In the world of coffee, roasting is an ancient and fascinating art.

1. Definition and classification of coffee roasting degree

The degree of coffee roasting refers to the different colors, tastes and flavors of coffee beans due to the control of temperature and time during the roasting process. We can divide the degree of coffee roasting into three main categories: light-medium roasting, medium roasting and deep roasting.

Light-medium roast : The surface of the coffee beans is light yellow to light brown, with a small amount of oil on the surface and a lower bean temperature. Coffee beans with this roasting degree have a fresh taste, bright acidity, and rich fruity and floral aromas. It is suitable for coffee lovers who pursue the original flavor and like a refreshing taste.

Medium roasted : The coffee beans are dark brown with obvious oiliness and moderate bean temperature. Medium roasted coffee beans have both sourness and sweetness, and a strong sense of balance. They are suitable for making various daily drinks and are also the first choice in many competitions and tasting sessions.

Deep roasting : The coffee beans are dark black with a very noticeable oily sheen. The bean temperature is relatively high. Deep roasted coffee beans have a rich taste, strong bitterness, and a unique caramel and chocolate flavor. They are suitable for people who like strong-flavored coffee.

2. The impact of roasting degree on coffee

Different roasting degrees not only affect the taste of coffee, but also directly affect the appearance, aroma and nutritional value of coffee beans. Lightly roasted coffee beans retain more vitamins and antioxidants, while deep roasting will destroy some substances due to high temperature. As the roasting degree deepens, the acidity of the coffee beans gradually weakens and the bitterness increases, which makes coffee beans of different roasting degrees have completely different effects when paired with beverages.

3. Selection and application of coffee roasting degree

For ordinary consumers, choosing coffee beans that suit their taste often becomes a kind of enjoyment. If you like a fresh taste, you can choose light or medium roasted coffee beans; if you pursue a sense of balance, medium roasting is a good choice; if you like strong flavors, deep roasting can meet your needs. Different roasting degrees are also suitable for making different beverages. For example, light or medium roasted beans are suitable for making simple extraction coffee such as hand brewing and drip filtering, while deep roasted beans are more suitable for making strong-flavored coffee such as espresso or French press.

In a coffee shop or cafe, the choice of roasting degree reflects the characteristics and philosophy of the store. Some shops focus on medium roasting, pursuing balance and quality; others adjust the roasting degree according to factors such as season and origin to bring different experiences to customers.

4. Future Development of Coffee Roasting Degree

With the continuous advancement of science and technology and consumers' in-depth understanding of coffee culture, coffee roasting technology is also constantly developing and innovating. We may see more types of roasting degrees appear, bringing more choices and surprises to coffee lovers. With people's pursuit of health and quality, how to scientifically and reasonably control the roasting degree so that it can meet the taste requirements and retain the nutritional value of coffee beans will become an important direction for future research.
