Pacas

The Pacas variety represents a pivotal moment in the history of Salvadoran coffee, originating as a natural mutation of the Bourbon variety. It was first identified in 1949 on a farm owned by the Pacas family in the Santa Ana region of El Salvador. This discovery was significant because the plant exhibited a single-gene mutation that resulted in a dwarf or compact growth habit, a trait that distinguishes it from the taller, traditional Bourbon plants from which it descended. Following its discovery, the Salvadoran Institute for Coffee Research (ISIC) initiated a program of pedigree selection in 1960 to stabilize and refine the variety for commercial cultivation.

In terms of agronomy, the Pacas variety is categorized as a dwarf or compact plant. This physical characteristic is highly valued by farmers because it allows for higher planting densities compared to traditional, taller varieties, potentially increasing the yield per hectare. However, the variety is not without its challenges. It is documented as having a very high susceptibility to coffee leaf rust, a fungal disease that remains a major threat to coffee production globally. This vulnerability requires careful management and often necessitates robust agricultural practices to maintain plant health and productivity.

For the coffee industry, the legacy of Pacas is perhaps most famously tied to the creation of the Pacamara hybrid. In 1958, researchers at the ISIC crossed the Pacas variety with the Maragogype variety—a plant known for its exceptionally large bean size. The resulting hybrid, Pacamara, was designed to combine the desirable cup quality and compact stature of the Pacas parent with the impressive bean size of the Maragogype. This intentional breeding program successfully produced a variety that has become a staple in the specialty coffee market, prized for its unique sensory profile.

From a roaster's and consumer's perspective, Pacas is often appreciated for inheriting the classic, high-quality flavor characteristics associated with its Bourbon lineage. Because it is a direct mutation of Bourbon, it retains much of the sweetness and complexity that the parent variety is famous for. When grown at appropriate altitudes, Pacas can produce a cup that is highly regarded for its balance and clarity, making it a reliable choice for quality-focused producers in El Salvador and beyond.

Understanding the distinction between Pacas and its hybrid offspring is essential for those navigating the specialty coffee landscape. While Pacas is a natural mutation that occurred spontaneously, Pacamara is an artificial hybrid that required human intervention to achieve its specific traits. Both varieties are deeply rooted in the history of the Salvadoran coffee sector, reflecting the country's long-standing commitment to agricultural research and the development of varieties that balance productivity with cup quality.

Today, the state of knowledge regarding Pacas is well-documented through resources like the World Coffee Research Variety Catalog. It remains a standard variety in Central America, serving as both a commercial crop in its own right and a genetic building block for future innovation. As the industry continues to face challenges from climate change and disease, the genetic history of varieties like Pacas provides a foundation for ongoing efforts to develop resilient, high-quality coffee plants that can sustain the livelihoods of farmers while meeting the demands of the global specialty market.
