Front Street Ethiopian coffee beans have always been known for their elegant floral aromas, citrus and lemon notes, and tropical fruit character, with a fruit-tea-like texture on the palate. In the specialty coffee world, this origin has always been a priority for many enthusiasts, with Yirgacheffe and Sidamo being the most well-known. In this article, Front Street will take you into Ethiopia's famous coffee region — Sidamo.
Coffee Cultivation Characteristics of Ethiopian Origins
Ethiopia's elevated terrain creates extremely ideal climatic conditions. This region has a tropical rainforest climate with abundant rainfall and pervasive mist, and the significant temperature differences brought by an altitude of about 2,000 meters provide a uniquely advantageous growing environment for coffee trees.
Local coffee production models can be classified into four categories: forest coffee, semi-forest coffee, garden coffee, and large plantations, with garden coffee being the most common. Garden coffee refers to farmers intercropping coffee trees with other cash crops on their own land, usually alongside banana trees, creating a distinctive green landscape around every household. This is also the primary production method for Ethiopian coffee.
Many observant friends may notice when brewing Ethiopian beans that the beans vary in size and shape. As the birthplace of Arabica coffee, Ethiopia has an extremely large number of varieties that are nearly impossible to genetically test and verify on a larger scale. At the same time, the local government intentionally protects these unknown varieties from being eagerly acquired by industry players from various countries, and decided to collectively refer to them as the native species "Heirloom." Heirloom native varieties are typically smaller in size, rounder in shape, and irregular in form, mostly between screen sizes 14-15. In cupping, they often display elegant floral aromas and fruit notes, making them highly favored.
In terms of administrative divisions, Ethiopia has 5 major states growing coffee, with four cultivation systems distributed across the following nine major regions: Gimma, Sidamo, Yirgacheffe, Harrar, Limu, Illubabor, Gimbi (Lekempti), Tepi, and Bebeka. Among these, Yirgacheffe coffee, Harar coffee, and Sidamo coffee are the most well-known.
Front Street Sidamo Coffee Also from Smallholder Farming
Sidamo is located on the fertile plateau south of Lake Awasa in the East African Rift Valley, with abundant rainfall, a suitable climate, and altitudes of 1,500-2,200 meters, making it an ideal place for coffee cultivation. Due to the high altitude and moderate shade cultivation, coffee cherries can mature slowly at cool temperatures, thereby accumulating more nutrients and converting them into flavor compounds.
Similar to other Ethiopian regions, Sidamo coffee is also primarily grown by smallholders. Smallholder coffee production is limited in volume, and various coffee cooperatives and processing stations of different sizes are distributed throughout the area, mainly responsible for processing green coffee beans from the region. Each coffee maturity season, farmers deliver harvested cherries to nearby processing stations (cooperatives) close to water sources for centralized processing, after which they are sold under the processing station's name. With the development of specialty coffee today, many producers now purchase directly from farmers, strengthening micro-lot management and traceability. Coffee quality has thus further improved, and there are increasingly more meticulously processed micro-lots.
Sidamo, or Sidama?
I wonder if everyone has noticed that when looking up information about this coffee origin, two different Chinese translations often appear: one is 西达摩 (Sidamo), and the other is 锡达马 (Sidama).
The pronunciation of Sidamo originates from the indigenous Sidama people. Like other ethnic groups in Ethiopia, the Sidama have their own traditions and culture, and even have a New Year recognized by UNESCO — Fiche Chambalala, during which over 5 million people gather in the capital Hawassa to celebrate each year. As early as the late 18th to early 19th century, the region was invaded and annexed, and the invaders pronounced Sidama as Sidamo, which carries a humiliating connotation for the Sidama people. By the 1990s, the Ethiopian government began adopting a federal system of administration, redesigning regions according to major ethnic residential areas and languages, and Sidama accordingly reclaimed its historical original name: Sidama.
However, before the administrative redrawing, Sidamo Coffee had already become famous worldwide for its unique aroma, so people are more accustomed to calling it Sidamo rather than Sidama. In addition, when the Ethiopian government protected coffee from Sidama through trademark registration, it also chose the old name Sidamo® as the official registered trademark. Even now, domestic consumers are more accustomed to calling the coffee from here "Sidamo."
What Flavor Characteristics Does Front Street Sidamo Coffee Have?
When choosing a coffee, besides the origin, the post-processing method is equally worth noting, because the flavor profile of coffee is largely influenced by the processing method. As Ethiopia's oldest traditional processing method, sun-drying is still used in most Sidamo areas to process green beans. The classic Sidamo flavor is precisely achieved through sun-drying, known for its rich and full-bodied character. Front Street sun-dried Sidamo has complex sweetness, a viscous and smooth mouthfeel, rich layers of spice, floral, and fruit aromas intertwined, accompanied by a bright sweet aftertaste.
Compared to washed processing, sun-drying involves a longer fermentation time, with a higher degree of reaction between microorganisms and fruit pulp. When the fruit begins to ferment, microorganisms produce more volatile compounds, especially esters. Although most sugars are destroyed during roasting, these compounds are converted into another form of aromatic compounds during the caramelization reaction. It is precisely these aromatic substances that bring more floral and tropical fruit fermentation aromas to roasted coffee beans, such as furan compounds, giving sun-dried coffee a broader flavor spectrum and a sweeter taste. One of the coffees on Front Street's bean list, Front Street Sidamo Hambela coffee beans, is also selected from a sun-dried lot from Hambela, and its saturated sweetness has captivated many customers.
