Coffee bean curing time after roasting

Coffee bean roasting is one of the important steps for coffee shop copywriters to make delicious coffee. However, the roasted coffee beans need to be aged for a period of time to reach the best quality. So, how long does it take to complete the bean-raising process? This article will focus on this.

What is soybean farming

During the roasting process of coffee beans, due to the high temperature and oxygen, chemical reactions will occur inside the coffee, releasing substances such as carbon dioxide. These substances will have an adverse effect on the taste of coffee, making it bitter or bland.

Therefore, after roasting, we need to give the coffee enough time to release these harmful substances and stabilize them. This process is called "bean cultivation".

Time Factors Required for Growing Beans

1. Raw material variety: Different types of coffee require different bean curing time after roasting. Generally speaking, coffee beans with higher acidity require longer curing time.

2. Roasting degree: The deeper the roasting degree, the higher the carbon dioxide content inside the coffee, and the longer the bean-raising time will be.

3. Storage environment: Coffee beans are affected by environmental factors such as temperature and humidity during storage. A suitable storage environment can accelerate the bean growth process.

Common bean growing time

1. Light roasting: Light roasting usually stops roasting the coffee after the first crack. In this case, due to the release of less carbon dioxide, the bean curing time is relatively short, about 24-48 hours.

2. Medium roasting: The coffee is heated until the second burst ends and then stopped. More carbon dioxide is released and the internal structure of the coffee is more stable. Therefore, the time required for a medium roast is usually 48-72 hours.

3. Deep/Heavy Roasting: Deep roasting continues to heat the coffee until the third burst ends and then stops. This level of roasting will release more carbon dioxide from the coffee beans, so the roasting time is relatively long, usually more than 72 hours.

Precautions during soybean cultivation

1. Keep ventilation: During the bean cultivation process, it is necessary to keep the air around the coffee beans circulating. This helps to remove harmful substances such as carbon dioxide and promote the improvement of coffee taste.

2. Control humidity: Properly controlling the humidity of the storage environment can accelerate the bean-raising process. Generally speaking, the relative humidity is more suitable between 60-70%.

3. Avoid direct sunlight: Sunlight can cause coffee to deteriorate and lose its aroma. Therefore, it should be kept away from direct sunlight during storage.

in conclusion

Generally speaking, light roasting takes the shortest time, while deep/heavy roasting takes the longest time. However, in actual operation, there is no fixed standard. The length of the bean-raising time will also be affected by other factors, such as the quality of the coffee beans, the storage environment, etc.

Therefore, when making coffee, we need to judge the bean-raising time according to the specific situation and make appropriate adjustments. Only after sufficient bean-raising can the coffee achieve the best taste and aroma.
