Dark and light roasted coffee beans: taste comparison, at a glance

The degree of roasting of coffee beans is one of the important factors that affect the taste and flavor of coffee. Different degrees of roasting will produce different aromas, acidity and bitterness of coffee beans. This article will gradually introduce the effects of various degrees of roasting on the taste and flavor of coffee from light roasting to dark roasting.

Light Roast

Light roasting means that the coffee beans are gently processed at low temperature, so that their surface turns golden yellow. This degree of roasting retains most of the original flavor, making the coffee have a bright and refreshing acidity, and a rich and fragrant fruity aroma.

Since it is not exposed to high temperatures for too long, the light roasted coffee beans produce more active substances such as vitamin C, so it is healthier! However, because it has not been processed at high temperatures, the oil content is lower. Therefore, it tastes lighter and does not feel greasy. Moreover, the lightly roasted coffee beans are full of water, so it is easier to produce fine powder when grinding.

Medium Roast

Medium roasting means that the coffee beans are processed until the surface presents a darker brown color. This degree of roasting causes chemical changes inside the coffee beans, releasing more complex and rich aromas. At the same time, the acidity gradually weakens and the bitterness increases.

Medium degree of roasting can balance the relationship between original flavor and fresh aroma, and the taste is smooth, sweet and mellow. Because it has been processed at high temperature for a certain period of time, the fat content is relatively increased. But it has not reached the extreme, so it will not taste light or greasy.

Dark roast

Deep roasting means processing the coffee beans until the surface is very dark or even close to black. This degree of high temperature treatment makes the sugar and acidity inside the coffee beans almost completely converted into a bitter caramel taste. Deep roasting produces a rich and strong bitter taste, and also brings some caramel aroma.

Deep roasting will make the coffee beans lose most of their original flavor, so the taste is relatively simple compared to the first two. It tastes richer and more bitter, but it is also more likely to cause gastrointestinal discomfort. The fat content is the highest, so the taste is greasy.

Summarize

Whether it is light roasting, medium roasting or deep roasting, each degree has its own characteristics and applicable scenarios. Choosing the right degree of coffee beans can be adjusted according to personal taste preferences. If you like fresh and bright fruity aroma and sour taste, then light roasting is a good choice; if you pursue complex and rich aroma and can accept a certain degree of bitterness, then medium roasting may be more suitable; and if you love strong bitterness and rich caramel aroma, then deep roasting will be your first choice.

No matter which degree of roasting you choose, you need to pay attention to keeping the coffee beans fresh. Because coffee beans will continue to release carbon dioxide after roasting, if not stored properly, they will oxidize and deteriorate. Therefore, it is recommended to buy whole coffee beans and grind them before use.
