Some coffee varieties arrive through decades of laboratory crossing. Others simply appear in a field one morning, waiting to be noticed. Pacas belongs firmly to the second group. It is a natural dwarf mutation of Bourbon that a Salvadoran coffee family spotted on their own farm at the tail end of the 1940s, and it went on to become one of the workhorse varieties of El Salvador — compact enough to plant densely, sweet enough to satisfy, and genetically generous enough to become a parent of the country's most famous specialty variety. If you have ever admired a clean, gently fruity Salvadoran cup and wondered what was growing on those volcanic slopes, there is a good chance Pacas was part of the answer.
A Chance Find on Finca San Rafael
The story begins around 1949, on a section of the Pacas family's farm — commonly cited as Finca San Rafael — in the Santa Ana region of western El Salvador. Among rows of ordinary Bourbon trees, the family (the name Fernando Alberto Pacas Figueroa is usually attached to the discovery) noticed plants that grew shorter and more tightly packed than their neighbors, yet carried a healthy load of cherry. Rather than dismiss the oddity, they propagated it. The resulting variety took the family surname, and Pacas entered the record as a distinctly Salvadoran contribution to the coffee world.
What makes the discovery meaningful is that El Salvador was, for much of the twentieth century, one of the most Bourbon-dominated coffee countries on earth. Finding a naturally compact version of the nation's signature variety — one that kept the cup but shrank the plant — was a genuinely useful accident. From around 1960 onward, the Salvadoran Institute for Coffee Research (often shortened to ISIC) worked on pedigree selection to stabilize the variety and make its traits reliable from one generation of seed to the next.
What a Single-Gene Mutation Actually Does
Pacas owes its whole identity to one small genetic change. It carries a single-gene mutation for dwarfism — the same broad phenomenon that gives coffee its family of "compact" Bourbon derivatives. Instead of stretching tall with long gaps between branch nodes, a Pacas tree keeps its internodes short. The branches sit closer together, the canopy stays low and dense, and the whole plant occupies less vertical space.
This is not a quirk unique to Pacas. The very same story plays out with Caturra, the compact Bourbon mutation that surfaced in Brazil, and with Villa Sarchi, its Costa Rican counterpart. Each is essentially a shrunken Bourbon born from a comparable single-gene shift, and each was embraced for the same practical reason: a shorter tree is easier to pick and can be planted more tightly. Understanding Pacas really means understanding the broader lineage of Bourbon and the compact offshoots it keeps producing.
How Pacas Compares to Its Bourbon Relatives
Because Pacas sits inside a small club of compact Bourbon mutations, the clearest way to place it is side by side with its cousins and its parent. The table below sketches the broad tendencies rather than fixed rules — terroir, altitude, and processing move every one of these varieties around in the cup.
| Variety | Origin | Relationship to Bourbon | Plant stature | Typical cup character |
|---|---|---|---|---|
| Bourbon | Reunion, then worldwide | The parent variety | Tall | Sweet, balanced, rounded |
| Pacas | El Salvador (c. 1949) | Single-gene dwarf mutation | Compact | Sweet, clean, good body |
| Caturra | Brazil | Single-gene dwarf mutation | Compact | Bright, lively, lighter body |
| Villa Sarchi | Costa Rica | Single-gene dwarf mutation | Very compact | Sweet, structured, high-toned |
The pattern is easy to read: three regions, three separate mutations, one shared instinct to keep the sweetness of Bourbon while taming the plant. Pacas is El Salvador's entry in that lineage, and it holds its own.
Why El Salvador's Volcanic Highlands Suit It
Pacas did not just survive in El Salvador; it thrived there because the country's growing conditions play to its strengths. Much of the nation's coffee grows on volcanic slopes, with a great deal of the finest production concentrated along the Apaneca-Ilamatepec mountain range and around Santa Ana. Volcanic soils tend to be well drained and mineral-rich, and the elevation gives the cool nights that slow cherry maturation and build sweetness and acidity.
A compact tree is well matched to this terrain. Because Pacas stays short and dense, growers can plant more trees per hectare and make efficient use of steep, terraced ground where every square meter counts. It is a variety that rewards the very landscape it was found in, which is one reason it became so deeply woven into Salvadoran coffee that it is often estimated to account for around a quarter of the country's total production.
In the Cup: Sweetness Without the Sprawl
The whole appeal of a Bourbon mutation is that the genetic change alters the plant far more than it alters the flavor. Pacas is generally described as tasting much like Bourbon itself — clean, sweet, and well rounded, often with a pleasing body and a comfortable, approachable profile rather than the wild, high-toned fireworks of some exotic varieties. Tasting notes commonly reach for caramel and gentle stone-fruit or citrus impressions when the coffee is grown at altitude and carefully processed.
