Which processing methods shape Ethiopian and Kenyan coffee?

Ethiopia and Kenya anchor African coffee, and their cup profiles rest on local cultivation systems, varieties, and processing choices. Coffee mostly comes from eastern Africa, where high-quality Arabica beans are grown, from Ethiopia and Kenya through Rwanda, while West African countries such as Senegal and Cameroon lean toward Robusta.

Ethiopia and Kenya are treated as the two pillars of the continent, and each producing country, and even each region within it, carries a distinct flavor personality. Burundi, Rwanda, Tanzania, Uganda, and Malawi add further diversity, which is why African origins often fill the first column of a roaster's menu of Arabica beans.

Africa, as the continent of origin for coffee, has given rise to many exceptional bean varieties that captivate coffee lovers worldwide. Among them, Ethiopia and Kenya stand as the two pillars of African coffee, earning widespread recognition for their distinctive flavor profiles. This article systematically examines the cultivation systems, varietal composition, processing methods, and flavor expressions of major African coffee-producing countries—including Ethiopia, Burundi, Rwanda, Kenya, and Tanzania—offering in-depth analysis of the subtle differences among specialty regions, while also introducing the roasting and brewing parameters for several African beans from Front Street Coffee, providing coffee enthusiasts with a complete guide to African coffee flavors.

Those who have visited a Front Street Coffee physical store will notice that the first column listing bean names on the menu always belongs to African origins. This is not because Front Street deliberately favors Africa, but rather because African coffee beans are extraordinarily diverse, with each producing country possessing a unique flavor personality, and even within the same country, subtle differences exist between different regions.

Africa straddles the equator and occupies a pivotal position among global coffee-producing regions. Ethiopia and Kenya are the two most renowned producing countries in the region, serving as the two pillars of African coffee—the decline of either would deliver an incalculable blow to the entire African coffee industry. The coffee of these two nations has long earned global industry recognition and commands a large following. Of course, Africa's coffee landscape extends far beyond these two countries, with many more worth exploring.

Africa's finest coffee beans mostly come from the eastern region, stretching from Ethiopia and Kenya to Rwanda, where high-quality Arabica beans are produced. West African countries such as Senegal and Cameroon, by contrast, are dominated by Robusta. This article will briefly introduce producing regions including Ethiopia, Uganda, Kenya, Tanzania, and Malawi. Objectively speaking, coffee cultivation across the African continent is extremely widespread, with wild coffee even existing in many areas.

[Flavor Profile: Alluring Fruit Acidity]

As the birthplace of coffee, Africa occupies an irreplaceable position in the global coffee industry. Although commercial cultivation has spanned centuries, Africa still preserves an enormous number of wild coffee varieties—resources that remain the most valuable treasure trove in the eyes of coffee researchers. The common characteristics of African coffee are intense aroma and alluring fruit acidity—bright, lively, and invigorating—though the body tends to be thin and sweetness insufficiently pronounced. Due to arid climates and water scarcity, African coffee often uses the natural (dry) process for green beans, resulting in frequently uneven bean shapes, irregular appearance, and a relatively higher defect rate.

[Ethiopia]

Administratively, coffee is grown in all five major regions of Ethiopia, with four cultivation systems covering the following nine major producing areas: Jimma, Sidamo, Yirgacheffe, Harrar, Limu, Illubabor, Gimbi (Lekempti), Teppi, and Bebeka. Among these, Yirgacheffe, Harrar, and Sidamo are the three most widely known names.

[Coffee Cultivation in Ethiopia]

Around 1995, Ethiopia adjusted its administrative boundaries. The change with the greatest impact on coffee-producing regions was the splitting of the former Sidamo Province—a small portion was retained as the new Sidama, while the majority was incorporated into Oromia State. Meanwhile, Yirgacheffe, formerly part of Sidamo Province, is now assigned to the new Gedeo Zone. As a result, Ethiopian coffee circulating on the market is named using both old and new region names, creating a rather confusing situation. The following uses the new administrative divisions as the basis for outlining Ethiopia's coffee cultivation landscape.

Ethiopia's coffee cultivation is mainly concentrated in the west and south, with smallholder family operations accounting for 90% of total cultivation. Approximately 1.2 million smallholder families make their living from coffee, each cultivating less than 4 hectares, at elevations ranging from 1,000 to 2,300 meters, with a planting density of 1,000 to 1,800 coffee trees per hectare and a yield of about 600 kilograms per hectare.

