Detailed explanation of the whole process of roasting coffee beans and making coffee

Roasting coffee beans is one of the important steps in making coffee, which can give coffee beans a special aroma and taste. The following will introduce the whole process of roasting coffee beans to make coffee in detail.

First of all, it is very important to choose the right coffee beans. Coffee beans produced in different regions have different flavor characteristics. For example, Brazil's Brazilian red fruit has a strong and sweet chocolate flavor, while Ethiopia's Yirgacheffe has a floral and citrus flavor. When choosing, you can choose according to your personal taste preferences.

Next is the roasting process. Roasting is divided into three stages: light, medium and deep. In the light stage, due to the low temperature, the water inside the coffee beans begins to evaporate and some acidic substances are released, making the coffee obtained in this stage bright and refreshing with prominent acidity. In the medium stage, the internal water is further lost and bubbles are formed. At this time, the coffee beans begin to undergo chemical reactions and the taste will be more balanced. The deep stage is the final stage of roasting, when the surface of the coffee beans begins to become shiny and produce bitterness and caramel aroma.

The last step is grinding and brewing. Before grinding the coffee beans into powder, you need to choose the appropriate coarseness according to the brewing method. Generally speaking, if you use a drip or French press, you need a finer powder; if you use an espresso machine, you need coarser particles. Pour the right amount of coffee powder into the filter, soak and extract it with the right amount of warm water to get a delicious cup of coffee.
