SOE, short for Single Origin Espresso, refers to espresso made from coffee beans of a single origin. Its greatest charm lies in its ability to clearly present the terroir of the origin—one sip lets you identify where the beans come from, what variety they are, and what processing method was used. However, the high-temperature, high-pressure operation of an espresso machine multiplies and amplifies the flavors; when light-roasted beans are used for SOE, the fruity acidity can easily become sharp and astringent, so everything from bean selection to setting extraction parameters to pairing with drinks requires extra care. Compared with traditional blended beans, SOE indeed has a higher extraction threshold, and choosing the right single-origin bean often yields twice the result with half the effort. Starting from the characteristics and story of SOE, this article will sort out the extraction standards for a good Espresso, and, using three Front Street Coffee beans—Brazil Queen's Estate, PWN Golden Mandheling, and Huakui—as examples, share specific parameters and methods for making iced and hot Americanos and lattes.

In espresso preparation, the interplay between grind size and extraction time directly determines the quality of the flavor in the cup. The essence of extraction is using water to draw out the soluble substances from the coffee grounds; the longer the time, the more is dissolved, but not all substances are worth releasing. Therefore, finding the right extraction window is crucial. This article will focus on four key elements: the double basket, weighing instead of measuring by volume, a 1:2 coffee-to-water ratio, and an extraction range of 25 to 30 seconds, helping enthusiasts understand how to control the flavor direction of espresso by adjusting the grind. The article also combines the practical experience of Front Street Coffee to offer actionable parameter recommendations. [more…]