It helps to set expectations honestly. Pacas is prized less for showstopping complexity than for dependability: a variety that gives a warm, balanced, satisfying cup with good sweetness and clarity. Grown well on volcanic ground and taken through a clean washed process, it can be quietly excellent — the kind of coffee that makes a strong everyday cup and can still climb into specialty territory when the farm and the mill do their part.
The Parent of Pacamara
Pacas has one more claim to fame beyond its own cup: it is a parent of Pacamara, arguably El Salvador's most celebrated specialty variety. Beginning around 1958, ISIC set out to cross the compact Salvadoran Pacas with Maragogipe, the famously oversized "elephant bean" mutation. The goal was to marry the huge bean size and visual drama of Maragogipe with the yield and cup potential of Pacas.
The name says it all — Pa-ca-mara — and so does the plant. Pacamara inherits the dwarf, compact stature of its Pacas parent, which keeps the tree short and manageable, while carrying the enormous seeds of Maragogipe. Decades of selection followed before the variety was released to producers, but the result became a signature of El Salvador's specialty scene, known for herbal, floral, and high-toned cups when grown well at elevation. None of it would exist without the humble compact tree the Pacas family noticed on their farm.
Growing and Harvesting Pacas
From an agronomic standpoint, Pacas behaves much like the other compact Bourbon mutations, and growers value it for practical reasons. Its traits are worth spelling out:
- Compact, dense canopy from short internodal spacing, which supports higher-density planting and can lift potential yield per hectare.
- Easier picking because a shorter tree keeps cherry within comfortable reach, useful on steep terrain.
- Medium bean size, broadly comparable to Caturra and smaller than large-seeded varieties, giving even, familiar green coffee.
- Standard disease susceptibility for a traditional Bourbon-type variety, meaning it offers little natural resistance to coffee leaf rust and depends on good farm management.
Like most classic Central American varieties, Pacas is typically taken through washed processing to preserve its clean sweetness, though producers increasingly experiment with natural and other methods to add fruit-forward layers. Because it is a stable, long-selected variety rather than a modern hybrid, seed comes true reliably from one generation to the next — a quiet advantage for farmers replanting from their own trees.
Pacas Beyond El Salvador
Although Pacas is unmistakably a Salvadoran variety by birth, it did not stay put. It spread most notably into Honduras, where the national coffee institute, IHCAFE, is generally credited with introducing it in the 1970s, and it turns up elsewhere in Central America as growers look for productive, cup-worthy Bourbon types. Its footprint is still centered on El Salvador and its immediate neighbors rather than the wider coffee world, which keeps a certain regional character attached to the name.
That regional identity is part of what makes Pacas worth knowing. It is a reminder that the coffee in your cup is shaped not only by grand breeding programs but by observant farmers who paid attention to an odd little tree in the corner of a field. Few varieties carry a family name; fewer still went on to father a specialty legend. Pacas managed both, quietly, from a single Salvadoran hillside.
Frequently Asked Questions
What is the Pacas coffee variety?
Pacas is a natural dwarf mutation of the Bourbon variety, discovered around 1949 on the Pacas family's farm in the Santa Ana region of El Salvador. The single-gene mutation makes the plant compact while keeping much of Bourbon's sweet, balanced cup quality.
How is Pacas different from Bourbon?
Genetically they are almost the same; the difference is mostly in the plant. Pacas carries a dwarfism mutation that gives it short internodes and a compact, dense canopy, so it can be planted more tightly and picked more easily. In the cup it tastes very similar to Bourbon — clean, sweet, and well rounded.
Is Pacas related to Caturra and Villa Sarchi?
Yes, in the sense that all three are compact single-gene mutations of Bourbon that appeared naturally in different countries — Pacas in El Salvador, Caturra in Brazil, and Villa Sarchi in Costa Rica. They share the same basic story of a shorter, denser Bourbon tree, though each was found and selected separately.
What does Pacas coffee taste like?
Pacas is generally described as clean, sweet, and balanced with a pleasant body, often showing caramel sweetness and gentle stone-fruit or citrus notes when grown at altitude on volcanic soil and carefully processed. It is prized more for dependable, satisfying quality than for extreme complexity.
Why is Pacas important to Pacamara?
Pacamara was created by crossing Pacas with the large-beaned Maragogipe variety, a breeding project the Salvadoran coffee institute began around 1958. Pacamara inherits its short, compact stature from the Pacas parent while carrying Maragogipe's oversized beans, making Pacas an essential ancestor of one of El Salvador's most celebrated specialty varieties.
