How does coffee grinding shape Sidamo floral coffee?

Sidamo is a southern Ethiopian region that became an independent administrative area in 2009, with coffee trees scattered along the East African Rift Valley and rainfall reaching up to 2000 millimeters a year. Beans here ripen slowly at altitude, building up the passion fruit and berry aromas that show clearly in a medium-light roasted natural Hambella lot.

For that style of bean, a medium-light grind and a pour-over setup work well: water around 90 to 92C, a coffee-to-water ratio near 1:15, and a dripper that keeps flow steady. Guji and West Arsi are the sub-regions most often cited for quality, and Guji was separated from Sidamo in 2010.

Although Sidamo and Yirgacheffe both belong to Ethiopia's specialty coffee regions, their flavor profiles each have their own distinctive characteristics. This article will guide you through the terroir conditions of the Sidamo region, the relationship between the Guji and Hambella producing areas, and the variety background and processing methods of the Hambella 8.0 natural coffee. At the same time, Front Street Coffee will share grinding suggestions and pour-over parameters for the medium-light roasted Hambella, including water temperature, coffee-to-water ratio, and dripper selection, to help you better unlock the passion fruit and berry aromas of this high-altitude coffee.

Those familiar with the history of the Yirgacheffe region should know that Yirgacheffe originally belonged to the Sidamo region, but was later separated and elevated to an independent region due to its clean and bright flavor profile. Because of this, although Sidamo and Yirgacheffe share the same origin, they present two entirely different floral and fruity tones. If you visit a Front Street store and say you'd like to try Ethiopian coffee beans but can't make up your mind, the baristas at FrontStreet Coffee will usually first ask: do you prefer a fresh and bright citric acidity, or a full and rich fruity sweet-and-sour sensation? This corresponds exactly to the flavor labels of Yirgacheffe and Sidamo respectively, helping customers quickly lock in their preferred direction.

Sidamo Region

Sidamo

Sidamo is located in southern Ethiopia and has been an official independent administrative region since 2009. The area has a unique ethnic traditional culture. The coffee trees here are scattered on both sides of the East African Rift Valley. The highland soil is fertile, and annual rainfall can reach up to 2000 millimeters, providing exceptionally favorable natural conditions for coffee cultivation.

In high-altitude environments, coffee cherries have a longer growth cycle and ripen later than in other Ethiopian regions, allowing Sidamo coffee cherries to accumulate richer flavor layers. The most renowned coffee-growing areas within Sidamo's jurisdiction are Guji and West Arsi.

Guji Region

The Guji region originally belonged to Sidamo. In 2010, due to its outstanding coffee quality, it was separated by the Ethiopia Commodity Exchange (ECX) to become an independent region. Guji is adjacent to Yirgacheffe, with diverse topography. The fertile black soil can reach depths of up to two meters, allowing coffee tree roots to grow deeper. The average altitude of the region exceeds 1800 meters, with significant day-night temperature differences, all of which are conducive to growing high-quality coffee. Local coffee cultivation relies almost entirely on natural nutrients—fallen leaves, dead branches, and organic matter in the soil are sufficient to nourish the coffee trees, allowing them to thrive without chemical fertilizers.

Today we still frequently see Sidamo and Guji appearing together as region names, which is related to Ethiopia's administrative division system. Local administrative units are divided into four levels, from largest to smallest: Region, Zone, woreda, kebele. Most green coffee bean naming also follows this rule. Taking Hambella as an example, it is located southeast of Yirgacheffe in the Sidamo region. Administratively, it belongs to Oromia Region → Guji Zone → Shakisso woreda → Hambella.

Hambella Hambella

Hambella is situated at the junction of the Sidamo and Guji regions, under the jurisdiction of the Guji region. It faces Kochore of Yirgacheffe across the mountains, with the mountain range in between reaching altitudes of up to 3200 meters, making it the highest-altitude sub-region in Ethiopia.

