Coffee bean production time revealed: the secret of perfect roasting

Coffee Bean Roasting Process

Roasting coffee beans is one of the key steps to making delicious coffee. Proper roasting can release rich aroma and taste of coffee beans, thus improving the quality of coffee. So, what is the secret behind perfect roasting? Below we will reveal the secret of coffee bean production time.

Green coffee processing

Before roasting, the green beans need to be processed. This process includes removing impurities, screening size and grading. Only high-quality green beans that have been carefully selected and processed can produce high-quality coffee.

Warm-up phase

Before you start roasting, you need to preheat the equipment. This stage can help improve work efficiency and ensure temperature stability. Usually, the preheating temperature will vary depending on the type and style of coffee.

Early development stage

Once the equipment is preheated, the formal roasting process can begin. The initial development stage is one of the most critical parts of the entire roasting process. During this stage, the coffee beans will undergo changes such as water evaporation, color change, and aroma release.

The first burst

When the beans reach the right temperature, they will make their first popping sound. This is caused by the rapid expansion of the gas produced by the internal water vaporization. At the same time, the surface of the coffee beans will begin to change color.

Mid-term development stage

As time passes and the temperature rises, the coffee beans enter the mid-development stage, where they continue to release aroma and gradually develop a deeper, fuller taste.

The second explosion

When the coffee beans reach the right temperature again, they will undergo a second crack. Similar to the first crack, the internal water evaporates rapidly, producing gas expansion, and the color of the coffee beans surface will further deepen.

Late Development Stage

After the second crack, the coffee beans enter the later development stage. At this time, the roaster needs to control the temperature and time according to the desired taste and flavor. The handling of this stage is very critical, because the slightest mistake can lead to over-roasting or under-roasting.

Cooling and storage

When the coffee beans reach the ideal roasting degree, they need to be cooled and stored. This process can help stabilize the aroma of the coffee beans and reduce the oxidation reaction caused by their contact with the external environment. Usually, the cooling time is about 24 hours.

Conclusion

Through the exploration of the secrets of coffee bean production, we know that there are many mysteries behind perfect roasting. From the processing of green beans to the final cooling and storage, factors such as temperature, time and technology need to be carefully controlled at each stage to achieve the ideal effect. Only carefully roasted coffee beans can produce delicious coffee with rich aroma and taste.
