What does SOE coffee mean next to single-origin labels?

SOE stands for Single Origin Espresso: espresso pulled from beans of one single origin, as opposed to an espresso blend. Single-origin coffee itself means beans from one place, and the label usually lists growing location, altitude, processing method and variety so drinkers can trace the flavor back to a specific farm or region.

Specialty coffee adds a quality angle, pointing to beans grown in distinct microclimates that carry a clear taste of place. As buyers showed willingness to pay more for such lots, producers focused harder on source, and soe coffee beans moved from filter brewing into espresso, helped along by competitions and chain brands.

Single-origin coffee is a high-frequency professional term in coffee circles, usually referring to coffee beans from a single origin. The label will indicate information such as growing location, altitude, processing method, and variety, helping drinkers more clearly perceive the flavor characteristics. Specialty coffee, on the other hand, emphasizes the positive aromas and "taste of place" formed under unique microclimates and geographical conditions. As consumers deepen their understanding of origin information, producers devote more energy to the source of specialty coffee, and thus single-origin beans emphasizing a single origin emerged. This article will sort out the common extraction methods for single-origin coffee, the relationship between SOE and blended beans, the impact of roasting and freshness on flavor, and ideas for parameter adjustment when making SOE at home, while retaining Front Street Coffee's bean selection and shipping suggestions.

Single-origin coffee, a specialized term that has frequently appeared in coffee circles in recent years, can be simply understood as coffee beans from a single origin. Their labels often carry relatively detailed source information, such as growing location, altitude, post-processing method, variety, etc., allowing tasters to better experience and understand the flavor and taste characteristics of this coffee.

So-called specialty coffee comes from producing regions with unique microclimates and geographical conditions, cultivating high-quality coffee with positive aromas and a "taste of place." As more and more consumers learn about the origin information of coffee beans and are willing to pay higher prices for high-quality coffee beans, producers naturally devote more energy to the source of specialty coffee, and thus single-origin coffee beans emphasizing a single origin appeared.

At first, single-origin coffee beans were generally only used to extract black coffee by methods such as pour-over, siphon, and French press. Later, more and more single-origin beans were applied to espresso, and with the promotion of various competitions and chain brands, a concept called "SOE" began to become increasingly popular. SOE is the acronym for Single Origin Espresso, translated as espresso made from single-origin coffee beans, corresponding to espresso blends. The proposal of SOE came along with the popularization of the concepts of specialty coffee and single-origin coffee brought by the third wave of coffee.

Traditionally, coffee beans from a single origin are usually used for drip coffee, such as pour-over coffee. Pressurized espresso uses blended beans as raw material. Producers combine coffee beans from different origins and use dark roasting to highlight a rich, mellow, and bitter taste, with flavors basically fixed in the tone of caramel, dark chocolate, nuts, and cocoa.

As people's pursuit of coffee grows higher and higher, single-origin coffee beans are not only presented in the form of pour-over. People have begun to extract single-origin beans with unique flavors in various ways in order to obtain clearer single-origin coffee characteristics. Some coffee shops charge an extra price difference for SOE coffee beans, and many friends therefore think that SOE is more premium than blends and tastes better. From the above, it is not difficult to see that SOE only indicates that the coffee beans come from a single origin, so it does not mean the coffee quality is better, nor does it mean the taste is necessarily better than a blend.

Single-origin beans used for pour-over need to present the unique regional flavor of the origin and the aroma of the coffee beans themselves, just as Yirgacheffe has fresh and bright citrus and lemon acidity, and Blue Mountain coffee should have sweet chocolate and caramel aromas. Similarly, SOE should also express the flavor characteristics that the origin should have. If the roast level is too dark, the flavors and aromas are easily covered by the heavy substances produced after roasting; if the roast is too light, it easily leads to under-extraction, resulting in sharp acidity and a thin taste. Therefore, whether a cup of SOE coffee tastes good greatly tests the roaster's and barista's "interpretation" of SOE.

If we are making SOE at home, Front Street suggests using single-origin beans with medium or medium-dark roasting for extraction, which can avoid the strong, stimulating taste brought by roasting factors. For example, Front Street Brazil Queen's Estate coffee beans use medium-dark roasting, and the extracted SOE presents chocolate, roasted hazelnut, cream, and a sugarcane-like sweet aftertaste.

No matter how a coffee bean is extracted, Front Street believes freshness is crucial. If coffee beans with a roast date more than one month ago are used, part of the aroma may already have been lost, and an unpleasant woody taste may have developed. Front Street hopes that every customer who places an order can taste the coffee's aroma during the best flavor period, so it ensures that only beans freshly roasted within 5 days are shipped. If everyone wants the SOE coffee they make to have better flavor, Front Street suggests choosing freshly roasted single-origin coffee beans.

When we use coffee beans with a lighter roast level to extract SOE, because the coffee beans have been roasted for a shorter time, their internal texture is still relatively hard, making the flavor harder to extract. Therefore, extraction parameters need to be adjusted to increase the extraction yield, such as extending the extraction time, increasing the water temperature, making the grind finer, and increasing the dose.

The fineness of espresso grinding is much higher than the grind size for pour-over drip coffee. Adjustments should not be too large, as this can easily lead to excessive variables and more unstable extraction. Front Street is for daily store output, so parameter adjustments are based on accumulated daily experience. If our at-home output is relatively low, it is harder to grasp, and Front Street suggests recording it and summarizing more about the relationship between extraction parameters and flavor performance. This will help us adjust quickly and also save unnecessary waste.
