Coffee Bean Roasting: The Golden Formula of Time and Temperature

introduction

Coffee roasting is an art. By controlling the time and temperature, the flavor and aroma of coffee beans can be maximized. This article will focus on the golden formula of time and temperature to introduce how to roast high-quality coffee beans.

Understanding time and temperature

In the roasting process, time and temperature are inseparable. Time determines how long the coffee beans are heated, while temperature affects the rate of chemical reactions inside the coffee beans. Proper control of these two factors can achieve the best quality coffee beans.

Light roasting: high temperature, short time

Light roasting means heating the coffee beans to a higher temperature and completing the whole process in a relatively short time. This method is suitable for single-origin coffees with prominent acidity and fresh taste.

Medium roast: balanced control

Medium roasting is a process that is performed at a lower temperature than light roasting and is completed over a relatively long period of time. This method is suitable for most coffee beans and can achieve a balanced taste of acidity, sweetness, and bitterness.

Dark roasting: low temperature, long time

Dark roasting means heating the coffee beans to a lower temperature and processing them for a relatively long time. This method is suitable for coffees that want to emphasize bitterness and a strong taste.

Controlling the baking process

In addition to choosing the right baking method, you also need to pay attention to the following points to control the entire baking process:

1. Preheating: Before starting formal heating, preheat the device to the required temperature to ensure stability.
2. Monitor the temperature: Use a professional thermometer or instrument to monitor the internal and ambient temperature of the coffee beans, and adjust the heat in time.
3. Observe color changes: Determine whether the ideal state has been reached by observing the color changes on the surface of the coffee beans.
4. Cooling process: After roasting, the coffee beans are quickly cooled to stop heat conduction and chemical reactions.

Conclusion

Time and temperature are the golden formula for coffee roasting. By properly controlling these two factors, you can roast high-quality coffee beans with different flavor characteristics. I hope this article will help you understand coffee roasting.
