How Do Ethiopian Coffee Processing Methods Compare Across Africa?

Africa is the birthplace of coffee and still grows a wide range of it. Ethiopia and Kenya anchor the continent's output, and both are known for intense aroma and fruity acidity. Ethiopia alone has nine major specialty regions, Kenya has six, and countries such as Burundi, Rwanda, Tanzania, and Malawi add their own profiles. Much of the high-quality Arabica comes from the eastern belt running from Ethiopia and Kenya to Rwanda.

Processing and variety differ sharply by country and even by region, which is why African beans show such range in the cup. West African countries including Senegal and Cameroon, by contrast, are dominated by Robusta. In some places coffee still grows wild, a reminder of how long the crop has existed there. Ethiopian coffee processing methods and Kenyan washed lots illustrate how much technique shapes the final flavor.

Africa, as the birthplace of coffee, is home to many renowned producing countries such as Ethiopia and Kenya, and is celebrated for its rich aromas and alluring fruity acidity. This article systematically reviews the variety distribution, cultivation patterns, processing methods, and flavor characteristics of African coffee, with a focus on Ethiopia's nine major specialty regions, Kenya's six major regions, and the coffee features of Burundi, Rwanda, Tanzania, and other countries. It also retains Front Street Coffee's detailed brewing suggestions and flavor descriptions for beans such as Yirgacheffe, Huakui, Kenya Little Tomato, Rwanda Gaseke, and Tanzania Kilimanjaro, providing a comprehensive reference for coffee enthusiasts.

Friends who have visited the FrontStreet Coffee physical store will notice that in the column listing bean names on the menu, African-origin coffees always take the lead. This is not because Front Street shows any favoritism toward Africa—it is simply that African beans are incredibly diverse, and each country has its own distinctive flavor, with subtle differences even between regions.

Africa straddles the equator and occupies an extremely prominent position in the global coffee landscape. Among them, Ethiopia and Kenya stand out in particular, serving as the two pillars of African coffee. Should either one encounter problems, it would deliver an incalculable blow to the entire African coffee industry. That is why the coffees of these two countries are highly regarded across the global industry and boast legions of fans. Of course, African coffee cannot rely on just these two countries alone—there is much more worth exploring!

Many of Africa's high-quality coffee beans come from the eastern belt stretching from Ethiopia and Kenya to Rwanda, where high-quality Arabica coffee is grown; while West African countries such as Senegal and Cameroon are dominated by Robusta. This article will briefly introduce several major regions: Ethiopia, Uganda, Kenya, Tanzania, and Malawi. To be fair, coffee cultivation on the African continent is extremely widespread, and in many places the coffee even grows wild.

[Flavor Characteristics: Fascinating Fruity Acidity]

As the birthplace of coffee, Africa holds a prominent position in the entire industry. Although commercial cultivation has developed over centuries, Africa still retains a large number of wild coffee varieties, making it a treasure that researchers have always cherished most. African coffee is generally known for its rich aromas and alluring fruity acidity—lively, bright, and invigorating—but its body is usually on the thinner side, and its sweetness is not particularly pronounced. Due to arid climates and scarce water, Africa predominantly uses the natural (dry) process for green beans, and the beans are often irregular in shape with a relatively high defect rate.

[Ethiopia]

Ethiopia has three major coffee-producing regions: Harrar, Ghimbi, and Sidamo (or Yirgacheffe). Harrar beans come from smallholder farmers, are dry-processed, and are classified by size into "longberry" and "shortberry," as well as the round-bean Mocha.

[Coffee Cultivation in Ethiopia]

Around 1995, Ethiopia adjusted its administrative divisions. The change with the greatest impact on coffee regions was the splitting of the former Sidamo Province: a small portion became the new Sidama, while the majority was incorporated into Oromia State; Yirgacheffe, formerly part of Sidamo Province, is now part of the new Gedeo Zone. Currently, Ethiopian coffee names circulating in the market mix old and new regional names. Here, we use the new divisions as our basis and combine them with administrative regions to understand Ethiopia's coffee cultivation landscape.

