Whether it's the afterglow of sunset or dusk, I always hope to have a sip of fragrant coffee in the wind. I don't know how warm that feeling is. ...

Speaking of coffee, everyone must be afraid of the glass fog caused by the dazzling array of coffee on the market. Brown's coffee comes out first. Blue Mountain, Mantening. Then cappuccino and latte. What is this?

In fact, the world of coffee is mainly divided into two types, one is single-product coffee like Blue Mountain and Mantening, which is mostly divided by regions. The other is espresso based on espresso.

Single product coffee is usually named after coffee beans produced in a single producing area. For example, Blue Mountain Coffee is located in the Blue Mountain Range of Jamaica. Its caffeine content is very low, less than half that of coffee in other places. The unique flavor of "Blue Mountain Coffee" is related to the unique geographical location and climatic conditions in the Blue Mountain area of Jamaica.

The Blue Mountains in Jamaica have fertile new volcanic soil, fresh air and almost no pollution. It is rainy all year round, and the temperature difference between day and night is large. Because of the special geographical environment here, every afternoon, the top of the Blue Mountain is covered with clouds, which not only blocks the sunshine for the coffee trees, but also brings abundant water vapor. It is this geographical basis that the taste and fragrance of Blue Mountain Coffee is unique to coffee produced all over the world. Not all coffee produced in the whole blue mountain area can be called blue mountain coffee, but only coffee grown in the blue mountain area above the altitude of 1800 meters can be called "blue mountain coffee".

Coffee beans produced in low-altitude blue mountains can only be named "Jamaica Alpine Coffee" because of the difference in quality, but not "Jamaica Blue Mountain Coffee". Because the climate, soil and air in the blue mountain area are suitable, the seedlings of the same blue mountain variety are transplanted to places with similar climate, such as Hawaii, Kenya and Papua New Guinea, and the quality of the output can not be compared with the real "blue mountain coffee".

Italian coffee is called Italian coffee because espresso, a method of making coffee quickly, was invented by Italians. In Italy, espresso is just like our bubble tea, even more like a necessity, because they may drink several cups a day, which can improve work efficiency, but when we are making bubble tea, we will die of obesity if we drink one cup a day. Coffee used in espresso is usually a mixture of two or more kinds of coffee beans, mainly because Italians think that a single coffee bean can't have a balanced taste (on the one hand, because of the brewing method), so they usually use more than three kinds of coffee beans to prepare a balanced espresso formula. At present, most espresso coffee on the market uses integrated beans.

Espresso is based on espresso, and espresso uses an espresso machine. ""At 8~9 atmospheres, coffee with a temperature of about 85~95 degrees Celsius and 7 grams of coffee powder is brewed in about 30 seconds, and the amount of powder is controversial. Some people think that 7 grams will be over-extracted, so it is suggested to use 14. Anyway, espresso is only about 30cc of coffee, which is extremely rich. A good cup of espresso can last for dozens of minutes (of course, coffee brewed in mocha pot can also be called espresso, and espresso machine is not limited). After adding more than 100 cc of milk foam to the cooked espresso, about 150cc of coffee is made from milk, which is the famous cappuccino.

When espresso was introduced to the United States, in order to satisfy the psychology of American big brother, the drink was bigger, so more milk was added and it became a "latte" all over the street. In Italy, the word latte means milk. If hot water is added to espresso, it will become the American coffee in everyone's mouth. However, except for coffee players, it is not enough for Americans to drink only a small cup of 30cc coffee, so their lattes are very big, and even cappuccino has become bigger, which has led Italians to call out the name of cappuccino recently. Cappuccino specification issued by Italian National Espresso Association: It is determined that the size of a cup of cappuccino should be only 150ml, where 120. The composition of milk should be at least 3.2% protein and 3.5% fat, and the milk steam should be heated to 55 degrees Celsius.

In addition, the knowledge of espresso can be deep. The thickness of coffee powder alone can waste dozens to hundreds of grams of coffee beans and valuable business time. No matter whether the thickness of coffee powder is good or not, the strong coffee flavor can make you wander between heaven and hell. What's more, there are powder quantity, brewing temperature, brewing pressure, charging channel and charging method, and so on. There are many things to learn and study. Maybe this is the fun of coffee!
