The current roast · small-batch, roasted to order
Fermentation shapes every coffee. We source lots where it's controlled with intention — and roast each one with precision. Every bag ships within two days of roasting.
The same beds that put four lots in Ethiopia’s Cup of Excellence top ten — built by Mulugeta Muntasha in 2021, in a village that had only just planted its first coffee trees. This is what those beds do sealed.
| Origin | Ethiopia, Sidama (Bursa, Arbegona) |
| Process | 96h Anaerobic Natural |
| Roast | Light-Medium |
| Notes | Papaya, Strawberry wine, Watermelon, Tea |
Mulugeta Muntasha grew up in Bursa when Bursa grew no coffee. He learned the trade driving cherry trucks in Arsi, then came home in 2021 to build his own station — just as his village planted its first trees. Within two years, four of Ethiopia’s top-ten Cup of Excellence lots came off his beds, including the national winner.
| Origin | Ethiopia, Sidama (Bursa, Arbegona) |
| Process | Washed |
| Roast | Light-Medium |
| Notes | Apricot, Honeysuckle, Raspberry |
Deep volcanic soil, serious altitude, heritage SL trees — and Norman Mukuru, the agronomical engineer who came east to build another exporter’s operations and stayed to build The Coffee Yards. Same beds as our 48-hour; the clock is the only thing we moved.
| Origin | Uganda, Mt. Elgon |
| Process | 96h Anaerobic Natural |
| Roast | Light-Medium |
| Notes | Guava, Overripe peach, Mulled wine |
Norman Mukuru is why Mt. Elgon coffee now reaches people who can taste the difference. An agronomical engineer from Uganda’s far west, he came east to build processing for one of the country’s largest exporters — then stayed to build his own.
| Origin | Uganda, Mt. Elgon |
| Process | 48h Anaerobic Natural |
| Roast | Light-Medium |
| Notes | Chocolate fudge, Banana flambé, Toffee |
El Vergel’s own plot, not bought in. The Bayter family keeps 28 varietals under trial and brought koji to Colombian coffee before anyone else — Papayo is the rarest thing they grow, and they kept it for the estate.
| Origin | Colombia, Tolima |
| Process | 96h Anaerobic Natural |
| Roast | Light-Medium |
| Notes | Strawberry, Mango, Pomegranate |
Oscar Hernández is the third generation on Los Nogales, settled by his grandparents outside Pitalito in 1952 and first place in the 2005 Cup of Excellence. Trained in environmental management, he has run it since 2013 as a working laboratory — trialling varietals, refining ferments, conserving the forest and water the farm depends on.
| Origin | Colombia, Huila |
| Process | 96h Anaerobic · Mosto Natural |
| Roast | Light-Medium |
| Notes | Tropical fruit, Banana, Rose, Tangerine |
We believe controlled anaerobic fermentation unlocks flavor profiles impossible through conventional processing. So we seek out producers who calibrate it — cherry selection, fermentation duration, temperature — and roast each lot to reveal the full potential of its origin.
Transparency, producer to cup
Six lots, five producers, named. We source from farms doing the hardest work — experimental fermentations, varietals pushed to their limits, microlot discipline. Every bag names the hands behind it.
Colombia · Fresno, TolimaAvocado growers until disease and a price collapse wiped out the crop in 2006. Martha Bayter replanted in coffee; the family turned the estate into a fermentation laboratory that now runs its own research into the yeasts and bacteria behind every ferment.

Colombia · Pitalito, HuilaEighty years on one hillside. Rather than sell after his father's death, Oscar Fernando Hernández modernised the farm — and carries the farm's own microbes forward batch to batch, a mosto starter saved from the previous ferment of the same variety.

Uganda · Mt. ElgonHe built collection and processing operations for one of Uganda's largest exporters. When it collapsed he kept the mountain networks and built his own hub outside Mbale — and sells us the same cherry fermented two ways, 48 hours and 96.

Ethiopia · Arbegona, SidamaHe drove trucks of other people's cherry before building his own drying station in 2021. The year after it opened, four of Ethiopia's top ten Cup of Excellence lots were processed there — including the first-place coffee.

Colombia · Manzanares, CaldasSmallholders across northern Tolima and southern Caldas grow and pick; drying — the riskiest, most space-hungry step for a small farm — is centralised at El Vergel. Our Guamo is named for one of the native shade trees the project plants.

Most coffees are named for a place. This one is named for a plant — a rare Colombian cultivar with outsized beans, grown on small plots at El...
What People Are Saying
Ethiopia Sidama Anaerobic Natural
The Ethiopia Sidama completely changed how I think about coffee. The blueberry notes are unreal — it tastes like coffee at the top of its range.
Colombia 72h Anaerobic Natural
I ordered the Colombia 72h Anaerobic Natural Pink Bourbon on a whim and it blew me away. The fruit complexity is like nothing I've had before. Already reordered.
Costa Rica - 36h Anaerobic Honey
I've been into specialty coffee for years — Anaerobic still caught me off guard. The Costa Rica had this caramel-meets-citrus thing that I've never tasted in a honey process. Only reason for 4 stars: I wish they had bags bigger than 10oz.
Brazil Mogiana Natural
Added the Brazil Mogiana to round out my order — just a classic natural, as I wanted a solid daily drinker alongside the anaerobics. It's honestly great on its own. Rich, chocolatey, no gimmicks.
Peru Gesha Anaerobic
Bought the Discovery Set as a small gift for my partner. We both fell in love with the Peru Gesha — the jasmine and tropical fruit notes were incredible.