Ethiopia's coffee cultivation is concentrated in the west and south. Smallholder families account for 90% of all growers, with nearly 1.2 million smallholder families depending on coffee for their livelihoods. Each household cultivates less than 4 hectares, at elevations averaging between 1,000 and 2,300 meters, with a planting density of 1,000 to 1,800 trees per hectare and a yield of approximately 600 kilograms per hectare.

By scale and model, Ethiopian coffee cultivation is divided into:

● Forest coffee (8-10%): Coffee trees coexist with other crops in primary forests, with no artificial management; farmers periodically harvest coffee cherries

● Semi-forest coffee (30-35%): Plantation areas lie between forests and farmers' living areas; coffee trees grow naturally, and farmers manage the plantation areas and cultivate other cash crops

● Garden coffee (50-55%): Coffee trees are planted around farmers' living areas, mostly planted by the farmers themselves

● Plantation coffee (5-6%): Large private growers with more processing facilities and capacity

[Ethiopian Coffee Varieties]

Ethiopia has nearly 2,000 recorded coffee varieties (of which 1,927 are native varieties and 128 are introduced varieties).

In terms of appearance, Ethiopian coffee varieties are truly a "grand garden"—long, short, thin, plump, there's everything you could imagine...

[The Complete Family Tree of Ethiopian Native Varieties]

Long-shaped beans: Distributed throughout all coffee-growing areas in Ethiopia. In terms of actual proportions, the western Jimma region (including Limmu and Kaffa) has more long-shaped varieties, while Sidama and Yirgacheffe have fewer.

Small-bean varieties: Rounder in appearance with very small bean size, mostly between screen sizes 14-15. This is the variety most familiar to everyone, often seen in Sidama and Yirgacheffe, and also found in Harrar samples and green beans sold locally in Jimma. Compared to other regions, Sidama, Yirgacheffe, and the surrounding Arsi and Guji areas grow more of these small-bean native varieties.

[Processing Methods]

Ethiopian coffee processing methods include:

● Natural (sun-dried): The most traditional processing method. The Harrar region is particularly arid, with no water source for washing, so all coffee is naturally processed; other regions such as Sidama, Yirgacheffe, Guji, and Jimma also produce natural-processed coffee

● Washed: Requires higher standards for processing equipment, water sources, and processing plant environments, but can consistently produce high-quality coffee in large quantities. All regions except Harrar have washed processing

● Honey process: In the past two years, items labeled as Kochere honey process have appeared on the market; this is noted with reservation for now

[Flavor Characteristics]

● Washed: Citrus fruit flavors, similar to lemon, mandarin, orange, grapefruit, sweet pomelo. Flavor intensity ranges from pronounced citrus fruit (peel) aromas, to varying intensities of fruity acidity, from soft little mandarins, to medium-intensity oranges, to the more refreshing acidity of lemon and grapefruit.

● Natural: Ripe yellow, red, and black fruit aromas, similar to apricot, peach, cherry, strawberry, cranberry (dried), blueberry (dried), plum, etc., accompanied by varying degrees of vinous notes resembling rum, whiskey, or even red wine (Beaujolais).

[Ethiopian Coffee Grades]

The grade definitions for Ethiopian coffee are relatively complex.

According to Front Street's research, the Cupping and Liquoring Unit (CLU) under Ethiopia's Ministry of Agriculture is responsible for quality approval of export coffee, which includes the important duty of grade definition; the CLU existed before the ECX.

Before the ECX existed, export grades for washed coffee were divided into G1 and G2; export grades for natural coffee were G3, G4, and G5, meaning the highest grade for natural coffee was G3.

After the ECX was established, grading was redefined: washed grade names remained unchanged, while G1 appeared for natural coffee for the first time. This is why the market now has Ethiopian natural G1 and G2, while G3 is gradually decreasing.

