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: SL28, SL34

?

Developed by Scott Agricultural Laboratories in Kenya, SL28 is known for its excellent drought resistance and stunning cup quality. It exhibits bright, winey acidity with notes of blackcurrant and citrus. SL28 is one of the reasons Kenyan coffees are so revered. However, it’s highly susceptible to leaf rust and pests.

Also from Kenya’s Scott Labs, SL34 shares a similar profile to SL28 but performs better in wetter climates. It offers a rich body and acidity, with bold fruit notes and complexity. SL34 is commonly interplanted with SL28 to hedge against environmental extremes.

Producer: Aguthi Farmers' Co-operative Society

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: Peach, cranberry, raspberry, stewed stone fruit, milk chocolate and brown sugar - juicy.

Cupping Score: 87.0

?

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

Medium Roast - Roasted on Roest L100 Ultra

Thageini Wet Mill

Thageini is one of four mills run by the Aguthi Farmers' Co-operative Society in Nyeri, and the second largest by members, with around 350 men and 100 women delivering cherry. The Society, around 2,000 members in total, runs training in farm management, picking, sorting and agronomy, and holds workshops so members can learn from each other.

Project Origin has worked with Aguthi since 2017. After Thageini supplied a run of exceptional washed coffees in 2018, they invested in carbonic maceration infrastructure at the mill in 2019 and funded new drying beds to lift quality further.

Nyeri

Nyeri sits on the slopes of Mount Kenya, where rich red volcanic soils, high altitude (1,650-1,800m here) and two rainy seasons produce some of the most sought-after coffee in the world - famous for bright, juicy acidity and deep berry fruit.

Supernatural - Karibu

Karibu means 'welcome'. Early-harvest cherries are hand sorted at the mill for 90%+ ripeness, then piled on raised beds in cocoons for four days to ferment aerobically, driving fruit intensity. They are then unwrapped and turned regularly to keep sweetness and clarity while drying for 25-30 days. Project Origin cups the lots with Thageini to curate this Signature Supernatural profile.

Expect peach, cranberry, raspberry and stewed stone fruit with milk chocolate and brown sugar - juicy and sweet.

About the SL28 & SL34 Varieties

SL28 and SL34 were selected in the 1930s by Scott Agricultural Laboratories in Nairobi, which is where the 'SL' comes from. SL28 was bred from drought-resistant Tanzanian stock, while SL34 traces back to French Mission Bourbon trees at Kabete. Together they became the backbone of Kenyan specialty coffee and remain the varieties most smallholders in Nyeri grow today.

Both are tall, low-yielding trees that need careful farming, but roasters around the world seek them out for their intense, juicy acidity and deep red-fruit and blackcurrant character. SL28 tends to bring the vivid, sparkling fruit; SL34 adds body and sweetness at high altitude.

Here the Supernatural process layers ripe peach and stewed stone fruit over the varieties' classic raspberry and cranberry brightness.
