Usually the region where coffee beans are suitable for growth is in the countries between the Tropic of Cancer, called "Coffee Zone", Central and South America, Arabia, East Africa, southern Asia, Oceania and so on are all in this region, and the better coffee can be produced in countries with alpine topography, because coffee is suitable for growing on slopes with an altitude of about 1000Mak 2000m above sea level, which requires sufficient rainfall, but not too wet. It is best to have mild sunshine during the day, clouds in the evening, and a temperature of about 10 degrees Celsius but not too low at night.

Planting and treatment of Arabica Coffee Bean

In addition to the origin, the method of planting coffee beans (shade planting, organic cultivation, fertilization) and the process of picking coffee beans (whether the working conditions of farm workers enable them to have good working quality) also affect the taste of coffee. A good coffee tree may also produce bad beans.

The process of post-harvest treatment of coffee beans is also very important. There are three kinds of post-processing methods, such as sun exposure, water washing and honey treatment. Sun-dried coffee beans have rich fruit aromas, sweet aftertaste and high mellowness. Washed coffee beans have fruity or floral aromas, moderate acidity and low mellowness. Honey-treated coffee beans have a sweeter aftertaste, delicate fruit aromas and high mellowness.

At present, there are various grading methods in the world according to the size of coffee beans, the quality of post-processing, and planting elevation, which can also be used to judge the quality of coffee beans. In addition, some coffee packaging will have Fairtrade, sustainable management, organic cultivation, high altitude and other certification labels, most of the coffee beans with these labels are not poor. Although some proofs may not be directly related to quality, they indicate that the coffee beans have been carefully processed.

3. Preservation of raw coffee beans

Raw coffee beans are very stable before they are roasted and can be preserved for a year under good conditions. But if you put it in a place with high humidity, it may produce bacteria, and coffee beans will also be contaminated with the bad smell in the air.

It is worth mentioning that the so-called old beans (aged) refers to the coffee beans stored in the low humidity and high altitude environment of the country of origin, which are turned and kept fresh regularly to cultivate a particularly mellow taste. This kind of coffee bean tastes good, but it is also expensive. The coffee beans stored in the general warehouse are not old beans, so don't be deceived.

Taiwan coffee producing area

Taiwan is on the 23.5 degree Tropic of Cancer, which is suitable for growing coffee. At present, people are more familiar with producing areas such as Yunlin Gukeng, Nantou Huisun, Tainan Dongshan, Hualien Ruisui, and so on. The climate and soil in these areas are conducive to the cultivation of coffee trees, mostly Arabica coffee beans with slightly nutty aromas, mellow coffee and low bitterness. In addition, in recent years, small farmers have also grown their own coffee in Sanjimen, Pingtung and Shimen, Taipei, mostly Arabica coffee beans. although the scope of cultivation is not large, the coffee produced has a different style.

Although Taiwan's geographical location is in the latitude zone suitable for growing coffee, the labor cost of Taiwan is higher than that of coffee producing areas such as Africa, Central and South America or Indonesia. Due to cost considerations, the development of coffee in Taiwan is more likely to be restricted.
