Introduction to Ethiopian Coffee, Flavor Characteristics of Ethiopian Sidamo Guji Coffee

The Evolution of Coffee Appreciation

In the past, people's pursuit of coffee might have been simply avoiding bitterness and acidity, seeking the familiar flavor profile of Blue Mountain coffee. However, as understanding of coffee deepened, people's expectations became increasingly sophisticated. particularly with the emergence of Ethiopian coffees, people discovered that coffee could possess such extraordinary flavors. As knowledge of coffee grows deeper, so does understanding of coffee culture and its rich heritage.

Ethiopia: The Birthplace of Coffee

There are many coffees in the world, but Ethiopia stands as coffee's birthplace, the genetic repository from which all coffee varieties originate. The mysterious legends surrounding coffee add to Ethiopia's captivating charm. Ethiopia is currently Africa's largest coffee-producing nation, yet only 60% of its coffee beans are exported, with the remainder used in various ceremonial contexts. For example, at weddings, people create medicinal mixtures using coffee beans and fruit pulp, coffee blended with honey, and various herbs to ward off misfortune. This demonstrates that coffee is an inseparable part of Ethiopian daily life. Among all coffee-producing countries, Ethiopia is perhaps the most remarkable. Ethiopian coffees, with their exuberant floral and fruity aromas, have opened many coffee professionals' eyes to the incredible diversity of coffee flavors.

Ethiopia's Climate

Ethiopia's climate is polarized: half consists of humid rainforests, while the other half is arid desert and Gobi terrain. Ethiopia's main rainy season spans June, July, and August, with coffee-growing regions receiving 1000-2000mm of annual rainfall and average temperatures between 15-30°C. Ethiopia boasts numerous high mountains that create tropical cloud forests, with coffee primarily cultivated on highland plateaus. The lower temperatures at high altitudes mean fewer pests, reducing the need for pesticides, while slower maturation allows coffee trees more time to absorb nutrients. Rainforests provide tall trees that shade coffee plants, with fallen leaves serving as protective mulch and nutrients, creating an ideal growing environment.

The Concept of Terroir in Ethiopian Coffee

Ethiopian coffees are typically named after their growing regions, and due to varying climates and environments, each region's coffee exhibits distinct characteristics, much like the concept of terroir in wine. The term "terroir" originated in the Cîteaux Abbey of Burgundy, France, where monks discovered through repeated experimentation that wines made from grapes grown in different plots produced different flavors. Therefore, terroir exists not only in the world of wine but is equally applicable to the world of coffee.

FrontStreet Coffee's Ethiopian Collection

Because of this diversity, FrontStreet Coffee has sourced dozens of different Ethiopian coffees from various regions to help coffee enthusiasts better understand and taste the flavors of coffee's birthplace. These include Yirgacheffe Red Cherry, Yirgacheffe Kochere, Sidamo Guji, Yirgacheffe Chaka, Washed Yirgacheffe, and Yirgacheffe Geisha Village Red Label and Gold Label, among others. Each region's coffee highlights its unique terroir. The most representative examples are the washed Yirgacheffe coffee and the natural processed Guji from Sidamo.

Ethiopian Coffee Cultivation Systems

Ethiopian coffee cultivation is divided into four main systems based on scale and mode:

Forest Coffee (8-10%)

Coffee trees coexist with other crops in natural forests without any artificial management. Farmers regularly harvest coffee cherries.

Semi-Forest Coffee (30-35%)

Coffee trees are planted in areas between forests and farmers' living areas. Like forest coffee, these are naturally occurring varieties, but farmers manage the growing areas and plant other economic crops.

Garden Coffee (50-55%)

Coffee trees are planted around farmers' residential areas, mostly self-cultivated by the farmers themselves.

Plantation Coffee (5-6%)

Large private growers with more processing facilities and production capacity.

Major Ethiopian Coffee Regions

Ethiopia has nine major coffee-growing regions: Yirgacheffe, Sidamo, Limu, Harrar, Jimma, Illubabor, Gimbi-Lekempti, Tepi-Bebeka, and Lake Tana. Among these, Yirgacheffe and Sidamo are the most famous, with each region containing numerous micro-regions.

Yirgacheffe (Specialty Region): 1,800-2,000 meters altitude (Garden coffee system)

Located northwest of Sidamo, Yirgacheffe was once part of the larger Sidamo region but became independent due to its outstanding flavor profile. To Ethiopia, Yirgacheffe is just a small town, but as a coffee region, Yirgacheffe encompasses more than just the town itself, including legal areas such as Wenago, Yirgacheffe town, Kochere, and Gelana Abaya.

Beyond being a coffee region, Yirgacheffe has become synonymous with a particular coffee flavor profile—bright and lively citrus acidity with distinctive delicate floral and fruit aromas. It represents specialty coffee and serves as an entry point for many into the world of premium coffee. Yirgacheffe is actually composed of surrounding coffee communities or cooperatives, including Idido, Harfusa, Hama, and Beloya near Misty Valley. While most are washed, some exceptional beans are intentionally natural processed to enhance their captivating fruity aromas and body.

