The reason why coffee beans can't be roasted if they are not roasted thoroughly

Reasons why coffee beans are not roasted thoroughly

Coffee beans are an important raw material for making coffee, and roasting is the process of heating the raw beans to change their taste and aroma. However, sometimes we may encounter coffee beans that are not roasted thoroughly. So, why does this happen? This article will explore this issue from several aspects.

1. Insufficient baking time

First of all, a common reason for under-roasting of coffee beans is insufficient roasting time. During the roasting process of coffee beans, the temperature and time need to be controlled to achieve the desired effect. If the time is not long enough or the temperature is not high enough, the potential flavor and aroma inside the coffee beans cannot be fully developed.

Of course, in addition to controlling time and temperature, other factors need to be considered, such as moisture content, altitude, etc., which have a certain impact on specific varieties.

2. The ambient humidity is too high

Another reason for undercooking is too much humidity. Coffee beans release moisture during the roasting process. If the humidity is too high, the moisture cannot evaporate fully. As a result, the moisture content inside the coffee beans will be high, resulting in undercooking.

Therefore, when roasting coffee beans, you need to pay attention to controlling the ambient humidity and maintaining proper ventilation and drying conditions.

3. Coffee bean quality issues

In addition to the above two reasons, undercooked coffee beans may also be related to their own quality. If there are some problems with the coffee beans themselves, such as uneven size, damage or aging, it is difficult to achieve the ideal effect when roasting.

Therefore, when choosing to buy coffee beans, you should pay attention to purchasing high-quality varieties and store them correctly to avoid adverse effects on them.

4. Ruby Craftsmanship

The Ruby Process is a new type of low-temperature, long-term slow heating technology that can retain more nutrients and flavor while avoiding the problem of undercooking.

This process controls the heating time and temperature, allowing the coffee beans to better bring out their flavor and aroma while keeping the internal moisture evaporated. Therefore, when roasting coffee beans, you can consider using the ruby ​​process to solve the problem of undercooking.

in conclusion

In summary, there are many reasons why coffee beans are not roasted thoroughly. These include insufficient roasting time, excessive humidity, and coffee bean quality problems. In order to solve this problem, we need to pay attention to controlling the temperature and time, and maintain a dry and ventilated environment. In addition, when choosing to buy coffee beans, we must choose high-quality varieties and store them correctly to avoid adverse effects.

Finally, the ruby ​​process is a new technology that can effectively solve the problem of undercooking and can also retain more nutrients and flavors. Therefore, when processing coffee beans, you can consider using this process to improve the quality of coffee.
