Eugenioides Coffee

Coffea eugenioides is not a varietal of Arabica, it is one of Arabica’s two wild parents. A 2024 genome study in Nature Genetics dates the natural hybridization of eugenioides and Coffea canephora that produced Coffea arabica to somewhere between 350,000 and 610,000 years ago, and traces Arabica’s chloroplast genome, which plants inherit maternally, directly back to eugenioides. The species grows wild in the highland forests of the eastern Democratic Republic of Congo, Rwanda, Uganda, Kenya, and western Tanzania, where it was never cultivated or consumed on its own: a small, delicate understory tree with sparse, tiny cherries that gave growers little reason to bother with it once Arabica itself existed.

That changed only in the past decade, once the Holguin family’s Finca Inmaculada, in the Pichinde hills outside Cali, Colombia, began propagating pure eugenioides as a specialty crop in its own right, alongside a second, separately documented planting at Finca Perla Negra in Pichincha, Ecuador. Yields are tiny, reportedly a few hundred grams of cherry per tree, which keeps pure eugenioides among the rarest coffees any roaster can offer. Paradise Roasters’ Ecuador Eugenioides Natural scored 94 points from Coffee Review in January 2020, described in the blind assessment as “round, sweet, complex, original,” with magnolia, musk, and lemon verbena in the aroma and a cup carrying maple syrup, peach, and jackfruit through a buoyant, satiny finish. Other roasters working directly with Finca Inmaculada report a similar register: papaya, guava, strawberry yogurt, and a “cereal milk” sweetness, with almost no bitterness in the cup.

The sweetness is not an accident of processing. Eugenioides carries one of the lowest caffeine contents ever measured in the genus Coffea, averaging roughly 0.5% by dry weight in peer-reviewed sampling of wild Kenyan accessions, under half of Arabica’s own roughly 1.2% and a fifth of Robusta’s roughly 2.2%. Caffeine and coffee’s bitter chlorogenic acids track together across wild Coffea species, so a plant this low in one tends to run low in the other too, which is the leading explanation for why eugenioides tastes so sweet with so little bite. That profile won over competition judges fast: at the 2021 World Barista Championship, Diego Campos took first place and Andrea Allen placed second, both building their routines around eugenioides, a jump from obscure botanical curiosity to competition-circuit fixture in a single season.

Roasters tend to treat eugenioides more like a delicate single-origin filter coffee than a blending component: light roasts to protect its natural sugars, and pour-over or similarly gentle brewing to let the floral and fruit notes carry without concentrated, roast-driven bitterness crowding them out. Whether it ever becomes more than a once-a-year novelty lot depends entirely on whether Finca Inmaculada, Finca Perla Negra, or another grower can meaningfully improve on cherry counts this small.
