In earlier years, when people mentioned black coffee, most would first think of Jamaican Blue Mountain. However, as the third wave specialty coffee movement gradually spread in China, the public's understanding of black coffee has moved beyond American-style coffee to more specific areas such as pour-over and single-origin coffee.

At Front Street stores, customers often ask for advice on selecting pour-over beans and about pour-over basics, such as how to set the water temperature and whether the grind should be coarse or fine. Next, Front Street will introduce the flavor characteristics of coffee beans from different origins.

Friends familiar with Front Street should know that our bean list includes a daily-bean series. Every bean in this series has been carefully selected by Front Street from numerous origins and can serve as a typical example representing a certain origin or processing method.

Based on Front Street's years of cupping experience, compared with post-processing methods such as natural and honey processing, washed processing best restores the truest taste of an origin. Therefore, the Front Street daily-bean series is mainly composed of washed beans. Of course, there are exceptions—Brazil uses semi-natural, and Indonesia uses wet-hulled, because semi-natural is a local traditional craft in Brazil, while wet-hulled is closely related to Indonesia's climate conditions and economic situation.

[Ethiopia]

Ethiopia is widely recognized as the birthplace of coffee and is also the first stop for many beginners. Among its regions, Yirgacheffe and Sidamo are the best known. In fact, Yirgacheffe originally belonged to the Sidamo region. Because its coffee has a unique jasmine floral aroma, it was later separated and upgraded to an independent main region.

In the 1970s, in order to improve green bean quality, the government introduced washed processing technology. Since then, coffee from the Yirgacheffe region has been mainly washed processed.

[Indonesia]

Among Indonesian coffees, besides the famous kopi luwak, Mandheling is also widely known. Mandheling's flavor and its processing method complement each other—wet-hulling created Mandheling, and Mandheling also made wet-hulling world-famous.

Indonesia's weather is changeable with frequent rainfall, and at the time economic conditions were limited, making it impossible to afford the cost of full washed processing. This gave rise to a unique semi-washed method—wet-hulling. Wet-hulling is divided into two drying stages. Before the second drying, when the coffee beans still have 50% moisture content, the parchment layer must be removed so the green beans directly contact the air for drying. It is precisely this step that gives Front Street Mandheling a fuller and smoother mouthfeel, with notes of herbs and spices.

[China]

After the movie Coffee or Tea became a hit, Yunnan coffee received unprecedented attention, and the Chinese people's enthusiasm for supporting domestic products was directly reflected in sales figures. China actually has three coffee-growing areas: Fujian, Hainan, and Yunnan. However, Fujian and Hainan are low-altitude coastal areas with relatively high temperatures and are not suitable for growing Arabica varieties. Specialty coffee cultivation is therefore concentrated in Yunnan. Front Street Yunnan small-bean coffee is rich but not bitter, aromatic but not harsh.

The coffee produced is mostly strictly hard bean (SHB grade), with outstanding sweetness.

Colombia has a mild climate and humid air, and its diverse climate conditions allow harvests throughout the year, with different periods, types, and regions ripening one after another. Colombian coffee has outstanding quality, a rich mouthfeel, and a long finish, making it truly specialty.

The Colombian coffee in the Front Street daily-bean series comes from the Huila region. This region is Colombia's most prestigious specialty coffee producing area, surrounded by mountains, with growing altitudes above 1,500 meters. The country's most important rivers converge here, bringing abundant moisture and water resources.

In the Front Street daily-bean series, the Guatemalan representative comes from the Huehuetenango region.

The Huehuetenango region is surrounded by three volcanoes, and the soil is rich in minerals. Altitudes can exceed 2,000 meters, and the coffee produced has a rich fruity flavor.

Brazil mostly uses sun-exposed cultivation, the fruit ripens quickly, and the beans are relatively soft.

Front Street has learned that some friends who are just getting into pour-over are curious: is pour-over coffee really better than coffee machine coffee? The coffee machine mentioned here usually refers to household or office American drip machines. American drip machines and pour-over share a similar principle, both using hot water to brew coffee grounds and then filtering. However, the dripping method of drip machines is preset by the manufacturer, and the output of machines from different brands also varies in taste.

Pour-over coffee is completely different. The dripping process is entirely controlled by human effort, and the pouring technique has a huge impact on the final flavor. Taking the one-pour method and the three-stage method as examples, the one-pour method is more outstanding in cleanliness and acidity, but the mouthfeel is relatively thin.

In addition, the flow rate when pouring also affects the flavor direction. When pouring with a small stream, the liquid level in the dripper rises only slightly, the coffee bed on the wall is thicker, the extraction time is lengthened, the coffee concentration increases, and the mouthfeel is fuller.

The circling speed also brings changes. When circling faster, the scouring force of the water increases, the coffee bed in the dripper tumbles more violently, and the extraction yield rises accordingly.
