Overview of the origin and types of coffee beans in Nestle capsule coffee machines

The story of coffee beans began in the plateaus of ancient Egypt, where coffee plants were gradually spread around the world through centuries of cultivation. Coffee beans are mainly divided into two categories: Arabica and Robusta. Arabica beans are considered to have a more delicate taste and are usually grown in high altitudes, while Robusta beans are stronger in taste, contain more caffeine, and are suitable for low altitude environments.

Coffee beans play a vital role in coffee making. The beans release rich aroma and flavor during the roasting process, laying the foundation for the final taste of coffee. Roasted coffee beans can present a variety of flavors and styles through different grinding methods and brewing techniques, from strong espresso to refreshing hand-brewed coffee.

Understanding the types and characteristics of coffee beans is essential for choosing the right coffee beans and making coffee that suits your personal taste. Each coffee bean has its own unique flavor characteristics, which are reflected in the final coffee drink.

How to safely handle and brew coffee beans

In order to ensure the safety of coffee beans and their good taste, you first need to pay attention to the storage conditions of coffee beans. Coffee beans should be stored in a dry, cool place, avoiding high temperature and humidity, which can prevent the formation of mold and other harmful substances. Using airtight containers to store coffee beans also helps to maintain their freshness and aroma.

Before brewing the coffee beans, it is recommended to grind them appropriately. The coarseness of the grind should be adjusted according to the brewing method used. For example, for espresso, a fine grind should be chosen, while for a French press, a coarse grind should be chosen. This ensures optimal extraction of the coffee, thus avoiding taste issues caused by over- or under-extraction.

When brewing coffee beans, it is important to use clean utensils and water. Avoid using too high a temperature or too long a brewing time to avoid over-extracting bitter substances in the coffee. Adjusting the brewing time and temperature, depending on the type of coffee and personal taste, can help achieve a balanced flavor.

Finally, it is recommended to avoid boiling whole coffee beans directly, as this method can lead to uneven extraction and poor taste. Using proven coffee brewing methods such as drip, French press or espresso can better control the quality and safety of the coffee.

Common Misunderstandings and Precautions for Brewing Coffee Beans

During the brewing process, some common misconceptions may affect the quality and safety of coffee. First, a common misconception is to boil the whole coffee beans directly. This method not only fails to effectively extract the flavor components in the coffee beans, but may also cause bitterness and uneven taste. The correct way is to grind the coffee beans before brewing, which can ensure uniform extraction of flavor.

Another common problem is overheating the coffee beans. Long-term high-temperature brewing may cause excessive release of harmful substances and bitter components in coffee, affecting the taste and possibly posing health risks. The appropriate brewing time and temperature should be controlled according to the type of coffee beans used and the brewing method to avoid this from happening.

In addition, many people ignore the importance of water quality when brewing coffee. Using water sources that contain impurities or are too hard may affect the flavor and taste of the coffee. It is recommended to use filtered water or mineral water for brewing to ensure the purity and flavor of the coffee.

Finally, coffee beans should be stored away from exposure to light and moisture, which can cause them to spoil and lose flavor. Coffee beans should be stored in a dry, cool place and in airtight containers.
