Coffee bean roasting degree and characteristics: at a glance

Coffee is one of the most popular beverages in the world, and different roasting degrees give coffee beans different characteristics and tastes. In this article, we will explore the effects of different roasting degrees on coffee beans and introduce their respective characteristics.

Light Roast

Light roasting means heating the coffee beans until the first crack is reached and then stopped. This degree of roasting usually retains most of the flavor and acidity of the original coffee beans. Light roasting produces a bright, fresh and floral taste with fruity flavors such as citrus and grapefruit. In addition, since there is not too much time exposed to high temperatures, light roasting can also retain more of the flavor from the soil and climate conditions of the origin.

Medium (City) Roast

Medium (city) roasting is done after the first crack and then at a higher temperature. This level of roasting produces darker beans with a more balanced acidity and sweetness. When roasted medium, oils begin to form inside the beans and there will be some slight bitterness. On the palate, medium roasting usually has chocolate, nuts and slight fruit aromas.

Medium-dark (French) roast

Medium-dark (French) means that the heating process is stopped before the second crack. This degree of roasting produces darker, glossier and slightly shiny coffee beans. Due to the longer high temperature, the oil content inside the coffee beans increases, so it has a rich and full taste and aroma. Chocolate, nuts and some subtle but pleasant sweetness can often be tasted in medium-dark roasts.

Depth (French/Italian) Level

The last level is to continue heating the coffee beans after the second crack. Deep roasting produces extremely dark, shiny and smooth coffee beans, which are usually used to make strong espresso. This degree of roasting releases a large amount of oil inside the coffee beans, so the taste is full, bitter, and has aromas such as caramel and chocolate.

Summarize

Different degrees of roasting give coffee beans their own unique flavor and aroma. Light roasting retains the original flavor and acidity, medium and medium-dark levels provide a more balanced and complex taste experience, and dark levels emphasize bitterness and rich aroma. Choosing coffee beans that suit your taste preferences is the key to tasting delicious coffee.
