For more specialty coffee knowledge, please pay attention to: FrontStreet Coffee
Front Street discovered that many people thought that SOE was a series of single-origin espresso made by directly applying single-origin beans to the extraction of espresso machines. It was not until they brought home various floral and fruit-flavored beans and tried them with a coffee machine that they discovered something was wrong. First, the following scene of squirting appeared, and then I was so shocked by the extremely concentrated acid that I didn't dare to take a second sip. Then I began to wonder if my equipment was too poor, or if there was an error in the operation.
In fact, the reason why you are unable to make the same SOE at home as in the store is probably not because of your equipment and technology, but because the roasting level of this coffee bean is not suitable for making espresso. FrontStreet Coffee Judging from the experience of coffee baristas, choosing a coffee bean that is suitable for SOE extraction will not only make delicious espresso easily, but also make American or latte coffee with twice the result by adding water or milk. There are two single-origin coffee beans on the Front Street Bean menu that have launched SOE versions, one is the Strawberry-flavored Front Street Oiran, and the other is the classic Yirgacheffe-flavored Front Street Kong with red cherry. We only need to check Italian roasting when placing an order.
Yirgacheffe coffee
Yirgacheffe has always been one of the most important coffee producing areas in Ethiopia. It was once part of the Sidamo coffee producing area, and later became an independent coffee producing area due to the unique flavor of Yirgacheffe coffee beans. It can be said that Yirgacheffe is not only the name of a coffee producing area, but also a noun describing a specific coffee flavor. The Yirgacheffe coffee production area is considered a high-altitude coffee production area, with an altitude of about 2,000 meters. There are more than 40 cooperatives in the Yirgacheffe coffee production area, which mainly manage coffee cultivation on a family business model.
There are many familiar micro-producing areas under the Yirgacheffe coffee producing area, such as Kocher, Foggy Valley, Godibey, etc. These micro-producing areas all have excellent cooperatives, and the Yirgacheffe coffee beans produced have their own unique flavor characteristics.
Front Street Yirgacheffe is dubbed a specialty coffee because of its light and translucent citrus-citric acidity and delicate floral and fruity aroma. Such significant flavor characteristics make Yirgacheffe not only the name of a coffee producing area, but also a symbol of a typical coffee flavor. Generally speaking, Yirgacheffe can be divided into two categories, which can be divided in terms of processing methods, namely Front Street sun-dried Yirgacheffe and Front Street washed Yirgacheffe. Today’s Front Street Coffee (FrontStreet Coffee), let’s talk about the differences between them. In addition to the obvious characteristics in appearance (less sun-dried silver skin and more washed silver skin), in terms of flavor, Front Street washed Yirgacheffe represents the most typical flavor characteristics of Yirgacheffe, while Front Street sun-dried Yirgacheffe adds a fermentation and sweet aroma to this.
Detailed recipe for SOE Yirgacheffe latte
The coffee machine in the Front Street store is a commercial single-head "Lelit Bianca" that can adjust the extraction by changing the pressure. The maximum pressure can be 11bar. A home coffee machine only needs to reach a pressure of 9 bar to meet the functions of extracting and frothing milk, and is paired with an espresso coffee grinder.
Sharing the extraction parameters of SOE coffee
Coffee Beans: Front Street Esai Sun-Dried Red Cherry Coffee Beans
Amount of coffee powder: 20g
Coffee liquid volume: 40g
Powder to liquid ratio: 1:2
Extraction time: 26~33 seconds
Grinding scale: Galileo 2.0 grid
Front Street uses a double powder bowl capacity, and the amount of powder is about 18 to 20 grams. When Front Street produces coffee, 20 grams of coffee powder is used.
Usually the ratio of coffee powder to coffee liquid is 1:1.5~1:2.5. The extraction ratio of Front Street is 1:2, that is, 20 grams of coffee powder extracts 40 grams of coffee liquid. The time is related to the flow rate of the coffee powder. Generally, the duration of a single extraction will be controlled between 20 and 35 seconds, because within 20 seconds, the coffee usually tastes thin, and if it exceeds 35 seconds, it will easily over-extract and produce a burnt and bitter taste. Most of the enrichments on Front Street are in the range of 28 to 30 seconds.
First, wipe the powder bowl dry, turn on the grinder, grind out a double amount of coffee powder, place it on the electronic scale and increase or decrease it to reach a weight of 20 grams. Then use tools to spread the powder evenly and fill the coffee powder cake tightly to ensure more stable coffee extraction. Then turn on the extraction switch and release water, moisten the brewing head and take away the stuck coffee grounds. Gently buckle the handle on the brewing head and start to pull down the brewing extraction. When the electronic scale shows that 40 grams of coffee liquid has been extracted, which takes about 28 to 33 seconds, you can pull the extraction switch and a cup of SOE espresso is completed. We can add a certain proportion of ice water or 80-degree hot water according to our own preferences to make a cup of Yirgacheffe SOE Americano coffee.
When making SOE hot latte, Front Street will use a ratio of 1:6. Add 40 grams of espresso liquid to the preheated coffee cup, and then use an espresso machine to steam 240g of milk. The milk temperature is best controlled between 50-65°C. It forms a dense and moderately thick milk foam, and then evenly blends it with the coffee liquid. The resulting Yirgacheffe SOE latte is like eating a lemon-flavored cookie. It has a rich and smooth taste, and the whole body feels warm after drinking it.
