When we talk about coffee, many people's first reaction is the rich aroma and refreshing bitter taste, but how is coffee born? What are its raw materials? Let's walk into the world of coffee and explore how coffee beans transform into the cup of mellow drink in our hands.

1. Raw materials of coffee

The main raw material of coffee is coffee beans, which are the seeds of the coffee tree fruit. The coffee tree is an evergreen small tree that needs to be planted in tropical or subtropical regions because it has extremely high requirements for temperature and humidity. After the ripe coffee berries are picked, the coffee beans inside will be taken out and processed.

Coffee beans have different flavors depending on the type. Arabica and Robusta are the two most common coffee beans on the market. They differ in origin, color, and taste, providing rich options for coffee making.

2. Coffee Bean Processing

The coffee bean processing process can be roughly divided into the following steps:

1. Cleaning and screening : The picked coffee beans first need to be cleaned to remove the pulp and other impurities. Then, through the screening process, unqualified beans and beans of inconsistent size and maturity are separated.

2. Fermentation : Fermentation is a very important step in coffee bean processing. It can transform the substances inside the coffee beans and lay the foundation for the subsequent roasting process. The fermentation time and temperature will affect the final flavor of the coffee beans.

3. Drying : The fermented coffee beans need to be dried to stop the fermentation process and fix the aroma of the coffee beans. The drying process also needs to strictly control the temperature and humidity to ensure the quality of the coffee beans.

4. Roasting : Roasting is the most critical step in the coffee bean production process. Different roasting degrees will produce different tastes and aromas of coffee beans. Light and medium roasted beans have a mellow taste, while dark roasted beans have a rich caramel flavor.

In this process, the roaster is like a master chef. They master the secrets of time and temperature, transforming ordinary coffee beans into golden brown delicacies.

5. Grinding : Grinding is the process of turning roasted coffee beans into powder suitable for brewing. Different degrees of grinding will affect the taste and extraction speed of the coffee. Fine grinding is suitable for making espresso, while coarse grinding is more suitable for making French press coffee.

3. Coffee Making

With the properly processed and ground coffee beans, the next step is to make coffee. Common methods include brewing, boiling, and using a coffee machine. Each method will affect the taste and flavor of the coffee.

During the brewing process, the water temperature, brewing time and the ratio of coffee beans to water are all key parameters, which together determine whether the cup of coffee has a mellow taste and overflowing aroma.

The coffee machine quickly releases the aroma and flavor of coffee beans through high-pressure steam or hot water extraction, providing us with cup after cup of fragrant coffee.

Making coffee is a complex and artistic process. From planting coffee trees to enjoying coffee in a cup, every link embodies people's hard work and wisdom. Coffee is not only a drink, but also a culture and a lifestyle. When we hold a cup of coffee, we are also savoring a story about life and hard work.
