What Does SOE Coffee Mean for Espresso Drinkers?

SOE stands for Single Origin Espresso, meaning espresso extracted from single-origin beans rather than a blend. The method highlights one bean's flavor personality. Geisha is a common choice because its floral aroma and delicate fruity acidity come through under pressure. Espresso machines use pressure and very fine grounds, so they tend to amplify whatever character the bean already has.

The soe in coffee meaning matters for bean selection: light-roast pour-over beans are not suited to direct espresso use, since pressure extraction can cause under-extraction and sharp acidity. High-altitude Geisha, grown with cloud cover or shade trees and fertile soil, works better. Panama's Hacienda La Esmeralda sits at the top of the grade range, while Ethiopian Geisha offers citrus and floral notes at a lower price.

Front Street Coffee has previously shared a method for brewing pour-over with blended beans. This time, let's take a different approach and use single-origin beans to make SOE. SOE stands for Single Origin Espresso, where single-origin coffee beans are used to extract espresso, better showcasing the bean's inherent flavor personality. When it comes to the most famous coffee variety, Geisha is undoubtedly on the list. If Geisha were used to make espresso, what kind of taste experience would it present? This article will focus on the bean selection approach for Geisha SOE, roasting degree requirements, and specific extraction steps, along with Americano and Latte ratio plans, to guide you through mastering the making of this exquisite single-origin espresso.

Front Street previously published an article on making pour-over with blended beans, so today we'll do the opposite and use single-origin coffee to make SOE. SOE means Single Origin Espresso, which is using pour-over single-origin coffee to extract espresso, highlighting the distinctive flavors of a particular bean. When it comes to the most well-known coffee variety, Geisha must be mentioned. So, if Geisha were used to make espresso, what flavor would it have?

Although the Geisha variety has a delicate flavor, such elegant flavors come from specific growing environments. The Geisha variety is very particular about its growing conditions; the coffee trees require high altitudes, cloud cover or plenty of shade trees, and fertile soil. High-altitude Geisha coffee has pronounced floral aromas and delicate, elegant fruity acidity, and these layered advantages are a big reason it has become popular worldwide.

Today, Geisha is grown in almost all coffee-producing regions around the world, with the two most representative countries being Panama and Ethiopia. In terms of grade, there's Panama's Hacienda La Esmeralda; in terms of value for money, Ethiopian Geisha coffee offers the bright citrus and floral flavors brought by its origin, and with its approachable positioning, it is more suitable as an everyday staple coffee.

Because espresso machines use pressure extraction and the coffee grounds are ground very fine, it is easy to amplify the coffee's own characteristics. It is not suitable to directly use light-roasted pour-over beans, otherwise it may result in under-extraction, sharp acidity, and other consequences.

For this reason, when making SOE, priority should be given to single-origin coffee with a medium roast, which allows for more stable extraction.

If you want to taste the unique floral and fruity flavors of the Geisha variety in espresso, buy Front Street Granada Geisha SOE. It comes from Ethiopia, the birthplace of coffee, uses traditional natural processing, and has the sweet-tartness of ripe fruit. Because it uses a medium roast, it retains the fragrance of floral notes while also highlighting caramel notes, and gives the espresso a moderate crema. Below is how to make a standard Geisha SOE coffee:

Coffee beans: Front Street Granada Geisha SOE

Coffee grounds: 20g

Coffee liquid: 40ml

Ground-to-liquid ratio: 1:2

Time: 25–30 seconds

The coffee machine used by Front Street has a double-shot basket capacity, requiring 20 grams of coffee grounds each time. The extraction ratio of grounds to liquid is 1:2, meaning 40 grams of coffee liquid is produced within a reasonable time.

Before extraction, we need to first wipe the basket dry, turn on the grinder, grind a double dose of coffee grounds, place them on an electronic scale to measure and adjust until there is exactly 20 grams. Then use a distribution tool to level the coffee grounds, and use a tamper to press vertically downward with force to tamp the coffee puck firmly, ensuring more stable extraction.

Then turn on the extraction switch and let water run for 1–2 seconds to wet the group head, which also removes any stuck coffee grounds. Place an electronic scale under the cup that will catch the Espresso, and tare it to 0. During extraction, place it together under the group head.

Gently lock the portafilter onto the group head and start the extraction switch. Observe the changes in the extracted liquid. When the electronic scale shows 40 grams of coffee liquid extracted, at about 30 seconds, turn off the extraction switch.

Pour the extracted 40g of Front Street Granada Geisha SOE coffee liquid into a coffee cup. Add 160g of ice water or warm water at a 1:4 ratio to make a refreshing SOE Geisha Americano. If you like lattes, you can also add 240g of steamed fresh milk at a 1:6 ratio to soften the taste, making a delicious SOE Geisha Latte.
