Pink Bourbon

Pink Bourbon is a Colombian coffee variety with salmon-pink cherries, an outsized competition record, and a name that recent genetic work suggests is wrong. It is one of the most sought-after varieties in specialty coffee and one of the least settled: the evidence now points away from any relationship to Bourbon and toward an Ethiopian landrace that arrived in Colombia by an unrecorded route.

Is Pink Bourbon Actually a Bourbon?

Almost certainly not. For years the standard explanation was that Pink Bourbon was a spontaneous cross between Red and Yellow Bourbon, producing an intermediate cherry colour. It was a tidy story, it matched what growers saw in the field, and it turned out not to survive testing.

Two rounds of commercial DNA fingerprinting have now been reported:

• In 2017, leaf material from two morphologically different Pink Bourbon plants, one tall and one short, was analysed by the laboratory DNA Analytica on behalf of a green coffee importer. Both profiles resembled wild Ethiopian material more closely than they resembled Bourbon. The similarity scores to known varieties sat in the low eighties percent, close enough to be suggestive but not conclusive.
• In 2023, the laboratory RD2 Vision analysed five samples sourced from different producers in Colombia and Costa Rica. All five carried what the lab identified as Ethiopian landrace Pink Bourbon genetics. One sample was clean; two were mixed with Bourbon material and two with Catimor. The lab's stated conclusion was that Pink Bourbon has nothing to do with Bourbon and is an Ethiopian landrace.

How Confident Should You Be?

More confident than the old Bourbon-cross story deserved, but not certain. Several caveats are worth stating plainly.

The work above is commercial genotyping reported by industry, not a peer-reviewed study with published methods and accession comparisons. Arabica as a species has an unusually narrow genetic base, so distinguishing closely related lineages by fingerprinting is genuinely difficult and reference panels matter enormously. And Pink Bourbon is not listed in the World Coffee Research Arabica varieties catalog, which does carry Bourbon, Bourbon Mayaguez 71, Bourbon Mayaguez 139 and Tekisic. That absence means there is no standardised, independently verified agronomic or genetic record for it in the field's main reference.

What can be said with reasonable confidence: Pink Bourbon breeds true from seed, which growers have relied on for years, so it is not an F1 hybrid. Its genetics cluster with Ethiopian material rather than with Bourbon. And what circulates commercially under the name is not genetically uniform.

How It Reached Huila

Pink Bourbon is associated above all with southern Huila in Colombia, and specifically with the San Adolfo area of the municipality of Acevedo, where it is reported to have been present since the 1980s. Accounts from the region describe growers keeping the odd pink-fruited trees because they performed acceptably after coffee leaf rust swept through, without knowing what they had.

The name was applied locally and descriptively: the cherries ripen pink, and the trees were growing among Bourbon. In parts of Latin America it is also called Bourbon Rosado. Neither name reflects verified parentage.

It entered the specialty market in the mid-2010s, when exporters and importers working in southern Huila began separating it as a distinct lot around 2013 and 2014. How the plant reached Colombia in the first place is unknown. The two hypotheses most often raised are that it entered deliberately as breeding material for a hybrid programme and escaped into commercial planting, or that it arrived as a misidentified seed shipment, possibly by someone attempting to import Gesha from Ethiopia.

What It Looks Like on the Tree

The defining trait is cherry colour: ripe fruit is pink to salmon-orange rather than red or yellow, a result of how the plant expresses anthocyanin pigments. Leaves are typically elongated and light green, with bronze or orange new growth. Plant architecture is inconsistent, which is part of why the material is suspected of not being a single uniform population; both tall, open, scraggly plants and shorter, denser ones circulate under the name.

That colour is a practical problem at harvest. Pickers judge ripeness by colour, and a pink cherry offers far less contrast between underripe and fully ripe than a red one. Pink Bourbon lots therefore depend more heavily than most on picker training, repeated selective passes, and post-harvest density and colour sorting.

Agronomy, and What Remains Unverified

Because Pink Bourbon sits outside the main varieties catalog, there are no standardised ratings for its yield potential, optimal altitude, nutrition requirement or disease resistance, and published field reports disagree.

