Coffee bean roasting degree types: understand different degrees of roasting and taste the diverse flavors of coffee

Coffee bean roasting types and flavors

The roasting degree of coffee refers to the degree to which coffee beans are heated at different temperatures. Different degrees of roasting will give coffee beans different flavor characteristics. Below we will introduce several common roasting degrees of coffee beans and their corresponding flavors.

Light roast

Light roasting means that the coffee beans are slightly heated at a lower temperature, so that the surface of the beans changes color slightly, but the inside still maintains a high moisture content. This roasting method retains most of the original flavor, so light roasted coffee usually has a bright and refreshing taste, with obvious acidity and floral and fruity aroma.

Medium/City/American Coking

Medium or City is a roast between Light and Medium Dark/Full City. At this stage, some surface oils have begun to appear and the color is darker. The beans are usually well balanced in acidity and sweetness while retaining some of the original flavor. This is the roast level that many people prefer and is suitable for brewing Americano.

Zhongshen/Chengdu Coking

Medium-dark or Full City is a roast between medium and dark. At this stage, the oil on the surface of the coffee beans is more obvious and the color is darker. The coffee beans processed in this way usually have a rich and full taste, with a certain degree of bitterness and caramel aroma.

Dark roast/French roast

Dark roast or French grade is the result of high temperature and long-term heating of coffee beans. At this stage, the oil on the surface of the coffee beans is fully released and the color becomes very dark and shiny. Due to the high temperature treatment, a large amount of internal water loss and complete oxidation of sugar substances, dark roasted coffee usually has a strong and bitter taste with a roasted and chocolate aroma.

Special baking method

In addition to the above common roasting degrees, there are also some special roasting methods. For example, the Italian level is the result of heating the coffee beans at extremely high temperatures, causing oil to drip from the surface of the coffee beans and the color to be very dark. The coffee processed in this way usually has a very strong and bitter taste and a distinct carbonized taste.

In summary, different degrees of coffee bean roasting will produce a variety of different flavor characteristics. Choosing a roasting degree that suits your taste preferences allows us to enjoy a more diverse and rich coffee flavor.
