Coffee roasting: the golden formula of temperature and time

introduction

Coffee roasting is an art, and temperature and time are key factors in determining the taste of coffee. During the roasting process, proper control of temperature and time can give coffee beans the best flavor and aroma. This article will focus on the golden formula of temperature and time, and introduce how to roast delicious coffee by properly adjusting these two parameters.

Section 1: Understanding the temperature and time of different stages

In the baking process, it can be divided into four main stages: preheating, alternating dry and wet, development stage and cooling. Each stage has different temperature requirements and duration.

The second stage: warm-up phase

Preheating means adding coffee beans to the machine that has reached the appropriate temperature (usually 200°C) and allowing the beans to be heated evenly. This process usually takes 1-2 minutes.

The third stage: alternating wet and dry phase

At this stage, water starts to evaporate from the beans and pressure builds up. The temperature should be kept at around 200°C for about 3-4 minutes.

The fourth stage: development

The development phase is the most critical step in the roasting process. During this phase, the coffee beans begin to react chemically, releasing their aroma and flavor. The temperature is gradually raised to around 220°C and maintained for a certain period of time (usually 2-4 minutes).

The fifth stage: cooling stage

After roasting, the coffee beans need to be cooled quickly to stop the chemical reaction. Pour the hot coffee beans into a cool container and use a fan or other tool to cool them quickly.

Section 6: Tips for adjusting temperature and time

In addition to understanding the temperature and time requirements for different stages, there are some tips that can help us better master the golden formula:

• Observe the color: Determine whether it has reached the ideal state by observing the changes in the color of the coffee beans.
• Experiment with different parameters: Try different temperature and time combinations to find the roasting method that works best for your taste.
• Take notes: Record the temperature and time after each baking so that you can make adjustments and improvements.

in conclusion

By properly controlling the temperature and time, we can roast coffee with a rich taste and strong aroma. The temperature and time requirements at different stages are different and need to be adjusted according to the actual situation. At the same time, mastering some skills can help us better grasp the golden formula. I hope this article will help you understand the importance of temperature and time in the coffee roasting process.
