We already know that coffee transcends national and international boundaries and Worka Chelichele washing station demonstrates just that. According to political boundaries, the station is in Gedeb Woreda but according to the congruence of microclimates and tastes, the station and the farms that deliver to it are in Yirgacheffe.
Our in-country partner, Tracon Coffee, has been experimenting with new processing methods as a way to increase value and stand out among a growing number of specialty washing stations in Ethiopia. Tracon has been trialing anaerobic fermentation with several of their washing stations in Yirgacheffe since 2015.
Farming methods in the region remain largely traditional. Yirgacheffe farmers typically intercrop their coffee plants with other food crops. This method is common among smallholders because it maximizes land use and provides food for their families.
In addition to remaining traditionally intercropped, most farms are also organic-by-default. Farmers in Yirgacheffe typically use very few — if any — fertilizers or pesticides. Most farm work is done manually by the immediate family.
To capitalize on the magnificent climate, Worka Chelichele provides training to help farmers produce better quality cherry. Training focuses on procedures for harvesting and transporting cherry.
Farmers selectively handpick ripe cherry and deliver it to the station. At intake, employees visually inspect cherry and accept only fully ripe cherry for anaerobic fermentation. Selected cherry is tightly packed in GrainPro bags and sealed shut. Cherry ferments anaerobically (without oxygen) for 18 to 24 hours.
After fermentation, cherry is carefully removed from bags and laid to dry in direct sunlight on raised beds. Workers turn cherry frequently to promote even drying. It takes approximately 2 to 3 weeks for cherry to dry.
About Anaerobic Fermentation
As more producers and washing stations enter specialty coffee, unique processing methods are a new way to stand out among the increasing number of sellers. One of those newer processing methods is anaerobic fermentation.
Anaerobic fermentation occurs in sealed containers. The seal means the microbes fueling fermentation quickly consume all the oxygen in the container. At that point, the environment become anaerobic (without oxygen). In this new environment, the microbes that typically breath oxygen have a harder time surviving and those that flourish on carbon dioxide (the typical byproduct of oxygen-breathing microbes) are able dominate fermentation.
Microbes are immensely diverse and have the potential to produce a wide array of flavors in coffees. Aerobic (oxygen-breathing) microbes produce different flavor outcomes than anaerobic ones, so we have the potential to produce vastly different flavors simply by changing the available resources for microbes.
