Introduction:An in-depth exploration of Ethiopia’s Guji-Hambela region’s sun-dried king — the Huakui 5.0. From the exquisite processing techniques at Buku Able, the unique microclimate of the producing area, to the roasting profile and V60 brewing parameters, this article provides a comprehensive breakdown of this G1-grade sun-dried coffee that boasts both strawberry cream sweetness and blackcurrant richness. Here, you’ll gain complete knowledge from the green bean characteristics to the flavor profile, along with a professional-grade pour over brewing guide.

In the brilliant map of Ethiopian specialty coffee, the Guji-Hambela region first gained attention with a 2017 TOH (Taste of Harvest) sun-dried competition champion bean, marking the legendary beginning of the Huakui series. This sun-dried G1 coffee from Buku Able has now evolved to the Huakui 5.0 version, and with its intense fruit aroma and full-bodied taste, it has become a favorite among many coffee enthusiasts.

Many coffee drinkers mistakenly assume Ethiopia only produces bright, acidic coffees due to the renowned acidity of Yirgacheffe. However, Guji actually showcases a distinctly bold and rich flavor profile. As a neighboring region to Yirgacheffe, Guji features diverse coffee-growing environments — from high mountains to deep valleys — along with a wide variety of native coffee varieties, resulting in richly layered flavors.

The origin of Huakui 5.0, Guji-Hambela, was originally part of Sidamo until 2010 when it was designated as an independent producing region by the Ethiopian Commodity Exchange (ECX). Located southeast of Yirgacheffe, the area has a complex and varied terrain, encompassing towering mountains, deep valleys, and expansive plains, with altitudes generally exceeding 1800 meters. Combined with fertile black soil (Vertisol) and significant diurnal temperature variations, these conditions provide an ideal environment for cultivating high-quality coffee.

When speaking of Huakui, one must start with its glorious beginning — the 2017 TOH (Ethiopia National Taste of Harvest Competition) sun-dried category competition. That year, a sun-dried lot from Buku Abel processing station, submitted by DW Coffee Company, won the championship with its intense berry aroma and creamy smooth texture. These beans were the origin of the Huakui series. Later introduced to China by traders and named “Huakui,” meaning “the king among a hundred flowers,” the name symbolizes its exceptional and peerless flavor.

Buku Able processing station is located in Buku Abel village at an altitude of about 2200 meters. The region’s unique microclimate and soil conditions lay a solid foundation for coffee growth. The coffee trees are planted in nutrient-rich reddish-brown soil and enjoy moderate shading, which helps the fruits accumulate flavor compounds while avoiding excessive nutrient consumption. The main harvest season is from December to January, during which only fully ripe red cherries with a sugar content of 30 or above are selected for sun-drying.

During processing, Buku Able strictly controls the fermentation environment: in the first two days of sun-drying, appropriate humidity is maintained to promote fructose fermentation, with shading applied during midday high temperatures to prevent overexposure; cooler nighttime temperatures help preserve aroma and acidity. Coffee farmers handpick only fully red cherries and use African raised beds for drying. Careful control of drying bed thickness and 24-hour regular turning ensure even drying, allowing the sugars in the mucilage to fully penetrate the beans, creating the signature sweet flavor of the Huakui series.

Since its debut in 2017, the Huakui series has successively released versions 2.0, 3.0, 3.1, and more, until 2021 when it was officially divided into two main lines: “Small Bean Huakui” and “Huakui 5.0.” Huakui 5.0 continues the tradition of high-altitude sun-dried processing while continuously refining bean selection and processing details. This particular lot comes from Guji-Hambela, processed by Buku Able processing station at an altitude of 2350 meters. The variety is Ethiopian Heirloom, processed using traditional sun-drying methods, showcasing ultimate fruitiness and sweetness.

In terms of roasting, this native variety coffee varies in bean size, so special attention must be paid to even moisture removal during drying. Industry roasters, when handling the new-season Huakui 5.0, extended the drying phase appropriately due to the higher-than-average moisture content of the green beans, ensuring synchronized development of the bean surface and core. To highlight its bright berry notes and floral-fruity aromas, a medium-light roast level was ultimately chosen. Roasting began at 196°C, with a first crack development time of 1 minute and 40 seconds, giving the coffee a rich profile and a clear, sweet flavor structure.

Cupping results show that Huakui 5.0’s dry fragrance carries fresh citrus and berry notes, while the wet aroma reveals intense blackcurrant and rose fragrances. Upon tasting, flavors of almond, strawberry, and blackcurrant intertwine, accompanied by noticeable fermentation character. The sweetness is long-lasting, and the aftertaste leaves a honey-like lingering finish. These characteristics make it not only ideal for single-origin enjoyment but also an excellent choice for pour over enthusiasts.

It is recommended to use a V60 #01 filter cone for brewing, with water temperature controlled at 90–91°C, a coffee-to-water ratio of 1:15, and a grind size of about 77% passing through a #20 sieve (similar to granulated sugar). Specifically, start with a 30-second bloom using 30 grams of water, then pour in a small circular motion up to 125 grams for the first pour, followed by a pause once the water level is about to expose the coffee bed, then continue pouring to 225 grams. Total brew time is approximately 2 minutes and 5 seconds. These parameters fully showcase Huakui 5.0’s high-temperature almond aroma, and as the temperature drops, bring out the berry acidity and sweetness along with the rich mouthfeel akin to blackcurrant juice.

In summary, Huakui 5.0 not only inherits the unique terroir charm of the Guji-Hambela region but also, through the refined craftsmanship and strict quality control of Buku Able processing station, achieves a sun-dried G1-grade coffee bean with distinct flavors and rich layers. Whether you’re a beginner exploring Ethiopian coffee or a seasoned connoisseur chasing ultimate flavor, you can experience the unique charm of high-altitude sun-dried coffee through this Huakui 5.0.