The Front Street Ethiopian coffees available at FrontStreet Coffee are all G1 grade.

[Ethiopia's Nine Major Specialty Regions]

Yirgacheffe (Specialty Region): Elevation 1,800–2,000m | Garden Coffee System |

Yirgacheffe belongs to the Sidamo producing region but was separated out due to its unique flavor. In addition to Yirgacheffe town itself, it also includes three sub-regions: Wenago, Kochere, and Gelena/Abaya. Therefore, under the new grading system, Yirgacheffe A, Wenago A, Kochere A, and Gelena/Abaya A are more expensive than their B counterparts. Beyond washed and natural, specialty-processed beans have also appeared in the Yirgacheffe region in recent years. In FrontStreet Coffee's Front Street Daily series, there is a washed Yirgacheffe with a clean mouthfeel, intense white floral aroma, and a strong sweet finish—even Front Street's baristas can't get enough of it.

Sidamo (Specialty Region): Elevation 1,400–2,200m | Garden Coffee System |

Flavor is similar to Yirgacheffe. Finely washed or natural Sidamo also has floral and orange notes, and its value is no less than Yirgacheffe's. The two regions have similar varieties—medium-sized beans but also short, small-bean varieties, which farmers often sell separately. The common Kurmie has poor disease resistance; Wolisho is tall and robust; Deiga has a medium tree shape. These three are the mainstay of the Biloya and Aricha series in specialty natural coffees. Front Street Huakui comes from the Sidamo region and, besides pronounced floral notes, also possesses Sidamo's wild berry acidity, making it deeply beloved.

Limu (Specialty Region): Elevation 1,200–2,000m | Garden, Forest, Semi-forest, and Plantation Coffee Systems |

Production is relatively small, mainly exported to European and American markets. It is not easy to find in Taiwan, but it is very popular in Europe and America. It has three processing methods: washed, natural, and semi-washed. Limu has noticeably lower viscosity, and its floral and citrus notes are inferior to Yirgacheffe and Sidamo, but it has an added grassy aroma and brown sugar sweetness, with bright fruity acidity.

Harrar (Specialty Region): Elevation 1,500–2,400m | Garden Coffee System |

Harrar is exclusively natural-processed. It is an ancient city in the east, but coffee is not grown within the city itself—so-called Harrar coffee refers to coffee produced in the highlands and lowlands of the greater Harrar area. Annual rainfall is only 1,000mm, and all coffee is naturally processed. In terms of flavor, Harrar is famous for its unique "wild mixed aroma," a classic example of ancient early flavors, and is known alongside Yirgacheffe as the "Twin Stars."

If the defective beans in Harrar can be sorted out cleanly, it is easy to taste berry notes with a pleasant fermented wild aroma. However, due to various factors, Harrar coffee quality has been unstable in recent years, and the grading system is also unreliable. When purchasing, be sure to cup or taste before buying.

Jimma (Large-scale Commercial Bean Region): Elevation 1,350–1,850m | Forest/Semi-forest System |

Jimma is the capital of the Kaffa forest or Kaffa Province. The English spelling is quite inconsistent—most maps use "Jimma," but coffee burlap bags spell it "Djimmah." This is Ethiopia's largest producing region, accounting for one-third of exports.

The Kaffa forest is known for its primitive wild varieties. Jimma is the collection and distribution center for Kaffa in this region. Farmers habitually transport coffee picked from the forest to Jimma, where hundreds if not thousands of varieties are mixed together and sold as commercial beans, masking the aromas of many delicious varieties.

Although washed specialty Jimma lacks the orange and floral notes of Yirgacheffe, its flavor profile is clean and translucent, similar to Central American specialty coffees. Commercial-grade specialty Jimma is very common in Taiwan; with luck, you can buy good-quality Jimma at a reasonable price and taste lemon peel freshness that rivals Sidamo. Overall, Jimma has better flavor than Brazil's large-scale commercial Santos and is a great mid-to-low-priced blend bean.

