What defines Kilimanjaro coffee from Tanzania?

Tanzania's Kilimanjaro region is the country's most representative coffee area, and this guide follows a washed AA lot from variety origin through processing, bean shape, cupping, and brewing. It records the medium-light roast profile, the cup scores, and the parameters used, then compares the result with washed Bourbon from southern Tanzania.

Tanzanian coffee was introduced by missionaries and the original variety was Bourbon, while Typica bean shape characteristics also appear in the region's lots. Mount Kilimanjaro sits in northeastern Tanzania, and coffee grows on its volcanic slopes where fertile, slightly acidic soil and cool, rainy mountain conditions support compound accumulation in the cherry.

Tanzania is an important coffee-producing country in East Africa, with the Kilimanjaro region being its most representative area. This article starts with the Tanzanian Kilimanjaro coffee on Front Street Coffee's bean list, examining its variety origins, washed processing flow, Typica bean shape characteristics, and AA grading standards, and records the cupping performance and brewing parameters after a medium-light roast. The article also compares the cupping differences with washed Bourbon from southern Tanzania, presenting the different directions of coffee from the two regions in terms of acidity, sweetness, and aroma, helping coffee enthusiasts understand the full flavor profile and selection direction of Tanzanian coffee.

Tanzania is a typical East African country. When talking about Tanzanian coffee, one cannot fail to mention the coffee produced in the Kilimanjaro region. Tanzanian coffee was introduced by missionaries, and the variety was Bourbon. Mount Kilimanjaro is located in northeastern Tanzania and is the highest mountain range in Africa. Coffee produced in the Kilimanjaro region is absolutely the best representative of Tanzania. Front Street Coffee's bean list includes coffee beans from Mount Kilimanjaro in Tanzania.

When Front Street Coffee mentions African countries, many people may have the impression that Tanzania and other African countries have hot, arid climates. The Kilimanjaro region of Tanzania is an exception. Why does Front Street Coffee say this? Because although the mountain temperatures of Kilimanjaro can reach as high as 59 degrees Celsius, the summit can have year-round snow, reaching as low as minus 34 degrees Celsius. Thus Kilimanjaro is also known as the "Snow Peak on the Equator." In terms of rainfall, the river valley can receive 800 to 900 mm of annual precipitation; the mountain area is cool and rainy, with annual precipitation on the windward slope reaching 1,600 to 1,800 mm. Coffee grows in the climate and geographical environment provided by this "Snow Peak on the Equator," which is very conducive to the accumulation of coffee compounds.

In Front Street Coffee's view, this unique climate condition is a treasure land for growing coffee. The volcanic soil of the high Kilimanjaro mountains is fertile, slightly acidic, and well-draining. The combination of climate and geology makes the coffee flavor richer. Therefore, this Tanzanian coffee bean launched by Front Street Coffee has a very high-quality sweet aroma and red wine character, with the typical characteristics of African Ethiopian coffee beans.

Due to Tanzania's abundant rainfall, washed processing is mostly used in Tanzania to process coffee beans. This coffee from Mount Kilimanjaro in the northern highlands of Tanzania, launched by Front Street Coffee, is washed processed. Coffee farmers send the harvested coffee cherries to the nearest processing station for processing. The general washed processing method is:

1. Screen and remove impurities mixed in the coffee cherries. 2. Remove the coffee pulp and outer skin. 3. Send to fermentation tanks to remove the pectin layer adhering to the inner skin through fermentation. 4. After washing clean, carry out drying treatment. When the moisture content of the coffee beans drops to about 11%, they can be stored in the warehouse. Because washed processing is used, the silver skin center line of this Tanzanian Kilimanjaro coffee bean from Front Street Coffee is preserved. However, too much silver skin on coffee beans is not a good thing, because after grinding the coffee beans into powder, the silver skin will also remain in the coffee grounds, affecting the extraction of coffee compounds.

The green coffee beans of Front Street Coffee's Tanzanian Kilimanjaro are uniform in size, slightly elongated in shape, and full-bodied, which is the typical Typica bean shape of Ethiopian coffee beans. The coffee varieties commonly grown in Tanzania are Bourbon, Typica, and Kent. The variety of this Tanzanian coffee from Front Street Coffee is Typica, one of the ancient varieties. Its flavor performance is excellent and it is recognized as a specialty coffee variety. Its only drawback is low yield and susceptibility to leaf rust disease.

