Varieties & genetics

What is the Pacamara variety?

Pacamara is a hybrid arabica variety created in El Salvador in 1958 by the ISIC (Instituto Salvadoreño de Investigaciones del Café), resulting from the cross between Pacas (a dwarf Bourbon mutation) and Maragogype (a giant Typica mutation). It is prized for its very large beans, exceptional aromatic complexity potential, and relative rarity on the world market.

Pacamara is the result of an intentional breeding programme aimed at combining Pacas's compact productivity with Maragogype's exceptional bean size — whose beans can exceed 9 mm in length, roughly twice the size of a standard arabica bean (4-5 mm). This extraordinary size directly impacts the roast profile: Pacamara beans require slower heat curves and longer development times to ensure even heat penetration to the bean's core.

Sensorially, Pacamara is often described as one of the most complex arabica varieties available. Its typical profiles include fresh grass and vegetal notes at the attack (altitude character), followed by tropical fruits or citrus in the mid-palate, and a long chocolaty finish with occasional floral undertones. This multi-layer evolution is attributed to high concentrations of aroma precursors — sugars, amino acids, and organic acids — that the large bean size allows to accumulate during ripening.

Pacamara is grown primarily in El Salvador, Nicaragua, Guatemala, and Honduras. In El Salvador it has become an emblematic variety: several Pacamara micro-lots have won awards at the Cup of Excellence. Its susceptibility to coffee leaf rust (Hemileia vastatrix) is a notable drawback — though the high-altitude plantations enabling its maximum aromatic expression are also zones where rust is less aggressive, providing a workable compromise. A remarkable fact: Pacamara is genetically unstable and can show very different phenotypes from plant to plant within the same plot, which makes authenticated Pacamara micro-lots particularly rare and valuable.

Pacamara: El Salvador's Outsized Contribution to Specialty Coffee

El Salvador occupies a modest place in the coffee world by volume — it's not Ethiopia, Brazil, or Colombia — but it has produced one of the most distinctive and celebrated varieties in specialty history: Pacamara. Developed in 1958 at El Salvador's Institute for Coffee Research by crossing Pacas (a Bourbon natural mutation) with Maragogype (a Typica natural mutation famous for its enormous bean size), Pacamara inherited the giant bean size of its Maragogype parent and the vigorous, compact growth habit of Pacas. The resulting bean is so large that it barely fits in a standard coffee portafilter without grinding adjustments, and its visual drama in the green form — beans up to twice the size of standard Arabica — made it a natural conversation piece even before its cup quality was fully understood.

The cup profile of Pacamara is as dramatic as its physical presence. At its best — washed, high-altitude, from El Salvador's Santa Ana or Ahuachapán regions — it produces an intensely aromatic cup with distinct vegetative-herbal notes that are unusual in coffee, sometimes described as green pepper or bell pepper alongside more familiar fruit and chocolate characteristics. This vegetative quality, which comes from pyrazine compounds present in the variety, divides tasters: those trained on fruit-forward or chocolate profiles may find it disconcerting, while those who encounter it as a distinctive characteristic learn to seek it out as an identifier of Pacamara's authentic expression. World Barista Championship competitors have featured Pacamara from El Salvador multiple times in the past decade, introducing the variety to global audiences through competition's educational platform.

Practical Recommendations

Finding good Pacamara requires intentional sourcing. El Salvador's specialty production is small and the variety is grown in limited quantities even within the country. Specialty importers who work directly with Salvadoran farms are your most reliable route; look for washed processing and altitude declarations above 1,400 meters. At home, brew Pacamara slightly coarser than you would a standard Arabica — the large bean size means extraction dynamics differ from smaller-bean varieties, and slightly faster flow rate through a pour-over produces better balance. Note the vegetative-herbal characteristic explicitly when you taste it: if you can identify it clearly, you've developed a useful variety-specific marker that will help you recognize Pacamara in future blind tastings.
