In the world of coffee, roasting is an ancient and fascinating art. Different degrees of roasting are like different magics cast on coffee beans, giving them different flavors and characteristics. Let’s discuss the eight degrees of coffee roasting in detail and understand the transformation of coffee beans during the roasting process.

Light roast

The surface of lightly roasted coffee beans is light brown, and the beans remain hard and have a shiny surface. Coffee at this roasting level has bright acidity and fresh fruity aroma, and a refreshing taste. It is a favorite flavor of many coffee lovers.

Micro-medium baking

Lightly roasted coffee beans begin to show a distinct brown hue. At this point, the beans are slightly fragile, the fruit acidity gradually fades, and a moderate sweetness and a slight nutty aroma begin to appear. Coffee at this roasting level has a strong sense of balance and is suitable for daily drinking.

Medium Roast

The color of medium-roasted coffee beans deepens further, showing a rich coffee aroma. At this time, the oily sheen begins to appear on the surface of the beans, and the fruit acidity in the taste has basically disappeared, replaced by a rich sweetness and nutty aroma. It is suitable for making hand-brewed and drip coffee.

Medium dark roast

Medium-dark roasted coffee beans are darker in color, have a noticeable oily surface, and have a richer caramel flavor. At this point, the taste begins to become rich and balanced, with both sweetness and bitterness coexisting, making it suitable for making espresso and Italian coffee.

Dark roast

Deeply roasted coffee beans are very dark in color, almost black, and have a very noticeable oily surface. Coffee beans at this roasting level have a strong caramel flavor, a significantly enhanced bitterness, and very low acidity. Deeply roasted coffee has a unique flavor and is suitable for people who like strong flavors.

Slightly dark roast

Slightly dark roasted coffee beans are slightly different from dark roasted ones. Although the color is also dark, the caramel flavor is not as obvious as dark roasted ones. The bitterness is moderate in the taste, but it still retains a certain acidity, presenting a subtle sense of balance. This degree of roasting has a rich flavor and is suitable for coffee lovers who pursue a multi-layered taste.

French dark roast (also called "Italian roast")

This is a degree of coffee roasting that is close to the extreme roasting. The surface of the coffee beans is dark black with a strong oily sheen. The taste is extremely rich and bitter. The fruit acid almost disappears. Due to the large amount of water evaporation, the coffee beans become very crisp. Coffee roasted in this way is often used to make heavy-flavored coffee drinks such as espresso. It is loved by some people for its unique rich flavor and strong aroma. ​ ​ ✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔✔ ​​ ✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️✔️ ​​

However, it should be noted that over-roasting may cause the loss of more nutrients in coffee beans and the taste to be too monotonous. Therefore, in actual operation, it is necessary to master the temperature and time to show the best taste and flavor. At the same time, we should also pay attention to avoid excessive pursuit of heavy taste and ignore other important factors such as freshness and quality. In daily life, it is equally important to choose coffee beans that suit your taste and the right roasting method. Different tastes and preferences reflect people's diverse experience and understanding of life. Whether it is light roasting or dark roasting, it has its unique beauty. The important thing is that we can enjoy the process and get pleasure and satisfaction from it. ​
