How Do You Pull a Yirgacheffe SOE Latte at Home?

Single-origin beans straight from the bag often spray or turn out sharply sour, because the roast level, not the machine, decides whether espresso works. Front Street lists two beans with an espresso roast option: Huakui with strawberry aroma and Konga Red Cherry with the classic Yirgacheffe profile. Choosing the right roast is what makes a drinkable SOE.

Using Front Street Ethiopia Natural Konga, the walkthrough covers grind setting, coffee-to-liquid ratio, extraction time, and steaming dense milk foam to combine with the shot; the finished soe latte tastes like a lemon cookie, rich and smooth. The same shot can be diluted into a soe americano, so one bean and one set of parameters cover both drinks.

Many people think that putting single-origin beans directly into an espresso machine will produce an SOE, but the result is either splattering or acidity so sharp it's undrinkable. In fact, the problem usually lies in the roast level—not all single-origin beans are suitable for espresso. On the Front Street Coffee bean list, there are two SOE versions available: the strawberry-scented Front Street Huakui and the classic Yirgacheffe-flavored Front Street Konga Red Cherry. Just check the espresso roast option when ordering. This article uses Front Street Ethiopia Natural Konga as an example to share in detail the complete process for making an SOE Yirgacheffe latte, including key parameters such as grind setting, coffee-to-liquid ratio, extraction time, and how to steam dense milk foam and blend it with the espresso. The resulting latte tastes like a lemon-flavored cookie at first sip—rich, fragrant, and smooth—and leaves you feeling warm all over after drinking it.

Front Street has noticed that many friends mistakenly believe SOE simply means putting single-origin beans directly into an espresso machine to extract a single-origin espresso. As a result, they take home those beans with floral and fruity notes and give it a try, only to find the situation is completely wrong. First comes a splattering gush, then the shock of espresso so sour they dare not take a second sip, and afterward they begin to question whether their equipment is not good enough or something went wrong in their process.

In fact, the reason you can't make café-quality SOE at home often isn't the equipment or technique—it's that the roast level of the beans in your hands simply isn't suitable for espresso. According to the practical experience of baristas at Front Street Coffee (FrontStreet Coffee), choosing a bean suitable for SOE extraction not only lets you easily get a delicious espresso, but also makes it straightforward to add water or milk afterward for an Americano or latte. On the Front Street bean list, two single-origin beans offer SOE versions: one is the strawberry-aroma Front Street Huakui, and the other is the classic Yirgacheffe-flavored Front Street Konga Red Cherry. Just check the espresso roast option when ordering.

Yirgacheffe Coffee

Yirgacheffe has always been one of the most core coffee-producing regions in Ethiopia. It originally belonged to the Sidama region, and only later, because Yirgacheffe coffee beans had such a unique flavor, was it separated into its own region. It can be said that Yirgacheffe is not just a place name, but also synonymous with a specific coffee flavor. This region is a high-altitude area, at about 2,000 meters above sea level. Within the Yirgacheffe region there are more than forty cooperatives, and coffee cultivation is basically managed through family-run operations.

Under the Yirgacheffe region there are also many micro-regions familiar to everyone, such as Kochere, Misty Valley, Gedeb, and others. These micro-regions all have outstanding cooperatives, and the Yirgacheffe coffee beans they produce each have their own unique flavor personality.

The reason Front Street Yirgacheffe is praised as specialty coffee is its light, transparent citrus-lemon acidity and delicate floral-fruity aroma. Such distinctive flavor characteristics make Yirgacheffe not only the name of a region, but also a symbol of a typical coffee flavor. Overall, Yirgacheffe can be divided into two major categories by processing method: Front Street Natural Yirgacheffe and Front Street Washed Yirgacheffe. Today Front Street Coffee (FrontStreet Coffee) will talk about the differences between the two. Apart from the obvious differences in appearance (natural has less silver skin, washed has more silver skin), in terms of flavor, Front Street Washed Yirgacheffe represents the most typical flavor characteristics of Yirgacheffe, while Front Street Natural Yirgacheffe adds an extra layer of ferment character and sweet aroma on top of that.

Detailed Method for SOE Yirgacheffe Latte

The coffee machine used at Front Street's shop is a commercial single-group "Lelit Bianca," which can adjust extraction by changing pressure, with a maximum pressure of 11 bar. As long as a home coffee machine can reach 9 bar pressure, it is enough to meet the needs of extraction and milk frothing, and pairing it with an espresso grinder is all you need.

Sharing SOE Coffee Extraction Parameters

Coffee beans: Front Street Ethiopia · Natural Konga

Coffee grounds: 20g

Coffee liquid: 40g

Grounds-to-liquid ratio: 1:2

Extraction time: 26–33 seconds

Grind setting: Galileo 2.0

Front Street uses a double basket with a capacity of about 18–20 grams, and for output Front Street will take 20 grams of coffee grounds.

The ratio of coffee grounds to coffee liquid usually falls between 1:1.5 and 1:2.5. Front Street's extraction ratio is 1:2, meaning 20 grams of grounds extract 40 grams of liquid. Time is related to the flow rate of the coffee grounds, and generally a single extraction is controlled within 20–35 seconds. Because within 20 seconds the coffee taste is often too thin, while over 35 seconds it is prone to over-extraction and burnt bitterness. Front Street's espresso mostly falls in the 28–30 second range.

Front Street first wipes the basket dry, turns on the grinder to grind a double dose of coffee grounds, and places it on the electronic scale to adjust until it reaches 20 grams. Next, use a tool to distribute the grounds evenly and tamp the puck firmly to ensure more stable extraction. Then turn on the extraction switch to release water, wetting the brew head while carrying away residual coffee grounds on it, gently lock the portafilter onto the brew head, and flip the switch down to begin extraction. When the electronic scale shows the coffee liquid has reached 40 grams and the time is about 28–33 seconds, you can pull the switch down, and a cup of SOE espresso is complete. Afterward, depending on personal preference, add an appropriate amount of ice water or 80°C hot water to make a cup of Yirgacheffe SOE Americano.

When making an SOE hot latte, Front Street uses a 1:6 ratio. First pour 40 grams of espresso into a preheated coffee cup, then use the espresso machine steam to froth 240g of milk, preferably controlling the milk temperature between 50-65°C so the milk foam is dense with a moderate thickness, and then fully blend it with the coffee liquid. The Yirgacheffe SOE latte made this way tastes at first sip as if you are eating a lemon-flavored cookie, with a rich, fragrant, and smooth mouthfeel, and after drinking it your whole body feels warm.
