1, the choice of raw coffee beans is very important.
The choice of raw beans directly determines the taste of the final coffee. Without good quality raw beans, it is impossible to drink good coffee. Mixing different coffee beans in different proportions may form a better taste than the original beans, but if you want to drink more pure taste, you should pay attention to the choice of the original beans.
2, coffee cleaning and drying
Peel the coffee beans from the coffee cherries, then soak them in water, and then put them on the spacious terrace to dry, or dry them with modern equipment.
3. Coffee baking
Coffee beans should be roasted in a roaster (a large rotating barrel). After 5-7 minutes of high temperature, fully dry the residual moisture in the coffee. At this time, the color of coffee will change, turn yellow slowly, and you can smell the rich fragrance of coffee.
After a few minutes, you can hear the crack of coffee. At this time, the volume of coffee beans will double, and with the popping sound (similar to popcorn sound), the color of coffee will turn dark brown. However, it should be noted that the coffee is not roasted well at this time, and it still has a strong sour taste, which needs constant roasting.
4, the release of coffee taste
After roasting in the roaster for about 15 minutes, the taste of coffee will be completely released (but it depends on different kinds of coffee), which also means the end of the coffee roasting process.