The Hambella coffee first made its appearance in 2017, when DW Company sent it to that year's TOH (Ethiopia National Taste of Harvest competition) and won first place, rising to fame ever since. The English name Hambella is taken from the Hambella place of origin. This coffee comes from a natural process lot of the Buku Abel processing station in Guji. Buku Abel processing station purchases coffee cherries from different areas around the farm for processing and sale.

Every year during the coffee harvest season (December to January), the Buku processing station organizes farmers to pick fully red cherries, requiring a sugar content value of 30 or above. The selected cherries are spread out on African raised beds for drying. Due to the extreme day-night temperature differences in the area, farmers take shade measures at noon to avoid excessive fermentation caused by high temperatures; at night, to prevent sudden rain showers, they cover the cherries with plastic sheets. The cherries are turned continuously throughout the day, while ensuring the pile thickness is not too great—this allows for even drying and prevents sun damage or unpleasant fermentation flavors. After approximately 18 days of natural processing, the green coffee beans' moisture content drops to around 13%, and the outer husk can then be removed by machine.

Local Heirloom

The variety of Hambella, like most Ethiopian coffee beans, belongs to Ethiopian local heirloom varieties, also known as Heirloom. You can usually see beans of varying sizes and shapes, possibly a mix of multiple varieties that have not been separately distinguished. This is because Ethiopia, as a treasure trove of coffee genetics, has an overwhelmingly large number of varieties that are extremely difficult to identify and classify. Additionally, the local government chooses not to disclose variety information for protection purposes, so they are collectively referred to as heirloom varieties.

Grinding Suggestions

Those who frequently make pour-over coffee certainly understand the critical impact of grind size on coffee extraction. Grind size mainly refers to the particle size of coffee grounds. Different particle sizes change the contact area with water. For example, the coarser the particles, the longer it takes for water to penetrate the coffee grounds and reach the center to extract soluble materials; the finer the particles, the shorter the time for water to reach the center. In other words, the coarser the coffee grounds, the lower the concentration; the finer, the higher the concentration. However, finer grinding is not always better—too fine can easily cause over-extraction, and bitterness will noticeably increase.

Regarding grind size selection, Front Street understands that everyone's grinding equipment is different. FrontStreet Coffee suggests using a Chinese No. 20 standard sieve and determining your grinder's setting based on the passing rate through the sieve, which also makes it easier to know which direction to adjust in future brewing. Sidamo Hambella is a medium-light roast. Front Street recommends targeting an 80% passing rate through the standard sieve. The EK-43 grinder used in Front Street stores is set to a grind setting of 5, which is a consistency like fine granulated sugar.

Of course, those without grinding equipment at home need not worry—Front Street can provide coffee grinding service. However, once coffee is ground, the aroma volatilizes much faster than whole beans. So friends who receive the coffee, remember to enjoy it as soon as possible!

Brewing Suggestions

To fully experience the rich aroma of Hambella, FrontStreet Coffee recommends using freshly roasted coffee beans for brewing, as this preserves the aromatic compounds to a greater extent. All coffee beans sold by Front Street are freshly roasted within 5 days. Combined with logistics and shipping time, by the time customers receive them, they are at their optimal tasting period and can be brewed and enjoyed directly.

To bring out the aromas of high-altitude coffee beans, Front Street chooses a relatively high water temperature to allow aromatic substances to be released more fully, but care must also be taken to avoid over-extraction. The recommended brewing parameters are as follows:

Dripper: V60

Water Temperature: 92-93°C

Grind Size: 80% passing rate through No. 20 standard sieve

Coffee-to-Water Ratio: 1:15

Coffee Dose: 15 grams

Natural Process Hambella

5.0

After grinding, you can smell rich tropical fruit aromas and honey-like sweetness. On the palate, it offers a full berry sweetness accompanied by complex aromas such as passion fruit, with a black tea-like mouthfeel and a long, lingering finish that is endlessly memorable.
