Why is it so important to care for coffee beans for seven days after roasting?

Coffee is one of the most popular beverages in the world, and the roasting process of coffee beans plays a vital role in the formation of flavor and taste. However, many people may not know that after roasting, coffee beans need to go through a specific period of time. This stage usually lasts about seven days and is considered necessary to ensure that the coffee reaches the best flavor and quality level.

1. What happens to coffee beans during the roasting process?

Before we understand why seven-day coffee bean care is so important, we first need to understand what happens to coffee beans during the roasting process. After the raw coffee berries are picked, peeled, fermented, etc., they are processed by untreated raw sun drying or wet treatment (washing) and directly dried and stored without any processing or packaged and shipped to all parts of the world for on-site manual selection and grading; then they enter the roasting machine for roasting. During the roasting process, the internal structure of the coffee beans undergoes major changes. First, the water begins to evaporate and the coffee beans begin to expand. As the temperature rises, the acidic substances inside the coffee beans gradually decompose and produce a series of complex and diverse compounds.

2. Why does it take seven days to grow beans?

After roasting, the coffee beans need to go through a curing phase for a specific period of time. This phase usually lasts about seven days and is considered necessary to ensure that the coffee reaches the best flavor and quality level.

First, the complex compounds formed during the roasting process need time to stabilize and interact with each other. These compounds include acids, aromatic compounds, and bitter components, among others. By allowing the coffee beans to rest naturally during the seven-day curing period, these complex compounds can better combine and form a more balanced and rich flavor.

Secondly, soon after roasting, coffee beans will produce an odor called "roasted flavor" due to the presence of residual carbon dioxide. This odor may mask the flavor characteristics of the coffee itself. After seven days of bean curing, the carbon dioxide is gradually released and the roasted flavor gradually dissipates, allowing the original flavor of the coffee to be better displayed.

In addition, during the seven-day bean-raising period, the coffee beans will undergo a series of chemical reactions and physical changes. For example, the acidity gradually decreases, the bitterness decreases, the sweetness increases, etc. These changes help improve the taste and balance of the coffee.

3. How to grow beans in seven days?

There are several key factors to consider when growing beans for seven days:

Storage environment: Coffee beans need to be stored in a dry, ventilated and light-proof environment. Too high or too low humidity may have an adverse effect on the quality of coffee.

Container selection: It is also very important to choose a suitable container to store coffee beans. It is best to choose an airtight container to prevent the coffee beans from coming into contact with the outside air.

Storage time: Seven days of bean curing is a relatively fixed time period, but it can also be fine-tuned according to personal taste and preference. Some people may prefer to taste coffee immediately after the bean curing period is over, while others believe that a longer bean curing period can bring better flavor.

4. The impact of seven-day bean-raising on coffee flavor

After seven days of aging, the flavor of the coffee will change significantly. First, the acidity will become more balanced and softer. After a short storage period, the acidic substances will gradually degrade and interact with other compounds to form new complex flavors.

Secondly, after the carbon dioxide is released within seven days, the "roasted smell" dissipates and the original flavor is better revealed. This allows the coffee to show its unique aroma, taste and sweetness.

In addition, within seven days, the bitter components decrease and the sweetness increases, making the coffee taste more balanced and smoother.

in conclusion

Seven days of bean aging is necessary to ensure that the coffee reaches the best flavor and quality level. By allowing the coffee beans to rest naturally for about seven days after roasting, complex compounds are stabilized and interact with each other, carbon dioxide is gradually released, the roasting smell dissipates, and a series of chemical reactions and physical changes occur. These changes make the coffee flavor more balanced, rich, and soft, and improve the smoothness of the taste. Therefore, before tasting a cup of delicious coffee, please wait patiently for the seven-day bean aging period to end.