By scale and model, Ethiopian coffee cultivation can be categorized as:

● Forest coffee (8-10%): Coffee trees grow symbiotically with other crops in primary forest without human intervention; farmers harvest the cherries periodically

● Semi-forest coffee (30-35%): Plantations are located between forest and farmer living areas; coffee trees grow naturally like forest coffee, but farmers manage the plantation area and cultivate other cash crops

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

● Plantation coffee (5-6%): Operated by large private growers with more complete 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"—shapes vary widely, with every combination of length, shortness, plumpness, and leanness imaginable.

[The Full Family Tree of Ethiopian Native Varieties]

Long-shaped beans: Distributed across 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 lower proportions.

Small-bean varieties: Relatively round in shape with very small bean size, mostly between 14 and 15 screen sizes. This variety is the most familiar to everyone and is frequently seen in Sidama and Yirgacheffe. The author has also seen it in Harrar samples and green coffee beans sold locally in Jimma. Compared to other regions, Sidama, Yirgacheffe, and the surrounding Arsi and Guji areas cultivate more of these small-bean native varieties.

[Processing Methods]

Ethiopian coffee processing methods include:

● Natural (dry) process: The most traditional processing method. The Harrar region, due to extreme aridity and lack of water sources for washing, uses entirely natural processing. Other regions such as Sidama, Yirgacheffe, Guji, and Jimma also produce natural-process beans.

● Washed process: Compared to natural, it demands higher standards for processing equipment, water sources, and facility environment, but can more consistently produce high-quality coffee in volume. All producing regions except Harrar use washed processing.

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

[Flavor Characteristics]

● Washed: Citrus fruit profile, similar to lemon, tangerine, orange, grapefruit, sweet pomelo. Flavor intensity ranges from pronounced citrus peel aroma to varying degrees of fruit acidity—from soft tangerine to medium-intensity orange, to crisp lemon and grapefruit acidity.

● Natural: Ripe yellow, red, and black fruit aromas, such as 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) character.

[Ethiopian Coffee Grades]

The grading definitions for Ethiopian coffee are relatively complex.

Through research, Front Street learned that under the Ethiopian Ministry of Agriculture there is a department called the Cupping and Liquoring Unit (CLU), specifically responsible for quality approval of export coffee, with grade definition being a very important responsibility. The CLU existed before the ECX was established.

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

After the ECX appeared, grading was redefined. Washed grade names remained unchanged, while G1 appeared for the first time for natural coffee. This is why Ethiopian natural G1 and G2 can now be seen on the market, while G3 is gradually decreasing.

Front Street Ethiopia coffees sold by Front Street Coffee are all G1 grade.

[Ethiopia's Nine Major Specialty Producing Regions]

Yirgacheffe (specialty region): Elevation 1,800–2,000m | Garden coffee system |

Yirgacheffe is attached to the Sidamo producing region but was separated out due to its unique flavor. In addition to Yirgacheffe town, it also includes three sub-regions: Wenago, Kochere, and Gelena/Abaya. Therefore, in the new Yirgacheffe grading system, Yirgacheffe A, Wenago A, Kochere A, and Gelena/Abaya A command higher prices than their B-grade counterparts. Besides washed and natural, specialty processing method beans are now also appearing in the Yirgacheffe region. In Front Street Coffee's daily drinking series, there is a washed Yirgacheffe with a clean mouthfeel, intense white floral notes, and a strong sweet finish—even Front Street's baristas are enamored with it.

Sidamo (specialty region): Elevation 1,400–2,200m | Garden coffee system |

Flavor is similar to Yirgacheffe. Finely washed or natural Sidamo also carries floral and citrus notes, with a reputation no less than Yirgacheffe. The two regions share similar varieties—medium-sized beans, as well as dwarf small-bean varieties that farmers often sell separately. The common Kurmie has poor disease resistance; Wolisho is tall and robust; Deiga has a medium tree shape—these three varieties are the mainstays of the Biloya and Aricha series in specialty natural coffee. Front Street's Huakui comes from the Sidamo region; besides obvious floral notes, it carries the region's signature wild berry acidity, making it highly popular.

