Coffee Bean Science: From Planting to Roasting, Learn the Secrets of Coffee!

Coffee is a popular drink with a long history and rich cultural connotations. To understand the secrets of coffee, we need to gradually uncover its mystery from planting to roasting.

First, coffee beans are extracted from the fruits of coffee trees. These fruits will appear bright red or yellow when ripe. Farmers will carefully select the fruits of appropriate maturity for picking, peeling, fermenting and washing. Next, they will dry the processed beans and grade and sort them.

Then, the processed coffee beans are transported to the roasting plant for roasting. In this process, temperature and time are very critical factors. By controlling the different temperatures and durations, coffee beans with different tastes and flavors can be adjusted.

When the beans begin to heat, they react chemically and release substances such as aroma, oils and carbon dioxide. Over time, the color of the beans will gradually change from green to light brown and then to dark brown. In this process, the moisture inside the coffee beans will also be evaporated.

Finally, after roasting, the coffee beans need to be cooled and stored. This will preserve their freshness and taste. Generally speaking, freshly roasted coffee beans are most delicious within two weeks.

In summary, understanding the process of coffee from planting to roasting can help us better appreciate and taste this delicious drink. Behind every cup of fragrant coffee are the hard work of countless farmers, pickers and roasters.
