The Curator's Archive

Un.Common approaches coffee with a focus on clarity and vibrancy. Their partnership with producers like Franceschi demonstrates a commitment to sourcing coffees that represent the absolute peak of agricultural innovation and heritage.

Our inaugural entry is a definitive statement. The Geisha variety represents the apex of genetic potential in coffee; Franceschi represents the living history of Panamanian heritage. This lot is the work of Carlos Aguilera (formerly of Carmen Estate) and Jean Paul Langenstein (of the Ratibor Hartmann lineage). Together, they have not just executed, but perfected the washed process, delivering a cup of uncompromising clarity.

Based in Amsterdam, DAK Coffee Roasters represents the forefront of modern European coffee. Founded by Louis-Philippe and Veronique, their approach is defined by a fearless embrace of experimental processing and distinctively light roasting. They do not fear funk; they tame it.

If our inaugural release was a study in terroir, Ledger 002 is a masterclass in processing technique. At Finca El Placer, Ramirez operates less like a traditional farmer and more like a laboratory director. Through rigorous control of fermentation and carbonic maceration, Ramirez has achieved a profile that is intentional, distinct, and impossible to replicate by accident. We selected this lot for you because it is an exclusive partnership between our most integral roasting partner and one of the top Colombian producers in the world.

The Architects of Modern Coffee. Established in 2007, Coffee Collective is a foundational pillar of the modern Nordic style. In an industry obsessed with the "new," they possess something rarer: Provenance. They set the global standard for transparency, paying prices far above the fair-trade threshold long before it was industry practice.

The White Honey process is a rare anomaly in Ethiopian coffee. By removing the skin but retaining a calculated layer of mucilage during drying, this hybrid technique bridges the gap between two worlds: capturing the enzymatic sweetness of a Natural while preserving the crystalline acidity of a Washed. The result is a profile that completely dismantles expectations of the standard 74158 varietal. This level of precision is why Mulugeta Muntasha is a Cup of Excellence winner, and why Coffee Collective paid 172% above the market rate for this lot. While the region is historic, Mulugeta's approach, and the compensation it commands, is relentlessly modern.

Operating out of Zurich, Switzerland, Rose represents the forefront of the elite European roasting model. Under the precise direction of Matt Winton (WBCC 2021), they reject volume in favor of a strict curation model focused exclusively on singular, uncompromised lots.

Jose "Pocho" Gallardo applies an engineer's absolute rigor to cultivation and processing at Finca Nuguo (BOP Winner). This specific lot, grown on the family parcel adjacent to his primary farm, represents a highly calculated approach to the Natural process. By transporting the ripe cherries down into the valley, Gallardo achieves exact environmental control. The coffee undergoes a strict four-day anaerobic fermentation before a meticulous 30-day drying phase on African beds, halted exactly at 11% moisture. The result is a profile that dismantles the heavy, over-fermented characteristics often associated with natural processing. It is a flawless, highly restricted execution of the Panamanian Geisha.

Based in Brussels, Belgium, MOK Coffee represents the intersection of uncompromising sourcing and technical roasting precision. They operate with a minimalist philosophy, focusing on transparency and elevating the innate, delicate characteristics of the world's most exclusive lots.

This is the final, highly exclusive release from Felipe Contreras' 2025 crop. The team at Finca Gascón operates with a profound respect for permaculture, integrating regenerative methods to create a perfect microcosm for the Geisha varietal. This specific lot undergoes a demanding "Double Oxidization" hybrid washed process. The cherries are oxidized on a fermentation pile for 48 hours to build intense sweetness, then depulped and oxidized again for another 48 hours to lock in absolute crystalline clarity. The result is a profile that is deeply complex, highly restricted, and ruthlessly clean.

Based in Oslo, Norway, Tim Wendelboe is an institution of uncompromising agronomic rigor. He rejects the traditional volume-based roaster-farmer dynamic, opting instead for deep, multi-year partnerships built on shared experimentation and biological farming. His approach to roasting prizes pristine clarity and sweetness over all else.

Terroir and varietal are typically treated as a fixed equation. A Kenyan bean belongs in Kenyan soil. But true innovation requires dismantling the equation.

At Finca El Puente, legendary producers Marysabel Caballero and Moises Herrera collaborated with Wendelboe to plant Batian—a resilient Kenyan hybrid cultivar—deep within a small forest in Honduras. The protocol was absolute: no fungicides, no synthetic fertilizers. This was a pure biological farming trial guided by the strict principles of Wendelboe's own Finca el Suelo project.

The result is striking. Cultivated from young trees, this Kenyan hybrid has entirely shed its traditional bright, aggressive profile. Instead, it offers a deeply restricted, flawless structure. We secured Batch 14 because this experiment is in its infancy. It is a rare calibration of excellence, and a glimpse into the future of cultivar migration. It is up to you to experience it.

