Abstract: Coffee roasting goes through eight stages, each of which produces different flavors and tastes. From raw beans to deep roasting, roasters need to master the appropriate temperature and time to explore the mysteries of coffee in order to present the best coffee flavor. This process requires roasters to have rich experience and skills to create a unique coffee taste.

In the world of coffee, roasting is a magical process that transforms an ordinary coffee bean into a fragrant drink. The degree of coffee roasting is the key to the formation of coffee flavor. This article will explore the eight levels of coffee roasting in detail and take you into the mysterious world of coffee flavor.

1. Light Roast

The surface of lightly roasted coffee beans is light brown with a thin layer of oil on it. Coffee at this roasting level has a bright taste, obvious acidity, and fruity and floral aromas. Due to the short roasting time and relatively high caffeine content, it tastes more stimulating. Lightly roasted coffee can also show a unique sense of freshness that can lift people's spirits.

2. Light Baking

The color of slightly lighter roasted coffee beans is darker, but some light traces can still be seen. Coffee at this roasting level has a mellow taste, with a slight sweetness and balanced acidity, and tastes smooth and refreshing. Slightly lighter roasted coffee has a unique flavor, with the vitality of fresh coffee beans and some subtle changes brought about by roasting.

3. Medium Roast

Medium roasted coffee beans are dark brown with a more noticeable oily surface. Coffee at this roasting level has a rich and balanced taste, with a perfect balance of sweetness and acidity. Medium roasting allows the characteristics of the coffee beans to be fully reflected while maintaining a certain freshness. It is the first choice of many coffee lovers.

4. Medium Baking

Medium roasted coffee beans are darker in color, with a more even sheen. Coffee at this roasting level has both a rich flavor and a certain softness. Medium roasted coffee beans begin to show a unique roasted aroma, allowing people to feel the wonderful changes brought about by roasting while tasting it.

5. Deep Baking

Deep roasted coffee beans are dark black with a very noticeable oily surface. Coffee at this roasting level has a strong and rich taste, with obvious sweetness and very low acidity. Deep roasting maximizes the characteristics of the coffee beans and also allows the coffee to caramelize, bringing a unique caramel aroma and taste. Deep roasted coffee is suitable for those who like strong flavors.

Six to eight levels (omitted)

Due to space limitations, this article will not go into detail about the last two levels. The roasting degree from six to eight levels gradually tends to the extreme, and each level has its own unique flavor and characteristics. For example, the roasting degree of six and a half to seven points makes the coffee beans show a unique chocolate aroma and taste; roasting above eight points makes the coffee beans almost lose their original characteristics, presenting a uniform burnt bitter taste and rich coffee aroma. These levels of flavor changes need to be explored and experienced in actual tasting.

The degree of coffee roasting is an art. Each level contains infinite mysteries and flavor changes. From light to deep, the transition of each stage is accompanied by the transformation and sublimation of flavor. Exploring the eight levels of coffee roasting is like entering a world full of surprises and discoveries. In this process, we can not only taste the wonderful flavor of coffee, but also feel the infinite possibilities of life.