On rust in particular the accounts conflict. Some Colombian growers report that the plants they keep have performed well under rust pressure, which is part of why the trees survived in Acevedo at all. Other reports, including from producers working outside Colombia, describe it as more disease-prone than modern rust-resistant selections such as Castillo and as needing intensive management. Both can be true of genetically mixed material grown in different environments, and neither has been settled by controlled trials.

What is consistent is that Pink Bourbon is treated as a high-altitude, quality-first planting. In Huila it is generally grown high, and it is managed as a microlot crop rather than a volume crop: lower expected productivity, higher labour cost per kilogram, and a price premium that has to cover both.

The genetic mixing found in commercial seed is its own agronomic risk. In the 2023 sample set, four of five lots were not genetically clean. That is not unique to this variety. A World Coffee Research quality assurance study of seed lots across Latin America found that a substantial share of tested lots showed very high rates of genetic non-compliance, with half or fewer plants matching the variety they were sold as. Anyone planting Pink Bourbon is planting seed whose identity has usually not been verified.

What Pink Bourbon Tastes Like

The cup is the reason the variety spread, and it does not read like a Bourbon. It reads like a washed Ethiopian or a Panamanian Gesha.

Typical descriptors reported by competitors and buyers include:

• Florals: jasmine, honeysuckle, rose, orange blossom
• Citrus: bergamot, pink lemonade, lime zest, grapefruit
• Stone and tropical fruit: peach, nectarine, papaya, melon
• Sweetness described as honey-like, with tea-like or green-tea finishes
• Delicate, high-toned acidity and a silky, light-to-medium body

The variety is also reported to arrive at the mill with high sugar content, which is one reason producers experiment with it so freely.

Processing

Washed Pink Bourbon is the reference expression, and the one that shows the floral and citric character most transparently. Honey processing adds body and rounds the acidity, and natural processing pushes it toward ripe tropical fruit at some cost to clarity.

Because the fruit is sugar-rich, Pink Bourbon has also become a favourite for controlled fermentation work: anaerobic tanks, cold or extended fermentations, thermal shock washing, and yeast-inoculated ferments all appear on Pink Bourbon lots. These add complexity and, done poorly, can bury the delicacy that made the variety desirable in the first place.

Roasting follows from the same delicacy. The style that suits it is a gentle, evenly developed light-to-medium roast; the aromatics that justify the price are the first thing lost to aggressive heat application.

Competition Record and Market

Pink Bourbon's reputation was built on competition tables. It placed in the top ten of the 2022 Colombia Cup of Excellence, and in 2023 it appeared twice in the World Barista Championship final round, including in the winning routine, which used a Pink Bourbon grown in Brazil rather than Colombia. Two competitors reaching a WBC final with the same variety in the same year is the kind of signal that reshapes buying.

Plantings have followed the demand outward from Acevedo and San Agustin into the rest of Huila, into Tolima and Narino, and beyond Colombia into Brazil and Central America. Lots are routinely separated, named by farm, and sold at multiples of commodity-linked prices.

Related Varieties

Pink Bourbon is not an isolated case. Colombia has become home to several varieties that carry Latin American names and Ethiopian genetics.

• Chiroso, long circulated in Antioquia as a Caturra selection, was found in a 2021 genetic study to belong to the Ethiopian landrace group, a result echoed by later commercial testing. It is now a competition variety in its own right.
• Wush Wush takes its name from a place in southwestern Ethiopia and was introduced to Colombia openly as an Ethiopian variety. It offers a useful contrast: same broad genetic background, honest name from the start.
• Gesha, also Ethiopian in origin, is the variety Pink Bourbon is most often compared to on the cupping table and, under one hypothesis, the variety someone was trying to import when Pink Bourbon arrived instead.
• Ethiopian landrace populations generally hold far more genetic diversity than the Bourbon and Typica lineages that dominate the rest of the world, which is the underlying reason these varieties keep out-cupping expectations.

What Would Settle the Question

A definitive answer needs published, peer-reviewed sequencing that compares Pink Bourbon against a broad panel of Ethiopian accessions and against the Bourbon lineage, along with a documented reference population and a stable name. Until that exists, the honest description of Pink Bourbon is the one the evidence supports: a distinctive, high-scoring Colombian coffee, almost certainly of Ethiopian descent, still carrying the name of a family it does not appear to belong to.
