The knowledge of Espresso

"Espresso" is an Italian coffee bar, which means on the spur of the moment and "for you" (cooked for you now). It is also possible that it is not appropriate to translate it into "grilled coffee".

What is Espresso? If you get up, you will get many different answers. It is true that through the development of & # 3900, Espresso has become a kind of life and art.

There is a tendency that the birth time of espresso is around & # 39; and this year is regarded as the official birth year of espresso. Since then, this special coffee sauce has been popular in Italy, Spain, Portugal and other countries in South Africa. But it wasn't until 39 years ago that espresso was pushed around the world by Starbucks. It was only after that that people in the coffee industry around the world began to understand and understand this kind of coffee. It is only a decade or so earlier than the time when Chinese people received espresso. So the more popular and reasonable way to name it is espresso.

Espresso is a kind of coffee brewing.

Espresso is a technological method of brewing coffee. According to the definition of "EspressoCoffee The Chemistry of Quality", it must meet the following conditions:

The amount of coffee powder (one cup). ±& # 39. Gram

Degree of water (℃) 0 °±°

The force of water (bar)

0 ±seconds out of time

Degree of water: if the water is too low, it will cause insufficient extraction, and the contents of the coffee can not be fully released, so that you can only cook a cup of Espresso; with insufficient taste and sour taste. Once the water is too high, the excessive extraction will make the coffee bitter and bitter.

The power of water: the general boiling water bubble method can only extract water-soluble substances in coffee, while Espresso can further extract water-insoluble substances by high temperature. These high levels will completely emulsify the Lipophilic Substances inside the coffee and dissolve it into the water, which is the main source of "body".

[P.S.] emulsification will make Espresso taste sticky and make people drink with a feeling of "smooth and soft", and the stickiness will form a low surface strength, which can invade the taste buds and make the mellow taste back in the mouth for a long time.

Out of time: the length of time will affect the amount of water produced, and Espresso will extract the taste of coffee with high water, about; it will take a second to complete the task (after this time, the liquid will become tasteless and will only dilute Espresso). After the timeout, some people still let it out of the water and drip a cup to form a "Americano" or "Lungo", which tastes like charcoal coffee.

Espresso is a life.

In Italy, Espresso is the life concerto of the people. In the morning, we first have a Latte; after that, people like to go to the store to drink Espresso, and everyone waits at the bar. After getting the first-hand coffee, we drink it in three sips. The guests in the shop know each other, and the coffee maker (Barista) also participates in the chat, so the coffee shop becomes a coffee shop.

In the United States and Taiwan, Italian coffee stands on the streets, and it is a place for young people to chat. Most of them don't drink Espresso, only cappuccino or cappuccino with milk. In recent years, most people don't know the delicacy of Espresso. They just come here to see the atmosphere of Espresso. Must, this is also a kind of Espresso life!

Espresso is a kind of mixed coffee

Espresso is a blend of coffee art that allows people to study its recipe all their lives. Due to the role of high water, it is easy to highlight the characteristics of a single coffee bean, and produce a taste imbalance of Espresso. As a result, coffee companies are really developing their own recipes, even proud of them.

Generally speaking, Japanese coffee beans have a mellow taste, while water-washed beans have a sweet taste; & # 39-year-old beans have a sour taste and taste, while old beans are heavy and thick. As for the recipe, if you write a sound concerto, you can only rely on the long-term experience and self-criticism of the old master, and the strange coffee maker enjoys a high status in Italy.

Espresso is a baking method.

Espresso is a roasting method, and you can find a packet of "Espresso" in the store, which refers to the re-roasted coffee beans, which are boiled into black coffee. The importance of fat has been appreciated in the past, and emulsified fat is the main source of alcohol flavor, so Espresso often uses deep baking to remove fat to the outlet of the pores without spilling a large amount of coffee beans. At this time, the roasting temperature has exceeded Celsius; the whole bean may be spoiled in a matter of 00 degrees Celsius. Therefore, there is no doubt that the mastery of baking degree is an art.

Espresso is a kind of cooking.

Because the flavor of Espresso is so thick, adding milk or other ingredients will not be dilute, so various additives can be made into all kinds of coffee, which has become a kind of cuisine. For example, Espresso can be added to milk to make Cappuccino or caffe Latte; chocolate chocolate can be added to make coffee mocha (caffe Mocha); if only milk foam is added, it will be Espresso Macchiato; in addition, whipped cream can be added to make Espresso ConPanna.
