About
Farmers in Peru usually process their coffee on their own farms using the Fully washed method. Cherry is usually pulped, fermented and dried in the sun. Traditionally, smaller farmers would use tarps laid on the ground or under the roof of their homes. Increasingly, cooperatives are establishing centralized drying facilities – usually raised beds or drying sheds where members are encouraged to dry their parchment. Some farmers are beginning to adopt these practices on their own farms, and drying greenhouses and parabolic beds are becoming more common as farmers pivot towards specialty markets.
After drying, coffee will then be sold in parchment to the cooperative. Producers who are not members of a cooperative often have the opportunity to sell on to cooperatives, as well.
The Mountain Water process offers an alternative to consumers concerned by methyl chloride (MC) and ethyl acetate (EA) processes. Because water processing does not use added chemical compounds, coffees can maintain organic certifications and customers can be assured of the absence of additional chemicals.
The difficulty of decaffeination is that many of the flavor compounds that give coffee its excellent taste are, like caffeine, water-soluble. Thus, any decaffeination method needs to effectively single out and remove the caffeine molecule while preserving as many of the flavor compounds as possible.
The process begins with a batch of green coffee beans that are soaked in water to remove the caffeine. In water, many of the flavor compounds are also removed as well, but don’t worry! This is intentional and will preserve help flavor in the future.
This first batch of beans are then discarded. This process only needs to happen once because the mixture produced by soaking those beans, called green coffee extract (GCE), can be maintained and reused to decaffeinate many batches of green beans.
The principle behind water processing is that water can only absorb a set amount of flavor compounds and caffeine before it is completely saturated. When water is fully saturated, it cannot accept (and remove) any more flavor compounds, even if they’re in the coffee. That first batch of beans created a fully saturated water mixture, the GCE. In order to process the beans for decaffeination, the GCE is run through a filter to remove only the caffeine.
Now the GCE is fully saturated except for caffeine. When a new batch of green beans are placed in the GCE, the only compound from the new beans that will be accepted into the GCE is caffeine, everything else will remain in the beans because the GCE is already saturated with those chemicals and unable to ‘take’ anymore.