Based in London, Special Guests Coffee works on a numbered release model: one rare lot at a time, in limited supply, retired when it sells out. Paul Ross, a two-time UK Barista Champion, founded the roastery in 2022. The sourcing stays at the rare end of the market. Competition lots, experimental processes, and varietals most roasters never get their hands on.

There was no Ledger in May. The reason was personal. To everyone who kept their subscription through the gap: thank you for waiting.

La Josefina sits in Ecuador's Amazonian foothills, between Sumaco and Cayambe-Coca, on soil fed by ash from El Reventador. Leopoldo Andrade and Ligia Merizalde founded the farm. Juan David Benavidez runs the processing. This Typica Mejorado gets a saline wash, a 24-hour fermentation, then 35 days of slow drying on shaded African beds inside polytunnels. The control is in that drying. It produces a Natural without the heaviness the process usually brings.

The note is mango.

I chose this lot for that note. It is an ode. Those who know, already know why. Either way, it is one of the cleanest naturals Ecuador has put in a cup this year, and that is reason enough.

Tanat roasts in Paris and runs cafés in Paris, Lille, Nantes and Marseille. Founded in 2016 as Kawa and rebranded in 2025, the roastery buys on a single thesis: honour the origin without heavy roasting intervention. Co-founder Alexis Gagnaire is a Q Grader and the house green buyer, a third-place finisher at the 2019 World AeroPress Championship and runner-up at the 2021 French Coffee Roasting Championship. The roastery operates on a flat structure in which every member of the team holds an equal say in what gets bought and how it is roasted.

Seven records into this archive, every selection has been made on control. Clarity, structure, a process that stays where the producer put it. No. 008 is selected on the inverse, and I want to be exact about what that means. Funky, in specialty coffee, usually describes a fermentation that got away from someone: acetic sharpness sitting on top of the fruit, a solvent edge, a flatness underneath it all. It is a defect wearing a compliment.

What Lasso does at El Diviso is the governed version of the same chemistry. Cherries come in at full ripeness and oxidise in open air for 48 hours. Twelve hours of rest. A further 60 hours held under temperature control between 30 and 40°C. The fruit then moves into sealed tanks for 24 hours of anaerobic fermentation with the mosto recirculated through the mass, returning the cherry's own sugars and its established microbial population to the ferment rather than introducing anything foreign to it.

Then the thermal shock at 60°C. Fermentation is a curve, and every hour past its peak trades aromatic complexity for acetic harshness. The conventional ending is to move the coffee onto a drying bed and let the activity taper on its own schedule. Lasso ends it on a chosen minute. The volatile compounds assembled over those 132 hours are fixed in place before the microbial population can convert them into sharpness. Drying follows across sun and dehumidifier, 60 to 70 hours at roughly 35°C, down to a final moisture of 10.5 to 11.5 percent.

The body is what convinced me. Ombligon carries a syrupy weight that naturals at this intensity almost never hold, and that weight is the reason the fruit reads as sweet rather than sharp. This is the first coffee I have imported from Tanat and the first Ombligon to enter the Ledger. Both were overdue.

Datura roasts in Paris, founded April 2024 by Loïc Perneau after four years behind the bar as a barista and manager. He still works the bar alongside roasting. The roastery keeps no fixed espresso or filter profile: every lot is approached on its own terms. Datura buys at the top of the Panama and Ethiopia bands and built its catalogue around lineage rather than flavor category, the same discipline this selection was chosen for.

Natural-process Ethiopia has spent the last few years chasing intensity through intervention: extended mosto macerations, inoculated ferments, anaerobic holds before the cherry has even reached a bed. Some of those lots are genuinely excellent. No. 009 goes the other direction. No cofermentation, no infusion, no manufactured funk. What's in the cup is what the cherry and the station did on their own.

Faysel Abdosh founded Testi Specialty Coffee after building several washing stations in Guji. Ayla, established in 2018, was Testi's first station in Sidama, named after his niece. The company now works directly with around 800 smallholder farmers around Bensa, most cultivating less than two hectares, coffee grown under the shade of native Birbira, Wanza, and Acacia trees. Testi has put some of what it earns back into the area directly: school construction, better water access, connections to the electricity grid.

The process itself is unglamorous by design. Farmers handpick only ripe, red cherry and deliver it to Ayla, where it's inspected, then dried whole on raised beds for 15 to 20 days, hand-sorted and raked the entire way through. Nothing added, nothing sped up. The variety names, 74110 and 74158, are catalogue numbers: the "74" marks 1974, when the Jimma Agricultural Research Centre first selected them.

This lot lands at the top of the Ethiopian natural calendar, and it tastes like it: juicy, bright, structured berries running into guava, acidity that holds its shape instead of collapsing into jam. It's the reference case for what an Ethiopian natural is supposed to taste like before anyone starts adding variables to it.
