Coffee bean roasting degree: from light to dark, explore the aroma and flavor of coffee

Light roasted coffee beans

Lightly roasted coffee beans refer to coffee beans that are light yellow or light brown in color during the roasting process. This degree of roasting retains the original acidity and floral aroma of the coffee beans, while giving the coffee a fresh and bright taste.

Because light roasting is performed at a lower temperature and for a shorter time, the flavors of coffees from different origins and varieties vary greatly at this level. For example, the lightly roasted Yirgacheffe coffee from Ethiopia has a fresh, floral aroma like a lightly fried protein cookie, while the coffee from the San Andres Valley in Colombia has a citrus and herbal flavor.

Medium to light fried protein cookies

Medium to light roast is between light roast and medium roast. At this stage, the temperature gradually rises and the color of the coffee beans turns into dark brown. Medium to light roast has a certain acidity and sweetness, while also retaining some of the unique flavor of the original origin.

Brazil produces medium-to-light fried protein cookies with nutty and chocolate flavors, while Antigua, Guatemala, has caramel and citrus aromas.

Medium roast

Medium roast means that the coffee beans are roasted at a higher temperature for a longer time. At this level, a shiny and slightly bitter skin will form on the surface of the coffee beans. Compared with light and medium-light fried protein cookies, medium roast is more balanced and has a richer taste.

The San Andres Valley region of Colombia produces notes of cocoa, nuts and citrus, while Kenya has notes of black currant and grapefruit.

Dark roast

Deep roasting means that coffee beans are roasted at high temperature for a long time, so that a layer of shiny and darker skin is formed on the surface of the coffee beans. At this level, the coffee beans lose the unique flavor of the original origin, but gain a rich, bitter and roasted aroma.

Italy is a country famous for its rich, deep-fried espresso. Espresso is made from coffee beans that have been deep-fried. At this level, the taste is very strong and suitable for making various special coffees such as lattes and cappuccinos.
