In addition to the classification of coffee tree plants by planting area, there is another classification, namely coffee tree or coffee variety. According to plant classification, there are many varieties of coffee trees; But there are only two kinds of coffee usually used; One is "Arabic coffee" and the other is "Robas specialty coffee". The former tastes pure and delicious, but its concentration is low, and its acidity and bitterness are less. So the former is usually used to make filtered coffee. But for those who like espresso and bitter coffee, the latter is more popular. Because the latter is bitter, usually only a few people who especially like bitter coffee can accept it. Most people can't accept it. So Italians usually use these two different coffees to make a unique espresso.
Because coffee spreads in different regions, develops in different times and is influenced by different nationalities or religious beliefs, different regions maintain different coffee making and drinking methods. The earliest should be "Turkish coffee"; Then filtered coffee, espresso and so on. This classification concept mainly refers to the selection, processing, grinding and production of different coffee beans. Each has different methods and habits. Although it can be said that no matter which tool you use to make any kind of coffee, there is no insurmountable obstacle, which is like cooking bean powder in a mocha pot, which is a kind of creation; But not necessarily accepted. I mean to be accepted by the public. A certain kind of coffee is the experience, attempt and development accumulated by a certain region or nation for many years, and it is the development and spread of a culture. Although it can be continuously developed, it must not be changed at will. This is like using watermelon skin to make fish-flavored shredded pork, which can only be regarded as the invention of a few people.
The last concept of coffee classification is the so-called "fancy coffee". This is a kind of beverage containing coffee, which is made of different ingredients of coffee (filtered coffee or espresso). For example, the most common milk coffee, cappuccino, latte, Irish coffee, royal coffee and so on. This kind of coffee is a kind of coffee-containing beverage invented by people in various regions for their own taste or to meet the needs of customers. The purpose is to add different ingredients to coffee to meet different taste needs. In addition to the fact that some parts of the world have formed standards and certain production methods, there are some non-standard production methods. And anyone can make their own unique coffee-containing beverage according to their own hobbies or understanding. The only question is whether the coffee drink you created can be accepted by the public; Unless you do it entirely for yourself.
