Coffee Bean Roasting Temperatures: Discovering the Ideal Roast

introduction

Coffee is one of the world’s most popular beverages, and the degree to which the beans are roasted has a significant impact on the taste and flavor of the coffee. This article will explore the ideal roasting degree and discuss the effects of different temperatures on coffee beans.

background

During the roasting process, coffee beans undergo chemical and physical changes. As the temperature rises, the water inside the coffee beans evaporates and oxidation reactions occur, producing complex and diverse aroma substances. Therefore, controlling the roasting temperature can adjust the content and proportion of these aroma substances.

Low temperature baking

Low-temperature roasting is usually carried out between 180°C and 205°C. This method can retain more original flavors and make the acidity more obvious. However, roasting at a low temperature will cause the internal moisture to escape more slowly, making the surface prone to overexposure.

Medium temperature baking

Medium temperature roasting is usually carried out between 205°C and 220°C. This method can balance the acidity and bitterness and produce a more balanced taste. In addition, medium temperature roasting can also form a thin layer of oil on the surface of coffee beans, which increases the aroma of coffee.

High temperature baking

High temperature roasting is usually carried out at above 220°C. This method will cause the moisture inside the coffee beans to evaporate quickly and produce more bitter substances. Although high temperature roasting can bring a rich and deep flavor to coffee, it can also easily lead to overexposure and bitter taste.

Ideal roasting degree

The ideal roasting degree is a subjective and complex issue, because everyone has different preferences for taste and flavor. However, before pursuing the ideal, we need to understand the effects of different degrees on coffee beans and choose the appropriate method according to our preferences.

in conclusion

By exploring different roasting temperatures, we can find that each degree has its own unique flavor and characteristics. Low-temperature roasting retains the original flavor, medium-temperature roasting balances the sourness and bitterness, and high-temperature roasting brings a rich and deep flavor. Therefore, when choosing coffee beans, we can choose the appropriate degree according to our preferences for taste and flavor.