Limu (specialty region): Elevation 1,200–2,000m | Garden, forest, semi-forest, and plantation coffee systems |

Production is relatively small, mainly sold to European and American markets; not easily available in Taiwan but quite popular in Europe and America. There are three processing methods: washed, natural, and semi-washed. Limu's body is noticeably thin, and its floral and citrus flavors are inferior to Yirgacheffe and Sidamo, but it has an added grassy and brown sugar aroma with bright fruit acidity.

Harrar (specialty region): Elevation 1,500–2,400m | Garden coffee system |

Harrar exclusively uses natural processing. It is an ancient eastern city, though coffee is not grown within the city itself. So-called Harrar coffee refers to coffee produced in the high and low areas of Hararghe in the greater Harrar region. Annual rainfall is only 1,000mm, and all coffee uses natural processing. In terms of flavor, Harrar is famous for its unique "wild complexity," a typical representative of ancient early flavors, and is called one of the "Twin Stars" alongside Yirgacheffe.

If Harrar's defective beans can be properly sorted out, it's easy to taste berry notes with a slightly pleasant fermented complexity. However, affected by various factors, Harrar coffee quality has been unstable in recent years, and the grading system is not entirely reliable—be sure to cup or taste before purchasing.

Jimma (commodity/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 rather inconsistent—most maps show "Jimma," but coffee burlap bags are printed with "Djimmah." This is Ethiopia's largest producing region, accounting for one-third of exports.

The Kaffa forest is known for its primitive wild varieties, and Jimma is the collection and distribution center for Kaffa in this area. Farmers habitually transport coffee picked from forest areas to Jimma, then blend hundreds of varieties together to sell as commercial beans, causing the aromas of many delicious varieties to be masked.

Although washed specialty Jimma lacks the citrus and floral notes of Yirgacheffe, its flavor profile is quite clean and transparent, similar to Central American specialty coffees. Commercial-grade specialty Jimma is very common in Taiwan; with luck, you can find good-quality Jimma at a reasonable price, with a refreshing lemon peel aroma that rivals Sidamo. Overall, Jimma has better flavor than Brazil's mass-market commercial Santos and is a good mid-to-low-priced blend bean.

Illubabor (commodity/commercial bean region): Elevation 1,350–1,850m | Forest/semi-forest coffee system |

Located in western Ethiopia, bordering Sudan, it is the westernmost producing region. Coffee genetic diversity is second only to the Kaffa forest. Beans are noticeably larger than Yirgacheffe and Sidamo, with lower fruit acidity, good body, and balanced flavor. Coffee from here is mostly transported to Jimma for blending and rarely sold independently.

Gimbi, Lekempti (commodity/commercial bean region): Elevation 1,500–1,800m | Forest/semi-forest coffee system |

This region has both natural and washed beans. Bean appearance is close to Harrar's long beans, and a small amount of specialty grade is quite popular in Europe and America. Most is called "the poor man's Harrar," with fruit acidity and fruit flavors superior to Illubabor and a bright flavor profile.

Teppi, Bebeka (commodity/commercial bean region): Elevation 500–1,900m | Garden/forest/semi-forest coffee system |

The two producing regions are located close together, with Teppi north of Bebeka, and feature enterprise-managed coffee plantations. In recent years, the garden system has been promoted to increase farmer income, with annual production of about 3,000 tons. Both areas have wild coffee, with low yields and flavors completely different from Harrar and Yirgacheffe—low fruit acidity is the biggest characteristic, suitable for blend beans. Both natural and washed are available.

Lake Tana area (alternative region): Elevation 1,840m | Forest system |

Monastery coffee. The surrounding forest coffee has an extremely low annual production of less than 10 tons, so strictly speaking it cannot be called a producing region. The Orthodox monasteries, churches, religious murals, and mythology scattered around the lake area have created the world's most "divine" coffee. European monastery monks established 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.

Flavor Description

Citrus and black tea on the palate, transitioning with temperature to reveal cream, caramel, and almond in the finish. Pronounced sweet aftertaste with a clean, sweet mouthfeel.

[Burundi]

The Republic of Burundi is located in east-central Africa, south of the equator, bordered by Rwanda to the north, Tanzania to the east and south, the Democratic Republic of Congo to the west, and Lake Tanganyika to the southwest. The country is mostly highlands and mountains, largely consisting of the highlands on the eastern side of the East African Rift Valley, with a national average elevation of 1,600 meters—hence the name "Land of Mountains." Burundi's mountainous terrain, suitable elevation, and climate are very well suited to coffee cultivation. Front Street Coffee noticed through maps that the title "Heart of Africa" is truly well-deserved—its national shape resembles a heart.

