How long does it take for coffee beans to grow after roasting?

Coffee bean curing time after roasting

Coffee bean roasting is to process raw beans at high temperatures to cause chemical changes inside them, thus producing special aroma and flavor. However, roasted coffee beans cannot be used immediately, but need to be aged for a period of time to reach the best quality. So, how long does it take to age roasted coffee beans? Let's discuss this in detail.

1. The bean-raising time is related to the degree of roasting

First of all, we should make it clear that different degrees of roasting will have different effects on coffee beans and require different lengths of bean-raising time to achieve the best quality. Generally speaking, light and medium roasts (such as light roasting and medium roasting) require longer bean-raising time; while deep and ultra-deep roasts (such as full city and French roasting) require relatively less bean-raising time.

Specifically, for coffees with a light taste such as light roast and medium roast, proper bean curing for 1-2 days or even longer can make the aroma more stable and the flavor richer. For deep roasted coffees such as full roast and French roast, generally only a shorter bean curing period is needed.

2. The time required to grow beans depends on the type of coffee

In addition to the degree of cafe roasting, different types of coffee will also affect the bean-raising time. For example, the two main varieties, Arabica and Robusta, need some time after roasting to release the best flavor.

Arabica coffee beans usually need a longer resting time because they have higher acidity and floral and fruity aromas. After a proper resting period, these characteristics will be better displayed and the taste will become more balanced and soft.

Robusta coffee, by contrast, is relatively insensitive and reaches its best quality after a short rest period, due to its naturally low acidity and rich, robust taste.

3. Other factors affecting soybean growing time

In addition to the degree of iced American English roast and the type of coffee, there are other factors that will affect the bean-raising time.

The first is the storage method of coffee beans. If the roasted coffee beans are sealed and stored in a light-proof, moisture-proof, low-temperature environment, their shelf life can be extended, and it takes a longer time to grow the beans to achieve the best quality.

The second is climate conditions. A high temperature and high humidity climate will accelerate the aging process of coffee beans, thereby shortening the bean-raising time; while a dry and cold climate will have the opposite effect.

4. How to determine the best time to grow beans

It is not easy to determine the best time to grow beans, because it is affected by many factors. Different people have different preferences for flavor and aroma. However, in practice, we can judge by the following methods:

- Observe the color: Generally, freshly roasted coffee will have a bright, rich and uniform color; as the storage time increases, the color will gradually darken.

- Smell the aroma: Freshly roasted coffee beans usually have a stronger aroma, but this does not mean that they have reached the best quality. By smelling once a day, you can observe whether the aroma is stable.

- Grinding test: Grind the coffee beans into powder and try brewing with water. Just after roasting, some green or grassy smells may appear; as the beans grow longer, these smells will gradually disappear.

Summarize

In summary, there are many factors to consider when determining the best bean curing time. Whether it is light or dark roasting, Arabica or Robusta, storage method and climate conditions will affect the bean curing time. However, in practice, we can judge the best bean curing time by observing the color, smelling the aroma and performing grinding tests. I hope this article can help you better understand and master the bean curing time after roasting coffee beans.
