Coffee Bean Roasting Degree Analysis: The Difference Between Light Roast, Medium Roast and Dark Roast

The difference between light roast, medium roast and dark roast

The degree of roasting of coffee beans has an important influence on the taste and flavor of coffee. During the roasting process, coffee beans will undergo different degrees of heating, resulting in different chemical changes. These changes will cause the coffee beans to present different colors, aromas and tastes. Light roast, medium roast and dark roast are three common roasting degrees, and there are obvious differences between them.

Light roast

Light roasting means heating the coffee beans to a relatively low temperature (about 180-205 degrees Celsius) and then stopping the roasting quickly. This short heating only makes the surface of the coffee beans slightly brown, while the inside remains bright yellow or light brown. Since they have not been heated at high temperatures for a long time, light roasted coffee beans retain more of their original flavor.

When you pour a cup of freshly brewed light roasted premium hand-brewed coffee into a cup, you can first smell a strong floral aroma, and the taste is refreshing, high in acidity, bright in flavor, with some fruit and floral notes. Light roasted coffee beans have a higher acidity and relatively low bitterness. This degree of roasting is suitable for coffee lovers who like a fresh taste and obvious acidity.

Medium Roast

Medium roasting means heating the coffee beans to a medium temperature (about 210-220 degrees Celsius) and then stopping the fire. This degree of heating makes the surface of the coffee beans appear dark brown, and the inside begins to become more evenly brown. Compared with light roasting, medium roasting will cause more chemical reactions and aroma in the coffee beans.

The Zhongpei premium hand-brewed coffee has a relatively balanced taste and flavor. It retains the original flavor to a certain extent, and adds some sweetness and bitterness caused by the short high temperature. When pouring it into the cup, you can smell a mixture of chocolate, nuts or rich fruits. The acidity of medium roasted coffee beans is lower than that of light roasted coffee beans, and the bitterness and sweetness are relatively balanced. This degree of roasting is suitable for most people's taste.

Dark roast

Dark roasting means heating the coffee beans to a relatively high temperature (about 225-230 degrees Celsius) and then stopping the roasting. This degree of heating makes the surface of the coffee beans very dark, almost black, and the inside becomes more uniformly brown or black. Due to long-term high-temperature heating, dark roasting will make the coffee beans produce more oil and bitterness.

When you pour a cup of freshly brewed deep roasted premium hand-poured coffee into a cup, you can smell a strong and rich aroma, with obvious complex aromas such as cocoa, chocolate, and nuts. In terms of taste, the deep roasted premium hand-poured coffee has the characteristics of rich and full, lasting sweetness, and slight bitterness. Due to long-term high-temperature heating, the acidity of deep roasted coffee beans is low, and the bitterness and sweetness are relatively strong. This degree of roasting is suitable for coffee lovers who like a strong and bitter taste.

Summarize

Coffee beans with different roasting degrees bring different flavors and taste experiences. Light roasting retains the original flavor, fresh and sour; medium roasting balances the taste and aroma; dark roasting has a strong and complex fragrance. Choosing the roasting degree that suits your taste can allow us to better enjoy the wonderful experience brought by coffee.
