With the popularity of Italian coffee, SOE espresso has also become popular. Therefore, customers who come to Qian Street often ask questions related to "Can I choose beans for Italian coffee?" and "Is there any SOE coffee to choose from?"
what isSOEcoffee
The full name of SOE is "Single Origin Espresso", which is "single-origin espresso". As the name suggests, it is espresso made from coffee from a single origin. For example, if Front Street uses Front Street Essaya Gacheffe coffee beans to make espresso, it is calledSOE, and the English name of espresso is "Espresso”。But not all coffee beans are suitable for making SOE。
Because the espresso machine has a characteristic that it amplifies the original flavor of the coffee beans. For example, it only extracts the Ethiopian Yirgacheffe from Front Street. The flavor of this bean is citrus and lemon, which is relatively fresh. It is squeezed out by the espresso machine.SOEThe coffee will be particularly sour, or it can be extracted with Indonesian Mandheling from Front Street. The flavor of this coffee bean is characterized by herbal earthiness, so the extractedSOECoffee will be very bitter.
There are differences in roasting between SOE and single-origin beans produced on the market.。 For example, some coffee beans with obvious sour taste，In trickle brewing such as hand pouring，The roasting will be lighter，If used in an espresso machine，It will bake a little darker。So in theory, the SOE used for making espresso is not suitable for Pour over(V60) coffee.。Similarly, most lightly roasted coffee beans are not suitable for espresso machines, because they absorb water to a small extent and are prone to channel effects, so the flavor will naturally not be good.
SOEcoffeeCharacteristics
As mentioned above, the espresso coffee extracted by the espresso machine will deepen in flavor, soSOEEspresso beans from a single origin are generally not roasted too deeply. Therefore, compared with traditional darker roasted espresso beans, the flavor will be more difficult to extract, so the extraction parameters must be paid attention to.
On the other hand, for productionSOEWhen making a base of espresso, you need to adjust the ratio of espresso and milk or water. Reduce the milk or water to highlight the flavor of the coffee so that the coffee is not too bland. Finally choose to makeSOEThere are also very strict requirements on beans, althoughSOECoffee has outstanding performance, but because it comes from a single origin, its shortcomings are relatively easy to amplify, so factors such as roasting and particle size will affect the flavor.
Front Street’s previous article also said that coffee beans will be affected by weather, planting, roasting and other factors, which will cause subtle differences in the flavor of different batches of coffee beans every year. Therefore, these coffee beans from a single production area are used to makeSOECoffee, there is no guarantee that every cupSOEBoth have a stable flavor, which is why Front Street has not put it on the shelves.SOEThe reason for coffee, and the original intention of opening a cafe on Front Street was to allow coffee fans who come to Front Street Coffee to drink single-origin coffee with stable quality and regional flavor or high-quality espresso and milk coffee every time.SOEThe risk in terms of taste is too great. But that doesn't meanSOECoffee has no advantages, let’s talk about it in Front Street nextSOELet’s take a look at the pros and cons of coffee.
SOEAdvantages of coffee
SOEThe biggest advantage of coffee is that it belongs to the same "single origin" coffee beans as single-origin coffee, so it is purer in flavor, which is what Front Street said.EspressoCompared with the blended coffee beans, it will also have a clearer flavor layer.
SOEDisadvantages of coffee
The shortcoming is as mentioned in the previous article, it seems to be madesoeCoffee is very simple. You only need to replace the coffee commonly used for Italian coffee with single-origin coffee beans to make it. However, it is difficult to extract a delicious flavor, because in terms of roasting, you want to reflect the flavor of the coffee origin, and you use an Italian coffee machine. So the roasting of the coffee beans must be controlled well, not too dark, because once it is too dark, the flavor of the origin itself will be covered, but it cannot be roasted too lightly, which will makesoeThe acidity of the espresso is unbalanced, making extraction more difficult. Therefore high qualitySOECoffee also tests the skill of the roaster.
Secondly, as Front Street said, there are subtle differences in the flavor of each batch of coffee beans every year, and the pressurized extraction of espresso is also very sensitive to many factors, so the freshness and flavor differences of the coffee beans also affect the extraction.SOEa factor. It is precisely because of these reasonsSOEThe price of coffee will also be higher thanespressoMuch more expensive.
The above is compiled by Front StreetsoeAn introduction to coffee, I believe all coffee fans will be familiar with it after reading this article.soeNow that I have a deeper understanding of coffee, and Front Street’s article also mentioned the blending of coffee beans for Italian coffee, let’s make a supplementary introduction to coffee blending on Front Street.
What is coffee blend
The article on Front Street also said that blended coffee is mainly used for common dishes such as mocha and latte.espressoThe purpose is to optimize the flavor of coffee. Generally, blended coffee is a blend of two or more different types of coffee beans. Only coffee beans roasted into coffee beans suitable for use in espresso machines are calledespresso beans。
Of course, this kind of comprehensive coffee beans cannot be produced casually, but through the blender's unique understanding of coffee flavor, different coffee beans can complement each other to create a blend of coffee beans with excellent flavor.
like1：1The blending of coffee beans from the two production areas will definitely have a dark and weird flavor, so there are strict requirements on the proportion of coffee beans. For example, Front Street’s blending idea is to blend into another coffee with a unique flavor based on acidity, bitterness, sweetness, aroma and alcohol.
For example, the Front Street store also has four types of Italian blended coffee beans, each with its own characteristics. They are all the best blends of flavored coffee beans selected by Front Street roasters through extensive blending tests.
Among them is the Front Street Sunflower Warm Sun blended coffee bean. When used to make espresso, this bean will emit a clear aroma of fermented wine. When you taste it, the acidity of citrus and berries will immediately emerge, with the aroma of whiskey, and the aftertaste is dark chocolate. Its ingredients are Front Street Yirgacheffe sun-dried red cherries and Front Street Honduran sherry7：3proportions.
Therefore, Front Street recommends that coffee fans who are pursuing Italian coffee with a stable flavor should choosesoeFor coffee, blending coffee beans would be a better choice and also more cost-effective.
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 due to 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 can not only make delicious espresso easily, but also add water or milk to make American or latte coffee with twice the result with half the effort. 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 SOE, and the other is the classic Yirgacheffe-flavored Front Street Essekonga SOE. We only need to check Italian roasting when placing an order.
