Introduction:The Red Jade CM Natural coffee beans from Ethiopia’s Yirgacheffe Kochere region combine carbonic maceration with sun-drying to deliver a unique fruity aroma and rich body. This article delves into the regional background of these beans, the principles behind CM processing, and details their flavor profile and recommended brewing methods to help you better understand this highly acclaimed specialty coffee.
Ethiopia’s Yirgacheffe Kochere region has long been known for its high altitude and unique microclimate, producing coffee beans with complex and layered flavors. Among them, the Red Jade CM Natural series launched by the Origin Project employs carbonic maceration (CM) fermentation, followed by sun drying, to bring out intense and nuanced fruit notes, making it a favorite among many coffee enthusiasts.
The CM processing method is actually derived from the carbonic maceration technique used in winemaking. In wine production, whole uncrushed grape clusters are placed in a sealed environment filled with carbon dioxide to ferment, slowing down oxidation and concentrating the fruit aromas. When applied to coffee, this involves fermenting parchment or de-pulped beans in a sealed space with high concentrations of carbon dioxide and controlled temperature and humidity. This method effectively reduces excessive oxidation and alcohol-like flavors, enhancing the purity and consistency of the coffee’s flavor.
The CM Selection series launched by the Origin Project is limited to batches personally monitored and processed by their team, with each batch undergoing strict selection. In the processing workflow, the CM fermentation stage comes first, followed by either sun drying or washed processing based on product design. This technique has been tested in Ethiopia since 2017, and now the “CM Selection Ethiopia Series” has entered its third year of development, with relatively mature and stable technology.
The flavor profile of Red Jade CM Natural coffee features distinct red and yellow fruit characteristics, such as jammy notes, berries, and citrus aromas. After CM processing, the coffee exhibits a rich yet refreshing mouthfeel, with concentrated and layered flavors while maintaining a clean aftertaste and medium body—making it ideal for coffee drinkers who enjoy fruity profiles.
These beans come from the Kochere area within Ethiopia’s southern Gedeo Zone. The region boasts mineral-rich acidic soil, coupled with an altitude ranging from 2000 to 2200 meters , creating optimal growing conditions for coffee beans. Compared to other Ethiopian regions, Kochere-produced coffee often features gentler acidity but still retains bright fruit and floral notes, along with a more rounded and balanced mouthfeel.
The CM Natural process used in the Red Jade series further amplifies these regional characteristics. During fermentation, the natural sugars and enzymes in the fruit pulp interact in an oxygen-deprived environment, releasing a wealth of aromatic compounds, ultimately resulting in complex flavors such as chocolate toffee, dark berries, cherries, tropical fruits, and plums , along with subtle salty-savory notes that add depth and lingering finish to the overall flavor.
When brewing this coffee, a pour over method is recommended to better highlight its multi-layered fruitiness and sweetness. A medium-fine grind (similar to granulated sugar) is generally advised, with water temperature controlled at 90-92°C, using a step extraction method—for example, brewing around 30 grams of coffee with approximately 500 milliliters of water, with total brew time between 2 minutes 30 seconds and 3 minutes to fully showcase its balanced flavor and rich body.
In summary, the Red Jade CM Natural coffee beans not only showcase the premium terroir of Ethiopia’s Kochere region but also introduce a new dimension of flavor through CM processing. Whether you’re a coffee novice or a seasoned enthusiast, this coffee—combining fruity notes, sweetness, and a full body—is worth adding to your tasting list to experience a unique Ethiopian specialty flavor.
