El Salvador's New Wave: SL28, Sudan Rume, and the African Varieties Reshaping Its Coffee
El Salvador’s coffee identity has always been Bourbon. The variety accounts for roughly 60% of the country’s production, lending that signature sweetness and chocolate depth the origin is known for. Pacas—a natural Bourbon mutation discovered in 1949 by the family it’s named after—and the impressive Pacamara hybrid round out the lineup that specialty buyers have come to expect.
But a quiet shift is underway on the volcanic slopes of Santa Ana and Usulután. Fifth-generation producers are planting seeds from Kenya and Ethiopia, betting that African genetics can push their farms into the ultra-specialty tier—where lots sell for $50 per pound and above, and Cup of Excellence scores crack 90 points.
SL28 Finds a Second Home
Kenya’s SL28 has become the most established of the imports. Scott Agricultural Laboratories developed the variety in the 1930s, selecting for drought resistance and that unmistakable blackcurrant acidity that makes Kenyan coffee so distinct. Salvadoran producers began experimenting with SL28 around the early 2000s, drawn by the variety’s intense, wine-like profile.
“The challenge with some of these African varieties in El Salvador is the way they adapt to our weather conditions compared to their native countries,” explains Maria Pacas, a fifth-generation producer at Café Pacas in Santa Ana. Her Cup of Excellence-winning farm has been trialling African genetics alongside its heritage Bourbon plots.
SL28 thrives in Kenya’s bimodal rainfall pattern—two distinct wet seasons that produce two harvests. El Salvador’s single harvest runs October through March, and the African varieties ripen early in that window. Late rains can damage cherries before they’re picked. It’s a gamble that requires careful lot management and selective harvesting.
Sudan Rume and the Rare Landrace Revival
Diego Baraona farms Los Pirineos in Usulután, in southeastern El Salvador—another Cup of Excellence winner with five generations of coffee growing behind it. His father obtained Sudan Rume seeds around 2017 and began trials, intrigued by the variety’s origin story.
Sudan Rume is an ancient landrace believed to have first been cultivated on the Boma Plateau in what is now South Sudan. Unlike the manicured cultivars bred for disease resistance and yield, landraces evolved over centuries in their native environments, developing complex flavour compounds that modern varieties often lack. Sudan Rume cups with floral, tea-like characteristics and delicate sweetness—a sharp contrast to Bourbon’s heavier body.
Gesha has also arrived, predictably. Nine Gesha lots appeared at El Salvador’s 2025 Cup of Excellence auction, with two scoring above 90 points. The variety that made Panama famous is now spreading across Central America, and Salvadoran producers see opportunity in the trend.
The Business Case for Exotic Genetics
Growing African varieties at scale isn’t feasible—yields are lower, climate adaptation is uncertain, and the learning curve is steep. But that’s precisely the point. These lots aren’t meant to replace Bourbon production. They’re positioned as ultra-premium micro-lots that can command specialty auction prices.
“You need to have a balance of good quality volume coffees, like 84 and 85-point Bourbons and Pacamaras, and then you can invest in high-end lots,” Baraona explains. The economics work when a farm’s base production supports the experimental gambles.
The cup profiles these varieties produce offer something Salvadoran coffee hasn’t traditionally had: the vibrant, sometimes sharp acidity and pronounced floral notes associated with East African origins. For roasters seeking differentiation, a Salvadoran SL28 or Sudan Rume is an unexpected find—familiar variety names from unfamiliar terroir.
Bernadina’s Secret
One surprise has emerged from genetic testing. Bernadina, long considered a native Salvadoran variety, shares 30% of its DNA with a variety from Ethiopia’s Agaro region. The connection suggests El Salvador’s coffee heritage has deeper African roots than previously understood—a genetic history that modern producers are now deliberately expanding.
Why This Matters
USDA projects El Salvador’s 2025/26 production at 597,000 60-kilo bags, a modest increase from recent years but still a fraction of neighbouring Guatemala or Honduras. Labour shortages and high input costs continue limiting growth. The country can’t compete on volume.
What it can do is compete on quality and story. Bourbon from volcanic slopes at 1,500 metres has always been special. Add Kenya’s SL28 with its blackcurrant punch, Ethiopia’s Gesha with its jasmine perfume, and Sudan Rume with its ancient landrace complexity, and El Salvador’s specialty farms become origin laboratories—testing how African genetics express themselves in Central American terroir.
The results are still emerging. Most African variety plots in El Salvador are young, with limited production. But at next year’s Cup of Excellence, expect to see more than nine Geshas on the table. The African wave is just beginning.