Sidamo (Specialty Region): 1,400-2,200 meters altitude (Garden coffee system)

Currently, the most noteworthy coffee from Sidamo is arguably the Hambela Guji, with its wonderful strawberry cream flavor. This coffee made a stunning debut at the Ethiopian Taste of Harvest (TOH) competition in 2017, breaking Geisha's monopoly in brewing competitions and becoming the only coffee capable of challenging it.

Guji comes from Hambela, a sub-region under the Guji zone. Like Yirgacheffe, Guji was originally part of Sidamo but became independent due to its distinctive regional flavors. However, among coffee enthusiasts, Guji is still considered part of Sidamo. Currently, there are about 20 processing stations in Hambela, distributed across different villages and estates of varying sizes. Since coffee is an agricultural product and flavors vary annually, to distinguish between different year's flavors, the Guji name evolved from Guji 2.0, 3.0... to the current Guji 6.0.

Ethiopian Coffee Varieties

As coffee's birthplace, Ethiopia boasts an astonishing variety of local coffee cultivars. To date, nearly 2,000 varieties (1,927 indigenous and 128 introduced) have been recorded. This staggering number of varieties makes classification difficult, and the Ethiopian government has been reluctant to disclose detailed variety information for protection reasons, so they are collectively called "Heirloom varieties." Therefore, Ethiopian coffee beans commonly found on the market are all labeled as Heirloom varieties, and exported Ethiopian coffee beans are generally referred to as "local heirloom varieties."

Ethiopian Coffee Processing Methods

Ethiopia initially used the most traditional and primitive method for processing coffee beans: natural processing. However, in 1972, the Ethiopian government and growers introduced washed processing from Central and South America to improve bean quality and achieve better prices. Yirgacheffe, being Ethiopia's most water-rich region, particularly benefited from this method, which made its jasmine and citrus aromas clearer and brighter. This is why Yirgacheffe quickly became representative of world specialty coffee, and after the 1970s, this region focused primarily on washed processing, becoming Ethiopia's most prominent washed coffee region.

FrontStreet Coffee believes the fundamental difference between washed and natural processing is that washed processing presents coffee's most basic flavors, directly reflecting the special characteristics of each region, while natural processing adds sweetness and fermentation notes to this foundation.

Both natural and washed processing methods have their own merits. As Lorenzo Perkins, Education Director at Cuvée Coffee, says: "The delicate floral aromas and sweet fruit flavors that a washed Yirgacheffe can bring are unparalleled; or a natural processed Sidamo, sweet and bold—both are classic top-tier representatives of Ethiopian coffee."

FrontStreet Coffee's Brewing Parameters for Sidamo Guji

Since Sidamo Guji coffee is lightly roasted, the beans are quite hard and require 91°C hot water to extract their floral and fruity flavors. FrontStreet Coffee recommends a medium-fine grind (80% pass-through on China's #20 standard sieve). Too coarse a grind fails to extract body, resulting in thin coffee. Too fine a grind easily leads to over-extraction at high water temperatures, producing bitter coffee.

FrontStreet Coffee's specific brewing parameters are: V60 dripper, water temperature 91°C, water-to-coffee ratio 1:15, 15g coffee, medium-fine grind (80% pass-through on China's #20 standard sieve).

FrontStreet Coffee's staged extraction technique: First, use 30g water to fully saturate the coffee bed, forming a "hamburger" shape and bloom for 30 seconds. In the second stage, at 1:00, inject water to 125g, then wait for the water level to drop to 2/3 of the coffee bed before starting the third stage. In the third stage, at 1:40, inject water to 225g. Wait for the coffee to completely finish dripping, with total extraction time of 1:59. Total brewing time is 2:00. After extraction is complete, gently swirl the server to ensure the coffee is well mixed before tasting.

FrontStreet Coffee's Brewing Suggestions

To brew a delicious cup of coffee, attention to coffee bean freshness is essential. FrontStreet Coffee has always believed that coffee bean freshness greatly affects flavor, so FrontStreet Coffee ships all coffee beans within 5 days of roasting. FrontStreet Coffee's roasting philosophy is "Freshly Roasted Good Coffee," ensuring every customer receives the freshest coffee possible. The coffee degassing period is about 4-7 days, so when customers receive their coffee, it's at peak flavor.

For friends who need ground coffee, FrontStreet Coffee offers a gentle reminder: pre-ground coffee doesn't need additional degassing time, because the pressure from carbon dioxide buildup in the package during transport helps mellow the coffee flavor. Therefore, you can brew a cup immediately upon receiving ground coffee. However, ground coffee should be brewed promptly, as it oxidizes quickly when exposed to air, meaning its flavor dissipates rapidly and won't be as good. Therefore, FrontStreet Coffee recommends purchasing whole beans and grinding fresh before brewing to better experience the coffee's flavor.

Ethiopian coffee's floral and fruity notes are remarkably light and leave an endless aftertaste, making one feel it's less like a cup of coffee and more like a cup of fruit tea.