Burundi coffee beans are mainly produced by numerous smallholder farmers, mostly concentrated around washing stations within the country. Washing stations in different producing regions form their own management integration units (SOGESTAL for short), i.e., washing station management associations. The association's main function is to provide better hardware and equipment for the area, and it has contributed greatly to the improvement of Burundi coffee quality in recent years. Burundi's best coffee is washed and mostly Bourbon variety.

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

Burundi coffee bears a striking resemblance to neighboring Rwanda, and the coffees from the two countries are often confused. Burundi's coffee cultivation is dominated by Bourbon, with traditional washed processing of coffee cherries. The main characteristics of its specialty coffee are elegant sweetness and bright citrus aromatics.

Flavor notes: 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 finest examples carrying blackcurrant flavor and aroma. Auctions are held every Tuesday during harvest season in Nairobi, with the best lots triggering bidding wars. In recent years, Kenyan green coffee prices have been high and prone to disappointment. Front Street's roasters and baristas frequently work overtime roasting and cupping newly arrived Front Street Kenyan coffees, striving to present a cup of Kenyan coffee that is both clean and beautifully acidic.

[Kenya's 6 Major Producing Regions]

Nyeri and Murang'a

The bright acidity and full body that most people love can be found here. Being not far from Nairobi, many foreign buyers visit during the harvest season.

Nyeri

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

Kirinyaga

Flavor is likewise bright fruit acidity with medium oily body and delicate sweetness.

Embu

The acidity here is not as powerful as Nyeri's; the flavor is balanced and clear, with mostly good finishes.

Machakos

This region is on the rise, known for clean fruit acidity, delicate flavors, medium body, and a refined, fresh finish, attracting many buyers in recent years.

Western Producing Regions

Flavors are quite different from the central producing regions, attracting buyers with medium-full sweetness and milder flavors. Some washing stations in this area carry hazelnut and mild fruit flavors, 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 pronounced 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 continue to develop 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 sensory experience. It rarely reaches the Western Hemisphere, so if you see it, seize the opportunity to taste it. You'll find a softer, more floral East African style—sweet, delicate, and bright.

[Rwanda: Land of a Thousand Hills]

The Republic of Rwanda is a landlocked country in east-central Africa, located south of the equator, bordered by Tanzania to the east, Burundi to the south, the Democratic Republic of 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–May is the long rainy season, and October–December is the short rainy season, with average annual precipitation of 1,000–1,400mm.

Rwandan Coffee and Geography

The country is mostly mountainous highlands, with over 1,800 hills of various sizes—hence the name "Land of a Thousand Hills." The east is mostly hills, marshes, and lakes with a dense water network and vast natural pastures; the central area is lowland along the lake; the northwest is a mountain range composed of volcanoes. Rwanda is closest to the equator, but at elevations above 1,500 meters, the average annual temperature is 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 also very popular in international markets. In its unique growing environment, Rwanda's high-quality coffee possesses a distinctive taste and aroma. It is precisely these distinctive flavors that prompted Front Street to bring in a bean from Rwanda, hoping to share its uniqueness with everyone.

According to Karuritsuva, marketing and promotion officer of the Rwanda Coffee Association, 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 depicted on the Rwandan coffee trademark, a coffee-colored dove flies up from a coffee cup, accompanied by the words "Cup of Hope."

Rwanda coffee's flavor is described as "grassy aroma" with tropical climate characteristics. Through cupping, Front Street found that Rwandan coffee, besides fruit sweetness, offers a refreshing, bright, and fresh sensation. The Bourbon coffee grown in Rwanda is remarkable for its fruit sweetness, with a rich, full aroma and absolutely no astringency, with a long finish. This coffee has a pleasant citrus sweetness, deep chocolate color, and high-quality sweetness and balance reminiscent of red apple, cherry, cinnamon, and honey, with a finish of cinnamon, almond, and chocolate flavors.

[Tanzania]

Tanzania is one of humanity's places of origin, with trade links to Arabia, Persia, and India dating back to before the Common Era. The United Republic of Tanzania is located in East Africa, south of the equator, and is a member of the Commonwealth of Nations. It borders Kenya and Uganda to the north, Zambia, Malawi, and Mozambique to the south, Rwanda, Burundi, and the Democratic Republic of Congo to the west, and the Indian Ocean to the east. Front Street 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 over 20 small islands. The mainland borders the Indian Ocean to the east, Zambia, Malawi, and Mozambique to the south, Rwanda, Burundi, and the DRC 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; the East African Rift Valley runs north-south through the country, splitting into eastern and western branches from Lake Malawi. Mount Kilimanjaro's Kibo Peak in the northeast, at 5,895 meters, is Africa's highest peak.

