Pacas is a Bourbon-derived Arabica coffee variety characterized by its compact plant structure, balanced cup profile, and role in Central American coffee breeding. 

In this guide, you’ll learn where Pacas came from, what makes its plant structure distinctive, how it tends to taste, and how to brew it well. This guide also covers its most well-known descendant, Pacamara. 

 

The Origin of Pacas Coffee

Pacas is a natural mutation of Bourbon, first identified in 1949 on a farm belonging to the Pacas family in Santa Ana, El Salvador.

Because it originated as a natural mutation, early populations showed variation in plant appearance, yield, flavor, and disease resistance—making systematic selection necessary to stabilize the genetics.

According to the World Coffee Research (WCR), the Instituto Salvadoreño de Investigaciones del Café (ISIC) launched a formal selection program in 1960. By tracking superior mother plants and their offspring, researchers identified stable, high-quality lines.

Today, Pacas is one of El Salvador’s most widely planted coffee varieties and is also grown in Honduras and other parts of Central America. 

 

Pacas Coffee Plant Characteristics

Pacas is notably compact. Its shorter stature—compared to traditional Bourbon lines—allows for higher planting density, which can translate to greater yield per unit of land when well managed. For small farms in particular, the lower canopy also makes harvesting more accessible and reduces the physical risks that come with working at height.

Altitude & Flavor Development

Beyond yield, Pacas has good flavor potential, though its lower disease resistance makes it better suited to higher-altitude growing areas where pest and disease pressure is generally reduced. At elevation, cooler temperatures slow cherry maturation, allowing more time for flavor compounds to develop—often resulting in greater complexity and layered character in the cup.

Agronomic Traits 

The following plant data is based on World Coffee Research (WCR) specifications:

• Plant stature: Dwarf / suitable for dense planting
• Leaf tip color: Green
• Bean size: Medium
• Yield: Moderate
• Quality potential at high altitude: Good

Recommended growing altitude

• Latitude 5°N–5°S: best above 1,600 m
• Latitude 5–15°N or 5–15°S: best above 1,300 m
• Latitude >15°S or >15°N: best above 1,000 m

Disease Resistance

• Coffee leaf rust: Low resistance
• Nematodes: Susceptible
• Coffee berry disease (CBD): Susceptible

Pacas Coffee Flavor Profile

The flavor of Pacas is shaped by origin, altitude, processing, and roast level. In general, its cup profile is considered close to Bourbon—balanced and sweet, with a few common characteristics:

• Acidity: Typically soft to bright fruit acidity; some lots may show citrus or other fruit tones. At higher altitudes, slower maturation can produce more defined acidity.
• Sweetness: Often caramel- or honey-like, complementing the acidity for a balanced overall impression.
• Mouthfeel: Round and smooth, with moderate body. The structure leans balanced rather than intense.
• Finish: Depending on the lot, the finish may carry light nutty, cocoa, or floral hints—generally clean and gentle.

3 Key Challenges of Growing Pacas

While Pacas has clear advantages in plant size, yield, and flavor, producing high-quality lots is not straightforward. Here are three common difficulties growers face:

1. Low Disease Resistance

Pacas is vulnerable to coffee leaf rust, nematodes, and coffee berry disease. Without close monitoring and active management, disease pressure can reduce yields, and in serious cases, affect the health of the plant itself. Growing Pacas typically demands more detailed pest and disease control than more resistant varieties.

2. Environmental Requirements

Pacas tends to express its best quality at higher altitudes, and many producers plant it above 1,000 m. In recent years, rising temperatures from climate change have pushed some farmers to adjust planting elevation or seek out different microclimates to maintain suitable growing conditions.

3. Management Intensity

The ability to plant Pacas densely is both an advantage and a challenge. More plants per area means each one is competing for soil nutrients and moisture—requiring careful fertilization and soil management to keep the planting healthy.

Dense canopy growth can also restrict airflow and light penetration, raising humidity levels and increasing the risk of certain pests and diseases. In practice, growers typically manage this through regular pruning and canopy shaping to maintain good air circulation and light exposure.

 

Pour-Over Parameters for Pacas

Pour-over is a common way to highlight Pacas gentle, soft acidity and sweetness. Adjusting grind size, water temperature, and brew ratio allows for more precise control over how clearly those flavors come through.

If you’re newer to pour-over and still building your flavor preferences, the parameters below are a reasonable starting point:

• Brew ratio: 1:15–1:17
• Grind size: Medium-fine to medium-coarse. If your brew tastes too bitter, grind slightly coarser; if it tastes too sour, grind slightly finer.
• Water temperature: Light roast ~90–94°C (194–201°F); dark roast ~88–92°C (190–198°F)
• Brew time: Approximately 2–3 minutes

Pacas’ Offspring: Pacamara

When discussing Pacas, its standout offspring—Pacamara—deserves its own mention.

Pacamara was developed by crossing Pacas with Maragogipe. Yield is relatively low and disease resistance is limited, but the beans are notably large—typically screening at 17+ mesh, compared to the 14–16 mesh common in most Arabica varieties.

Under the right growing conditions and processing, Pacamara frequently shows bright fruit acidity and good sweetness, with flavor notes that can include citrus, tropical fruit, florals, and chocolate.

Its distinctiveness and expressive flavor have made it a frequent contender in Cup of Excellence (COE) competitions, drawing interest from specialty producers and roasters worldwide.

Pacamara also comes in two color variants:

• Yellow Pacamara: A natural mutation of the red version. Flavor tends toward tropical fruit aromatics, with a harmonious sweetness and softer mouthfeel.
• Red Pacamara: More pronounced sweetness with a fuller, richer mouthfeel.

Frequently Asked Questions about Pacas

What are Pacas’ market advantages?

The advantages play out differently for farmers and consumers.

For farmers, the compact plant structure allows improved land-use efficiency, while the lower canopy makes harvesting easier and safer. In parts of Central America, Pacas continues to be planted widely because of its stable yields and reliable cup quality.

For consumers, Pacas is generally known for a balanced, sweet, and approachable profile, and because it’s a well-established variety with stable supply, pricing tends to be accessible.

What brewing methods suit Pacas?

Pacas is particularly well suited for pour-over brewing, where variables such as grind size, brew ratio, water temperature, and pouring technique can be adjusted to highlight its soft acidity and sweetness.

If you prefer a richer flavor profile, heavier body, and dense crema, Pacas also performs well as a single-origin espresso (SOE), producing a cup with relatively mild acidity and concentrated sweetness. For those who enjoy a lighter body with more aromatic clarity and layered fragrance, siphon brewing is another excellent option.

 

A High-Stability Hand Grinder for Pacas Flavor Expression

Bringing out Pacas’ balanced character depends not just on bean quality—consistent grinding plays an equally important role.

Consistent particle size is important for Pacas brewing, as it helps preserve clarity and balance in the cup. A grinder with stable mechanics can improve consistency across extractions. 

1Zpresso hand grinders use a high-stability structural design that minimizes movement during grinding, producing more uniform particle size and more consistent extraction. In practice, that stability translates directly into a more repeatable cup—a quality valued by coffee professionals. 

For a grinder that handles both pour-over and espresso, the K-Ultra is worth considering:

• Efficient grinding: A heptagonal conical burr set helps ensure consistent grinding performance with high precision and uniformity of particle size.
• Multi-Step grind adjustment: Over 100 grind settings, and enough precision to emphasize Pacas fruit acidity or pull sweetness forward, depending on what you’re after.
• Tool-free disassembly: The full grinder breaks down without tools, making cleaning easier and helping ensure that residual grounds don’t interfere with flavor clarity between sessions.
