Roasting, grinding and brewing coffee beans: the whole process of perfectly presenting the aroma of coffee

The process of roasting coffee beans

Roasting is one of the key steps to making a delicious coffee. During this process, coffee beans undergo a series of chemical changes, which release a rich aroma and taste. First of all, it is very important to choose high-quality coffee beans. High-quality coffee beans usually have uniform size, complete shape and smooth surface.

Next, the coffee beans are placed in the roaster for heating. Before starting the heating, the appropriate temperature and time need to be set in advance. Different types and varieties of coffee beans require different levels of heating to achieve the best results.

Get the right temperature

The temperature is one of the most important factors that determine the strength and softness of the coffee flavor. During the entire heating process, we need to pay close attention to indicators such as color changes and special sounds coming from inside the machine.

Soon after you start heating, you will hear the first "pop" sound - this is called the "first crack". This means that the water inside the coffee bean has begun to evaporate and the coffee bean is gradually changing color. As time goes by, you will hear more "pop" sounds, each representing the chemical reaction inside the coffee bean.

Grinding coffee beans

Grinding is one of the key steps to brewing the perfect cup of coffee. Freshly ground coffee releases more aroma and taste, so it is best to do it a few minutes before brewing.

Choosing the right grind size is important. If you use a drip brewing method, a medium-fine or slightly coarse grind is best. For an immersion brewing method (such as a French press), a finer, more even grind is needed.

Brew the perfect cup of coffee

After completing the above two steps, we can start making a perfect cup of fragrant coffee. Here are some common brewing methods:

1. Drip brewing: Put the ground coffee powder into the filter paper, pour in an appropriate amount of hot water, and let the water slowly penetrate through the coffee powder. This method is simple and easy, suitable for daily use.

2. French press brewing: Put the ground coffee powder into the French press, add appropriate amount of hot water and stir well. After waiting for a few minutes, press the piston to let the coffee seep out. This method can fully release the aroma and taste of the coffee beans.

3. Hand brewing: Sprinkle the ground coffee powder evenly on the filter and slowly pour boiling water at a certain height above the pre-humidified filter. Adjust the soaking time and soaking depth by controlling the water injection speed and angle.

Enjoy the delicious taste

Finally, after completing all the above steps, we can finally taste a cup of perfectly presented and mellow coffee! Whether it is to start a new day in the morning or to relax during the afternoon break, a cup of mellow coffee can bring us pleasant enjoyment.

Remember to master the details of each step in the roasting, grinding and brewing process, and adjust each parameter according to your taste. Only by constant trial and practice can you find the perfect coffee that best suits your taste.
