For a single coffee bean, many factors determine its final flavor, including the coffee tree variety, the coffee bean processing method, and other crucial elements that shape its unique taste profile.

In recent years, with the continuous popularization of specialty coffee, new professions such as roasters and cuppers have emerged as popular careers in the industry. Coffee roasting has also become the preferred method for some baristas and enthusiasts to start their own businesses. For a single coffee bean, there are many factors that determine its flavor: the variety of the coffee tree, the processing method of the coffee beans, the growing conditions of the region where the tree is located, and even whether the tree has shade trees and what type of shade trees they are, among many other influencing factors that are difficult to determine precisely. However, the author believes that each different influencing factor still has its own characteristics.

Coffee Bean Processing Methods

Coffee bean processing methods are divided into the following types: Natural; Semi-Natural or Pulped-Natural; Honey processing; and Washed. The most common processing method we encounter is the washed process. The washed process involves, after harvesting coffee cherries, using special methods to screen out unripe and moldy beans, then removing the fruit skin and placing them in large water tanks for soaking and fermentation. The pectin on the fermented coffee beans naturally falls off, after which they are dried and the outer shell is removed. Countries that primarily use the washed process are mainly Central and South American countries as well as African countries. Washed beans are characterized by a relatively clean flavor profile and clear taste, but comparatively lower sweetness.

Natural Processing Method

The natural processing method (Natural/Dry processing) involves manually selecting harvested coffee cherries first, then placing the entire cherries in ventilated, dry sunlight for exposure, after which the fruit skin, pulp, and outer shell are removed.

Countries that primarily use the natural processing method include some African countries and Brazil. The natural processing method is greatly influenced by the processing environment and craftsmanship level, so quality varies considerably. However, overall, naturally processed coffee beans have higher sweetness and possess unique fermentation flavors. However, when fermentation flavors are not properly developed, they can transform into unpleasant odors, fermented bean paste flavors, musty flavors, and so on.

Semi-Natural Processing Method

Semi-natural processing, also known as semi-washed or pulped-natural processing, involves first removing the fruit skin of coffee cherries in the same way as the washed process, then placing the pectin-coated coffee beans in ventilated, dry sunlight for exposure, after which the hulling process is performed. Countries that primarily use the semi-natural method for processing coffee beans are mainly Brazil, where semi-natural processing is a unique processing method. Semi-naturally processed coffee beans are less likely to incorporate off-flavors compared to natural processing, while maintaining some clean mouthfeel and simultaneously carrying a small amount of fermented flavors similar to dried fruits.

Honey Processing Method

Honey processing is very similar to the semi-natural processing method, but differs in that honey processing retains more pulp components during sun exposure. Countries that primarily use the honey processing method for coffee beans are mainly Costa Rica. Since honey processing requires a higher level of craftsmanship, honey-processed coffee beans combine clean mouthfeel with higher sweetness, while appropriately retaining fruit fermentation flavors.
