The origin is not sour, the mystery of acidity in quality selection of coffee beans?

The acidity of coffee beans has always been one of the important indicators that coffee lovers pay attention to. Acidity not only affects the taste of coffee, but also reflects the origin and quality of coffee beans. So, why do coffee beans from different origins have different acidity?

First of all, we need to understand that acidity does not refer to the "sour" taste, but describes the degree of irritation and freshness caused by a certain substance on the tip of the tongue (such as fruit, citrus, etc.). Therefore, when talking about the acidity of coffee beans, it is not discussing whether it has a clearly identifiable "sour" taste like lemon juice or apple juice.

Secondly, there are two main aspects that affect the acidity of coffee beans: soil and climate conditions and processing methods.

The first is soil and climate conditions. These factors determine the content of various chemicals in the growing environment within the cultivation area, as well as the sunshine hours, temperature and humidity. For example, high altitude areas usually have lower temperatures and humidity, which is conducive to the slow maturation of coffee beans, resulting in higher acidity. In contrast, the climate conditions in low altitude areas are hotter and more humid, causing coffee beans to mature faster and have relatively lower acidity.

The second is the processing method. Coffee beans from different origins will go through different processing methods after being picked. For example, the "washed method" removes the pulp and soaks the coffee beans in water for fermentation and cleaning; while the "dry method" is to dry the whole fruit and then peel off the coffee beans. These processing methods will affect the internal chemical content and flavor characteristics, and then affect the acidity.

In summary, when choosing coffee that suits your taste, you need to consider the origin and quality factors, and understand the impact of different origins and different processing methods on acidity. Everyone has their own preferences for acidity, and you can choose according to your favorite taste when choosing.

Therefore, "select based on origin and quality". While enjoying coffee, we should also pay attention to understanding the mystery of the acidity of coffee beans to better meet our own taste needs.
