Eight basic knowledge of coffee

Coffee is a popular drink with a rich taste and unique aroma. Before enjoying coffee, knowing some basic knowledge about coffee can help us better appreciate and understand this delicious drink. This article will introduce the eight basic knowledge of coffee.

1. Coffee Beans

Coffee beans are the raw material for making coffee, and usually come from two main varieties: Arabica and Robusta. Arabica beans have higher quality, lower factor content, and a more complex and softer taste; while Robusta beans have a higher factor content, a stronger and bitter taste. Different types of coffee beans will bring different flavor characteristics to people.

2. Roasting degree

The degree of roasting determines the chemical composition of the coffee beans and the final taste. Generally, there are three levels: light roasted, medium roasted, and dark roasted. Light roasted coffee beans have a brighter color, high acidity, and a refreshing taste; medium roasted coffee beans have a darker color, moderate acidity, and a balanced taste; while dark roasted coffee beans have a darker color, high bitterness, and a strong taste.

3. Coffee Grinding

Grinding is one of the most important steps in making coffee. Different types of grinders produce coffee powder of different coarseness. Usually divided into three levels: fine, medium and coarse. Fine ground coffee powder is suitable for espresso machines; medium is suitable for drip or French press pots; and coarse is suitable for cold brew or hand brew.

4. Storage

Proper storage and preservation of coffee can extend its shelf life and maintain its best flavor. Keep the unopened packaged whole bag in a cool and dry place away from exposure to sunlight and moisture. Once opened, it is recommended to transfer the coffee beans to an airtight container and store in the refrigerator or other cool place.

5. Coffee Extraction

Coffee extraction is one of the key steps in making coffee. When hot water comes into contact with coffee powder, the water dissolves the chemicals in it, forming the concentrated liquid we love. Different types of extraction methods include drip, espresso, French press, and hand brew.

6. Additives

Many people like to add cream, sugar or other condiments to coffee to increase the taste and flavor. However, additives will change the flavor characteristics of the original coffee itself, so please choose whether to use them according to your personal taste.

7. Catechin Content

Catechins are naturally present in coffee beans and have antioxidant properties. Different roasting levels and types of beans affect their content. Lighter roasts and Arabica beans generally contain higher levels of catechins, while darker roasts and Robusta beans contain lower levels.

8. Caffeine Content

Caffeine is a stimulant found naturally in coffee. Different types and roasting levels of coffee beans can affect its content. Generally speaking, Robusta beans have a higher caffeine content than Arabica beans.

By understanding these eight basics, we can better taste and appreciate every delicious cup of coffee. Whether it is choosing the right grind, extraction method or additives, we can make our favorite cup of coffee according to our personal taste.
