1. Starbucks coffee prices, origin and types

Green coffee beans mainly come from Asia, Africa, and South America. Green coffee beans produced in different regions have different flavors and aromas. Common origins include Brazil, Colombia, Ethiopia, and other countries.

In addition, according to different types, there are two common categories: Arabica and Robusta. Arabica has a smooth taste with floral and fruity aromas, while Robusta is richer and has a bitter taste.

2. Growth environment and treatment methods

The quality of green coffee beans is closely related to the environment they grow in. Factors such as climate, altitude and soil will affect the taste and aroma of coffee beans.

Generally speaking, coffee beans from high altitude areas have better quality. This is because high altitude areas usually have lower temperatures and a large temperature difference between day and night, which is conducive to the production of complex flavor substances during the ripening process of coffee fruits. In addition, fertile soil with good drainage is also an important factor in ensuring the quality of coffee beans.

In terms of processing methods, green coffee beans need to go through steps such as picking, peeling, fermentation, and drying. These steps play a vital role in the taste and aroma of the final product.

3. Quality Assessment and Classification

To evaluate the quality of green coffee beans, professionals usually conduct cupping tests, in which they evaluate the differences between different samples based on indicators such as aroma, taste, acidity and sweetness.

According to the evaluation system of the International Standards Association (scaA), the quality of coffee beans can be divided into different grades such as special grade, first grade and second grade. Special grade coffee beans usually have a distinct flavor and aroma, while second grade coffee beans are relatively ordinary.

4. Storage and baking

Green coffee beans need to be stored away from direct sunlight and humidity. At the same time, they also need proper ventilation to maintain freshness.

During the roasting process, green coffee beans undergo chemical changes and release a variety of complex flavor substances. Roasting time and temperature are key factors affecting the final taste and aroma.

5. Usage suggestions

Because green coffee beans have a strong and diverse flavor profile, they are often used to make high-end products such as single origin or blended blends. In addition, green coffee beans can also be used on special occasions to showcase their uniqueness.

However, for home use, it is recommended to use roasted coffee beans to make beverages because they still retain a certain amount of impurities and bitter taste during the unprocessed process.

Conclusion

As a special coffee raw material, green coffee beans have their own unique characteristics and qualities. Understanding these characteristics and qualities can help us better choose coffee beans that suit our taste and enjoy the best coffee experience.
