一直以来有许多小伙伴因为方便、不需要挑选咖啡豆，因此日常都会选择喝美式咖啡或者拿铁咖啡。 But in the past two years, I don’t know why the popularity of SOE suddenly blew away. Many friends said: “Now when I go to the store to order an American style, I have to choose coffee beans. It’s really annoying!” Then I asked FrontStreet Coffee (FrontStreet Coffee), what is the difference between SOE and ordinary espresso, and why most of them cost a few more dollars.
What is SOE?
S.O.E (Single Origin Espresso) single originEspresso指的是使用单一产区生产（Single Origin）的咖啡豆来做浓缩咖啡（Espresso），这与过往我们对espressoThe perception is somewhat different.
In the past, Italian coffee usually used dark roasted coffee beans and blended coffee beans from different production areas. The purpose was to give each cup of espresso a stable flavor, but it was often stronger. S.O.E's espresso coffee will be roasted according to the characteristics of the beans and uses coffee beans produced in a single production area, so drinking espresso is no longer the balanced bitterness and mellow taste we imagined.
SOEWill it taste better than regular espresso?
Not necessarily~ Both have their own advantages and disadvantages. The third wave of coffee has several characteristics: focusing on the freshness of coffee beans, lighter roasting of beans, using coffee beans from a single production area (producing area information is transparent), and placing more emphasis on the flavor description of coffee beans. Using single-origin coffee beans that are lighter roasted than blended beans to make espresso coffee can indeed make the coffee show a richer flavor, unlike blended coffee, which only has monotonous nuts and cocoa adjustability.
But not all lightly roasted single-origin coffee beans are suitable for making SOE. As a crop, the taste of coffee beans will vary depending on the annual climate and soil changes in the region. In addition, the flavor and tonality of each production area are different. The hand brewing method can show lemon-like acidity and the aftertaste of honey green tea, but it may become sour after pressurized extraction. The overall taste is thin and the body is not high.
The practice of blending coffee beans from different origins appears because using coffee beans from the same production area alone, the good and bad flavors in the coffee will be amplified by ultra-fine grinding and pressurized extraction by a coffee machine. Therefore, I thought of using coffee beans from different origins to have their own unique flavors, so as to complement each other's strengths and make the coffee after extraction more uniform.
FrontStreet Coffee believes that the advantage of SOE is that people who drink milk coffee can also feel the rich flavor of coffee. The disadvantage is that because coffee beans change every day, it cannot stabilize the stability of espresso for a long time, and the cost will be relatively high.
AndBlended coffee beansThe advantage is that even if the flavor of the coffee beans in the new production season changes, the espresso can continue to maintain a stable taste by adjusting the proportion. The disadvantage can only be stabilized through dark roasting, which will lose the rich flavor, but the cost will be relatively small.
How to extract SOE?
SOE的制作很考验咖啡师的萃取功力，需要考量咖啡豆的焙度，慢慢调整不同的Extraction parameters, showing the best extraction results, so there is no actual data for reference. FrontStreet Coffee has noticed in past experimental extractions that the extraction time and speed of single-origin coffee beans are often faster than those of blended coffee beans.
Therefore, when you want to adjust the extraction parameters of SOE, you must taste each espresso bean. If it feels too thin, it may be that the grinding is coarse/the amount of powder is too small/the amount of extraction is too large. If it is too strong/bitter, then it may be that the grinding is too fine/the amount of powder is too much/the amount of extraction is too small.
SOE coffee beans recommended
街咖啡门店虽然没有提供SOE的选择，但是日常也会尝试各种单品SOE的制作。 After countless experiments, FrontStreet Coffee recommends three single-origin coffee beans to make SOE:
"FrontStreet Coffee-Ethiopian Yirgacheffe sun-dried red cherry coffee beans" is an espresso extracted from lightly roasted coffee beans. The oil on the surface is fine and light, and the color is light yellow. It smells of sweet berries, and tastes not too irritating to the taste buds, with sweet and sour berries and caramel.
"FrontStreet Coffee - Costa Rica Mozart coffee beans" is medium roasted. The extracted espresso oil is fine and light, showing a light yellow color. It smells of raisins and tastes rich in sweet and sour flavor as well as fermented fruit.
"FrontStreet Coffee - Honduran sherry coffee beans" is medium roasted, and the extracted espresso oil has a creamy texture, is golden yellow, smells like whiskey, and tastes like vanilla cream and nutty caramel.
