. Pacas's compact size allows high-density planting, making it productive per hectare. It yields more than Bourbon.

Disease Resistance: Low. Like Bourbon, Pacas is susceptible to coffee leaf rust and most major pests.

Climate and Growing Conditions

Pacas thrives in Central American highland conditions at elevations of 800 to 1,600 meters. It requires well-distributed rainfall and fertile, well-drained volcanic soils.

Climate Preferences: Tropical highland climate. Optimal temperatures 16 to 26 degrees Celsius.

Rainfall: 1,500 to 2,000mm annually, well-distributed.

Elevation Range: 800-1,600 meters

Processing Compatibility

Pacas is excellent with all processing methods. Washed processing highlights its clean acidity; natural processing enhances sweetness and body.

Roasting Behavior

Pacas beans roast evenly. Light to medium roasts best preserve its sweetness and complexity.

Cup Profile

Pacas has a sweet, balanced cup with bright acidity, medium body, and notes of chocolate, caramel, citrus, and stone fruit. The cup is clean and elegant,...

Acidity

Bright and clean.

Sweetness

High, with caramel and chocolate sweetness.

Body

Medium, smooth.

Professional Cupping Notes

Pacas lots can score 84 to 88 points in SCA cupping. It is valued for its sweetness and balance.

Common Defects

  • •Susceptible to coffee leaf rust

Brewing Recommendations

Pacas excels as pour over and filtered coffee. Recommended brewing temperature: 90 to 95 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.

Varietals & Cultivars

Pacamara Coffee Variety

Pacamara is an El Salvadoran cross between Pacas and Maragogype known for its large bean size and extraordinary complex, savory-sweet cup profile.
