Exploring coffee bean roasting degrees: from light roasting to dark roasting, tasting the multiple flavors of coffee

The refreshing acidity of light roasted coffee

Light roasted coffee refers to coffee beans that are roasted to a lighter color, usually between tan and medium brown. This roasting method retains the original flavor of the coffee beans themselves, making the taste more refreshing. A cup of light roasted coffee usually has a bright and lively acidity with a citrus or lemon-like fruity aroma.

Due to the short-term high-temperature treatment, there are still some incompletely decomposed substances in light roasted coffee, such as amino acids and proteins. These substances give light roasted coffee special flavor characteristics. For example, when cultivating high-quality Arabica varieties from the Andes region of Colombia, we can taste a pleasant and fascinating citrus taste.

Rich and varied flavors at medium roast

Medium roasting is achieved when coffee beans are subjected to high temperatures for a slightly longer period of time. This roasting method changes the color of the coffee beans to a medium-dark brown, while increasing the formation of some roast products.

Medium roasted coffees often have richer, more varied flavors, including notes of chocolate, nuts, and caramel. This is because the high temperatures create a complex and interesting chemical reaction between the proteins and carbohydrates inside the coffee bean.

Deep roasted rich taste

When the coffee beans are treated at high temperatures for a longer period of time, they are roasted to a darker color, even close to black, and covered with a shiny, oily appearance.

Deep roasting produces a lot of bitter substances inside the coffee beans and significantly reduces the acidity. Correspondingly, we can taste a rich and full taste, leaving a lasting and unforgettable aftertaste on the tip of the tongue.

Flavor changes caused by different roasting degrees

By comparing light roast, medium roast and dark roast, we can find out the effect of different roasting degrees on the flavor of coffee. Light roast has the characteristics of freshness and acidity, suitable for people who like bright taste and citrus aroma. Medium roast adds more complex and rich taste on the basis of retaining the original flavor. Dark roast provides a great choice for those who pursue a rich and balanced taste of bittersweet.

Regardless of the degree of roasting, every cup of coffee contains the efforts and care that the farmers put into the process of careful cultivation, picking and processing. Therefore, when tasting coffee, please remember to cherish every drop of flavor and experience the story contained in it with your heart.
