espresso coffee is how to extract espresso coffee extraction principle characteristics taste

The little friends of lattes who have tried the front street coffee will ask in doubt: this coffee really does not have alcohol. Unfortunately, Qianjie coffee really only sells coffee, there is really not a drop of wine in the coffee, and the attractive aroma of Qianjie coffee is because the Italian beans of Qianjie coffee are made of coffee beans fermented in buckets.

After hearing that the Italian coffee beans in the front street are so unique, many friends want to find out that in order to verify the wine smell in the coffee beans, they will really order a cup of espresso. However, not everyone can accept the taste of espresso.

Because the production method of espresso is to grind the coffee beans into a fine powder, and then squeeze the high-temperature hot water through pressed powder under high pressure to extract the espresso liquid, the finished product is very rich and sticky. Since it is concentrated, it means that the coffee is so thick and so concentrated that most of it needs to be diluted with milk or water before it can be accepted.

In fact, thanks to the development of science and technology, we can want to use such unique coffee. As early as the beginning of the 20th century, European people drank espresso almost the same as the coffee brewed in today's mocha pots. Boiling hot water, ultra-low extraction pressure near atmospheric pressure, and long extraction time, Italian coffee at that time was characterized by thin taste and obvious bitter taste, similar to what people often call "boiled water." It was not until 1961, when Pegasus launched the Faema E61 espresso machine, that the definition of espresso began to be very close to that of espresso as we know it today.

Those who have ordered espresso in Qianjie should have experienced it. Qianjie will produce espresso with a cup of ice water and a small spoon. So, what's the right way to drink espresso? What is the use of ice water and small spoons? Is espresso directly poured into ice water and stirred with a small spoon?

When a partner orders espresso and pours espresso liquid into ice water, there is a good chance that baristas in front of the street will stop it. What about espresso? How did it become iced American coffee?

Half of espresso drinks take a sip of ice water to clean your mouth and get ready for espresso before drinking it. Small spoons can be used or not, small spoons can be used to check the oil of espresso and stir espresso evenly.

First, drink a mouthful of ice water to clear the taste in the mouth.

Second, insert a small spoon into the cup to check the status of the grease.

Third, first sip the espresso, let the coffee liquid stay in the mouth, and fully feel the flavor and taste of the espresso liquid with your tongue.

Fourth, before drinking another sip of espresso, you can drink another sip of ice water to feel the different taste of espresso from top to bottom.

The espresso beans of Qianjie Coffee have a strong aroma of wine, because the sunflower sunflower coffee beans used in Qianjie stores are made of 70% Honduran sherry coffee beans and 30% Ethiopian sun-tanned cherry coffee beans.

Qianjie Coffee Sunflower with Coffee beans

Producing area: Honduras & Ethiopia

Varieties: Kaddura, Kaduai, Pacas, native species

Treatment: washing and insolation

Honduran sherry coffee beans are fermented at a low temperature in a whisky barrel for 30 to 40 days, allowing the sweet taste of sherry whiskey to seep into the raw coffee beans. Ethiopian sun red cherry coffee beans use the most traditional and primitive sun treatment, which gives coffee beans a stronger sense of fruit sweetness.

Different beans need to use different cooking parameters, different time periods, different humidity, will lead to a series of parameters such as grinding degree to change.

[powder quantity] the amount of powder is generally determined by the size of the powder bowl, while the size of the powder bowl used in Qianjie stores is 20 grams, so it also uses 20 grams when it is produced.

[ratio of powder to water] with the coffee extraction going on, the substance is precipitated, and the coffee substance extracted is becoming less and less. The more the front part of the coffee extract, the more concentrated the flavor and the thicker the taste.

[time] the flavor substances in coffee begin to react when they come into contact with water, sour substances and sweet substances are first extracted, and with the passage of time, bitter substances in coffee begin to come out. The time for Qianjie to extract espresso is between 26 and 28 seconds.

[grinding degree] the finer the coffee powder, the larger the contact area between the powder and water, and the more flavor substances extracted. Too fine will lead to the risk of over-extraction; too coarse will lead to insufficient acidity and even a sense of water.

After adjusting the parameters in Qianjie, when using this Italian bean to produce espresso, it will take 20 grams of coffee powder to extract 40 grams of espresso, and the extraction time is about 27 seconds.

Its flavor has a strong whisky aroma, with sour berries, with a slight drop in temperature, vanilla, cream flavor began to emerge, dark chocolate aftertaste, overall uniform, full-bodied and smooth taste.

Some friends who often drink hand-brewed coffee may think carefully, since it is Honduras Shirley with Ethiopian sun-tanned cherries, then buying a bag of Honduran Shirley hand-brewed coffee beans and a bag of Ethiopian sun-red cherry hand-brewed coffee beans will solve the problem of espresso coffee as well as hand-brewed coffee, won't it?

You really can't have this idea. The roasting of coffee beans is the same as cooking. Dishes cooked with gentle fire and martial fire also taste different. In the front street, when roasting Honduran Shirley hand-flushed coffee beans and Essex sun-red cherry hand-washed coffee beans, in order to highlight their acidity and aroma, light to moderate roasting is generally used. When used in the production of Italian coffee beans, in order to make the taste thick and smooth, rich aroma, generally use the degree of medium-depth baking.

Therefore, if you want to buy two types of hand-made coffee beans to mix at home, you can't get the taste of Qianjie store. So, can this Italian coffee bean be used to make hand-brewed coffee? Qianjie thought about this when designing this espresso, so this sunflower can meet the needs of making espresso and hand-brewed coffee.
