Guji GUJI

The Guji region has been attracting increasing attention in recent years, delivering impressive results in both flavor presentation and quality consistency. It was originally under the jurisdiction of the Sidama region, and in 2010, with approval from the Ethiopia Commodity Exchange (ECX), it officially became an independent region. Guji is located southeast of Yirgacheffe, adjacent to Sidama and Gedeo, with towering mountains, interlaced highlands, plateaus, valleys, and plains, and quite complex terrain changes. The geology of the area is mainly fertile black soil (Vertisol), with a soil layer nearly two meters thick and an average altitude of over 1,800 meters. The obvious day-night temperature difference brought by the special geographical environment provides an ideal terroir foundation for producing high-quality specialty coffee. The region's greatest advantage lies in maintaining soil vitality through natural organic matter cycles—fallen branches and leaves from surrounding trees, as well as residual plant roots, all become natural sources of fertilizer.

Natural NATURAL

The natural method can be considered a time-honored way of processing green coffee, and this batch of beans from the Guji region at FrontStreet Coffee uses exactly natural processing.

1. Removing floating beans

The harvested coffee cherries are poured into a large water tank; fully developed cherries sink to the bottom, while unripe or overripe fruits float on the surface, and these floating beans need to be picked out and discarded.

2. Sun drying

Then the whole coffee cherries, with pulp and skin still attached, are spread out on a drying bed to receive sunlight, allowing the moisture to evaporate naturally to about 12%. Depending on the climate conditions of the origin, the whole process takes about two to four weeks.

3. Hulling

After the cherries have completed natural drying, a hulling machine removes the dried hard skin, pulp, and parchment layer all at once, and the green beans are revealed.

Local Heirloom HERILOOM

The variety used in this Front Street natural Guji belongs to Ethiopia's local heirloom varieties. The reason they are collectively called heirloom is that Ethiopia has an extremely large number of coffee varieties, making it a natural gene treasury of Arabica; on the one hand, variety identification and classification are extremely difficult, and on the other hand, the Ethiopian government, for protection reasons, is unwilling to disclose specific variety information to the outside, so they are collectively referred to as [Heirloom native species].
