The Guji region, located in the southeast of Yegashefi, is adjacent to Sidamo and Gaideo, and is an area with complex topographical changes such as towering mountains, highlands, plateaus, valleys and plains.

The geology of this area belongs to the nutrient-rich black soil (Vertisol), the depth of the soil is nearly two meters, and the average elevation is more than 1800 meters. The significant temperature difference between day and night created by geographical characteristics makes the local area have various local conditions for producing high-quality coffee.

The biggest advantage of this place is that the soil vitality is maintained through the circulation of natural organic matter, using the withered leaves or litter of surrounding trees, plant residual roots and so on as natural fertilizer.
