Manos Juntas is a micromill in Sotara area of Colombia's Cauca region. The entire concept of this micro mill is based on simplifying tasks and responsibilities, for both producers and exporters. 

This particular offering was first purchased in its cherry form when delivered to the mill by eight local producers, on the day of harvest. Upon arrival, the Brix and pH were recorded, and the cherries are placed in large hermetic tanks for a five-daylong anaerobic fermentation: 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. The cherry is then "aged" in tanks for a period of five more days before they are taken to solar dryers. Drying takes 30–45 days.

Once dried, the coffee is cupped and samples are sent to Cafe Imports. They are then approved, milled, and shipped.
