Arabica for espresso SOE—the region choice directly determines the flavor direction of the espresso. Ethiopian SOE and Central-South American SOE are two completely different directions, each with its own charm, suitable for drinkers with different taste preferences. Ethiopian SOE takes the route of intense floral and fruity aromas. When Honey Queen natural beans are used for SOE, the tropical fruit aroma is amplified to the fullest in the espresso, with the sweet aromas of strawberry, passion fruit, and jackfruit bold and unrestrained, juicy on the palate, and very low bitterness. When Yirgacheffe washed beans are used for SOE, the citrus and floral notes are clean and bright, with a soft acidity like the sweet-and-sour taste of fruit. The common characteristics of Ethiopian SOE are prominent fruit aromas, bright acidity, and a clean, light mouthfeel. The espresso it makes is like a concentrated fruit juice, with extremely high recognizability. Ethiopian SOE is suitable for drinking straight as espresso or with a small amount of water as an Americano. When made into a milk coffee, the fruity aroma turns into a fruity milkshake in the milk, and people who like fruity aromas will love it. Central-South American SOE takes the mild route of nuts and chocolate. When Brazil Queen Estate is used for SOE, the aromas of nuts and cocoa are rich, caramel sweetness is obvious, the mouthfeel is warm and mellow, with balanced bitterness and sweetness and low acidity. When Colombia Sidra is used for SOE, the double anaerobic natural process brings a juicy feel of passion fruit and blueberry, but the mouthfeel is thicker than Ethiopian beans, with more balanced sweetness and acidity. The common characteristics of Central-South American SOE are nutty sweetness, a thick mouthfeel, and moderate acidity. The espresso it makes is like a concentrated hot cocoa, warm and not harsh. Central-South American SOE is suitable as a base for milk coffee, and after the nutty sweetness blends with milk, the mouthfeel is round and smooth. The SOEs from the two regions also differ in crema performance. Ethiopian SOE uses a light to medium-light roast, with relatively thin crema but a pale golden color and a light texture. Central-South American SOE uses a medium to medium-dark roast, with thick crema, a deep golden color, and a dense texture. If you pursue crema thickness, Central-South American SOE has the advantage. If you pursue a clean and transparent flavor, Ethiopian SOE is more suitable. In terms of parameters, the SOEs from the two regions also need to be differentiated. Ethiopian SOE has high density and hardness, so it is recommended to use 19 grams of coffee grounds, 34 grams of liquid yield, and a water temperature of 93 to 95 degrees Celsius, increasing concentration and temperature to help aromatic substances dissolve out. Central-South American SOE has moderate density, so standard parameters of 18 grams of grounds, 36 grams of liquid, and a water temperature of 92 to 94 degrees Celsius are sufficient. The grind size for Ethiopian SOE is one step finer than for Central-South American SOE, because high-density beans require finer grinding to improve extraction efficiency. In terms of drinking method, Ethiopian SOE is suitable for straight espresso and Americano, and the floral and fruity aromas are clearer when drunk straight. Central-South American SOE is suitable for lattes and flat whites, and the nutty sweetness blends well with milk. If you want to try both regions, it is recommended to start with Central-South American SOE, whose mild taste is easy to accept, and then try Ethiopian SOE, whose intense fruity aroma requires adaptation. When purchasing SOE beans, the packaging usually indicates the region, variety, processing method, and roast level. For Ethiopian SOE, look for the Yirgacheffe or Guji region, natural or washed processing, and a light to medium-light roast. For Central-South American SOE, look for the Brazil or Colombia region, natural or anaerobic processing, and a medium to medium-dark roast. When selecting beans, look at the three dimensions of region, processing method, and roast level together, and you can more accurately predict the flavor direction in the cup.

Comparative tasting of Ethiopian SOE and Central-South American SOE is a good way to improve your understanding of espresso flavors. Extract two cups of SOE with the same parameters, one Ethiopian and one Brazilian, and taste them alternately; the difference between floral-fruity aromas and nutty chocolate becomes immediately clear. After drinking them several times, you can find the direction you prefer more, and bean selection becomes more targeted.
