Colombia Huila Anaerobic Process
"Abnormal Offerings for Coffee Lovers."
The Skeleton Key Series is a new set of small batch single origin offerings from Brass Ring Coffee. These are coffees that we find to be special or "abnormal" in some way or another. Some of these coffees may come from special farms, use experimental processing techniques, unique typicas, or just have an extremely special flavor or character. You can always count on a Skeleton Key coffee to transport you to somewhere special when you close your eyes to take the the first sip.

"Although growing coffee includes lot of science by default. Coffees like this are taking it to the next level.
This is a controlled fermentation natural processed coffee, done in sealed tanks – as opposed to just drying the cherries slowly outside, letting them ferment naturally. This allows farmers and processors to really dial in the natural processing.
Manos Juntas is a micromill in Sotara area of Colombia’s Cauca region, operated and managed by Banexport. The entire concept of this micromill is based on simplifying tasks and responsibilities, for both producers and Banexport.
This particular offering was first purchased in its cherry form when delivered by local producers on the day of harvest in Huila. Upon arrival, the Brix and pH were recorded, and the cherries are placed in large hermetic tanks for a five-day-long anaerobic fermentation and transferred to Cauca: Each tank is labeled with the name of the producer, to retain traceability. During this period, nitrogen gas is introduced into the tanks in order to stimulate the yeast. Brix and pH are measured constantly through this process and are used to determine the stopping point for fermentation; the coffee is then subjected to 20°C temperatures in order to cease fermentation and remove the yeast and other microorganisms.
Once dried, the coffee is cupped and the lots created.
Banexport believes that when it comes to a breakdown in factors that contribute to quality:
- 50% is determined by crop production (fertilization, pruning, and proper harvest of cherries)
- 50% is determined by post-harvest processing (fermentation, pulping, drying, and storage)
Based on this understanding, Banexport decided to establish Manos Juntas Micromill, in which they purchase cherries from producers and manage the processing, drying, and storage themselves. This model allows producers to focus on healthy production of specialty coffee, while the meticulous work of sorting, processing, drying, and storing is managed by Banexport’s team.
Key takeaways about this program:
- Producers deliver and sell coffee in cherry form to Banexport, by total weight. The riper the cherry, the heavier it is. This encourages better harvest practice that directly correlates to higher quality.
- Producers get paid upfront for their coffee, typically producers have to wait 35 to 40 days for coffee to dry before selling it.
- Banexport guarantees to pay producers a fixed price well above the market value for these cherries.
- Producers involved are from surrounding farms. This means they need only to travel a short distance to deliver coffee, as opposed to driving many kilometers into town.
- Coffee infrastructure, like drying beds, fermentation tanks, and depulpers, can be very expensive to purchase and maintain. With this model, farmers can forgo all of this hassle and focus on maintaining healthy trees.."
