There are several types of coffee beans, exploring the diversity of coffee

Classification of coffee beans

Coffee is one of the most popular beverages in the world, and coffee beans are the key ingredient in making coffee. Coffee beans can be divided into several different types depending on their origin, growing conditions, and processing methods. In this article, we will explore the diversity of coffee beans and introduce some common classification methods.

1. Origin

First, we can classify coffee beans according to the geographical location they are produced in. There are three main producing areas in the world: Latin America, Africa and Asia.

- Latin America: Latin America includes Brazil, Colombia, Mexico and other countries. It produces many high-quality coffees with strong taste, moderate acidity and nutty or chocolate flavors.

- Africa: African countries such as Ethiopia, Kenya and Tanzania are known for their floral aromas and rich flavors. These regions produce many high-quality and uniquely flavored Arabica coffees.

- Asia: Countries in Asia such as Indonesia, Vietnam and the Philippines produce many coffee beans with low acidity, rich taste and spicy flavor.

2. Coffee tree varieties

In addition to origin, coffee beans can also be classified according to the variety of coffee tree they are grown in. Currently, there are two main varieties: Arabica and Robusta.

- Arabica: Arabica is one of the most common and popular coffee bean varieties. It has a high acidity, floral aroma and smooth taste, suitable for making espresso and hand-poured coffee.

- Robusta: Robusta has a stronger bitter taste and lower acidity. This bean is often used to make espresso or blend to increase its bitter characteristics.

3. Treatment methods

Another important classification method is to divide coffee beans according to the processing method. The processing method can affect the flavor and taste of coffee beans.

- Dry Processing: Dry processing is one of the oldest and most traditional processing methods. In this method, the coffee cherries are dried in the sun until they are completely dry, and then the outer skin is peeled off to obtain the coffee beans. This processing method usually gives the coffee beans a stronger flavor and taste.

- Wet method: The wet method is a more complex and time-consuming process. In the wet method, the coffee cherries are peeled and fermented, and then washed and pulped to obtain clean coffee beans. This processing method usually produces a fresher and brighter flavor.

4. Additional categories

In addition to the above three main classification methods, there are some other factors that can be used to further judge coffee beans:

- Strength: According to the degree of roasting, the strength can be divided into dark roasting, medium roasting and light roasting levels.

- Single origin and blend: Single origin refers to coffee beans produced from the same origin or the same farm, while blend is a mixture of coffee beans from different origins or different varieties.

- Organic vs. Non-Organic: Organic coffee refers to coffee beans grown without chemical pesticides and fertilizers, while non-organic is the opposite.

in conclusion

Through the above classification methods, we can see the diversity of coffee beans. Each classification method will affect the flavor and taste of the final drink. Therefore, when choosing coffee that suits our taste, we can choose specialty coffees made from different origins, varieties and processing methods according to our preferences.
