The varieties of coffee beans introduce how many countries have planted coffee trees

In addition to the classification according to the planting area, there is another classification of coffee plants, that is, coffee trees, or coffee varieties. According to plant classification, the number of varieties of coffee trees is very large, but there are only two main varieties commonly used for coffee; one is "Arabian coffee" and the other is "Robaster coffee". The former tastes pure and tastes good, but the concentration is low and the sour and bitter tastes 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 of the bitter taste of the latter, it is usually acceptable to only a small number of people who particularly like bitter coffee. Most people can't accept it. So Italians usually use these two different kinds of coffee to make a unique Italian espresso.

Due to the spread of coffee in different areas, the age of development is also different, ethnic groups or including religious beliefs are also different, so different regions retain different methods of making and drinking coffee. The earliest is "Turkish coffee"; then there is filtered coffee, Italian espresso (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 are no insurmountable obstacles, but like cooking soybean powder in a mocha pot, it is a kind of creation; but it may not be accepted. I'm talking about being accepted by the public. A certain kind of coffee is accumulated, tried and developed by a certain region or nation for many years, and it is the development and spread of a kind of culture. Although it can continue to develop, it can never be changed at will. This is like making Yu-Shiang Shredded Pork with watermelon peel, which can only be regarded as the invention of a small number of people.

The last concept of coffee classification is the so-called "fancy coffee". This is a coffee drink made from coffee (filtered coffee or Italian espresso) with different ingredients. For example, the most common coffee milk, Cappuccino,Caffe Latte, Irish coffee, royal coffee, and so on. This kind of coffee is a coffee-containing drink 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 the coffee to meet different taste needs. In addition to some of the standards have been formed around the world, with certain production methods, there are some do not have standard production methods. And anyone can create their own unique coffee drinks according to their own hobbies or understanding. The only question is whether the coffee drink you create can be accepted by the public, unless you make it entirely for yourself.