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

| Cultivated Varieties

Front Street has learned that the most commonly cultivated coffee varieties in Tanzania are Bourbon, Typica, and Kent.

Bourbon

What is usually called Bourbon mostly refers to Red Bourbon. After Red Bourbon flowers and fruits, the coffee cherry color changes as follows: green → slightly yellow → slightly orange → ripe red → darker red—hence some call it "Red Bourbon." Bourbon grown at high elevations typically has better aroma and bright acidity, with a flavor even reminiscent of red wine.

Typica

Excellent flavor expression and recognized as a specialty coffee variety, but extremely low yield and susceptible 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 direct 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 the Mysore region of India, developed by crossing S288 with Typica, featuring high yield and rust resistance. Its coffee aroma is fuller than Bourbon, and it was later introduced to Kenya, Indonesia, and other New World producing countries, making outstanding contributions.

| Processing Methods

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

| Grading

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

AA Plus (AA+): AA grade with exceptionally outstanding cup quality (flavor, mouthfeel); AA screen size 17–18

AB screen size 15–16, accounting for the majority of production

C screen size smaller than AB

TT lighter beans blown out from AA and AB grade beans using an airflow separator

T lighter beans blown out from C grade beans using an airflow separator

E Elephant Bean: Large mutant bean formed by two beans fused together, also called elephant ear bean

UG Does not meet the above standards

PB Peaberry, classified by appearance, unrelated to flavor or weight

Flavor grades in order:

TOP, PLUS, FAQ

FAQ (Fair to Average Quality) may contain some slightly defective beans, but Front Street believes this does not affect the flavor.

Coffee Taste:

Tanzania is a typical East African country, bordered by 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 neighboring Kenya. Compared to Kenya's finest beans, Tanzanian coffee has slightly less bright acidity, appearing softer and gentler, with more sweet aroma—a strong vinous character is also a hallmark of Tanzania.

In northeastern Tanzania stands Mount Kilimanjaro, Africa's highest peak. After World War I it was designated a mandate territory and was under British colonial rule, gaining independence in 1964. Bourbon variety coffee was first introduced for cultivation in 1893, with green bean processing primarily washed. High-quality, high-elevation Tanzanian coffee, like Kenya's, exhibits vibrant, bright acidity.

Tanzania's northern coffee-producing regions include Moshi and Mbeya around the Kilimanjaro foothills highlands, while to the south the Songea-Ruvuma region along the Ruvuma River dominates. Due to different growing elevations, styles vary slightly. Coffee from the southwestern Ruvuma region has vinous and fruit aromas, distinct from coffee from the northern Kilimanjaro area.

The Kilimanjaro volcanic area in northeastern Tanzania is also the country's largest coffee-producing region, accounting for 75%. Generally speaking, Tanzanian coffee beans have exceptional quality. Important producing regions are in the northern mountains near Kenya, with smallholder farmers accounting for 85% of cultivation, at elevations between 1,300–2,000 meters. Its coffee flavor differs from neighboring Ethiopia and Kenya, combining characteristics of both—good body with fruit and floral aromas—well worth trying. Coffee is a dicotyledonous plant; generally, a single coffee cherry normally contains a pair (two halves) of coffee seeds—what we call coffee beans.

Compared to flat beans, peaberries—also called caracol or caracolillo, Spanish for "little snail"—are round beans. Botanically, peaberries are said to result from 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 from uneven nutrition during growth (usually more likely at the end of branches), where nutrients are absorbed by only one cotyledon, and only the nourished cotyledon develops 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%, relatively rare in yield. Because their shape and size differ from normal flat beans, peaberries are often graded and sold separately through screen sizing.

Northern coffee is full of aroma, with bright acidity and full body, benefiting from fertile volcanic soil and carrying a mineral water-like sweetness.

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

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 notes. This coffee tastes excellent whether served hot or as iced coffee. Paired with orange or berries, its bright flavors are even more pronounced. This is exactly the case with a coffee bean from Kilimanjaro, Tanzania that Front Street has brought in.
