FrontStreet Coffee invites you to learn about the story of natural Guji—let's get started!

Guji Region

The Guji region has garnered significant attention in recent years, achieving impressive results in both flavor expression and quality. Formerly part of the Sidamo region, Guji was established as an independent region by the Ethiopia Commodity Exchange (ECX) in 2010. Located southeast of Yirgacheffe, the Guji region borders Sidamo and Gedeo, featuring complex terrain with towering mountains, highlands, plateaus, valleys, and plains. The region's geology consists of nutrient-rich Vertisol soil with depths reaching nearly two meters, and the average altitude exceeds 1,800 meters. The significant temperature differences between day and night, created by these geographical characteristics, provide all the terroir conditions necessary for producing premium specialty coffee. The region's greatest advantage lies in maintaining soil vitality through natural organic matter cycles, using fallen leaves and decaying materials from surrounding forests, along with plant root residues, as natural fertilizers.

Natural Process

The natural process can be described as an ancient method of green bean processing. FrontStreet Coffee's coffee beans from the Guji region are natural-processed.

1. Remove Floating Beans

The harvested coffee cherries are poured into large water tanks. Mature, full cherries will sink to the bottom, while underdeveloped or overripe cherries will float to the surface. These floating beans must be removed.

2. Sun Drying

The entire coffee cherries, with their pulp and skin intact, are placed on drying patios for sun drying until they reach a moisture content of about 12%. This process takes approximately two to four weeks, depending on the climate of the origin.

3. Hulling

The naturally dried coffee cherries are processed through hulling machines to remove the hard dried skin, pulp, and parchment layer, revealing the green beans.

Local Heirloom Varieties

The variety of FrontStreet Coffee's natural Guji is Ethiopia's local heirloom. They are called local heirlooms because Ethiopia has so many varieties—it's like a natural gene bank for Arabica. On one hand, there are numerous varieties making classification difficult, and on the other hand, the Ethiopian government,出于保护考虑, is unwilling to disclose information about these varieties. Therefore, they are collectively referred to as "Heirloom" varieties.

FrontStreet Coffee Natural Guji Coffee Bean Roasting Analysis

Set the roaster temperature to 175°C when loading the beans, with heat at 130 and damper at 3. The temperature return point is at 1'32". When the roaster temperature reaches 140°C, open the damper to 3.5 while keeping the heat unchanged. When the temperature reaches 155.6°C, the bean surface turns yellow, and the grassy aroma completely disappears, entering the dehydration stage. When the roaster temperature reaches 176°C, adjust the heat to 110 while keeping the damper unchanged.

At 7'28", ugly wrinkles and black spots appear on the bean surface, and the toasted bread aroma clearly transitions to coffee aroma—this can be defined as the prelude to first crack. At this point, listen carefully for the sound of first crack. First crack begins at 8'35", with the damper adjusted to 4. After first crack, develop for 1'45" and discharge at 195°C.

Agtron bean color value is 63.7 (left image), Agtron ground color value is 76.9 (right image), and Roast Delta value is 13.2.