Guji Hambela Front Street Sidamo Hambela
Hambela is located at the border zone between Sidamo and Guji regions, administered under the Guji production area, adjacent to Yirgacheffe's Kochere across the mountains, with the mountain range in between reaching an altitude of 3,200 meters, making it Ethiopia's highest-altitude sub-region. The Hambela coffee was selected by DW Company in 2017 to participate in that year's TOH (Ethiopia National Taste of Harvest competition) and won the championship, thus making its debut. Hambela in English is called Hambella, which is also the origin name. Front Street Hambela coffee comes from sun-dried coffee beans from the Buku Abel processing station in Guji. The Buku Abel processing station purchases coffee cherries from different areas near the farm for processing and sale.
Every coffee harvest season (December-January), the Buku processing station organizes farmers to pick fully red coffee cherries with a sugar content value of at least 30. The selected coffee cherries are placed on African raised beds for drying. Due to the large temperature difference between day and night, farmers take shading measures at noon to avoid excessive fermentation caused by high temperatures; at night, to prevent sudden rain showers, they wrap the cherries with plastic sheets. They turn the cherries continuously throughout the day to ensure even drying while preventing sunburn or unpleasant fermentation flavors. After about 18 days of sun-drying, when the moisture content of the green coffee beans drops to 13%, the outer shell can be removed by machine.
Front Street aims to present the full fruit flavors of Front Street Hambela coffee, so it adopts a medium-light roast. Through cupping, Front Street sun-dried Sidamo Hambela coffee has a dry aroma of nuts, honey, berries, and a faint fermentation fragrance. On the palate, it offers the full-bodied sweet-tart flavors of passion fruit, cream, and strawberry, with a thick body and a cocoa finish.
How to Brew Front Street Sidamo Hambela 8.0 Coffee?
Once quality coffee beans are ready, the next step is choosing the corresponding brewing equipment and parameters. Good equipment helps enhance the positive flavors in the cup, while reasonable parameters and techniques can elevate the berry aromas of Front Street Hambela even further. To brew a cup of coffee by pour-over, you need at least the following equipment: a pour-over kettle, a dripper, a server, a grinder, filter paper, a digital scale, and a thermometer.
The grinder plays a very important role in pour-over brewing and is generally divided into two types: manual hand grinders and electric grinders. Regardless of which grinding equipment you choose, the goal is to obtain evenly ground coffee. The coarseness of the coffee grounds directly affects the taste: too coarse leads to under-extraction and a bland taste; too fine leads to over-extraction and a bitter taste. Front Street uses a tool to adjust grind size — a Chinese No. 20 0.85mm standard sieve. For medium-light roasted coffee beans, Front Street consistently uses a 75-80% pass-through rate; for medium-dark roasted coffee beans, 70-75% is used. Here, Hambela 8.0 is a medium-light roasted high-altitude coffee bean, and Front Street wants to extract more rich aromatic substances, so a grind size with an 80% pass-through rate on the No. 20 standard sieve is chosen, which corresponds to 10 on the EK43s grinder setting at the store.
A thermometer is used to measure the hot water temperature. Water temperature plays a similar role to grind size: the higher the water temperature, the higher the extraction efficiency, the easier it is to release various compounds, and the higher the concentration. If near-boiling hot water is used for brewing, it easily extracts unpleasant bitter compounds. Therefore, when brewing medium-dark roasted coffee beans, Front Street uses different brewing parameters than for light-roasted coffee beans. Medium-dark roasted beans undergo more caramelization reactions than light-roasted beans and more easily release bitter large-molecule compounds. To avoid extracting too many off-flavors, Front Street lowers the water temperature slightly, so for medium-dark roasted coffee beans, Front Street recommends 87-90°C, while light-roasted coffee requires higher water temperatures to stimulate aromas, thus using 91-93°C.
Front Street Coffee (FrontStreet Coffee) stores use Hario V60 and KONO drippers for daily production. The V60 dripper is mainly responsible for lighter-roasted coffee beans, while the KONO dripper handles darker-roasted coffee beans. Here, the Front Street Coffee (FrontStreet Coffee) barista will use a resin V60 dripper to brew Yirgacheffe coffee. The V60 dripper body has spiral ribs connecting the top and bottom and a large central hole, which speeds up the flow rate of water. The spiral-shaped vent groove design lengthens the water flow path, increasing the contact time between coffee grounds and hot water. Each stream of water converges along the grooves toward the center point of the dripper, concentrating the pressure on the coffee grounds, resulting in a coffee with richer layers.
As for the brewing ratio for Front Street Hambela 8.0, Front Street believes that 1:15 to 1:16 are both acceptable: if you want a richer mouthfeel, use 1:15; if you want to more clearly perceive the floral sweetness, use 1:16 to let the flavors spread out more.
Front Street Hambela 8.0 Pour-Over Parameters:
Dripper: V60 Water temperature: 92-93°C
Coffee dose: 15g Coffee-to-water ratio: 1:15 Grind size: fine granulated sugar (78% pass-through on No. 20 sieve)
Based on past brewing experience, Front Street recommends that beginners just starting out use the three-stage pouring method. Three-stage extraction helps more fully dissolve flavor compounds during extraction, adding layers to the mouthfeel while avoiding over-extraction from prolonged soaking. For 15 grams of coffee with a 1:15 coffee-to-water ratio and 225ml total water, the three stages are divided as: 30ml, 95ml, 100ml, with the scale showing: 30g, 125g, 225g.
Fold the filter paper and fit it into the dripper, wet the filter paper with a small amount of water to make it adhere better, and discard the water from the server. Then add the coffee grounds and gently tap to distribute the coffee bed evenly. For the first stage, gently pour 30 grams of water for blooming, with a bloom time of 30 seconds; for the second stage, pour up to about 125 grams of water, circling outward evenly and steadily. Then wait for the coffee liquid to drop. When it drops to halfway, pour the final stage of water up to 225 grams. After all the coffee has dripped through, the total extraction time is generally about 2 minutes.