Illubabor (Large-scale Commercial Bean Region): Elevation 1,350–1,850m | Forest/Semi-forest Coffee System |

This region is located in western Ethiopia, bordering Sudan, and is the westernmost producing region. Its coffee genetic diversity is second only to the Kaffa forest. The beans are noticeably larger than Yirgacheffe and Sidamo, with lower fruity acidity, good viscosity, and balanced flavor. Coffee from here is mostly transported to Jimma for blending and is rarely sold independently.

Gimbi, Lekempti (Large-scale Commercial Bean Region): Elevation 1,500–1,800m | Forest/Semi-forest Coffee System |

This region has both natural and washed beans. The beans resemble Harrar's longberry, and a small amount of specialty-grade coffee is also well-received in Europe and America. Most is praised as "the poor man's Harrar," with better fruity acidity and fruit flavors than Illubabor, and a bright flavor profile.

Tepi, Bebeka (Large-scale Commercial Bean Region): Elevation 500–1,900m | Garden/Forest/Semi-forest Coffee System |

The two producing regions are very close, with Tepi to the north of Bebeka. There is an enterprise-managed coffee plantation, and in recent years garden systems have been promoted to increase farmer income, with annual production of about 3,000 tons. Both areas have wild coffee, with low yields. The flavor is very different from Harrar and Yirgacheffe, with low fruity acidity being the biggest characteristic. Suitable for blend beans, available in both natural and washed.

Lake Tana Area (Alternative Region): Elevation 1,840m | Forest System |

Monastery coffee. The surrounding forest coffee has extremely low annual production—less than 10 tons—so it can hardly be called a producing region. The Orthodox monasteries, churches, religious murals, and myths that dot the lake area have created the world's most "divine" coffee.

European monastery monks pioneered the local coffee cultivation industry, which was later taken over by coffee communities or cooperatives in villages around the town. There are no dedicated plantations here; coffee trees are naturally scattered throughout forests and gardens. During harvest season, the Ethiopian Coffee Trading Company comes to town to purchase coffee beans collected by farmers.

[Burundi]

Burundi (The Republic of Burundi) is located in east-central Africa, south of the equator. It borders Rwanda to the north, Tanzania to the east and south, the Democratic Republic of the Congo to the west, and Lake Tanganyika to the southwest. The country is dominated by plateaus and mountains, mostly formed by the highlands on the eastern side of the East African Rift. The national average elevation is 1,600 meters, earning it the name "Land of Mountains." Burundi is mountainous, and its elevation and climate are highly suitable for coffee cultivation. FrontStreet Coffee noticed from maps that its nickname "Heart of Africa" is well deserved—its territory is shaped like a heart.

Burundi coffee beans are mainly produced by numerous smallholder farmers, mostly concentrated around processing stations within the country. The wet-processing stations in different producing regions also have their own management and integration units (abbreviated as SOGESTAL), essentially wet-processing station management associations. The main function of these associations is to provide better hardware and equipment for their areas, and they have contributed greatly to the improvement of Burundi coffee quality in recent years. Burundi's best coffees are washed and mostly Bourbon varieties.

Burundi has one of the world's most diverse and successful coffee industries, with its own distinctive characteristics. Coffee was introduced to the country in 1930 by Belgian colonists and is now grown only on small farms. Unfortunately, many farms are located in areas bordering war-torn Rwanda, putting pressure on coffee production. Almost all coffee produced in Burundi is Arabica, with coffee trees in Ngozi planted at elevations above 1,200 meters. Burundi coffee has a rich, aromatic flavor and excellent acidity, with most products exported to the United States, Germany, Finland, and Japan.

Burundi coffee bears a striking resemblance to that of its neighbor Rwanda, and the coffees from the two countries are often confused. Burundi is predominantly Bourbon, using traditional washed processing of coffee cherries. The main characteristics of its specialty coffee are elegant sweetness and bright citrus aromas.

Flavor Description: Fresh aromas of kumquat and lemon; caramel and plum sweetness fill the entire cup; the fermented acidity of the washed process is very bright.

