The basic knowledge of coffee is revealed to make you a coffee expert!

Coffee is a popular drink that not only has a refreshing effect, but also has a rich taste and culture. To become a true coffee connoisseur, in addition to tasting different types of coffee, you also need to know some basic knowledge about coffee. The following will reveal these common sense and help you better understand and appreciate this delicious drink.

1. Coffee beans and origin

The first thing to understand is the relationship between coffee beans and where they come from. There are two main mainstream markets in the world: Arabica and Robusta. Arabica beans are generally considered to be high-quality, high-value and more complex taste options; while Robusta beans have a higher content, a more bitter taste and more body.

In addition, when choosing to buy, you should also note that the beans produced in each country or region will produce unique flavors due to different climates, soils and growing methods. For example, coffee beans produced in Brazil often have nutty and chocolate flavors, while Ethiopia is known for its floral and fruity taste.

2. Coffee roasting degree

Coffee beans need to go through the important step of roasting during the processing. The degree of roasting plays a vital role in the taste and flavor of coffee. Generally speaking, light roasting will retain more original flavors and have higher acidity; medium roasting will balance the sweet and sour and add some cocoa or nut aroma; deep roasting will bring a richer, bitter and obvious cocoa or wood aroma.

Therefore, when choosing to buy, you can choose coffee beans that suit your taste according to your preferences.

3. Coffee brewing method

Different brewing methods will also affect the final coffee taste and flavor. Here are some common brewing methods:

- Drip coffee: Use a paper filter and a drip device to slowly pass hot water through the coffee grounds. This method is good for extracting a light, smooth taste.

- French press: Ground coffee is steeped with hot water and then pressure is applied to separate the grounds. This method extracts a rich, full-bodied flavor.

- Espresso Machine: Uses high-pressure steam or water to quickly brew a small but rich cup of espresso.

4. Storage and preservation

To maintain optimal flavor, proper storage and preservation are essential. Here are a few key points:

- Storage: Unopened coffee beans should be stored in a dry, cool place away from direct sunlight. The opened packaging bags should be sealed and used within two weeks.

- Grinding time: It is best to grind the coffee beans freshly before brewing, because the increased surface area of ​​the coffee powder makes it more susceptible to oxidation and loss of flavor.

- Frozen storage: If you need to store the coffee beans for a long time, you can put them in a sealed bag and put them in the freezer. However, be careful to avoid frequent thawing and re-refrigeration to avoid affecting the taste.

5. Caffeine Content

The last piece of common sense is about the caffeine content. Generally speaking, Robusta beans contain more caffeine than Arabica beans. In addition, different types and brands of coffee will also vary.

For sensitive people or those who don’t want to disrupt their sleep by drinking at night, there are low-caffeine or decaffeinated options.

Conclusion

By understanding these basic common sense, I believe you have a clearer understanding of how to become a true coffee expert. Remember to pay attention to your own preferences while tasting various types and origins, and explore ways to enjoy this delicious drink that suit your taste and preferences.
