The magical transformation of coffee beans into fragrant coffee!

Coffee, this magical drink originating from Africa, has become an indispensable part of people's lives. However, have you ever wondered how coffee beans become fragrant coffee? Let's uncover this magical transformation process together.

First, we need to start by choosing the right coffee beans. There are many types of coffee beans in the world, each with its own unique flavor and characteristics. After deciding which beans to use, the next step is roasting.

Roasting is the process of heating green coffee beans to a high temperature and for a long enough time to change their chemical properties and flavor characteristics. Under high temperature, the green beans that were originally green, hard and could not be drunk directly gradually lose moisture and release an intoxicating aroma. At the same time, chemical reactions occur during the roasting process, causing the internal structure to change and produce a variety of pleasant tastes.

Over time, with proper control of the heat, time and temperature, the coffee beans gradually become burnt black and a layer of oil forms on the surface. This is because the starch and protein inside the beans are broken down and oxidized during the roasting process, producing rich aroma substances.

The next step is grinding. Put the roasted coffee beans into a special coffee machine or a manual grinder and grind them finely. Different types of coffee require different degrees of coarseness to extract the best taste.

The last step is brewing! Pour the right amount of ground coffee into the filter and add the right amount of boiling water. After waiting for a few minutes, the fragrant and tempting coffee with a slightly bitter taste, a balance of sweet and sour, and a rich and smooth taste is ready.

From choosing the right type to brewing a cup of delicious coffee, the whole process is full of magical transformations. Each link plays a vital role in the final cup of delicious coffee in front of us. Let's enjoy the wonderful experience brought by this magical transformation process!