[Kenya: Small Cooperatives]

Kenyan coffee has pronounced acidity, sweetness, and a dry vinous finish, with the most outstanding being the flavor and aroma of blackcurrant. Auctions are held every Tuesday during harvest season in Nairobi, sparking bidding wars for the best crops. In recent years, Kenyan green bean prices have been high and prone to disappointment. Front Street's roasters and baristas often work overtime roasting and cupping newly arrived Front Street Kenyan coffees, all to present a cup of Kenyan coffee with clean and beautiful acidity.

[Kenya's 6 Major Regions]

Nyeri and Murang'a

The bright acidity and full body that most people love are both found here. Plus, being not far from Nairobi, many foreign buyers visit during the harvest season.

Nyeri

Bright blackberry and rich oils, plus citrus and even floral notes—the specialty beans here are a major contributor to Kenya's international fame.

Kirinyaga

The flavor also features bright fruity acidity, with medium oiliness and delicate sweetness.

Embu

The acidity here is not as intense as Nyeri's; the flavor is balanced and clear, and the finish is mostly excellent.

Machakos

This region is on the rise. Known for clean fruity acidity, delicate flavors, medium body, and a delicate, fresh finish, it has attracted many buyers in recent years.

Western Region

The flavor is very different from the central regions, attracting buyers with medium-full sweetness and milder flavors. Some washing stations in this area lean toward hazelnut and mild fruit notes, also widely favored by buyers who dislike bright acidity.

Kenyan coffee is mostly produced by small cooperatives rather than large estates, wet-processed, and graded by bean size. Kenyan coffee has high acidity (with vivid aromatic notes) and a bright mouthfeel. Depending on which farm it comes from, it has berry or citrus flavors, sometimes alternating with spice. Some are bright and clean, while others carry vinous notes.

Kenya developed a disease-resistant hybrid called Ruiru 11, but it lacks some of the best flavor characteristics of traditional coffee and is considered a lower grade. They are still improving this bean, hoping it can taste as good as natural crops.

Malawi is a small country in southeastern Africa between Mozambique and Zambia. Its coffee has a smooth, full mouthfeel—a true tactile experience. It rarely reaches the Western Hemisphere, so if you see some, you should seize the opportunity to taste it. You will find a softer, more floral, sweet, delicate, and bright East African style.

[Rwanda: Land of a Thousand Hills]

Rwanda (Republika y'u Rwanda) is a landlocked country in east-central Africa, located south of the equator. It borders Tanzania to the east, Burundi to the south, the Democratic Republic of the Congo to the west and northwest, and Uganda to the north, with a total area of 26,338 square kilometers. Most of the country has a tropical highland climate and tropical savanna climate, mild and cool, with an average annual temperature of 18°C. The year is divided into two dry seasons and two rainy seasons: March to May is the long rainy season, and October to December is the short rainy season, with average annual precipitation of 1,000–1,400mm.

Rwanda Coffee and Geography

The country is dominated by mountains and plateaus, with over 1,800 hills of various sizes, earning it the name "Land of a Thousand Hills." The east has many hills, marshes, lakes, and a dense water network, along with vast natural pastures; the central area is lakeside lowland; the northwest is volcanic. Rwanda is the closest to the equator, but its elevation is above 1,500 meters, with an average annual temperature of only 18°C. Combined with abundant rainfall and suitable hydrothermal conditions, the picturesque scenery has earned it the names "Land of Eternal Spring" and "Switzerland of Africa."

The beautiful Land of a Thousand Hills, Rwanda, has a long and rich culture of growing highland coffee, primarily high-quality Arabica. Rwanda's specialty coffee accounts for 20% of total coffee production and is very popular in international markets. This unique growing environment gives Rwanda's high-quality coffee a distinctive taste and aroma. Because of these distinctive flavors, Front Street acquired a bean from Rwanda, hoping to share the tasting experience with everyone.

