Coffee beans: a journey of tasting roasted aroma

Coffee Beans Roasting Tour

Coffee is one of the most popular drinks in the world, and coffee beans are the key to making delicious coffee. Coffee beans produced in different regions have unique flavors and characteristics, and these flavors will be further enhanced after careful roasting. This article will take you on a journey of tasting roasting and explore the mellow aroma hidden behind coffee beans.

1. Origin and flavor

Each country and region has its own unique soil, climate, altitude and other factors, which directly affect the coffee beans grown there. For example, Arabica coffee beans from South American countries such as Brazil and Colombia usually have a soft and fragrant aroma; while Kenya AA coffee beans grown on the high-altitude mountains of Kenya, Africa, have a distinct and rich fruity acidity.

2. Coffee Bean Processing

After being picked, coffee beans go through a series of processing steps to remove the pulp and outer skin and expose the seeds inside. These seeds are what we know as coffee beans. Common processing methods include dry and wet methods.

The dry method is one of the oldest and most traditional processing methods, also known as natural processing. In this process, the picked coffee cherries are dried in the sun until they are completely dry. The wet method is to soak the coffee cherries in water for fermentation, washing and depulping.

3. Baking and flavor development

Roasting is the key step to make coffee beans show the best flavor characteristics. By controlling factors such as time, temperature and fire, coffee beans can be roasted to different degrees.

Light roasting is usually used to highlight the unique flavor of the origin, retaining a higher moisture content and more organic acid components. Medium roasting is the choice to balance the taste and flavor while retaining a certain acidity and sweetness. Deep roasting will produce oil on the surface of the coffee beans, bringing a rich caramel and chocolate flavor.

4. Coffee tasting and evaluation

Coffee tasting is an art and a skill. Professional baristas judge the quality and flavor characteristics of coffee beans through steps such as smelling, tasting and evaluating.

During the tasting process, we can smell the aroma of coffee and identify whether there are aromas of fruit, nuts or chocolate. Next, swirl the liquid in the mouth on the tongue to distribute it so as to fully experience its taste characteristics. Finally, pay attention to whether there is obvious acidity, bitterness or sweetness when sliding it across the tongue.

5. Storage and preservation

To ensure that the coffee beans last longer and retain their fresh taste, it is important to store them correctly.

First, you should choose vacuum-packed coffee beans before buying to ensure that they will not be affected by factors such as oxygen, humidity and light during transportation and storage. Secondly, store the coffee beans in a dry, cool place away from direct sunlight. Finally, try to keep the packaging intact before use and use it quickly after opening.
