What Is Sidamo Coffee and Why Does G1 Matter?
Sidamo is a specialty coffee region in Ethiopia, and its natural process has moved from rough to refined. Traditional natural lots were spread on the ground to dry without sorting, which caused uneven ripeness, unstable green bean quality, and off-flavors. Improved methods raise cleanliness and sweetness enough to reach the top G1 grade.
The refined approach to how to process coffee beans starts with picking only fully ripe deep-red cherries and sorting defects before drying. Cherries dry on raised beds, are turned for even moisture loss, and every three to five days workers remove moldy or defective beans. A final sorting after milling follows.
Sidamo is a renowned specialty coffee region in Ethiopia, and its natural processing method has evolved from rough to refined. Traditional natural processing, due to direct sun-drying on the ground and lack of sorting, resulted in unstable quality, easily picking up off-flavors and defective beans. The improved natural method, through steps such as harvesting only fully red cherries, drying on raised beds, and manually removing defects, has greatly enhanced the coffee's cleanliness and sweetness. This article provides a detailed analysis of the flavor characteristics of natural Sidamo and explains how final sorting achieves the highest grade, G1. The natural Sidamo recommended by Front Street Coffee is a prime example of this refined processing and is well worth savoring for coffee enthusiasts.
In the past, Ethiopia's natural processing method was quite rough—farmers would spread coffee cherries harvested from the wild directly on the ground to dry. This approach had two main drawbacks: first, the cherries were not sorted or graded, leading to uneven ripeness, which resulted in significant fluctuations in the final green bean quality and a high proportion of defective beans; second, the processing sites were often empty lots near homes, where impurities and dirt on the ground could easily cause the coffee to absorb off-flavors.
To address these flaws, the improved natural method emerged: first, only fully ripe, deep-red coffee cherries are harvested, and defect sorting is completed at the processing station before drying, making the beans more consistent in size and ripeness. Second, raised wooden frames or drying beds are used to avoid direct contact with the ground, preventing the beans from absorbing off-flavors. During drying, careful turning is required to ensure even moisture evaporation; every three to five days, workers manually remove moldy or defective beans. Through such meticulous care, by the time drying is complete and before the de-pulping stage, the brightly red coffee cherries have already reached a level with very few defects.
After obtaining the green beans, a final sorting is sometimes carried out to pursue even more perfect flavors. Therefore, this natural Sidamo can achieve the highest grade—G1.