According to Front Street's source, Karuritwa—Marketing and Promotion Officer at the Rwanda Coffee Association—stated that Rwanda plans to reach 3,000 tons of coffee exports this year, further increasing production to meet growing market demand. Starbucks, the world's largest coffee beverage retail company, has also partnered with the Rwandan government to import Rwandan coffee. As shown on Rwanda's coffee trademark, a coffee-colored dove rises from a coffee cup, set against the words "Cup of Hope."

Rwanda coffee's taste is described as "grassy aroma" with tropical climate characteristics. Through cupping, Front Street found that besides fruity sweetness, this coffee also offers a refreshing, bright, and fresh sensation. The Bourbon coffee grown in Rwanda is stunning for its fruity sweetness, with a rich and full aroma that is never astringent and has a long finish. This coffee has a pleasant citrus sweetness, a deep chocolate color, and notes of red apple, cherry, cinnamon, and honey, with excellent sweetness and balance, and a finish of cinnamon, almond, and chocolate.

[Tanzania]

Tanzania is one of the birthplaces of ancient humans. It had trade contacts with Arabia, Persia, and India as early as before the Common Era. Tanzania's full name is The United Republic of Tanzania, located in East Africa south of the equator, and a member of the Commonwealth. It borders Kenya and Uganda to the north, Zambia, Malawi, and Mozambique to the south, Rwanda, Burundi, and the Democratic Republic of the Congo to the west, and the Indian Ocean to the east. FrontStreet Coffee's bean list also includes a bean from Tanzania.

Tanzania has a total area of 945,087 square kilometers, of which Zanzibar accounts for 2,657 square kilometers. It consists of the mainland, Zanzibar Island, and more than 20 small islands. Located in East Africa south of the equator, the mainland borders the Indian Ocean to the east, Zambia, Malawi, and Mozambique to the south, Rwanda, Burundi, and the Democratic Republic of the Congo to the west, and Kenya and Uganda to the north. The mainland coastline is 840 kilometers long. The terrain is high in the northwest and low in the southeast, forming a stepped landscape. The eastern coast is lowland; the western inland plateau accounts for more than half of the total inland area; and the East African Rift Valley runs north-south through the country in two branches from Lake Malawi. In the northeast, the Kibo Peak of Mount Kilimanjaro stands at 5,895 meters, the highest peak in Africa.

Unlike most African producing countries, Tanzania's coffee bags are not the common jute bags but rough fiber bags made from sisal leaves. This is because the local government banned jute bags to protect the sisal industry.

| Cultivated Varieties

According to Front Street's information, the most commonly grown coffee varieties in Tanzania are Bourbon, Typica, and Kent.

Bourbon

What is generally called Bourbon usually refers to Red Bourbon. After the Red Bourbon coffee tree flowers and bears fruit, the cherry color changes as follows: green → slightly yellow → slightly orange → ripe red → overripe dark red, which is why some call it Red Bourbon. High-elevation Bourbon typically has better aroma, bright acidity, and can even taste similar to red wine.

Typica

Excellent flavor expression; recognized as a specialty coffee variety, but with extremely low yield and susceptibility to rust disease, requiring more labor for management. Typica originated in Ethiopia and southeastern Sudan and is the most widely cultivated coffee variety in the Western Hemisphere. The plant is relatively robust but not tolerant of strong sunlight. Typica's top leaves are copper-red, hence the name "Red Top Coffee."

