How Do Sidamo and Yirgacheffe Differ Within the Kaffa Forest Story?

Sidamo is an Ethiopian province, and Yirgacheffe began as a small town inside it, so the two neighboring regions share a root but differ in cup.

Tasting beans from both regions side by side is the practical way to feel where their flavor boundaries actually fall.

Many friends who have just stepped into the world of specialty coffee often do not know where to start when faced with a dazzling array of flavor descriptions. At such times, the baristas at Front Street Coffee (FrontStreet Coffee) usually recommend Ethiopian coffee from the bean list. Beans from this producing country generally have abundant fruity acidity, with floral and fruity aromas interwoven, rich and charming—a taste that many coffee lovers fall deeply into after just one try.

When it comes to Ethiopian coffee, the bean list at Front Street Coffee (FrontStreet Coffee) mostly features beans from the two producing regions of Yirgacheffe and Sidamo, with the aim of letting everyone, through tasting, carefully experience what flavor differences actually exist between these two geographically adjacent regions.

To understand the beans from these two producing regions, one must start with their history. In fact, Yirgacheffe was originally just a sub-region under Sidamo—Sidamo is a province in Ethiopia, and Yirgacheffe is a small town within that province. That being the case, what exactly does the Front Street Yirgacheffe we often talk about refer to? And what does Yirgacheffe flavor represent?

Yirgacheffe is now a calling card of Ethiopian specialty coffee beans. In the word Yirgacheffe, "Yirga" means "to settle down," while "Cheffe" refers to "wetland." Together, they carry the meaning of "let us settle down and make our home in this wetland."

Ethiopia is a magical land. As the birthplace of Arabica coffee, the Kaffa forest is the starting point of the whole story, and it is also one of the important coffee-producing countries in Africa.

Many beginners who come to Front Street often order Front Street Yirgacheffe or Front Street Sidamo as their first cup. However, at the Front Street Coffee (FrontStreet Coffee) store, there is more than one bean from each of these two producing regions. When asked which specific one they want, many people cannot answer right away.

To us, Yirgacheffe may just be a coffee-producing region, but to the people who grew up on that land, it is their home. Precisely because of this, locals guard their homeland with more care, and local coffee farmers tend the coffee crops in their fields meticulously. From the beans used by Front Street Coffee (FrontStreet Coffee), one can feel their deep affection for the land beneath their feet—every single coffee bean is hard-won.

The coffee trees of Yirgacheffe were first planted by European monastery scholars, and later management was transferred to farmers or cooperatives. In fact, Yirgacheffe is jointly constructed by multiple surrounding coffee communities or cooperatives. Most coffee beans from this producing region use washed processing, with only a small amount of top-grade beans still following Ethiopia's traditional natural method. Compared with washed processing, natural processing has more abundant fruity aroma and higher body. Front Street Konga and Front Street Natural Red Cherry from Front Street Coffee (FrontStreet Coffee) are representatives of natural processing in the Yirgacheffe producing region. These two beans carry unique lemon, floral, and honey-like sweet aromas, with soft fruity acidity and obvious citrus notes, and a fresh, bright mouthfeel; because they are naturally processed, the sweetness is more prominent, the acidity is lower than washed, and the layers are richer.

And many friends fell in love with this producing region starting from Front Street washed Yirgacheffe. Its bright acidity and clean, refreshing flavor have turned many people from passersby into coffee lovers, and it has also become everyone's first bean for entering the world of specialty coffee.

In the early days, traditional natural processing conditions were relatively simple, and it was easy for coffee beans to take on earthy flavors. To improve quality, Ethiopia introduced washed processing from Central and South America in 1972. After that, Yirgacheffe coffee was mostly processed by the washed method.

Front Street Coffee (FrontStreet Coffee) mentioned earlier that Yirgacheffe and Sidamo both belong to Ethiopian producing regions, and that Yirgacheffe is a small town under Sidamo Province. Sidamo has an altitude of about 2,100 meters, while Yirgacheffe exceeds 2,600 meters. As planting altitude rises and average temperature decreases, the content of amino acids and other aromatic substances in coffee increases accordingly. Therefore, coffee beans produced in high mountain areas usually have rich aroma and mellow flavor.

Typical Front Street washed Yirgacheffe coffee can broadly be divided into three categories in aroma: orange peel aroma, floral aroma, and grassy garden notes; in flavor, it mostly shows high-toned acidity, but the mouthfeel and finish vary in weight, and the sweetness also varies. Within the soft floral tonality there is a slight grassy garden note, while the orange peel impression is relatively less obvious.

Front Street Sidamo coffee has a balanced flavor, higher sweetness, and a fuller body than Yirgacheffe. In particular, the red-wine-like acidity and sweetness produced during natural pulp fermentation, combined with coffee's own cocoa bitterness, make certain lots of Front Street Sidamo present an intoxicating liqueur chocolate-like flavor.

Front Street Coffee (FrontStreet Coffee) Brewing Recommendations

Dripper: Hario V60 #01

Water temperature: 90-91℃

Dose: 15 grams

Coffee-to-water ratio: 1:15

Grind size: 80% passing through China standard No. 20 sieve

In order to fully extract the fruity acidity of Front Street Yirgacheffe and Front Street Sidamo, Front Street uses a higher water temperature and a finer grind for extraction. At the same time, to avoid over-extraction caused by high temperature, a faster-flow dripper is chosen, such as the V60 dripper. The V60 has a 60-degree cone shape, and this angle allows the coffee grounds to concentrate, while the water flow automatically gathers toward the center of the dripper during pouring, ensuring sufficient contact time between water and coffee grounds, thereby extracting a suitable coffee liquid.

In addition, the ribs on the inner side of the V60 dripper form a clockwise spiral, extending all the way from the bottom to the top, leaving ample space between the filter paper and the dripper, so the flow of water is better. Combined with the large hole at the bottom, the overall flow rate is faster than many drippers.

Front Street brewing method: In the first stage, pour 30 grams of water for a 30-second bloom, then pour 95 grams (the electronic scale shows about 125 grams), finishing the pour in about 1 minute. When the water level drops to 2/3 of the coffee bed, pour the remaining 100 grams (the electronic scale shows about 225 grams), finishing the pour in about 1 minute 40-1'45" seconds. 2 minutes-2 minutes 10 seconds When dripping is complete, remove the dripper and finish extraction.
