From raw beans to cooked beans, factors such as temperature, time, and rhythm in the roasting process directly affect the taste and aroma of coffee. Deeply roasted coffee beans can produce a rich taste and deep aroma, while lightly roasted beans can retain the sourness and sweetness and fresh aroma of the coffee beans themselves. Through in-depth exploration, we can better understand the impact of roasting on coffee quality in order to make more delicious coffee.

In the world of coffee, the roasting stage is an extremely important yet mysterious link. It is like a carefully choreographed movement that affects the flavor, aroma and taste of coffee. But what exactly is the coffee roasting stage? How does it affect the coffee we finally taste?

1. Definition of coffee roasting stages

The coffee roasting stage refers to the different time periods and corresponding changes of coffee beans during the roasting process. From green beans to cooked beans, each roasting stage has unique characteristics and indicators. Accurately mastering these stages is the key for roasters to pursue high-quality coffee.

2. Baking stage segmentation

1. Light roasting : At this stage, the color of the coffee beans gradually changes from the original dark green to light yellow, and a small amount of oil appears on the surface. At this time, most of the moisture inside the coffee beans has not completely evaporated, presenting a bright and fresh taste, which is suitable for those coffee lovers who like obvious sour taste.

2. Medium roasting : As the temperature rises, the color of the coffee beans deepens further, turning into dark yellow or light brown. At this time, the moisture inside the coffee beans evaporates further, and the aroma begins to emanate, showing a balanced acidity and bitterness. This is the common degree of coffee roasting in daily life.

3. Deep roasting : At this stage, the color of the coffee beans turns dark brown, the surface is obviously oily, and it presents a rich caramel and chocolate aroma. Due to the evaporation of a large amount of water, the taste of the coffee becomes richer and mellower, which is suitable for people who like strong-flavored coffee.

3. The impact of roasting stage on coffee

1. Flavor changes : Different roasting stages will cause significant changes in the flavor of coffee, from the initial sweet and sour taste to the balanced taste in the middle and then to the rich taste in the late stage. These changes directly affect the taste experience of coffee.

2. Aroma release : The temperature and time during the roasting process determine the type and intensity of the aroma. Moderate roasting can bring rich aroma, while over-roasting may cause the aroma to disappear and the coffee to lose its original charm.

3. Irritation degree : The roasting stage also affects the degree of irritation of coffee to the stomach and intestines. Lightly roasted coffee has a distinct sour taste and is less irritating to the stomach and intestines; while deeply roasted coffee has a lower caffeine content and a rich taste, which is more irritating to the stomach and intestines.

4. Challenges and Pursuits of Bakers

Every roaster is constantly researching and exploring the changes in different coffee beans during the roasting process in order to find the most suitable roasting stage. This requires not only rich experience, but also awe for each coffee bean and passion for coffee culture.