Like neighboring Kenya, Tanzanian coffee also uses bean size as the grading standard. The highest-grade batch is AA, followed by AB. The washed Kilimanjaro coffee that Front Street Coffee has acquired this time is precisely the highest grade, AA.

The new-season Tanzanian Kilimanjaro coffee beans have a relatively high moisture content, so the dehydration time needs to be extended to allow the bean surface and bean core to be heated evenly. In addition, to highlight the sweetness, acidity, and floral-fruity aroma of this Tanzanian coffee bean, Front Street Coffee decided to use a medium-light roast, extending the caramelization reaction after first crack to make the sweetness more pronounced.

Afterward, Front Street Coffee cupped this roasted coffee bean. The dry aroma of this coffee bean from Mount Kilimanjaro in Tanzania has a slight orange freshness and a caramel sensation. The wet aroma makes this sensation even more pronounced. During Front Street Coffee's overall cupping process, when the coffee liquid was still at high temperature, the coffee flavor leaned more toward citrus, nuts, honey, and cream. After cooling, the sensation became acetic acid, cocoa, and spice similar to black pepper pungency.

Therefore, after summarizing the cupping situation of this Tanzanian coffee, Front Street Coffee found that the advantage is medium-high sweetness, similar to honey, with balance, but the disadvantage is medium-low acidity, not as pronounced as Kenyan coffee beans, and it carries a slight astringency when cooled. So the brewing plan should maximize strengths and minimize weaknesses, highlighting the advantages and reducing the appearance of disadvantages. The parameters for Front Street Coffee's brewing of this coffee are: select 15 grams of coffee beans, powder-to-water ratio of 1:15, water temperature of 90 degrees Celsius, grinding degree of BG grinder #6M, and V60 dripper.

Use Front Street Coffee's commonly used three-stage method for brewing. Use 30 grams of water for blooming for 30 seconds. Pour water in a small stream in circles until 125 grams for the first stage. When the water level drops and is about to expose the coffee bed, continue pouring water until 225 grams and stop. When the water level drops and is about to expose the coffee bed, remove the dripper. (Timing starts from the beginning of blooming.) The extraction time is 2'00". The brewed Tanzanian coffee leans more toward citrus and nuts in flavor, with a smooth mouthfeel and a black cocoa finish. When cooled, it carries honey sweetness and spiciness, with lower astringency.

This is the basic flavor of Tanzania's Kilimanjaro region, because Tanzanian coffee cultivation areas are mainly Mount Kilimanjaro and southern Tanzania. Front Street Coffee has already cupped the coffee beans from Mount Kilimanjaro. So how does the coffee flavor of southern Tanzania differ from Kilimanjaro? Front Street Coffee is very curious, and also conducted a comparison with coffee beans from southern Tanzania.

This southern region coffee bean, like the Kilimanjaro coffee bean, uses the washed method commonly used in the Yirgacheffe region of Ethiopian coffee beans, but the variety is Bourbon. Bourbon coffee also has very high sweetness and bright acidity, and its yield is even higher than Typica coffee, though it is also susceptible to leaf rust disease.

This southern Tanzania coffee bean, like the coffee bean from Mount Kilimanjaro, uses a medium-light roast to highlight the coffee flavor of the southern region. Its cupping situation is: Dry aroma: berries, fermentation Wet aroma: berries, floral Cupping: citrus, caramel, nuts, fermented aroma Flavor: Front Street Coffee used the same method to brew this southern region coffee bean. The floral aroma is also very rich, with berry and citrus acidity, and a slight nutty flavor in the aftertaste.

These two Tanzanian coffees each have their own unique flavors. Coffee beans from different altitudes also have very inconsistent flavors. Southern region coffee has rich floral aroma, wine aroma, and soft acidity; coffee from the Kilimanjaro region has bright acidity and a mellow mouthfeel, and thanks to the fertile volcanic soil, it carries a mineral water-like sweetness. It is precisely because Tanzanian coffee has a mellow texture, suitable acidity, and rich aroma that Europeans used to call Tanzanian coffee "coffee gentleman." Everyone can choose based on their own taste preferences.
