This coffee’s roasted in our filter style — meaning it’s designed to shine as black coffee rather than with milk. That doesn’t mean you have to brew it as a pour-over though. You can make it however you like — espresso, moka pot, AeroPress or anything in between. We simply roast it a little lighter to highlight the bean’s origin flavours giving you a cup that’s clean, vibrant and full of clarity.

Lighter roasting keeps more of the natural acidity and sweetness intact which makes for a beautifully expressive black coffee. This coffee is best enjoyed without milk as it’s too acidic and the flavours don’t pair well once milk is added.

If you prefer your milk coffee with richer caramel, toffee or nutty flavours you might enjoy our espresso range more. Those roasts are taken a little darker to bring out deeper sweetness and balance beautifully with milk.

Origin and Sourcing

Varietal: Bourbon Aji, Sudan Rume

?

Bourbon Aji is a rare and intriguing coffee variety emerging from Colombia, known for its vibrant cup profile and unique origin story. Named after the spicy chili pepper (“ají” in Spanish) due to its bright red, elongated cherry shape, this variety is believed to be a natural mutation or selection of Bourbon, though its exact genetic lineage is still under research. Grown mostly in small quantities at high altitudes, Bourbon Aji has caught the attention of specialty producers for its striking flavor clarity, often showcasing intense florals, tropical fruit, and a sparkling acidity reminiscent of Ethiopian landrace varieties.

Sudan Rume is a rare and genetically pure Arabica coffee variety originating from the Boma Plateau in South Sudan — one of the birthplaces of Arabica itself. It’s part of the Coffea arabica species but distinct from the more common Ethiopian landraces, offering a unique genetic profile that contributes to exceptional flavour potential. Though naturally low-yielding and delicate to cultivate, it produces cherries of remarkable aromatic complexity, making it highly prized among specialty coffee producers and competition roasters. In the cup, Sudan Rume is celebrated for its refined clarity and floral intensity, often expressing notes of jasmine, tropical fruit, and delicate citrus with a silky, tea-like texture. Its rarity and cup quality have made it a foundational parent in modern hybrid development — notably contributing to renowned varieties such as SL28, Ruiru 11, and Sidra. Because of its limited production and demanding growing conditions, coffees labelled as pure Sudan Rume are exceptionally scarce and sought after by roasters chasing distinctive, high-scoring lots.

Processing Method: Natural

?

The natural process involves drying whole coffee cherries under the sun, allowing the beans to absorb flavors from the fruit as they dry. This results in a coffee with a heavy body, fruity sweetness, and complex flavors. It’s commonly practiced in Ethiopia and Brazil, where the climate is conducive to sun-drying.

Producer: Nestor Lasso

Farm: El Diviso

Region / Area: Huila, Bruselas

Altitude: 1850 MASL

Sourcing Partner: Direct From Farm

Coffee Storage: Frozen

?

For our exotic coffee, we store all the green beans frozen at -22°C in commercial freezers. This locks in freshness, halting enzymatic reactions that degrade flavor. Upon arrival we separate into small 2-3kg vacuum-sealed lots and freeze so that our greens do not age and we can sell these exotic coffees for years to come or until sold out.

Roast Details

Roast Style: Filter

?

Filter roasts are lighter with a shorter development time, designed to highlight clarity, acidity, and fruit-driven complexity — perfect for black coffee and filter methods. These roasts can also be used for espresso, especially if you enjoy brighter, more vibrant shots. Try longer brew ratios or turbo shots to tame acidity and bring out sweetness. Espresso roasts, on the other hand, are developed further to encourage deeper caramelization and Maillard reactions, producing richer, chocolatey, and nutty flavours that shine in milk and offer a fuller-bodied espresso. We don't usually roast omni (one roast for all brew methods) — in our experience, it tends to be a compromise that's average at both. But occasionally, for larger lots or versatile blends, we may do an omni roast to suit both black and milk drinkers.

Roasted On Machine: Roest L100 Ultra

?

The ROEST L100 Ultra is the most advanced sample roaster in its class, combining the precision of the L100 Plus with next-generation hardware upgrades and new airflow technology. A redesigned, fully perforated drum with reversible rotation introduces a counterflow mode that channels air directly through the bean mass—allowing faster, more efficient heat transfer and enabling lighter roasts or second crack in under 90 seconds. With upgraded 5 GHz Wi-Fi, a faster processor, built-in pressure sensor, and refreshed UI matching the P3000, the Ultra offers better batch consistency (even at 50g), improved airflow calibration, and lower energy consumption. It’s a serious tool for roasters wanting unmatched control, speed, and repeatability—while still fitting neatly on the benchtop.

Taste Profile

Tasting Notes: Red berries, blueberry, raspberry. Sweet and balanced with a clean finish. (Aji Bourbon + Sudan Rume Fruit Forward Berry Ensemble Natural)

Cupping Score: 90.0

?

Our coffees are scored using the Specialty Coffee Association (SCA) protocol by Q Grader–certified cuppers. A score of 80+ qualifies as specialty grade — clean, well-processed, and high quality. 80–84 coffees are more common and often used in blends. 85–87 are brighter, more complex, and better suited for high-quality filter brews. 88–90 are exceptional, and 90+ coffees are ultra-rare, often Cup of Excellence (COE) winners — the best in the world.

Suitable with Milk? No

?

Some of our light roasted filter coffees are bursting with bright, fruity acidity — think citrus, berries, or tropical notes. While these flavours shine on their own, they don't always play well with milk. The acidity can clash with milk's natural sweetness and creaminess, sometimes creating sour or chalky flavours.

Decaffeinated? No

Fruit Forward Berry Ensemble

Beautifully encapsulates a variety of berry flavours within a fruit-forward coffee profile, evoking a diverse and harmonious ensemble of fruity notes. The art of producing a great fruit-forward coffee lies in achieving a balanced flavour profile. While the fruitiness is the highlight, it is harmoniously balanced with sweetness, body and a clean finish. This is the mark of skilled coffee processing.

About the Varieties

This lot brings together two of El Diviso’s rarest varieties. Ají Bourbon is a mutation of an Ethiopian landrace; locally it’s called Ají Borbón because the fruit mucilage has a slight smell and flavour of red pepper. Sudan Rume is a wild variety discovered in 1942 on the Boma Plateau in South Sudan, near the Ethiopian border, prized for its disease resistance and vivid fruit and floral character.

Processed together through Nestor’s natural Fruit Forward Berry Ensemble protocol, the two varieties layer into a sweet, berry-driven cup — red berries, blueberry and raspberry — kept in balance by a clean finish.
