The Story of Rwandan Coffee

Rwandan coffee is the most popular African coffee after Kenya and Ethiopia. However, unlike these two famous producing countries, it doesn't have a long history of cultivation, nor does it have native varieties growing wild everywhere. This small African nation is a phoenix reborn from ashes.

Rwanda is one of Africa's smallest and most densely populated countries, with an area comparable to Maryland. In this country, the average family farm is less than one hectare. Rwanda's coffee production is essentially a smallholder economy, with approximately 430,000 families now producing coffee in Rwanda, and most farms have fewer than 200 coffee trees.

Rwanda possesses ideal growing conditions for Arabica coffee, with coffee cultivated at altitudes between 1350m and 1850m. Rwanda's fertile volcanic soil, abundant rainfall, and mild year-round climate all promote the maturation of coffee beans, and this special growing environment imparts unique flavors to the coffee. Rwandan coffee rarely uses chemical fertilizers or pesticides. Soil nutrients come from natural ground cover and traditional fertilization methods.

Rwanda, known as the "Land of a Thousand Hills," sits on the equator and is surrounded by East African countries including Congo, Uganda, Tanzania, and Burundi. Geographically, it has suitable conditions for coffee cultivation, but since its introduction by German missionaries in 1904, Rwandan coffee was poorly processed commercial grade, with most exported to the colonial power Belgium. The push for specialty coffee production only began after experiencing the devastation of war and getting the economy back on track.

The genocide of 1994 claimed over one million lives, mostly from the Tutsi ethnic group. Today, Rwandan streets still bear witness to orphaned survivors from that time, memorials are visible everywhere, and war criminals constitute 90% of the total prison population! Since 2001, the Rwandan government established the NAEB (National Agriculture Export Development Board) to focus on improving coffee exports and earning foreign exchange.

With government support, farmers shifted from rough home processing to transporting fresh harvested fruits to nearby coffee washing stations for full washed processing. In just 12 years, the number of washing stations nationwide increased from two to 220. They are now all privately owned, either by exporters or farmer cooperatives. Due to the small average farm size (each farm has fewer than 200 coffee trees on average), each station serves about 50 to 100 farms. The NAEB employs 200 botanists and cuppers who regularly visit washing stations to inspect quality and educate farmers on soil management, organic farming, pruning, pest control, and harvesting techniques.

Rwanda Coffee Processing Methods

In 2000, Rwanda, having just experienced internal turmoil, sought to upgrade its coffee industry. Michigan State University led a coalition including Texas A&M University and the National University of Rwanda, with several researchers working together to help Rwanda upgrade its coffee industry. The project was abbreviated as PEARL (Partnership for Enhancing Agriculture in Rwanda through Linkages project).

The PEARL project aimed to improve both the quality and quantity of Rwandan coffee and help farmers achieve better incomes, creating a virtuous cycle. After the implementation of the PEARL project, Rwanda successively built 46 coffee washing plants, leading to significant growth in Rwanda's economy through strong coffee bean exports. The PEARL project was also the largest and most comprehensive development plan implemented in Rwanda since independence.

Therefore, Rwandan coffee beans now mainly use the washed processing method. During each harvest season, farmers harvest ripe coffee cherries and concentrate them at washing plants for processing. First, manual selection ensures no unripe or damaged fruits are mixed in. Next, the fruit skin is removed, followed by a 12-18 hour washed fermentation process in a cool, low-temperature environment, cleaning away the attached mucilage in channels. During the rack drying process, washing plant members manually turn and carefully tend to the beans, ensuring that under adequate sunlight, the parchment beans don't lose moisture or experience uneven drying until the bean's moisture content stabilizes below 14%.

Strict Control of Drying Speed

The Bourbon variety accounts for over 90% of Rwanda's production. A small portion of farmers grow Bourbon varieties BM-139 and Jackson. The southern and western mountainous regions have more cultivation and more famous washing stations, such as Gitesi, Huye Mountain, and Mibirizi. Compared to the common practice in Central America of drying on concrete patios, Rwanda dries parchment coffee on African beds covered with canvas, controlling drying speed and gradually reducing the bean's moisture content to the target 11% over 10 to 15 days. Compared to sun-drying, this method helps preserve organic compounds. Rwanda was the first African country to host a Cup of Excellence competition. This year marks the 5th edition. In terms of flavor, Rwandan coffee has distinct floral and fruity aromas, with a tea-like smooth mouthfeel. It has the highest balance among African countries.

Rwanda is a small landlocked country in East Africa with hilly terrain, fertile soil, and ancient Bourbon varieties, with high-quality coffee beans cultivated throughout the country. Coffee was reportedly introduced to Rwanda by German missionaries in 1904. Coffee was the only crop that rural farmers could earn income from, and while coffee flourished, unlike neighboring countries, there was no centralized auction system, allowing farmer cooperatives to trade directly with buyers. Traditionally, Rwandan coffee was exported to Europe via Uganda through Kenya's Mombasa port.

In the past decade, due to civil war and genocide, Rwanda's premium coffee could not be exported, leading to a sharp decline in coffee cultivation. The 1994 genocide claimed nearly 500,000 lives and nearly wiped out coffee cultivation knowledge and techniques. After the war, with U.S. aid and assistance from some international organizations, it gradually recovered and began cultivation again. Due to war and genocide, among the surviving small coffee farmers, a high proportion are women and even widows. When we can obtain Grade A Rwandan coffee from these small farmers or estate cooperatives, the emotional impact is truly hard to describe, especially since its flavor is not inferior to Kenya's auction bidding beans or Yirgacheffe, and even has unique charming qualities worth savoring slowly...

Rwandan Coffee and Starbucks

In the early stages of the SPREAD program, in 2006, Starbucks began selling Rwandan coffee beans, including them in Starbucks' premium product line "Black Apron" (the internal certification program for "Coffee Masters," where regular Starbucks employees wear green aprons, and only through rigorous examinations and competitions can they earn the symbolic black apron). Starbucks selected Bourbon variety coffee beans from two Rwandan washing stations (Sholi Cooperative Washing Station and Musha Cooperative Washing Station), naming it "Blue Bourbon" and selling it for $24 per pound.

FrontStreet Coffee's Roasting Recommendations

Due to the high altitude of Rwandan coffee, its density is high. For such hard beans, higher bean drop temperatures and larger heating rate ramp conditions will present better flavors. FrontStreet Coffee recommends dark roasting.

Region: Rutsiro Province, Western Province, Rwanda
Altitude: 1500-1800 meters
Variety: Bourbon
Processing Method: Washed Processing

Machine: Yangjia 800N, 550g green beans input

FrontStreet Coffee's Brewing Recommendations

*Reason for choosing Kono dripper: The Kono dripper has few ribs located at the bottom, and the filter paper fits tightly against the dripper, which can restrict airflow and increase the contact time between water and coffee powder, allowing the coffee grounds to be fully extracted and enhancing the rich mouthfeel.

FrontStreet Coffee's Brewing Technique

Segmented Extraction

Use 30g of water for a 30-second bloom. When injecting water in a small circular motion to 125g, perform segmentation. When the water level drops and is about to expose the coffee bed, continue injecting water to 225g and stop. Wait for the water level to drop and when it's about to expose the coffee bed, remove the dripper. (Timing starts from the bloom) Extraction time is 2'00".