Kent

A Typica hybrid variety discovered in 1911 at the Kent coffee estate in Mysore, India. It was created by crossing S288 with Typica and has high yield and rust resistance. Its coffee aroma is heavier and more substantial than Bourbon, and it has been introduced to Kenya, Indonesia, and other New World producing countries, making significant contributions.

| Processing Methods

Tanzanian green beans are primarily washed. The washed method is currently the most widely used processing method, using washing and fermentation to remove the fruit skin, pulp, and mucilage. Washed method: sorting → depulping → fermentation → washing → drying → hulling → sorting and grading.

| Grading

Tanzania's grading method is the same as Kenya's, grading by bean size and flavor. Bean sizes in order:

AA Plus (AA+): AA grade with particularly excellent cup quality (flavor, mouthfeel) AA: Screen Size 17–18 AB: Screen Size 15–16, accounting for the majority of production C: Smaller than AB in screen size TT: Lighter beans blown out from AA and AB grade beans by airflow separator T: Lighter beans blown out from C grade beans by airflow separator E Elephant Bean: Large mutant beans formed by two beans fused together, also called Elephant ear UG: Does not meet the above standards PB Peaberry: Classified by appearance, unrelated to flavor or weight

Coffee Mouthfeel:

Tanzania is a typical East African country, bordering Kenya and Uganda to the north, Malawi, Mozambique, and Zambia to the south, and Rwanda and Burundi to the west. Many people like to compare Tanzanian coffee with its neighbor Kenya. Compared to high-quality Kenyan beans, Tanzanian coffee has slightly less bright acidity, is softer and gentler, with more sweet aroma, and a pronounced vinous character is also one of its features.

In northeastern Tanzania stands Africa's highest peak, Mount Kilimanjaro. After World War I it was a mandated territory under British colonial rule, gaining independence in 1964. Bourbon coffee was first introduced for cultivation in 1893. Green bean processing is primarily washed, and high-quality high-elevation Tanzanian coffee has active, bright acidity similar to Kenya's.

Tanzania's northern coffee-producing regions include Moshi and Mbeya around the foothills of Mount Kilimanjaro. To the south, the main area is the Songea-Ruvuma region through which the Ruvuma River flows. Due to different growing terrain, the styles differ slightly. Coffee from the southwestern Ruvuma region has vinous and fruity aromas, different from coffee from the northern areas near Mount Kilimanjaro.

Mount Kilimanjaro is in northeastern Tanzania and is also Tanzania's largest coffee-producing region, accounting for 75%. Generally speaking, Tanzanian coffee beans have exceptional quality. Important producing areas are in the northern mountainous areas near Kenya, where smallholder farmers account for 85% of cultivation. Local smallholder coffee is grown at elevations between 1,300–2,000m. The coffee flavor is distinct from neighboring Ethiopia and Kenya, combining characteristics of both countries—good body with both fruity and floral aromas. It's worth trying. Coffee belongs to dicotyledonous plants. Generally, a single coffee cherry normally contains a pair (i.e., two halves) of coffee seeds, which is what we call coffee beans.

Compared to flat beans (pair of flat-sided beans), the round bean also called caracol or caracolillo—its Spanish meaning is "little snail." Botanically, the production of peaberries is said to be due to uneven pollination (Arabica coffee is a self-pollinating plant; if a coffee flower has only one ovary, or only one ovary is successfully pollinated, only one seed can be produced), or uneven nutrition during growth (usually more likely to occur in coffee cherries growing on the terminal branches of the coffee tree), where nutrients are absorbed by only one of the two cotyledons. The cotyledon that receives nutrients grows into a single oval-shaped coffee seed, hence the name peaberry. Normally, the proportion of peaberries produced by coffee plants is about 3 to 5%, making production relatively scarce. Also, because the shape and size differ from normal flat beans, peaberries are often separately graded and sold through mesh screening.

Northern coffee is full of aroma, with bright acidity and a full body. Thanks to fertile volcanic soil, it carries a mineral water-like sweetness.

Southern coffee has rich floral notes, a smooth mouthfeel, and elegant fruity acidity.

Coffee-growing regions in Africa—Tanzanian coffee comes from the fertile soil of the East African Rift Valley and is an outstanding representative of high-quality coffee from this region. Its refreshing acidity and medium body complement sweet citrus and floral aromas. This coffee tastes excellent whether served hot or as iced coffee. Paired with orange or berries, its bright flavors are even more pronounced. A bean from Tanzania Kilimanjaro that Front Street acquired is no exception.
